Firefox Community Forum

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

when i sign on to my computer, frequently a prompt will appear that says i have to close the old firefox. sometimes i have to close it 5 or more times before i finally get connected to the internet. what can i do? im 83 and not tech savvy. also, when i sign on-the site crashes a lot and i should restart firefox and send a report in.

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.)

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 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

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?
