On PC:

1. Containers
2. Firefox's screenshot button. It's so good. https://i.imgur.com/9lHxekk.png
3. Wanting to not see the browser market be monopolized. Competition is good.

On Android:

1. Extensions support
2. This button: https://i.imgur.com/heuupxK.png It's so handy.

Been using it for 7-8 years and only seen it improve. A few gripes to deal with, but I'm happy otherwise.

Because not using Chrome or Edge is a must.

It's the most customizable, has the most advanced add ons system, syncs well between mobile and PC (though sadly with no tablet app), and it's not part of the Chrome hegemony. Lately it has become faster and faster!

It's the only browser made for users.

It's not chrome and it's open-source

Open source, private, not chrome. Because I've been using it for over a decade.

It's the least greasy browser that actually works with the modern web.

Desktop:

• damn nice
• good Flatpak version playing everything
• all extensions work without weird restrictions
• only Forks that make sense, Librewolf and Tor Browser
• loads of search engines
• arkenfox user.js
• UserChrome.css, in theory, if it was easy to create one. Only SimpleMenuWizard currently to make it less rediculous to use
• also Thunderbird uses Firefox ESR, and its the only good Mail program I know

Mobile

• mull, prehardened
• support for a looot of addons using a custom Addon collection
• offline translations using FF Translations, literally the only app I know that does this and its so damn critical
• dark mode without tracking
• ublock, noscript
• lots of search engines possible
• privacy

I dont use Firefox as it comes on any device, as this is unusable. But with hardening its simply the most secure browser

It's not Chrome, and it does everything I want.

I’ve used it on and off over the years; ever since 2004/2005 or so.

Firebug was amazing for web development back in the days when it was just IE, Firefox & Safari.

I recently built a couple of sites (for a sim racing community) and one of my users mentioned a Firefox bug. I fixed the issue but then realized I need to be more aware of Gecko specific rendering issues. I decided to use Firefox for a week on my iPhone (yes I know, still technically Safari) and my desktop, and I forgot how much I like it.

I also don’t love the choices Chrome has been making recently.

Firefox’s market share is so low lately when compared to Safari and Chrome that it honestly feels like the battle is already lost.

Because it's better in every way?

I just think it's neat.

My wife says: we use firefox

And i cant think of a reason not to.. so of course ive installed Librewolf

UBlock Origin

It was my first browser. I used IE to download it.

When I changed computers I did use Chrome for a bit. Then Vivaldi because it was better to me (I liked the split window browsing)

Saw mention that Chrome and all related browsers were about to kill adblockers. Returned home to Firefox immediately.

I don’t feel a need to change right now, but have heard of Waterfox and Librewolf as potential forks. They’re in my mind if I ever feel the need.

It's not Chrome. Are there really any other good options at this point?

Switched at the mere mention of losing my adblock. Have never looked back (besides when some shitty dev doesn't make their website compatible, looking at you comed)

Because fuck Chromium

Nothing based on Chrome is an option because Google is evil and thinks it can control my computer, Brave customer service literally made fun of me for not liking the way they took over my homepage regularly years ago, Opera is just adware, and Firefox is about all that's left. Even though it's losing more options every update and on mobile it's complete garbage now with everything centered around their homepage so they can try to serve me ads that I can luckily turn off for now.

Free Software for free people!

Addon support on Android, cross platform sync. I don't need any other reason

I've just been using it for as long as I can remember, so I guess brand loyalty is one reason. Also, I always get annoyed when I have to use another browser like Edge and Chromium. The last reason is that Mozilla actually advocates for an open web in the organization that develops Internet standards (as I understand it), so I would prefer to give them my tacit support, buy not using browsers from corporations that benefit from me as a users and go against open standards.

I use it since it's inception 20 years ago. And stuck with ever since. It was one of the first FOSS projects with a mass appeal. In Germany we even had a crowd funded ad campaign in 2004 in that I took part and all that felt very optimistic and cool. And I just always stuck with it and always used it as my main browser. When Chrome took over, Google was already the dystopic mega corp so I was never tempted to use it. Sure I installed it, but hardly ever used it. But I never had big problems regarding speed or resource-hunger. And it keeps improving.

TLDR I'm very nostalgic about FF and will never drop it.

I just started using it for Android the last month or so when Chrome dropped the flag feature that let you toggle dark mode for websites with system dark mode.

I have a VPN with an adblocker so that aspect of Chrome never bothered me so much. Chrome felt like it worked slightly smoother but at the end of the day a browser is a browser and Firefox does the job. (Samsung's browser is actually surpringly good for those with a Samsung device looking for a Chrome alternative)

Firefox does seem more trustworthy overall, although I've learned by now that trusting tech companies is not a sensible thing to do.

I tried Firefox but it was hot garbage on Android.

Ended up going with Kiwi - same extension support but just better designed and much faster. Firefox kinda sucks on mobile beyond ublock origin support.

Because best

Add-ons on mobile. Plus, Chrome is slowly but surely gimping their ad-blocking extensions.

because its not chromium

I switched to Firefox 2 from Internet Explorer 6. since then haven't used anything else.

gave some chances to other browsers like Chrome or Opera, but didn't like any of them.

as for why... no idea. Mozilla was always appealing to me and their browser is just on point everytime. and I also like red pandas.

I like it and I don't like google

Bottom tab bar, ublock origin.

Privacy and also fuck Google.

Why do you use Chrome?

I have been using Firefox ever since. Never really had a reason to switch to something else.

Container tabs, it respects my privacy, and brave started randomly not painting pages

Why not?

Web extension manifest v2 ublock origin

It was the only real place for NoScript for a while and I haven't found a better whitelist add-on. A lot of it is inertia at this point. I avoid Google as much as possible anyway, so Chrome isn't an option.

1. It's FOSS
2. Manifest v3
3. AdBlocking extensions for my mobile too!!!
4. They created Rust my all time favourite programming language.
