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!!!

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.

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

Hello, After the last update i keep seeing a blank page when i open a new tab or new page. i tried the troubleshooting mode but the same. i need to refresh every time i open a new page.

Anyway to fix the issue?

For the last four days every time I go to clear my history,"Program not responding" with a white a line at the top of the page with a message to close program or wait for response. I have tried restarting my computer with no change. If I close the program and restart I don't see a change. It seems to be intermittent. Please find out what is causing this glitch .

Thank you.

WHAT ARE YOU SMOKING THESE DAYS?

Hi

I have notice when there are multiple tabs open and multiple extension running the app seem to lag with page reloading ( youtube, google, insta)

Also PIP for youtube is broken with maybe hyperos 3 Youtube controller or browser customize controller for youtube

Kindly check that

I have realised if browser is optimized well then it can replace many social media app with more privacy and customization

I have a problem: when I open any Instagram reels link like from google , facebook , forum , etc https://www.instagram.com/reels/****/ the browser freezes. After a bit, a “stop” message shows up. When I click it, it opens a blank page like the one in the screenshots, and the tab completely freezes — I can’t go back, forward, or even close it. Even if I close the browser, it keeps running in the background. There are no extensions enabled (I’m using troubleshoot mode). windows 10 64

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/

On a new laptop with Win11 Home (x86-64) with Firefox just installed, the cache size is 54 MB. When Privacy and Security -> Clear Browsing Data is clicked, Firefox hangs - no input is accepted and nothing appears to be happening. On closing Firefox and then reopening the cache size is reduced and Clear Browsing Data operates as expected.

Why is the cache size (54 MB) so large? Why does Clear Browsing Data hang Firefox?

For at least a few months now, my browser will suddenly and randomly go fullscreen all by itself. I can't exit it, and then it goes back to normal after at most a minute. It hasn't happened in at least a week. But today, it froze like that, not responding. I quit firefox, waited a bit, then restarted it. It went fullscreen and froze again. I waited at least 10min and it then went back to normal and responded again. It only happens when using firefox. I've done virus scans, etc, and it still keeps happening. Please help. Thanks.

I have tried safe mode. No joy, but it has shown plain vanilla FF is the issue, not extensions.

(I'm using a different browser to make this report, so Share Data button is of no use here.)

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

fonts.googleapis.com is locking up websites for 40 to 60 seconds per keystroke. I have researched this problem and tried everything suggested, but nothing works. Much of the solutions include changing the settings used on menus which no longer exist. accounts.google.com is doing the same thing. This is driving me nuts. Help!!! Latest version of Firefox. Windows 11 desktop computer.
