I have been using the Firefox Color extension for a while with no problems. I noticed that in the last few days, when I restart my computer, the theme resets. Specifically, when I first open Firefox, I very briefly see my saved theme but after just a second it reverts back to the default colors/theme.

When I go to the Firefox Color page, my theme is still saved and once I click on it, it takes effect until I restart the computer.

This only started in the last few days and I know there was a Firefox update (132) as well as a Windows update both in the last week or so.

I'm using Windows 10 Home, version 22H2, OS build 19045.5011.

Is anyone else having this problem or know what might be causing it?

Heads up for custom installs: running tbird and firefox on linux, I install both in my home directory for my own ease of updates and portability. I get releases from https://ftp.mozilla.org/pub/ in tarball formats which install in 30 seconds. I recently ran into a problem which I've not seen before. recent d/l of firefox-136.0.tar.xz for linux-x86_64. It crashed immediately with err 126. The ff.exe and ff.bin files were for ARM arch. This wasn't easy to locate and I think it was caught but anyone still headscratching may want to see if this is an issue - I had a good 136 on a laptop and overwrote bad install on desktop.

Windows 11 system; currently running 131.0.3 (64-bit).

Was offered the chance to update to 132.0 (About | Help) (I do not and will not ever allow automatic updates without user approval, and my profile is stored in an entirely separate folder structure well away from the insecure \users hierarchy). Did the usual click on the update button, showed 132.0 downloading, update button changed to "Restart to Update", clicked the button...

And the update failed. Help | About shows 131.0.3, and the "Restart to Update" button is still active.

Tried again with a full shutdown instead of using the update button, same result.

So how do I force this update to install?

I received a Mozilla Firefox (64) update notice going for version 132. When it didn't complete, I checked that my version is Firefox ESR115 (115.17.0), which operates with Windows 7-8.1. I have Windows 10, which matches with your version 132. So my question is how do I change/update my Firefox over to match up with Windows 10 and the Version 132 update?

I need to reclaim space on my hard drive so I was looking for apps to remove. I noticed that I have two installs of FIrefox. One is listed as "Mozilla Firefox (x64 en-US) (261MB) (2/7/2026)"; in the description area (when you expand the app panel) it says "135.0"; the "Modify" button is grayed out - all I can do is click "uninstall". The other install is listed as "Mozilla Firefox 72.0.2 (x64 en-US) (188MB) (2/23/2024)"; in its description area is lists the version again "72.0.2"; the "Modify" button for it is also grayed out - I can only uninstall.

How do I tell, from the Firefox that I launch from my taskbar or start menu, which one I'm running and which install I can remove?

I'm on a Windows 10 Lenovo Flex 3 laptop.

My extensions are not showing up in the firefox browser, on menu bar, tool bar, or bookmarks bar. I am elderly and NOT computer literate. What to do? Using Windows 10.

Thank you.

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

I'm trying to install ad blocks and it seems that the Firefox browser doesn't recognize itself as a Firefox browser. It's telling me to download Firefox when I'm using a Firefox browser in the first place

Hi, so i have a question: what are your plans to support windows 10 after 2025? How about windows 10 iot ltsc which is supported until 2032? Will firefox still be supported after 2025 on the iot ltsc version? Or will i have to switch to linux?

Like most people, the only reason I stick with this browser is for the ability to set it the way I want. Accepted the "upgrade" to 133 and it screwed my settings. Downgrading did not help. So fed up with this [redacted].

Hi! I m trying to uninstall firefox in windows 11. The "installed applications" of windows doesn t appear. Then, when using helper.exe does not allow to select "uninstall". Simply reinstall the application. Any suggestion? Thanks
