Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

i have checked my mouse settings and reset everything but no change,,this started after a windows update, so i went in and uninstalled the update but did not fix the problem..i don't know how better to explain it, the scroll just stopped working while trying to scroll web pages,when i try to scroll the page doesn't move ., if i move my pointer over to the right side where the indicator of where you have scrolled to is and i click under it to scroll down and sometimes it kindof goes crazy and scrolls through many,many pages instantly...i hope all this some sense to you computer gurus cause i have tried everything that i know...thanks for giving it a shot..i use firefox browser and windows 11

I'll be on a page, maybe Facebook, the NYTimes, Amazon, or really any site, and suddenly I find I can no longer scroll, or otherwise navigate the page. I usually have to refresh the page, not so great an option, if I was in the middle of doing something, and and then it'll work OK. I shouldn't have to be doing that, and wonder why pages will just freeze up like this.

Whenever I have to restart my cpu, the menu bar appears to try to open all of the tabs and it causes system hangups and says that Mozilla Firefox is not responding. What causes this ??

Lately, after last firefox update, whenever I start Firefox, it loads normally but when I click to open a website it freezes with a not responding message. I have waited for 10 minutes before and never responds. Even opening in troubleshooting mode it won't respond.

For the past few days, the text in the address bar can no longer be selected or edited using the mouse or keyboard. The “Customize Toolbar” option does not allow you to remove the address bar from the toolbar.

Unfortunately, compatibility mode doesn't help here either. The problem isn't caused by a plugin.

Is there any way to fix this without losing all my Firefox settings and add-ons? I'm hesitant to try repairing Firefox.

The complete page I'm looking at, blurs when my desk top page changes. When I mouse over the page the blur clears up just under my mouse. Now you might want to focus on desktop but changing taps also cause a blur. When I say blur i am talking the hole page. I'm using Arial and have ran clear text on both monitors it all so seem worst when I used the new side tab load. Never had an issue on older fox loads.

Firefox hangs when Thunderbird is open. At this moment, Thunderbird is not open and Firefox is hanging on opening any web page. I had to use Chrome to get to this site and request help. Here is info about my PC:

I have noticed for some time when I access Facebook the site reacts very slowly and hangs up frequently. When I access Facebook on the Chrome browser I don't experience the same problems. So, it appears my Facebook issue is a Firefox browser issue. Can anyone please help and explain how I can improve my Facebook experience while using Firefox. Appreciate any help. Thank you.

After updating to Firefox 153.0.1 on my 2026 MacBook Pro Silicon running Tahoe 26.5.2, my Firefox sidebar refuses to open, either by toggling the menu bookmark sidebar icon or pressing the shortcut keys.

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.
