In recent weeks, on both machines, Firefox occasionally disappears, about half a dozen times in total, and when I restart Firefox the window I had been using doesn't come back. The History tab has no trace of the lost window, nor of any of the tabs it had contained. It takes me a long time to try to "reconstruct" the lost window and tabs from memory, and I'm only ever partially successful. So these incidents are extremely annoying.

I use Avast software to protect my computers, and I tried to blame Avast for the above happening, but they denied being responsible. I allowed them to remote access my desktop PC, and they said that they could detect nothing wrong.

The problem has happened again this morning on my desktop PC, hence this report.

The two computers are not linked in any way other than accessing the internet via the same cable out of the house, so I don't think that some kind of "cross-infection" could have caused Firefox on both to become unreliable. Of course, both machines automatically update their versions of Firefox and Windows 10.

Phantom tabs that exist but are only selectable in sidebar addons for vertical tabs

Video: https://www.youtube.com/watch?v=dJHFBAIHlwI

I’m switching tabs with either: • Ctrl+PgUp • Ctrl+PgDown • Ctrl+Tab • Ctrl+Shift+Tab These skip over tabs that appear in every sidebar vertical addon’s list, but stay hidden from the native tab bar. I don’t recall closing them, but perhaps I did at some point, still, why do they get stuck? • I can select them by clicking so they exist • Sidebery’s active tab style gets applied on all of them • Native tab bar shows no active tab • Normally I hide the native tabs but wanted to see how they match • The tabs are there with the inspector (Browser Toolbox) • Issue happens all the time with a few tabs

Addition: When I tinker with these broken tabs using the inspector they seem to collapse and get closed. They are no longer selectable and if I switch sidebar addon (and back) they are no longer there.

I normally don't use multiple vertical tab bar addons, they are just there to demonstrate the problem. It happens with a single Sidebery as well. In FF settings container tabs I removed the preset containers. This mismatch makes the browser unusable for me. I require working vertical tabs (I come from Vivaldi, wanting to switch).

Dear support team,

at one of our own web pages the encryption certificate was outdated, so I get the message Warning: potential safety risk detected.

More information... => I select Advanced

Error code: SEC_ERROR_UNKNOWN_ISSUER

I select Accept Risk and continue


It's ok, that the certificate is accepted temporarily and the web page is loaded.

It's not ok, that a permanent Certificate Exception is added without any information to the user. I know, that in former versions it was possible to select, whether this exception shall be permanent or temporarily. Could you pls. add this selection?

Windows 10: Alt-tabbing sometimes causes Firefox to freeze momentarily

As far as I can tell, this has something to do with Firefox aggressively offloading stuff from memory to storage. When I alt-tab at times, Firefox completely freezes. Every Firefox window hangs on a single image and I am unable to interact with anything for a few seconds. During these seconds, I can see the memory % in the Windows Task Manager slowly climbing until Firefox unfreezes itself, so it seems to be loading stuff back into memory. For example, it'll climb from 55% to 70%, taking its sweet sweet time. I also see some disk usage with 'System' during this time.

This behavior occurs even when I'm active on the browser and at 50% memory. It seems to occur more often once I hit the 60% memory mark.

I'm almost certain that this is a Firefox-specific issue, because I can interact with any other program during this period. It is only Firefox that stops dead in its track.

Is there a way to make this behavior less aggressive? I'd rather not have my alt-tabs freeze every few minutes.

It's kind of hard to describe aside from the title.

Only happens when I am using the drop down bookmarks toolbar. When I right-click on an item to bring up the menu, it flickers for an instant, then hides behind the bookmarks drop down menu. Ok, so I guess I could explain it a bit more.

But here's a video showing it more in detail. https://www.loom.com/share/a166451f9354463dbbb6d9faf57df315

I was trying to use the Private Mode with all the extensions disabled to see if that would solve the issue, but alas, it didn't help me isolate anything.

I updated my Firefox today and now videos do not play.

I had this problem back in April after an update and I spent weeks troubleshooting it. Eventually I got it to work after trying all of the following (then, and again now):

Things I've Tried: 1.) Clearing data (cache and cookies) 2.) Turning off "Strict Mode" 3.) Running CCleaner 4.) Disabling/enabling HW acceleration 5.) Checking that the DRM box is checked (and trying it without it checked) 6.) Refreshing Firefox 7.) Uninstalling/Reinstalling 8.) Updating my Windows install 9.) Updating drivers 10.) Disabling all Firefox extensions 11.) Running without extensions 12.) Running in Firefox Troubleshooting Mode 13.) Running Windows in Safe Mode with Networking 14.) Running a fresh install of Firefox without signing in after deleting all traces of Firefox from my PC (including Program Data folders, registry entries, etc.)

What finally worked back in April was to dive into "about:config" and change "media.rdd-processenable" to "false".

That fix does not work this time around.

In the meantime I've been using Brave and having no issues. I've tried video playback in Chrome, Opera, and Edge on this computer with no issues. This playback problem is exclusive to Firefox.

Video playback still works just fine on my 4 home PCs running Windows 10 and Pop_OS (3 self-built, one Asus laptop) using this same build of Firefox.

Other/Rant: I suspect this is a Firefox/Windows 11 problem. Most likely this is not something I can fix myself, but it's incredibly frustrating since I'm buried deep in the Mozilla ecosystem and use it for work. I'd prefer not to have to swap between browsers just so I can watch videos; too many windows open on this tiny work laptop isn't fun to juggle. Basic video playback is the #1 thing I use my web browser for at both work and home so it'd be nice if this irritating, months-long, unacceptable issue were resolved. A modern browser that has video playback issues? What good is it then? What's most irritating is that it seems I'm the one of a very small number of users with this issue, since I see very little posted about it online.

I've been a Firefox user primarily for almost half a decade now - moved over from Chrome for privacy issues. Never had a problem until 4/22 of this year and considering it's still an issue 3 months later... it has me re-evaluating the reliability and my commitment to an otherwise amazing browser.
