My PC crashed and then upon opening up firefox it forced me to update firefox. Afterwards all windows and tabs disappeared but my browing history is still there. I tried the in-browser restoration but it is greyed out. I tried the session store backup profile data but has no 'previous' or 'back up' files, only 'restore' files that are empty and restore to no tabs or windows. What other ways are possible? It's weird my browsing history anf bookmarks weren't deleted at the same time.

Hello:FF dev 156.0b3 sept 2026. w11p. Is there a simple way to reduce the number of items/cut back the list of items appearing in the context menu (R mouse button)? A 6-yr-old post on reddit says to use userchrome.css. This advice may no longer work? And the instructions seem a little confusing to me. Thank you.

I found a workaround (hopefully) for flickering black artifacts on 154.0 update in Windows 11

Hello

I have Firefox 154.0 on my 2 PCs that have Windows 11 and both computers are updated fully as of 22nd August 2026 with both Windows updates and Nvidia drivers.

Background: On my 2 PCs I have an "old" stationary PC with Geforce 1070 TI card, and I have a laptop Asus Vivobook 15 PRO with a Geforce GTX 4600 card. Both computers working fine and no issues so far.

Symptoms: I updated Firefox. Note! I always update Firefox on my computers, so it wasn't a clean install of the browser. And suddenly on both computers there were black artifacts all over screen and flickering when scrolling on Facebook or Youtube. Also even worse on sites were you drag a div and the browser turns into a 1-bit disco.

Workaround that seems to be working for me: I went to about:settings and searched for hardware on my laptop (the one with 4600 card) and searched for "hardware". Then I disabled the hardware acceleration thing, or whatever it was, but unchecking the result after search. Then I restarted my laptop not using hardware acceleration and it worked fine.

Then again I search about:settings for hardware and checked the bottom of the 2, not sure what the first one was. And restarted computer.

Now I don't have those black artifacts and flickering any more.

Not sure if that somehow triggered something that works for fresh installs or not.

Anyway... I can't submit a ticket since I can't reproduce the error it's no point submitting to Bugzilla. But hopefully this makes sense anyways... But I'm pretty sure you guys are aware of this issue already. But posting anyways in case it might help.

I received an error indicating that Firefox was unable to be updated. I tried refreshing the installation as suggested, to no avail. Then I removed the application, downloaded the most recent version, and tried to install it. The installation never seemed to begin. I tried troubleshooting compatibility again with no success.

I've rebooted between each failed attempt to install (at least twice). I opened Task Manager, and the process appears to be stalled. It starts; however, it doesn't consume any resources and hangs. I've attached a screenshot of basic system information.

I use Firefox as my default browser; I would really like to get the newest version installed on this device. Thank you, Aluca Lindstrom

Domain normalisation is corrupting

I am in the UK. I happen to have used amazon UK enough recently that it gets into the top-8 history in the address bar on a new tab.

And then the Amazon sponsorship – which is turned off in settings – corrupts it and "normalises" it to reference amazon.com. Screenshot attached with the misalignment highlighted.

Of what possible use is it to surface a top recently-used site when the address gets corrupted so it does not point to the site that has been used? This is idiotic.

Hint. When sponsored sites are turned off, respect that choice. Do not allow them to corrupt the experience. And even if it weren't a corruption introduced at Amazon's behest, domain normalisation is absurd when the site in question is geographically distinct. There is no possible excuse for it.

I believe that Firefox had a recent update which was auto implemented after-which my entire collection of saved passwords disappeared off of my Desktop computer. Over the next couple or more weeks I reconstructed many of the passwords and was heading back to normal. Today, for unknown reason my entire collection of saved passwords have again been erased and I do not know how and assume they are not recoverable so am back to square one. On my home computer I have it set to not allow auto updates and have a Firefox update waiting and hesitate to allow it, expecting the same result there to my saved passwords. Nothing significant has been done to or with my computer in this same time period so am at a loss as to why this happened not just once but now twice with cause unknown (I am unaware of any second Firefox update in the interim which could have caused this but cannot rule this out).

I keep getting: "Your connection may not be private Learn more. The page isn’t redirecting properly Firefox can’t connect to the server at auth.www.abebooks.com." I believe that I followed your instructions, but I'm not sure. I do not understand why "auth." appears in the Mozilla response when I do not type "www.auth.abebooks.com" but simply "www.abebooks.com." Thank you! Claude Gratton
