To preface:

On the website https://danbooru.donmai.us ever since I ran the firefox profiler for a different issue (I don't think it's related atm, just coincidental) I have been having a serious issue with loading images on all browsers. I've been trying to see if I can figure out the actual cause through firefox to no avail.

What occurs: If I open up an image in another tab, and the image does not finish loading, If I try to open up any other images, or go to the next page of a search, all danbooru sites will hang until the image finisher. This seems to degrade until eventually one will stop loading.

A few times, I've been able to catch this error:

Secure Connection Failed

An error occurred during a connection to danbooru.donmai.us.

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.

This seems to apply to any image aggregation sites where I can load an image large enough to require loading, as if the image loads instantly, nothing occurs.

What i've been ultimately trying to do is figure out why it's happening. My closest route so far has been that it's in some way related to the TLS handshake, the problem is I can't find anything in the console, network, or debugging that points to the when the image was loaded.

I'm currently running the multiprocess browser console as well, and while it's had a lot of things pop up, none of them refer to the final website of the image, or the script number that shows below it in the src.

So ultimately, I guess what i'm asking:

1. Do you know what would cause websites in the same domain to hang until one finishes loading?

2. What in firefox can see the loading process?

Lastly:

-I have already re-sync'd the system clock

-I have already reset the firefox profile, with a complete deletion and reinstall even

-I tried turning on webGPU, I don't think it's done anything

-I have not tried messing with the TLS settings because apparently SSL 3.0, 1.0, and 1.1 are supposed to be off

-I have done numerous DNS tests including a namespace benchmark test to try to make sure the DNS is okay, and did NS lookup to make sure it was actually being used

-I have used curl to download an image during the hanging, and curl was able to download before the browser completed the process.

-While extensions are active at the moment, the error originally occurred while I was running the firefox profiler for several days in test mode. Meaning it was also occurring for several days while no extensions were active.

-The hanging is isolated to the domain that it's occurring on. I can go to other sites while this is going on. Youtube can run during it, and I can load images elsewhere. A speedtest runs at full speed with no ping or latency.

This isn't entirely related to firefox, as i'm fairly certain other browsers are doing it as well atm, though I am interested in knowing if there's any ways within firefox that I can troubleshoot this.

And yes, trying to google this mostly just brings me to programming sites and nothing on the basic user level.

To preface, I have had a thread about this previously,

https://kbin.social/m/firefox@lemmy.ml/t/840667/How-can-you-troubleshoot-a-crash-from-freezing

Ultimately, it didn't result in much.

Cue a few months, a lot has happened, and I have a new PC. Different graphics card vendor, different RAM, different motherboard vendor. Almost everything is different.

The crashes stopped, in fact I didn't notice them for a long time.

Past few days however, I noticed youtube videos starting to skip a bit. Thought it might just be youtube.

Then today happened. After about a month, I had a crash again. The PC has been left on for about a week (which is not really uncommon for me).

What I noticed that caught my eye...is that when i went to close it in task manager, it was using 14 GB. Just to be fair, I made sure before completing this post that I kicked every tab I had open out of inactive.

They are currently sitting at 5 GB.

What is occurring that is causing Firefox, under the same amount of active tabs (in fact possibly more, since I do have auto tab discard, so most of these tabs would not usually be active) to reach 3x the amount of ram they actually use?

I would like to get it to stop crashing, but it seems like even under a different hardware configuration, all I've done is make it take longer for it to actually happen, which makes me think even more that the it's an issue with memory.

I've been having inconsistent crashes for awhile now where the screen will just suddenly freeze and go white, requiring a close/reopen. It's not usually an issue as it's not too frequent, but it's frustrating to have a bunch of tabs waiting to be reopened.

My issue is that I've tried to check google on how to even look up what might be causing it, and it has been very uncooperative.

first: about:crashes. It's empty. I tried to see if there's a way to turn it on. Any links I could find seemed to be outdated as they pointed to about:preferences#advanced. Which isn't present.

second: checked C:\Users\(username)\AppData\Roaming\Mozilla\Firefox\Profiles\(user profile)

First I checked to see if there was just a general log, then I tried to check crashes.

in both places I tried checking, the file was in a mozlz4 format. I am unsure how it is meant to be read. It was also concerning that despite finding a crash file that matched the time of the crash, all it had was a single meaningless line

"mozLz40 8 ô{"v":1,"crashes":{},"countsByDay ð
rruptDate":null}"

I'm assuming it's not meant to be opened in notepad, but the files I saw in datareporting seemed to be much more comprehensive than this.

So what I'm basically wanting to know is: How do you find out the last thing Mozilla tried to do before freezing? I can't determine if it was Mozilla or an extension doing it, and if it was an extension I can't determine which one.

The main issue is that the crash is inconsistent and mostly randomly. Even if I turn off extensions it could take hours to days before anything happens.
