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'm not sure how long this has been happening (maybe at least a month), but my browsing history isn't syncing properly between my desktop and phone. Previously, my desktop history was syncing to my phone, but not vice-versa. Bookmarks, passwords and tabs are syncing perfectly fine. I've tried enabling/disabling sync settings and signing out and in again and now my phone history is syncing to my desktop, but my desktop history has stopped syncing to my phone. While having the full browsing history on my desktop is preferable, it would be ideal for it to show up on both my desktop and phone.

I have been able to use the builtin VPN for a couple of months now. In the past week, when I try to turn on the VPN, I receive a message that I am not connected to the internet, even though I already am.

What is the issue?

Since yesterday, videos on NetMirror are not playing. Every video shows a “Video load failed” error. I have tried multiple times, but the problem is still happening. Please help me fix this issue.

Setting up a new Macbook air m5 and trying to sync my profile/bookmarks/etc. on FireFox but the confirmation code is not arriving at my gmail. Checked spam and added "accounts@firefox.com" to my contacts but still not arriving. 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

Had my laptop serviced at Best Buy, but upon booting it up the icon for 1Password in the upper tool bar was missing. Trying to figure out how to add it back. I use Mozilla Firefox and have Windows 11.

This device is essentially a thumb drive made by MOPAR that contains automotive serve diagrams for a Jeep Wrangler. When you boot this device with Firefox being the primary browser you get garbage instead of schematic drawings. If I make Edge the primary browser the card boots properly and runs. This a legally obtained card with no password system on board.

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.
