Hi

Since I updated Firefox my Twitch and Kick websites wont load the video. The chat work but video and sound wont start.

I tried it in chrome and there it works so something happend after the new update.

Google Sheets and Docs are not loading properly. They show their content while loading, and then go all black. I have attached an image. I added a link to the video, not sure if discord cdn will work though for embeds here.

The data is still there, just not visible.

I did see that older, similar issues were fixed with light mode, so I tried that. Same issue, but instead of going all black, it goes all white. Turning off extensions has not fixed this either. This has only been happening since the last firefox update; unsure if causal or coincidental. It also happens only on google services except drive itself.

I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

I replaced my default pdf application with PdfCraft but now, when I click on a pdf file, Firefox automatically opens two windows: one with Adobe and one with PdfCraft !?? Do I really need to uninstall Adobe to avoid this or is there a parameter somewhere to avoid this?

Folks,

Not sure if this extension is deprecated (last update was 6 years ago (Sep 17, 2020) 🤦🏽♂) but I wanted to know if this official extension is supposed to have sync support. Notepad is a simple little tool that is very valuable for its "basicness" (like stickies on mac, or note pads on windows). While the extension works locally, it seems not to be included in the suite of sync options currently offered under settings. At the moment, any notes taken on various computers using the same profile do not sync.

Thx all!

Since the last update with the light purple background my firefox keep on freeze. Please i want to go back to the version before August 2026. I still run win 10 and can't afford a new laptop at this moment. Please help.

The latest updates added a Firefox VPN toggle to the top of my screen. Now when I search on Firefox Google asks me to verify that II am not a robot. How to I remove the VPN I don't want? I do not want to verify I am not a robot just to search for holiday gifts.

I usually use rightclick+T to open new tab. And now sometimes it do a screenshot instead. Specially in some website that highlighting a link will popup an ui. So I want to disable this screenshot shortcut (but keep the open new tab shortcut).

Is there anyway to do it? Thank you!

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with crsorgi.gov.in. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails. Advanced What makes the site look dangerous?

Firefox is warning you about this site because the certificate provided for crsorgi.gov.in has been revoked and isn’t trusted anymore. What can you do about it?

Probably nothing, since it’s likely there’s a problem with the site itself. You can check with the website owner to see if they are working on the problem.

Hi, I'd like to remove the rounded corners ( they are too big) everywhere in the Firefox browser. The suggestions I've found online aren't helping me. Do you have a solution for beginners?

Hello again.

In 2023, when I had Firefox v110.0.1, an unfortunate hiccup caused my handful of windows and their many tabs to not appear when I restarted Firefox. I asked for help here and jscher2000 was lovely and walked me through some things to do, which are discussed in https://support.mozilla.org/en-US/questions/1408206 and https://support.mozilla.org/en-US/questions/1396868.

Unfortunately, though I now have Firefox v158.0, this happened again a few days ago and I've been trying to retrace his steps the best I can with the newer version, but to no avail, unfortunately, partly because I don't now see a sessionstore.jsonlz4 file that jscher2000 referenced back in 2023.

(As I remember it, a system upgrade was taking place on my PC, and, also, a new version of Firefox {the v158.0 I mentioned} was also being installed, too.)

I found a Profiles folder (C:\Users\Bram\AppData\Roaming\Mozilla\Firefox\Profiles\p9f543mv.Default User\) that seemed to be relevant, and found a sessionstore-backups subfolder there. However, while that subfolder did NOT have a sessionstore.jsonlz4 file, it DID have files named previous..., recovery..., and (possibly connected to one of those updates), an upgrade... file, too.

When I first found this subfolder (in that "Roaming" area...I looked also in the "Local" area but wasn't confident I found anything more relevant), I copied/renamed previous... (with a timestamp from around the time of that system update, and large filesize) to previousOLD..., and the MUCH smaller recovery... to recoveryOLD, similar to the instructions in those threads. However, even if I also copied that previous... file to sessionstore... (to match those earlier instructions), Firefox would launch but with only the most-recent tabs (i.e., the Advanced Preferences {about:config} tab along with about:support {to provide Troubleshooting Information}) showing, as I'd launched them as part of my efforts to restore the session, and nothing else.)

I have "healthily-sized" recovery... and upgrade... files with the same date/time-stamp and filesize, though my efforts to try to get Firefox to open correctly have removed a similarly-sized previous... from that folder unfortunately -- hopefully the fact that recovery... and that upgrade... file have similar sizes mean they might(?) be valid substitutes for previous... should one be needed.

I hope that this described my situation well, but am happy to answer any questions you might have about it to the best of my ability.

Clearly, Mozilla updated some Firefox characteristics in the intervening three (3) years but I'm not sure how to adapt the new set of filenames to those previous instructions although, as I wrote, maybe one of those larger files will end up being what Firefox uses to try to restore everything...I just don't know what to do with it (i.e., what to rename it and/or where to copy/paste it) in order to make that happen.

Can you please offer some advice in this regard?

Thank you very much, Bram Weiser

Xubuntu 24.04.5 Firefox 158

Firefox used to position a new window on the screen in a somewhat predictable manner prior to 158.

For example, if there was a blank space on the screen between other windows, the browser would locate it and be placed there. A new instance would also appear on the active screen (I have two: left and right with a single window manager spanning both) where the mouse was located. Now the window is just placed in some arbitrary locations and may appear on the non-active screen.

I have a number of scripts that load various sets of windows on the screen (typically a number of xfce4-terminals and the browser) which used to pretty much work, but no longer as the browser windows can show up any place and must then be relocated. When I start a new session I have eight distinct desktops with many versions of Firefox on each. It is tiresome to have to relocate one browser window after another.

Is there any option I can set that would revert to the older screen placement algorithm?

Also, I asked this before and don't remember getting any satisfactory response. Why is the -geometry flag not supported on Firefox any longer? What's the opposition to giving the user control over this? I want some command-line method for accurately setting the size (WxH) and position (X:Y) of the browser window on the screen. Am I missing something here?

Thanks for any pointers.

How can I write a review for a Add-on? I already tried selecting a star which is supposed to pull up a review window, but the stars are dead links/not active. I've attached the page of the Add-on that I'm trying to review. Thank you
