I have noticed a weird scrolling bug in Firefox since either v138.0 or v138.0.1.

If you go to https://www.architecturaldesigns.com/ and select any floor plan, if you attempt to scroll down the page the page will not let you and snap back to the top.

I tried this in Firefox troubleshooting mode with all add-ons / themes disabled and encountered the same behavior. This is something that just started happening in the last version release or two.

This is present both on Windows as well as Mac versions of the Firefox browser.

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

I opened a new Firefox session (closed the previous one properly using the “Exit” option, without force-killing it) and had only 4 tabs open:

One YouTube video at 1080p One bookmaker site that may have a 240p video playing Two Flashscore tabs (static pages, no video)

When I end all firefox.exe processes, the Task Manager shows that about 10 GB of RAM is freed.

How can just four tabs be using that much memory? Please help me with this issue.

Thank you!

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

I tried all common troubleshooting steps: deleting cache reinstalling different settings turning off adblocker/vpn disabled efficiency in task manager and set it permanently to off in FF

I used to have 1000+ tabs in 2016 no issue. I had problem in past with Firefox using 100% CPU which now it is not using only like 50, but memory is getting full 89% i use also large page file on ssd. Problem is even when i restart firefox it is slow with low RAM usage! SO that's not it! Even 5 tabs sometimes it is slow!

It is so damn slow it drives me crazy! I tried also Quantum in past when Firefox has 100% CPU usage bug and it was only tiny bit better but still caused 100% CPU usage!

All other browsers are anti user cannot even stop Autoplay literal terrorist Firefox is only normal browser unfortunately performance compare to 2016 got absolutely abysmal! I had this problem even in-between reinstals of OS so it doesn't seem it is me. I play demanding games no issues on my PC...

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

Hello,

Hopefully this is something that can get answered quickly. These past few days I have not been able to use FireFox on my laptop.

It doesn't seem to be a wifi connection issue because other browsers work and other devices are connected just fine.

I also tried opening FireFox in the "troubleshoot" mode, but I am still receiving the same errors. I would appreciate any help I can get on this issue.

Below is a screenshot of the error I keep receiving.

Thanks,

What minimum memory spec is recommended for current Firefox usage? Have new computer with 16GB memory, 512 storage, intel core Ultra 5-225 processor & windows 11. Have not set it up yet.

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

Hello !

I recently got a new laptop (Lenovo Legion 5 I think) and while it's been working great, I've noticed a glitch that's happened a few times now. It's usually preceded by the image having some weird line pattern, I haven't been able to take a picture of it but it's almost like the pixels have been shifted ever so slightly. After that the screen sometimes splits strangely (see image). I don't know if this is a hardware problem or a Firefox thing but the only time it has happened was when I was on Firefox so yeah...

On my main desktop computer whenever I try to open a Channel page on YouTube, Firefox will start to lag and either tell me it is slowing down Firefox and I need to stop the tab or just crash.

Sometimes after I refresh a random number of times, it will load the videos tab and then be fine on that channel. On other occasions it will never load the channel's Home page or Videos page and I have to close the tab because it won't load or change.

This only happens on my desktop computer. It it more likely to happen if the page has a home screen video.

Let me know what you think. Thanks

I am trying to access iDRAC 7 on a Dell Poweredge R520. On version 133.0.3 I get a An error occurred during a connection to 192.168.1.20. PR_END_OF_FILE_ERROR. I know that the problem is that Firefox stop supporting older versions of TLS. So I choose to also install an older version of Firefox (43.0). On that version I get a The page you are trying to view cannot be shown because the authenticity of the received data could not be verified error. I used to have no problems accessing iDRAC 7. Has anyone else been able to resolve this problem?
