Firefox crashes whenever my computer goes to sleep. I am running windows 11 and have been for years. This problem showed up a few months ago. The crash then screws up other apps and I have to restart my computer to fix it.

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor. Regards, Guy James

When I try to log into Tangerine bank I get the error. "We're sorry for the inconvenience. This function is currently unavailable. Please try again later."

This issue started Oct-13-2025 and it appears to work when using Firefox ESR 146.01 but not the regular Firefox 146.01 versions. Tangerine is not giving me information on the error and I was wondering if there is a difference between the ESR and regular version that might clear up this issue?

I'm unable to print Yahoo emails via Firefox 146.0.1. I receive a 403 forbidden error. Listed below is the error:

Looks like there’s a problem with this site https://mail.yahoo.com/print/message/AAHdMRfbvQcEeFDcuycB940Whp3? appName=NOVATION_APP sent back an error. Error code: 403 Forbidden • Check to make sure you’ve typed the website address correctly.

Just FYI, I can go into the Chrome browser and print without issue.

Every time I close and reopen the browser (and then check the Process Manager), all my pinned tabs are there and taking 20-30 megabytes each while I didn't click on them and they're supposed to be unloaded after startup

None of the unpinned tabs are in the Process Manager

How do i stop this?

I have a pop up that is coming through probably 50 times a day that I can not figure out how to get rid of, can someone help me? ITs a little notification the comes through in the top corner of my screen and its driving me nuts.

Amazon pages don't load on Firefox 146.0.1 (64 bit). I'm using a Windows 11 Desktop PC. I cleared the cache but still have the problem. Please advise. I've used Firefox as my primary browser for decades but if this issue is not resolved, I may be forced to switch to a new primary browser. Anthony

I've been extensively relying on the `Ctrl+Alt+X` shortcut to spin up the selected chatbot in the sidebar, but ever since I reset my pc (complete reset, cloud download of windows, clear all apps and files) and re-installed firefox, the keyboard shortcut isn't working for me anymore.

I installed firefox with chocolatey, upon noticing that the shortcut had stopped working, I tried to downgrade to v145, which didn't help either. So an uninstall and re-install later (this time manually downloading the installer exe), `Ctrl+Alt+X` still doesn't work. Although hovering over the chatbot's icon in the sidebar shows the shortcut in the tooltip.

More info: `choco uninstall firefox` created a backup of "Old Firefox Data" or something similar, could that have somehow persisted the malfunction across installs?

Any help would be appreciated! System: Windows 10 Pro Firefox: 146

My selected topic "settings" actually does not really describe my tabs problem. Even though I followed instructions for entering "about:unloads" the expected webpage did not appear. All I got was the same instructions and not a page that included the table and its unload button that was said to be above it. When I select the New Page tab and right click and then select three tabs, the right-click menu only shows the option to "close three tabs." There is not an option to unload three tabs. Yikes! And when I select one tab and click on the one option to unload one tab, the selected tab does not unload. The tab does not unload. The tab does not unload. It is still there. (???) This is very frustrating! I can only close tabs. So far I can only temporarily close them. Could the problem be that I am still using Windows 10? Please advise. Thanks for reading about my problem of not being able to unload my unwanted tabs.

I created multiple profiles with the new [management] feature. Amazing, I've been waiting for it for years!

If I open all my profiles I can distinguish them since they all have a different icon. I can also pin all the profiles (Keep in Dock) to the MacOS dock.

When I quit all Firefox instances, I would like to be able to immediately jump back to the desired profile.

Instead I get multiple Firefox icons (without the icon profile, that disappear after I quit Firefox). I find this inconvenient.

Hi,

I am trying to use the website Jpay to connect with a loved one in prison. When accessing jpay's website I am prompted to enter my username and password in order to access the account. I enter the correct information- select login and the page will attempt to load and redirect me to the next page, but unfortunately nothing happens. The page will flash and prompt me to enter the username and password again. I am able to login into my Jpay account using safari, edge, and chrome however those browsers are no longer compatible with the jpay server for video visits. To add- I have purposely input incorrect details and when the page redirects it advises that I have input the incorrect username and password. Lastly, I have tried using several devices that range from a laptop, two different iphone, an ipad and an android tablet, the issue remains the same firefox will not redirect beyond the login screen. I have contacted jpay directly and there is nothing they can do. Please provide any advice on how to fix this issue. It appears to be on the back end. I have attached two snips. One showing i entered my information and clicked login. The next shows my username and password has disappeared after the failed load/ redirect. Thanks!

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?
