I started noticing that Firefox was giving me a lot of "not responding" freezes the past couple of weeks. The past couple of days I basically cannot access Firefox at all - constant, immediate freezing. I have tried uninstalling/reinstalling (multiple times), disabling hardware acceleration, running troubleshooter mode (still freezes! if it opens at all!), deleting profiles, restarting my computer, etc. I've done just about everything I can find online about this issue. Nothing has worked. I have no issues with Chrome or Edge.

Any suggestions??

When using the browser on the newest update on the android app, I am unable to interact with pop up menus, such as when I want to change the options of a search, and I can't give websites access to my camera because the allow pop up button doesn't work, the only thing I can do is tap off to the side of the menu to make it go away. The only fix to this I found was installing an older version of Firefox, ver 150.2 specifically.

I’m experiencing a strange issue on Firefox where a separate blank/dark window briefly appears over the browser while I’m browsing, then disappears.

The window appears to have the Firefox icon in the top-left and what looks like a Firefox tab/address-bar interface, but there is no visible text or error message.

It happens randomly while Firefox is open, including while watching YouTube. It does not appear when Firefox is closed.

Troubleshooting already performed:

  • Windows 11 cloud reinstall using Remove everything
  • New Microsoft account
  • Defender Offline scan clean
  • Multiple malware scanners clean
  • Malwarebytes Premium installed
  • uBlock Origin (only extension i use) removed/tested, but the issue remained

I took a picture showing the window appearing. Is this a known Firefox issue, background Firefox process, or something else?

Recently (past few weeks) I’ve found Firefox on my iPhone (iOS 26.5.2) has stopped loading. I’ll open the app and it won’t load the page at all. It also doesn’t let me reload the page, add tabs, or close tabs. Occasionally it will fix if I click a link from an SMS or something that then opens in the app. Quitting Firefox doesn’t work, restarting my phone also doesn’t work.

Hello there,

I realized that quite often when I restart Firefox (Developper Edition) and restore my previous session (latest occurence with 46 tabs), the window becomes invisible. It still exists, and I can even see it in the Window menu list pointing to my latest tab but it's nowhere on screen. I can add/navigate through/select/remove tabs using the keyboard, I can see them listed on screen when I Ctrl-Tab but the whole window remains invisible.

It'd be great if someone could help me out.

Best regards,

Emmanuel

I’ve noticed that Firefox gets noticeably slower the longer I leave it open. Pages that normally load quickly start taking several seconds, scrolling can become a little laggy, and sometimes a tab will just sit there before responding. Closing and reopening Firefox fixes it for a while, but the problem eventually comes back.

I’ve already tried clearing the cache and disabling a few extensions, but I still see the same thing. I usually have quite a few tabs open because of work and research.

Is there a setting or troubleshooting step I should check to figure out what is causing this?

Is my FireFox hacked?

I changed browser to Microsoft Edge. The problem went away.

Sometimes when I come back to the Firefox app (i.e. already opened to the last tab I browsed) the lower search bar is floating in a place on my screen higher than normal and I’m unable to access it. It’s blocking the screen and I can’t touch or type into the search bar. It requires a quitting of the app and restarting it. This happens almost every day at least once or more. Seems like a bug of some kind perhaps to with scrolling on the page. Would love a solution.

Ever since the latest update i've noticed my firefox browser after using it for a while starts eating up all the ram until my computer freezes and needs to restart, i've heard this issue happen to others too but i am wondering if there are any ways to prevent it or will there be any updates to fix it?

I use my firefox on bazzite and have nothing else running in the background, after a while i watch the stats in my task manager and i see firefox using over 10GB of ram and climbing and have to shut it down before it freezes my pc

(can't show any screenshots because if i do then my pc would probably crash when trying to SS it while it has its problem)
