This may be an old problem. In Linux, in bookmarks library, the scrollbar thumbs behave differently than in browser web pages. Even in new profile. This isn't a new issue for v157. Same behavior in any theme (any Fx themes, and / or diff 'Nix system themes).

I set scrollbars to disappear when not used or being hovered. On sites, when hover scrollbar area, they reappear. AND while pointer is over the track or thumb, it remains visible - does not reduce to an unusable width or disappear completely. As I think it should.

But in bookmarks library, the track & thumb disappear, even w/ pointer hovered, unless thumb is grabbed immediately. Even grabbing thumb & move it, then pause a fraction of second (still gripping thumb w/ L mouse button), the thumb & track STILL disappear. As long as you don't release grip (on now invisible thumb / track) they reappear when move pointer.

The bookmark library scrollbar behavior is also erratic. How long you have to grab it, when you 1st hover it. If you accidentally move pointer from folder pane, past vertical divider into bookmark pane, then left - back into folder pane, the scrollbar doesn't appear.

You have to move pointer well left of scrollbar, then approach it from the R, to make it reappear. It doesn't have any of this behavior in the browser (never has, AFAIK).

My Macbook Air (M1, 2020) has be moving slowly recently. I wondered if how I'm using Firefox could be contributing. I typically have two Firefox browser windows open, with 5 or 6 tab groups each with several tabs.

In addition and more specifically, I'm wondering if closing (collapsing) a tab group means those tabs won't be contributing to my computer's CPU load. Thank you.

Open a website in one tab.

Open a second or third tab and try to switch between them or browse.

Observed result:

The browser stops responding, freezes, and fails to load or switch tabs smoothly.

If my Macbook Air Activity Monitor shows that Firefox GPU Helper is using most of the memory, could that be what is slowing my Mac down?

Hi. My Macbook Air (M1, 2020) has been performing slowly in recent days. I'm not playing video games or watching videos, just mostly working on many tabs in Firefox (157.0.1). I looked in my Mac's Activity Monitor, which shows that Firefox GPU Helper is using about 5.75 GB of memory. The next few highest users say "Firefox Isolated Web Content." Could any of these be what is slowing my Mac down? I'll attach a screenshot of my Activity Monitor. I also clicked "Share Data" below. I would say that my Macbook is working at a fine speed at the moment, so perhaps the screenshot and data are not so helpful. Let me know if I can add something later in a reply, when my Mac is moving slowly, that would be helpful. Thanks.

What the living hell is this? This is prevalent on every PC I've installed FF. Just starting a clean browser with a single tab use 19GB of RAM within 1 second... No wonder why browsing been excruciatingly slow since the previous update.

Yes, I use add-ons like 90% of the users, but that should not warrant a serious and consistent memory leak.

Firefox freezes some seconds or some minute after I open the program, I end task and wait to reopen the program, opening up the program it continues to freeze. I've reset firefox multiple times, cleared cache & webdata, completly uninstalled FF and reinstalled it, doesn't solve it. Starting firefox in troubleshooting mode also freezes and hangs. After end tasking firefox multiple times it eventually stops freezing but during the next day when I open the browser the issue returns, The same goes after I reinstalled it after uninstalling it, works for the rest of the day but the next day the issue returns. Background: I switched from chrome to Firefox some months ago and imported webdata from chrome to FF.

Re: https://support.mozilla.org/en-US/questions/1600764 . TL;DR, encountered this exact loading issue of firefox responding and after using a profile blamed it on a patience issue. I assumed so because my longest hang time would end up being ten minutes, which was the first time, never got past 5 minutes afterwards. Fast forward to now, it has been a few weeks since I used my pc due to general life business, so I had to turn it on, firefox opens, hang takes FIFTY MINUTES. I have also had to restart firefox several times due to missing updates and each and every hang time has taken a MINIMUM half an hour, and this is before giving up and closing the window on many instances. I have been sat here trying to do anything in firefox for over five hours now. The ONLY excuse that I can make up is the main reason I'm at my pc is because it needs updates and is currently downloading updates, so that is using a lot of my disc (I'm on an HDD if that's important), however it shouldn't take nearly an HOUR to use firefox for like a minute and then take ANOTHER hour simply due to hang time. I have also checked task manager and Firefox is using very little cpu (0%-2% at most) and not a lot of ram (initial hangs were down to ~50 mb, now it's around 300). The only thing I can think of is that the issue could be with the history file being corrupted, but since I have that synced with a mobile device, i don't know what that would do, nor do I want to lose my history, but otherwise i am at a loss and need more advice.

Firefox's performance keeps getting worse. I have to clear the startup cache several times a day just to get any sort of decent performance! Reinstalling hasn't helped, and disabling add-ons hasn't provided a solution either. Has anyone else experienced this, and/or does anyone have a solution to the problem?

I started noticing that Firefox was giving me a lot of "not responding" freezes the past couple of weeks. The past couple of days I basically cannot access Firefox at all - constant, immediate freezing. I have tried uninstalling/reinstalling (multiple times), disabling hardware acceleration, running troubleshooter mode (still freezes! if it opens at all!), deleting profiles, restarting my computer, etc. I've done just about everything I can find online about this issue. Nothing has worked. I have no issues with Chrome or Edge.

Any suggestions??

Hello Firefox Help Forums,

I have been struggling with a persistent issue for months now which is hard to fully describe, but simply put when I go to type in certain text boxes on websites, the input will repeat and cut random parts of the words, making it impossible to type anything coherent.

For example: "Hello world this is a test of typing on firefox" becomes: "HHelHH world this is a test of typing on firefoxello"

Backspacing to try and delete the text feels jittery as the letters take a long time to delete and can cause more garbled text to appear.

I have had this issue on multiple devices: Samsung Galaxy A54 5g, Android 16, Fennec 151.0.0 Google Pixel 6A, Android 17, iceraven-2.45.0 AND Fennec 157.0.0

I can replicate this semi reliably on the following specific sites: nekoweb.org/dashboard/editor/[page] (typing anywhere in the HTML editor) teams.cloud.microsoft (typing in the box to send a message)

If anyone has any idea on how I can fix this I would really appreciate it! Please let me know if there is any further information I can provide to help figure this out.

The keyboard straight up doesn't show up when I tap on writable spaces. Like this support page, twitch or other chats, search boxes on Ddg or Google, or many other sites with writable boxes. Sometimes the keyboard will show up but won't actually let me write anything, and won't go away with normal means. When I try to close it, it just goes back a page and the keyboard stays on the screen not functioning. It's quite annoying and won't let me do what I want. I wrote this in a notepad app and copy paste it, 'cuz it won't let me write anything on the support page.
