What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

Firefox used to have my background colors, and on the latest update, my pull-down menu and tabs are robin's-egg blue. I can't figure out how to get my colors back, and I hate that color.

How the hell do I get back control over my colors?

Hi there. The Netflix homepage is no longer displayed properly. Only the headlines are visible without the thumbnails (see screenshot 1). Netflix is properly displayed in screenshot 2 which was taken in an other browser. Can somebody please help me to solve this problem. Many thanks.

I sent message below to Bluesky support and have tried all their suggestions (all relating to Firefox), but to no avail.

MacBook Pro OS 10.14.6. Yesterday (9Dec2025) I could open Bluesky & see my profile but could not add a new post. I then did an ‘age verification’ and received confirming emails. When pressing ‘New Post’ button just went to blank page. Under ‘notifications’ at the top, was a message “''''! r.countGraphemes is not a function''''”. I am accessing using ‘Firefox 115.31.0esr (64-bit)’. I have deleted caches, re-started ‘Firefox’ and re-signed into Bluesky, but problem persists.

Could you please advise how I can overcome this problem. Thank you, best regards.

Frequently when I hibernate my laptop firefox prevents its (as soon as it enters sleep it wakes up)

when I close firefox it hibernates fine

when I go to powercfg /REQUESTS its the audio card that is driving the wake up

In settings I have turned media.video-wakelock. to FALSE etc and firefox still wakes the computer

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

After the last Firefox update (146.0), my bookmarks bar only shows thumbnail images. The descriptive text which was previously black text on white back ground now appears to be white text on white background. (Whether my system is set to light theme or dark theme.) This happens on all of my Windows computers (both 10 and 11). How do I resolve this problem?

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

The subject says it all. The "tabs from other devices" are a) Shown as a long flat list of links, not in their individual tabs, which is disappointing b) right click does nothing - doesn't open them as advertised

I'm running FF on Windows v145.0.1 and navigate to...

...and the animation doesn't work. This is a recent phenomenon. I have another computer in the office I've turned off FF updates (obvious reasons) and the animation works fine. It worked on my computer until recently. I'm so exhausted with FF updates that break things, it's getting as bad as Windows. I've run FF in troubleshoot mode, no good. I've added this primary domain to exceptions to enhanced tracking, no good. Nothing works so I assume it's Firefox (may not be). But v129.0.2 works fine, in this respect (streaming the animation loops of GOES West).

Does anyone know what configuration or setting I can explore to make this work again?  :-(

Thanks,

If I go to the profile folder, exit firefox then copy and paste the folder to a backup location. The attempted backup fails. Something about permissions as I recall. I have tried many things unsuccessfully. Something has changed that does not allow for the backup of profile folders. Adding a backup option to the profile manager would be nice. I noticed some people have found work-arounds but I need a straight-forward procedure for backing up my folders. No work-arounds please, just a simple procedure. May I ask for help with this issue?

Could you add more sorting options to the bookmarks toolbar.

My preference of listening to music on youtube has been to add the songs as bookmarks and using the bookmarks toolbar.

For long i have been irritated i could not inverse the order of them, so when i tried to tweak with it for a bit i clicked the sort by name and quickly learned there is no other controls than that. This might be kinda niche but still applys to many types of usage and i feel is pretty basic. I would like the possibility of making the the bookmark toolbar to sort invertedly from date added. I strongly think this already should be a thing and was quite shocked to learn it was so archaic.

With respect, a dedicated firefox user desperate for salvation.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

When I turn on my Mac and click the Firefox browser icon, it will not load. It hangs. I get a "not responding" message and have to "force quit," again and again until FINALLY it loads, after five or more failed attempts. This does not happen with Firefox on my laptop, only my Mac. Both Firefox and my Mac are up to date. Why is this happening? Please help. It happens every day when I try to load the browser. I am about to give up and move to Safari. Relatedly, anyone know if it's possible to export all my bookmarks from Firefox to Safari?

I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?
