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

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

I currently use firefox 133 (32 bit) on Windows 11. Every time my router resets (either due to power outage or xfinity server outage) firefox fails to connect to multiple websites after internet service resumes, for example, I cant get to twitter.com (x.com) or even the mozilla support page while on firefox. Screenshots of the error and associated stuff are in the attachments. Firefox currently can't even check for updates.

All the webpages that do not work firefox due to the issues highlighted in the screenshots load perfectly fine in other browsers like chrome and edge. These issues in firefox go away after a couple days without any intervention which I explains how I was able to use firefox for these webpages prior to my last network outage and have still not been able to solve this post network-outage issue.

Things I have tried so far: - Disabling proxy in firefox: Did not work so I re-enabled it since that is how it was before the issues happened. - Re-install firefox 133: Downloaded an installer from chrome to do this but this also did not fix the issue. Note that I first downloaded the mini installer which downloads files as part of the installation and that also failed to connect to mozilla. So I downloaded the full installer. - Cleared cookies and data: did not work - DNS over HTTPS: Swicthed it off, did it did not work, so I switched back to the default setting. - Logged in to the router from firefox using the router's IP address: Not sure why I thought this would work but it did not.

Any help would be appreciated to solve this issue once and for all.

Tabler Icons Stall Firefox on Windows

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

Machine: Dell Inspiron 15 CPU: Intel i5-7200U @ 2.5 GHz OS: Ubuntu 24.04 LTS RAM: 16 GB GPU: AMD Radeon R5 M445

Yesterday I switched on my PC, opened Firefox and the home page was black. See the attached screenshot. This is not caused by some accidental switching on of the dark mode. Dark mode is clearly off. Neither can I adjust settings to make the Google home page revert to its customary light grey shade.

This isn't a big deal, I know. And it has happened before and in a short period gone away by itself. Maybe it is to do with a glitch in the latest Firefox version. But it has an unpleasant appearance and discourages surfing.

My Chrome Google home page doesn't have this issue.

Can anyone advise on how to fix this unwanted black screen problem ?

I was on the ESR channel and after the recent updates to 142.01 or 141 the ESR is missing from the about Firefox. I had got the tab groups option a few updates back and liked it. This latest update changed how a tab group collapses, instead of showing only the tab group name and collapsing all the tabs it leaves one open wasting space when I have several other tabs open. At least I don't see any sign of the annoying AI junk getting in the way yet. I thought you had a choice to stay on the ESR channel according to this link and others. https://support.mozilla.org/en-US/kb/firefox-support-windows-10-end-support I'll probably be forced to update to Windows 11 to do my taxes next year but I thought at least I could stay on the ESR channel to avoid new features getting in the way.

Hi

Up to a few days ago I was able to see "View all memories" from One Drive in Firefox. Not anymore.

I am subscribed to One Drive. Every few days I get an email from One Drive with the past memories from the day of the email. I will open the emails and click on "View all memories" then it would take me to the One Drive and I would be able to see those pictures individually. For a few days now I have not been able to do this on Firefox anymore. The website goes to gray like it is trying to download the pictures but it gets stuck there.

This is happening both on my desktop with Windows 7 and my laptop with Window 11. Everything works in the Microsoft Edge browser. I can see all the images individually from that day.

I have communicated this problem to Microsoft One Drive and it seems to be a browser problem. Is there any way that this problem can be solved in the Firefox browser?

I would appreciate your help, Amy
