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??

My keyboard is stucking while searching on firefox , even after pressing enter it doesn't goes i had tried with floating keyboard it doesn't stucked, also tried with another keyboard and address bar at bottom it doesn't get worked, please solve this problem or i would shift to another browser

Hello! Since the latest update to Firefox (153, I believe) my Firefox has not worked. It starts up perfectly fine, but quickly freezes, becomes non-responsive, and needs to be closed. No matter how many times I attempt to open it, the same thing occurs. There’s been been occasions where it hasn’t frozen immediately so I have been able to turn off hardware acceleration as well as remove my theme and disable all my add-ons/extensions, but this has done nothing. Creating a new profile does not help, nor does trying Safe Mode: the same thing happens no matter what. I tried to reinstall the update, but this also did nothing. I haven’t yet tried to uninstall & reinstall or do a Firefox refresh as those are my last resorts and I won’t do them unless I’m sure they’ll make a difference. I haven’t downloaded any new extensions recently, and this only started happening after the most recent update. I’m not sure what else I can try at this point, and am very frustrated.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

When right clicking the context menu appears, but sometimes in odd places, and the disappears, so you can't select anything.

Same is true selecting the Help submenu from the Hamburger menu.

Restarting the browser fixes it for a few minutes, then same problem comes back.

Other people also reporting the same thing - also Linux Wayland: https://www.reddit.com/r/firefox/comments/1suounc/comment/oi7jk9u/

hi, I have this odd issue lately that when I type something in the browser, search engines in particular, then hit the enter key on the on screen keyboard, and then click inside the same inputfield again that the backspace button switches behavior and no longer affects the text field but deletes the last letter from the word in the auto-correct-suggestion panel diirectly above the keyboard. clicking back into the browsers textbox doesn't help either. I have to press backspace several times until auto-correct stops suggesting new words, (turning off auto suggest doesn't fix it) then focus returns to the inputfield in the browser

I can repro it with multiple keyboard apps (microsoft & heliboard), on different search engine websites but it only happens in Firefox not in chrome nor any other Android app.

I also noticed that when I move the text cursor somewhere with a tap in this input field and then hit backspace, then it will show the context menu (copy, paste, insert...) for less than a second and instantly close it again. Pressing backspace a second time doesn't trigger it again until you move the input cursor with a tap again.

I only use uBlock but disabling it didn't help. Phone: Nothing 3

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.

For the past month this browser has been really slow. I have cleared cache, deleted all history and its really slow. I'm using starlink for internet. any suggestions

I go to a website and it tells me that it has emailed me a code. I have to go to another app to bring up my email to get the code. When I go back to Firefox using the recent apps feature, on my phone, Firefox reloads to the previous page and I have to start all over again because you've gotten rid of the page I was on, to put the code in. It's an endless cycle. Since I'm not actually closing Firefox why can't it open onto the page I was just on?

Anyway to fix the issue?

WHAT ARE YOU SMOKING THESE DAYS?

Ever since I got the 150.0, the issue is the following: when I use the AI feature or search something on the internet, the first time everything is OK. If i would search something else or reply to the AI feature, the text appears to be doubled. In example

Hello its been a 2 or 3 months I have been using firefox and always have meet multiple malfunction on the browser, its not that I am saying its bad tho I like the GUI design and the features it have. But this recently update i experiences a malfunction that when I try to type a wrong word autocorrecting is kinda multi hopping like its scrabble some words I try to clear cache it and even clear cache my keyboard but still their. Hope mozilla find this bug immediately

Switching between private browsing mode to normal browsing mode or vice versa results I the header size increasing. Need to close it and reopen for it to go back to normal. Running Android 15 on an Asus Zenfone 10

This new issue is puzzling:

Normally, on MacOS, when you minimize an app that's currently running and occupying the desktop, say by clicking the orange button at top left or by clicking another app, its menu would disappear from the top toolbar and other apps could then be invoked. Clicking that app icon again would restore it to the screen and its menu would again be on the top toolbar.

But Firefox has stopped allowing that behavior: Now, when I try to minimize Firefox, while its screen minimizes (revealing the desktop underneath), its menu remains on the top toolbar. It is as if Firefox refuses to let go of the controls. So, while you can see the other icons on the desktop - say file folders - they are unresponsive to clicks and do not open when you click them, as if Firefox is not letting you access File Manager.

Furthermore, you can still access these desktop file folders, but only by opening the finder using the bottom toolbar menu, not by clicking the file icons directly.

For what it's worth, all menus are still responsive (bottom toolbar, top toolbar, apple menu), just nothing that's on the desktop responds when Firefox is still running, despite being minimized.
