Firefox 社群討論區

i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

My Firefox 150.0.3 (64-bit) in Windows 11 on a Dell 9310 locks up when the XPS is put sleep and awakened after 5-minutes or so. No recent Extensions or Add-ons have been installed. I have yet to delete and reinstall Firefox, maybe that's the next stop. I just can't find the problem with my limited tools and experience. Thanks, and appreciate the help.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

I've done recent updates (May 2026) and after having 3 updates in recent months, I still have difficulties with my video programs (both Zoom and "One-click) slowing down during my work which is 100% virtual. How can I revert to an earlier version where this was resolved, please!!??

I get REAL tired by the amount of resources Firefox eats up with each open window. For whatever reason, having multiple windows open prevents Facebook from loading. I'll get 1 story and a "shorts" bar but THAT'S IT. Even clicking the story to rate or comment does nothing. If I start to delete windows; it will decrease the memory usage and then it will open.

However, I DO NOT WANT TO CLOSE MY WINDOWS IN ORDER TO OPEN FACEBOOK! Firefox should not be eating up that many resources. The open windows are of text and/or picture archives. There is no sound or video playing in the multiple windows open. My system literally has 128 gigs of ram memory so it seems very odd to me that Firefox is using between 11-13% with nothing running in the 15 windows I have open.

Hi there,

I am on a MacBook Air M3/8GB ram. I was really wanting to use Firefox due to your stance on privacy, etc. but here is my experience:

Yes, I keep a lot of tabs open - I do try to group them and hope that tabs in closed groups are deactivated, but I don't know this at all.

If I use Firefox all will seem well until my machine sleeps. On waking, it is excruciatingly slow - we are talking multiple seconds to even switch tabs or get the cursor to be "hot" when filling a form. Upon trying to quit (restarting being the usual first step), FF will ask confirmation and then close the windows, but will not completely quit, requiring me to force-quit. On restart it seems to behave again, at least for a while.

While I do see some evidence that others have this issue (memory leak?) there are no real methods or answers as to how, if at all, to fix this. It took a lot to get everything on FF working the way I like after leaving Chrome, but I really can't deal with this, and I think I will be looking at switching again - I guess to Safari.

I would love to know how to fix this, but really I don't imagine this is due to my system as much as the FF browser. That said, if you ahve any ideas, I would be open.
