Random tabs never load ("rotten" FF sub-processes?)

First I need to point out I'm very difficult user for FF :) Right now I have 52 windows and 476 tabs open

This not a hardware problem as I have good CPU (Ryzen 5 3600) and 64 gigs of memory - running FF 80.0.1 x64 on Windows 10 19041 x64

Until recently everything was fine - I'm not able to tell when that changed but it's just few days

When I start FF, some tabs (from "restore" session) never load. Tab just shows its loading but never finishes. Moreover if I try to open new tabs, they RANDOMLY also never load - doesn't matter which site/page (in other browser same url opens instantly). I need to open X new tabs, paste URL and hit enter into each and after a while the Xth tab loads instantly. X is changing - with freshly started browser its something like 2-4 new tabs. Later it can be 10 or more until "I find" the tab which loads. When I do that, i can open Dev Tools before pasting URL - Networking tab shows no requests, nothing. Same with right-clicking links in working tabs (open link in new tab).

Working tabs are usually good - left clicking links or F5 works fine. But if the tab is left open for some time without activity, it can also stop working (F5 doesn't help)

What i tried: - disable my Firewall (Kaspersky) - restart FF in safe mode without plugins - no "clear cache and cookies" as its not related to any specific site or page

I got the idea recently that maybe there is some problem with FF processes "rotting" (multi process architecture) so I'v tried to kill some of the sub-processes in Task Manager. Of course its hard to find the right one but I'v managed multiple times to hit the right process and suddenly all "loading forever" tabs showed as "crashed" and when I hit "Restart all crashed", all loaded instantly

Any help appriciated! Thanks!

How is this possible - PC is running normal now. I was not doing any resets or something like that. Thanks for helping

I have kept FF v. 56.0.2 because of certain add-ons that I have come to rely upon. That version is shared by all users. However, I would like to add the newest version for a second user. How can I install the current version for only the second user without affecting v 56.0.2 for the primary user?

Hi, my firefox doesn't seem to want to launch from the start menu for some reason (when I click it the start menu closes but Firefox does not open and isn't running in the background), however the shortcut that is created on the desktop seems to launch firefox perfectly well. However, when I do open firefox, it has a blank default icon as if its a random program. Could someone help me? This issue is getting quite annoying and tedious and I've had to switch to edge for a while now. I've been using Firefox about a year now and this hasn't happened before.

Steps I've taken:

  • Uninstalled and reinstalled firefox, deleted profile data too
  • Restarted PC

Here is a screenshot of what my icon in the taskbar looks like: https://i.imgur.com/d8uAq8a.png

Any insight from anyone?

I am a university professor. All of my classes use Canvas software. After last week's Firefox update, none of the embedded figures on my course pages appear - only their file name. They are showing up just fine in Chrome, so I know that the problem is somehow connected to Firefox. They also disappeared immediately after the last update.

My students and I need to be able to see the images...and I don't want to uses Chrome. I would like to know how to either return Firefox to its previous version or have the new version somehow corrected so that it gets along with Canvas.

Thank you.

When going to site using saved login message " View all saved Logins " can be seen. If sombody else is using the system other than myself this will allow all login and password to be viewed for all sites. Other person could be wife or hacker or other. I cannot see that my system is secure when using Firefox. For me to be able to view all logins is a bonus but should NOT be available to just anyone who may use the system. Any comment please?

I have a website which makes ajax requests to some endpoints which can take more than a minute (depending on how busy the server might be). In the recent version of firefox (81), it seems like after about a minute, the request appears to time out without an error message. I checked against other browsers and none seem to have the same issue.

Was this behavior expected out of version 81? I don't see anything in the release notes about this kind of change.

I have a custom add-on that I'm working on for my team. It's hosted internally on a server signed by our company's internal CA. The add-on is signed by Mozilla, but not hosted on AMO.

I am on the latest version of Fedora running Firefox 81.0. In the browser console I get this error relating to the URL for the addon when I tell Firefox to check for updates: "Certificate issuer is not built-in".

I have the company CA installed and when I navigate to the site in the browser, Firefox recognizes the cert. I've done some reading on the subject and seen several threads about it. I've tried a few things already, but most of the threads where a couple of years old.

I'm asking the question here hoping to figure out what the current state of the problem is and which settings I should tweak to have it trust the company CA or what my options are.

Thank you in advance for any support on the issue.

I am using tab-on-bottom code in userChrome.css that I got from the web.

1. There is a highlight feature of the tabs. A mouse-over will do a subtle enhancement of the top portion of the line delineating of the tab. 2. The active tab has a blue bar at the top portion of the line delineating the tab.

I want both to go away. I have code to highlight the background color of the active tab and need no other highlight function.

The userChrome.css is below.
