Firefox Community Forum

i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.

When my laptop is connect to a monitor via HDMI cable, the resolution on Firefox switches between what my laptop is at when not plugged in and the current monitor's resolution. It almost looks like Firefox is hiccuping between resolutions. This last for a few seconds and happens frequently within the hour. How can I stop Firefox from being confused about the resolution it's supposed to be at?

Do Mozilla really have no idea why their browser is considered a better alternative to other browsers? Why do they insist on making their browser WORSE for the sake of jumping on the latest stupid tech trend!? Some new tech that makes everything it's used in perform considerably worse? Oh boy sounds like the perfect thing for firefox! If this keeps up I'm looking into a browser that's at least more open about the fact it doesn't care.

Of 3 macs in the house, all on OS12, the one on ethernet to the ISP has been failing regularly: 1.) fails to collect history 2.) fails to present long-time home page 3.) if it does boot-up properly, expected behavior slows down markedly during a session on the computer (Usually rebooting the entire machine restores this. This morning even that didn't work.)

I have had a dual boot Windows 10/Ubuntu Linux set up for many years, with Firefox installations in the two operating systems both using the same profile accessible on a shared a disk partition. Since a Ubuntu update several months ago, using Firefox under Ubuntu produces the "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." problem when I revert to Windows and try to run Firefox under Windows. I can clear the problem by running a disk check in Windows on the shared partition, but does anyone know how to avoid this?

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

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

Hi!

I don't understand. Firefox is eating up memory again in the latest versions, and on top of that, it's the GPU on my PC.

4GB for the app and up to 8GB.

Are you mining Bitcoin on my machine?

What are you doing?

Whenever I try to use Firefox, tab keeps crashing and there is a crash report. It keeps happening to the point where I cannot work. Below are some of dozens of crashes I've had this week. I would genuinely appreciate your help.

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...

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?

When I use picture-in-picture for any video, all of my firefox browser windows go unresponsive. I can move the cursor around, but it won't allow me to click on anything. The only way to stop it is to open a brand new window which makes it responsive again and then close out of the PIP video. Sometimes it lets me go back to using the browser as normal, and other times it causes all firefox windows to crash. I'm using Windows 10. This issue only began happening about 10-ish days ago.

I have just installed Firefox on a new iMac, running MacOS 15.2. Firefox will not load any of the websites I have tried, whereas Safari and Chrome do. I have cleared the History and also set "No proxy" but loading still fails.
