Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox

I ran the windows 11 system file checker (sfc/scannow) to fix a font problem I was having. It did say that problems were found and fixed and I do not seem to have that problem any more. After that, i could not access the Settings in Firefox. I uninstalled and reinstalled Firefox and still could not access Settings. I also cannot access any Web sites either by typing them into the address bar or using bookmarks. Both Chrome and MS Edge work.

I watch Rakuten Viki, and suddenly a recapcha box is popping up on the bottom right, blocking the full screen button.... so annoying,,,, how can i get rid of it/ THANKS

I just got a new Epson 3-in-one printer and tried to sign up for the warranty. I got a message that the warranty was expired... I went to the Epson support site on Firefox and Malwarebytes blocked the site as malware... It said I could add the site as approved, but I don't know how to do that. "https://www.epsoncom.com/my-account/home". The Epson site said I already had an account but my password was incorrect. I had an Epson printer more than ten years ago; I don't remember the password and they don't provide an option to reset it. HELP, PLEASE.

The comment sections for foxnews.com and other sites disappeared using Firefox but not when I switched to Chrome. This just happened 6-18-25. Before this date, it worked on Firefox.

Using Firefox, my gmail inbox is my home page - and has been for several years. As of yesterday, the page opens but the page is blank. I am not aware of any changes that I have made.

I do not have this problem using chrome on the same device or firefox on other devices.

Probably something simple, but I have no idea what.

Thank you

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

Hi, after the recent update i am not able to click on the File menu on extreme top left corner, i think it is due to the rounded corners of the selection box, the corner pixels are inactive when hovering over. This makes clicking harder, before i could click it blindly by moving the mouse to the top teft corner fast, now i have to aim it, please fix this.

I am looking for a way to adjust the settings, or really anything else, in a way that would result in the site being displayed like it should be because it is a rather integral part of the game and I really don't know where else to look anymore. Now, I suspect that it's because I switched to Ubuntu because I've never had this issue with Firefox while I still used Windows, but I really hope there's a way to resolve this. That being said, it seems to be specific to Firefox for Ubuntu because the colors show up in the menu when I use Opera on the same OS.

The four images I've added should show what I'm talking about (I really don't have a way to phrase this any better, sorry) and I really want Firefox to display the drop down menu like it is supposed to look: the colors themselves underneath the text. (it looks like Firefox on mobile now if that is any help in figuring out where to start, but I don't see why it would fail to show the site correctly on desktop)

The part of the site in the first two pictures is accessible without an account: Scrying Workshop

Edit: It occurs to me that I probably should list what I've tried already. - disabled enhanced tracking protection - checked my settings (colors are not overwritten) - tried it with a new profile - disabled all extensions - reinstalled Firefox

Try to get "tvlistingszap2it.com" --(which I have been using for 5 years)--- but it opens "newsnation" Started doing this on 17 Mar, 25. What is wrong ?? Can you fix it ??

Why is there a setting that doesn't do [expletive]? Picture-in-picture can't be disabled through settings or about:config..... So how the living [expletive] do I disable [expletive] buggy [expletive]? And how the [expletive] do I set it to continue playing even after closing the small picture? Why is there no [expletive] setting for this while you have a setting that doesn't do [expletive]?

I reinstalled FF on 30 Apr 25 and it performed normally for a few days.

It is now 3 May 25 and we're back to where we started.

I started FF and I'm getting the tour screen on one tab, the privacy notice on another

All the tabs I pinned are just spinning their wheels

And all my extensions are gone.

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks
