Diễn đàn hỗ trợ Firefox

before v151.0.2, didn't have a problem with firefox, now with this new release, it is really really slow, takes some time to start and load pages. what happened??

I open Firefox and Chrome with the exact same page:

Chrome is using 296 MB while Firefox is using 590 MB.

What am I doing wrong?

Anyone else had problems the last two weeks with performance? I'm on a macbook (Tahoe 26.3.1) and in the last two weeks tabs are constantly crashing or freezing. I have never had this before. It's doing my head in and I'm about to make the painful move over to Chrome if nobody has any ideas how to fix it?! I don't want to do that as all my bookmarks etc are set up on Firefox...

Dlaczego FIREFOX spowalnia i często karty się samoczynnie przeładowują? Nie zdążysz jednego artykułu przeczytać i się wszystko odświeża, cały czas się odświeża. Na konkurencyjnych przeglądarkach MICROSOFT EDGE i AVG SECURE BROWSTER cały czas działające odświeżanie nie występuje !!!!!

henn typing website keeps going to about blank/ crashes all time/ locks up unable to open sites like home depot/autozone xtra slow respondes. must be time to use something else firefox has gotten unusable

Dear Mozilla.

Yes, I'm using the dreaded Windows 10, I do understand it's at end-of-use, however this prob's been happening for ages. It's just got a little worse lately! (I've also got another hard drive with Windows 7 on it I swap the Windows 10 drive for sometimes. And we don't talk about the Windows XP hard drive with my music software on it. AARRRGGGHHH!!!! But the everyday drive with this problem is definitely Windows )

I don't use masses of extensions, just a VPN (which is there but not used a lot!) and is Proxy VeePN (that's its name, blame the designers, not me!) When I'm NOT using Firefox for a few moments, I hear the fans speed up, the hard drive spins like it's about to take off (old computer here!) The moment I touch the mouse, the fans all slump back to normal and the red 'HIGH USAGE' mark against Firefox vanishes back down to 'LOW'. Which makes it annoyingly difficult to analyze what's happening cos the moment I touch the mouse to find out what's happening, it stops happening!

Despite the above and its memory addiction - left to itself it munches memory like me with a crate of chocolate bars! - I do love Firefox best of all the browsers. I kinda know what causes the memory problem, by the way. I don't know all the techie terms but here's what's going on. Imagine you've got a house with an untidy kid in it. Every time one room gets too messy to use, you move into the next room. Eventually you run out of rooms. Then you restart the house back from day one, all the rooms are tidy again and you can use them all individually and happily - until Untidy Kid turns back up!

I'm on Firefox 148.0.2. If you've got any ideas about the CPU usage, I'm [email removed]@hotmail.com. It doesn't seem to matter what websites I've got in the browser, it just does this when I've got it parked in the background, it's like it's twiddling virtual thumbs through boredom cos it's not being used.

Yours respectfully,

Chris.

In a thread discussion about the flag, "browser.tabs.unloadOnLowMemory" dated 23-Nov-2022 (https://news.ycombinator.com/item?id=33706117) it was mentioned that we've disabled tab unloading on Linux because low-memory detection just didn't work.

Has the issue been fixed? Does the low-memory detection work in Linux? Can it be enabled now?

Does it get triggered when SWAP is being used? Or when system free RAM falls say to about 25% of total physical RAM?

I have been experiencing issues of extreme CPU consumption.

When I look at Task Manager, I see tabs consuming resources - tabs I have closed.

See attached open tabs screen shot, and task manager screen shot. The Register (tech website) is clearly consuming CPU and memory, even though I closed that tab yesterday. WTF is going on?

Linux Mint 22.1 Cinnamon Cinnamon 6.8.0-90-generic

Firefox is installed from the package manager, not as a flatpack.

Extensions: Privacy Badger, and uBlock Origin are installed and active on most tabs. (YouTube has become temperamental about privacy extensions, and a few other Google-related sites as well) CookieAutoDelete - though that just deletes cookies/sites data some seconds after a tab is closed.

The Register example is just for reference. The service that seems to consume large quantities of CPU, even after I close all related tabs is YouTube. It has on occasion made the system crash.

What minimum memory spec is recommended for current Firefox usage? Have new computer with 16GB memory, 512 storage, intel core Ultra 5-225 processor & windows 11. Have not set it up yet.
