After latest update Firefox Developer Edition 151.0 Beta 4 I noticed much slower website loading while using few containers at the same time and overall more lag. Before the update everything was great and smooth I hope it's gonna get fixed soon.

I have a new desktop i7 computer with 16 GB of RAM. Why are my Firefox browser screens locking up? I'm running Windows 11 Pro. I don't have this problem with Chrome.

I am having trouble with Firefox that's very odd: the tabs keep overlapping and I am not able to click on links.

It keeps happening randomly and I have no idea why!

I've attached a screen grab so you can see what I mean.

When this happens I have to close down the tabs in question and then reopen them.

Never had this issue before.

Sporadically over the past year, a virus warning, purportedly from Apple, has locked my FireFox screen. I must Force Quit to unlock FoxFire. See images. Is this a scam?

I love Firefox and have used it forever. But its memory usage is killing me lately and I'm seriously reconsidering.... PC, Win11, Intel7, 16GB memory. (I'm typing this from Chrome)

I've updated, restarted, but it keeps maxing out and slowing my computer to a crawl. Somebody please tell me there's a fix pending?

I have used Firefox for years, but now it seems to be having problems with connectivity with both team meetings and zoom. Awful problems with meetings freezing or loss of connectivity.

Hi, when I use YouTube.com and i find this on "https://www.youtube.com/results?search_query=blue+connection+touch+the+sky" I get this popup message ""This page is slowing down Firefox",etc.etc. What happened to the browser? Thanks!

I have an issue where my firefox freezes whenever I try to take certain actions inside home assistants music assistant. I have created the following profiler of the issue https://share.firefox.dev/4pPZRPo

I have tried all the recommended settings to mitigate these kinds of problems (remove hardware acceleration, set disable all addons). I don't know where to report this exactly, but I'm hoping someone might be able to see something from the profiler that could illuminate what exactly is going wrong?

Notably this issue does not happen in firefox private mode.
