Firefox Community Forum

I have version 156.0 (64 bit). It seems like the freezing started soon after the update and it is getting worse. Tonight it is only unfreezing for less than a minute. Some of the extensions showed that they needed permissions updated. Since I could not figure out what they did, I disabled them. None mentioned cursor control or issues that looked like they were nothing but options.

Hi,

I have been using firefox for a while now and realised there is this annoying performance issue tied to my laptop, where firefox keeps freezing randomly while switching tabs or scrolling. It doesn't seem to happen on my desktop pc, and browser such as edge and chrome doesn't have this issue on my laptop, so I am confused as to what is causing it and how I can fix it.

My laptop specs are as follow: GPU - RTX 2000 Pro and intel arc 140T RAM - 64 GB LPDDR5 CPU - Intel core ultra 7 265H

Hello, Might the "do not sell" signal (that firefox offer to send automatically to website) slow the browsing please ? I can't figure out if it is a whole request to send in addition or just few bit more in the initial one, or something else I don't have in mind. I'm currently struggling with lots of tabs slowing my computer, even paralyzing the mouse . I try to optimize as I need to keep my tabs, but I don't what is the best way to manage that. Are the tabs less expansive than using windows, for the memory ? Could the groups of tabs lighten the storage ? Is it better (and more usable! ) to bookmark or add to "the task bar" when we just need to keep the adress to use it later ? Actually, is there a doc already answering to that please ?

I hope you might understand my bad english and that sometimes, we can't find other way than keeping too many tabs.

Thank you, Erin

Hi Mozilla team,

I’d like to report a serious issue with Firefox lately. The browser has been performing very poorly and frequently becomes “Not Responding.” In many cases, websites fail to load properly or get stuck indefinitely, even though my internet connection is working normally.

I’m experiencing these issues on the latest version of Windows 11 with the latest version of Firefox. This has become quite frustrating and significantly affects my daily browsing experience.

I hope the Firefox team can investigate these stability and website-loading issues and provide a fix soon. Firefox used to be much more reliable, but recently the overall experience has been very disappointing.

Thank you.

Hi,

Whenever I try to upload any sort of file, the file explorer pop up thing opens, and then freezes. This doesn't happen with any other application, just Firefox, and it happens across websites. Eventually the window freezes long enough that you get the 'close/wait to respond option', and then it closes. Firefox itself doesn't freeze, just the file picker. Nothing ever crashes/closes unexpectedly, and there's no crash reports in the about:crashes thing.

It's not super urgent because you can copy and paste most files but it is frustrating. Any help would be very appreciated.

Thank you

Ever since a recent update, my animated wallpaper for Firefox only plays one frame, and then freezes. If i switch or refresh tabs sometimes it can trigger the GIF to start playing normally, but 90% of the time the background stays frozen, I don't think this issue is related to my PC because the wallpaper was working fine before the Firefox update, and I'm having the exact same issue on my laptop too.

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?

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?

When I login to Fidelity site, my username is displayed one letter at a time with noticeable delays. It started about 4 weeks ago. I noticed Remote Procedure Call was active with 4% CPU. I disabled remote access. The issue went away for 3 days, but has resumed today.

Is my FireFox hacked?

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

Hi, I am using Firefox For a few years, but for last 1 year my workload is high and I usually need to open several tabs. After I keep tabs open for a while, firefox becomes slow. Closing a few tabs help but I want to know what is causing it. IS there a way to check which tab or extension is causing it? I am using latest firefox on windows 11.

My Desktop - Win10, 260+ Gigs RAM/14+ TB HD space Firefox updated a couple of days ago, and again today (this time to 155.0.1) Ever since . . . . . . Having Major problems NOW No Rt-Clk function in Ff Ff menu buttons non-functional Ff tabs can no longer be rearranged Data entry fields, dropdowns, Submit buttons, & "add to cart" buttons not working on Ff pages -Things I've tried; I rebooted Ff & Windows several times each - No Joy I cleared Ff startup cache twice - No Joy HELP! I use Ffox for roughly 85% of my online activities - I'm pretty much hosed

PLEASE HELP!

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.
