Hey all, I'm trying to remove the bar that has "REMOVE" spammed in red across it. Anyone able to provide some insight/help? Here is my current userChrome.css file

#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items { opacity: 0; pointer-events: none; } #main-window:not([tabsintitlebar="true"]) #TabsToolbar { visibility: collapse !important; } #sidebar-box[sidebarcommand="treestyletab_piro_sakura_ne_jp-sidebar-action"] #sidebar-header { display: none; } .tab { margin-left: 1px; margin-right: 1px; } /* Remove close button*/ .titlebar-buttonbox-container{ display:none }

For the past few weeks I’ve seen Firefox use up more memory in MacOS Activity monitor with less tabs. I really don’t feel like troubleshooting it though.

Summary

• Mozilla has released security updates for Firefox and Thunderbird to fix a critical zero-day vulnerability that has been actively exploited in the wild.

• The vulnerability, tracked as CVE-2023-4863, is a heap buffer overflow flaw in the WebP image format that could allow an attacker to execute arbitrary code on the victim's computer.

• The vulnerability is suspected to target individuals who are at an elevated risk, such as activists, dissidents, and journalists.

• Mozilla has released Firefox 117.0.1, Firefox ESR 115.2.1, Firefox ESR 102.15.1, Thunderbird 102.15.1, and Thunderbird 115.2.2 to fix the vulnerability.

• Google has also released a fix for the vulnerability in Chrome.

Additional Details

• The WebP image format is a modern image format that is designed to be more efficient than other image formats, such as JPEG and PNG.

• The heap buffer overflow vulnerability occurs when Firefox or Thunderbird attempts to decode a specially crafted WebP image.

• The vulnerability could allow an attacker to execute arbitrary code on the victim's computer by tricking them into opening a malicious WebP image.

• Mozilla and Google have been working to fix the vulnerability since it was reported to them.

• The security updates have been released for all supported versions of Firefox and Thunderbird.

• Users are advised to update their browsers as soon as possible to protect themselves from this vulnerability.

I always had the tabs bar below the address bar and bookmark, where they obviously belong, until I recently reset firefox and now I just can't figure out how to get them back to their correct position.

How do I get the tabs between the bookmarks bar and the main browser window again?

This may occur on other sites, but I notice it often on YouTube when I fullscreen a video. To make it disappear, I have to mouse over a link that changes the URL in the bottom left. If a video is in fullscreen, I have to exit fullscreen to do that.

This issue still occurs in safe mode.

Been seeing an issue with downloading stuff from the Firefox Mobile app on Android. Sometimes when I press download on files or images, the download never actually happens; the file never appears in my phone's local files or in Firefox's download menu. There's no progress bar or any other indication that it even attempted to download. Usually only happens with either big files or when in areas of low connection. Has anyone else experienced this? Is there a fix?

An example of this is today: I went to download an image from a website while in an area of less than optimum connection. Firefox never attempted the download despite trying from birth the website and from the image in its own tab. Google Chrome was able to download the image with the same connectivity, albiet slower than normal (though it was only a second or two slower instead of being instantaneous).

I installed Firefox Flatpak on F38 and some video content is not working. Youtube and Netflix work fine, Prime Video does not. Videos on some website do not play, some give simple error messages wihtout details: NFL.com, tagesschau.de, ran.de and more do also not work.

So, something is wrong but i can not figure out what it is. . Can not figure out if it's in use or not, i guess it's not.

I did some websearch but couldn't find a solution. Does anyone of you know how to fix it?

A little while back Mozilla put out a post ushering addon developers to prep their addons but I haven't heard anything else since, I don't wanna update to early and loose everything I already got

This has been an issue for a long time. I’ve been trying to avoid Chromium based browsers, but Firefox seems to be unable to print a lot of web pages without cutting off the content between pages. This is Firefox specific, as it doesn’t happen with Chromium browsers. It’s really a pain in the ass when I need to print something I have to open another browser and print it from there. I see tons of complaints about this online going back for years. I just spent the past two hours trying (unsuccessfully) to print a recipe correctly. I eventually gave up, opened Edge and printed from there. The current state of web browsers is dogshit. It’s either give up all of your privacy or use broken stuff. Neither is good.

I'm having an issue when I try opening a game on Roblox, there's no popup and the following error message appears: "An error occurred trying to launch the experience. Please try again later." Is there anything I can do to make this work? Changing some settings or something?

I do a basic browser.local.sync sync test:

let monster = {
  name: "Kraken",
  tentacles: true,
  eyeCount: 10,
};

let kitten = {
  name: "Moggy",
  tentacles: false,
  eyeCount: 2,
};

browser.storage.sync.set({ kitten, monster });

and on the second profile:

await browser.storage.local.get("kitten");

but nothing happens, get("kitten") returns nothing.

QUESTIONS:

1. Does the synchronization work on a zip file loaded from Add-ons -> Tools for all add-ons -> Install add-on from file...?
   I have in manifest.json applications.gecko.id, as needed.
2. If not, what do I need to do to TEST the synchronization work?

Looks like the fix to add visual effects support in Google Meet for Firefox is now being rolled out

@firefox

Say I define different contexts or workspaces. So in my address bar I can type work and it will open up 5 pages that will be associated to that keyword. Then I can type bored and it will open up my 4 defined pages associated to that keyword.

I am NOT asking about pinning pages to the start/home page, and I am NOT asking about loading websites when Firefox starts up (because I don't want to always load the same things every time I launch ffox). I am also not asking about pinning tabs.

Solution: delete all bookmarks that point to an article hosted at github.blog.

Background: For the longest time, Firefox would suggest the github.blog web address whenever I type "github" into the address bar. I found that weird: yes the word "blog" starts with a letter lower in the alphabet than the word "com", but the ".com" TLD is much more popular so should show up first, right?

Right... unless you, like me, have web search suggestions turned off when entering web address into the address bar. Instead, it takes suggestions from my bookmarks and open tabs, like I instructed it.

Thus, Firefox is behaving exactly as designed and instructed, and the solution is to remove the bookmarks that point to github.blog.

I only wish I'd had recognized that sooner...

The feature is called Tab Unloading, and weirdly enough they made it not easy to access despite its usefulness.

You basically have to type about:unloads in the address bar and hit enter. If you then click on "Unload", it will put the least used tabs to sleep. If you keep clicking that button until it's greyed out, you'll have unloaded all your tabs from memory.

This feature is handy if you want to temporarily switch to something that is memory hungry without having to close your 100 tabs.

I have a habit of making windows for different things. For example, let's say I have three windows open. One for school, one for work, and one for leisure.

I want all my work tabs to persist even after closing firefox. Once I close a window, all the links get saved to the bookmark folder. I would then open the folder and start with those tabs open again.

Does anything like this exist?

I am not the author.

https://addons.mozilla.org/en-GB/android/addon/github-license-observer/

This is a cool little addon to help you tell, at a glance, if the repository you're browsing on github has an open source license license.

Especially relevant nowadays given the trend to convert previously OS repos to non-OS licenses as a business model (eg Akka or Terraform.)

I've wanted to install an extension from outside addons.mozilla.org, but Firefox didn't let me do it

So I've did a small research and looks like there are 3 ways to sideload extensions, but all of them suck

1. Using FF Developer Edition

In the Dev Edition you can set xpinstall.signatures.required to false in about:config, but the problem is that the Dev Edition isn't as stable as standard FF

2. Temporarily load the extension

In about:debugging#/runtime/this-firefox you can temporarily sideload extensions, but they will be removed next time you open FF, which is annoying

3. Modify FF code

Lastly, I found this script which modifies the FF code, but this can break things so I don't want to use it

I'm really annoyed that Mozilla gets to decide which extensions I can install. So... what's the best way to sideload extensions?

Edit: thanks everyone, I'm now using a FF fork (Librewolf) which lets me sideload extensions after disabling xpinstall.signatures.required

Hi everyone, I'm excited to announce one more release before I take a short break. I have some other stuff starting up, so I won't be pushing out new features as fast, but I'll still be around to manage the project. (more at the end)

⭐ What's new in v1.2.5?

• Redirect posts to your home instance!: Post pages now have a redirect button that will find the same post on your home instance(1). You don't have to hunt it down yourself anymore.
• Posts related to this webpage buttons in popup & sidebar
  • Make a post: You can now create a post from any webpage! Click the 'Make a Post' button in the extension popup or sidebar to generate a draft post with autofilled title, URL, and body contents. Afterwards, just select a community and hit post. (This currently works for both Lemmy & Kbin, but custom frontends are untested while they develop). Try it here: https://lemmy.ca/post/4478560
  • Open Posts: This will find any posts about the webpage/article/video that you are looking at. Use it to see if something has already been posted, or to find related discussions about it. When there are multiple posts, it will ask before opening them all. (see note on risks and why it doesn't count automatically)
• Post an image: You can now right-click on an image, anywhere on the web, and hit "Post this image". It will open a new tab and autofill the title, image link, and add the page URL to the body as "Source: URL". Try it here: https://lemmy.ca/post/1282303
• Reorganizing popup:
  • I fixed the issue where the popup would still display a button after removing all instances from the list.
  • The number of default instances in the popup was reduced to 4
• Added settings:
  • You can now hide onboardining guides to make the interfaces less wordy
• General styling changes, wording improvements, and bugfixes

(1) This is an important feature to me because this little annoyance was part of why I set out to create the extension in the first place. Thanks to some help from @zero_gravitas, I was able to use the Lemmy API to grab the post details, and then run a search for it on your home instance. While most posts should only bring one result, there is a chance that there are multiple posts by the same user, in the same community, with the same title. If this is an issue, I'll make this search more specific.

🗣️ My questions for you:

Improving 'post to Lemmy'

• Right now the 'Post to Lemmy' button does a very basic search in the page meta tags for information. This works for most websites, but it is not perfect. What websites do you usually post from, and is the extension doing a good job of replicating how you format the post? Please share both good and bad examples, so we can fix what isn't working and keep what is.

Improving Post search

• Having the extension automatically count the number of posts and display it in the icon would be pretty nice, since then you would know about any posts for the news article / blog / video that you are looking at. However, there are privacy implications with this since it needs to send the URL to your home instance to do the search.
• I would like to add the option to whitelist specific websites, so the user can choose what browsing data they want to find posts for. Is this something you would list to use? What websites would you whitelist?

Anything else?

Please share any issues that you find. Lemmy and Kbin instances have a lot of variation in how things are structured, so there are bound to be some bugs that I haven't found yet. If you have any ideas for new features, please share them too! I'm always looking for new ideas to add to the project.

💛 Finally

Thank you for all the suggestions and feedback so far! I'm really happy to see that people are using the extension and finding it useful. I'm looking forward to seeing what we can do with it in the future.

Like I said above, I won't be as active over the next few months in terms of getting new features out. The extension is now in good shape, and it covers most of the important use cases. There's still lots of cool stuff we can do with it, so please contribute ideas and expertise! When I get a chance, I'll pop in and grab a few more issues.

Cheers :)

EDIT-2: The final solution was to add this to "My Filters":

@@||lemmy.fmhy.net^$3p

Based on Adblock Plus filters explained: Exception rules

EDIT: I went to the logger and found that EasyPrivacy filter list had a specific filter for ||fmhy.net^$3p:

This is the first time I see uBlock Origin blocking images from a random domain and I don't know how to whitelist them without disabling uBlock Origin for the whole site.

Any clues are welcome!
Thanks.

How's it with you guys ?

So the other day I was testing a new browser called waterfox. What stuck me as odd was how a small company seemed to have made Firefox so much more usable everyone. I normally use librewolf for privacy and security reasons but waterfox actually temped me to switch. (I ended up not switching for privacy and security reasons)

After I used waterfox for a bit I started thinking more and more about Mozilla the company. What are they even doing these days? It seems like they have stopped with the innovation. They could of setup a competitor to google with a custom nextcloud but they haven't made any competitive products other than a VPN.

I also saw a Nord VPN commercial and it was full of lies are usual (seriously, malware protection?). However a lot of there arguments could apply to Firefox. Why doesn't Mozilla do any sort of advertising? Admittedly Firefox isn't great in the UI department for the average user so it may be worthless
