Windows 2026-02 Preview Update (KB5077241) causes Acer laptop to crash when firefox opens when computer is started. Only on this laptop, other computers are unaffected. Firefox is the newest version and like mentioned, all other computers run the same security programs and vpn. The windows update needed to be uninstalled on the Acer laptop for it to operate correctly.

Using Facebook creates an "Isolated Web Content" which makes the page run slow then crash.

This has been happening for years, now and means I increasingly just don't use Firefox, switching to Chrome, instead.

This affects Facebook on my Mac (Sequoia) and PC (Windows 11) machines.

I have a problem trying to get the app PC Express past the sign in. The app is part of the yourindependentgrocer.ca app. I have used Firefox, Chrome and Edge and have encountered the same problem. I use Proton for my e-mail and I have used all their apps for my computer. I recently changed the start up app from judymk@protonmail.com to judymk@pm.me. I don't think this is a problem as Proton says the app should not care what protocol is used as it translates the same regardless of what app is used. I would appreciate any help with this.

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

I have reset Firefox as default browser on my Windows 11 PC a hundred times in the past few months. Today, I could not reset it at all -- I click the default button in Windows 11 and as soon as I close that settings window, it disconnects. I've run out of things to try to fix this. I think it MIGHT be related to Norton 360, because I first notice this problem when I opened Norton.

This is from Cabelas.com but I am getting it more and more from other web sites. American Airlines, Delta.com, etc. I accessed the help and did all the steps about fingerprinting and turning off "enhanced tracking protection" and nothing helps. Any ideas? Don't like the idea of using Chrome or Edge, but Firefox is almost unusable for me now. If I have to keep using another browser for the sites, may as well just use that one only.

I've always used firefox

Recently it seems to me that a lot of sites don't seem to recognise me, so I have to do multi step logins.

Paypal for instance. I don't save the password, I type it in each time, but now it insists on sending me an SMS in addition

My guess is that FF is deleting some cookies that I'd rather it didn't. What can I do?

Thanks

Youtube webpages won't load properly after saving. They start to load but then switch to a white page. I need to be able to save a video's webpage to save links and other information for later viewing. This started happening on any computer 2 or 3 months ago. I'm thinking that youtube did something that causes the saving of their webpages to be messed up. Youtube webpages display fine on youtube.com but saving their webpages doesn't work anymore.

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).
