Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!

Hello,

When I opened Firefox this morning, it downed the newest version.

Since then it becomes nearly impossible to use, locking up after a few minutes.

Are you aware? Is this being fixed? Can I go back one version? I used Windows 10, is that the issue?

Thank you.

I am having a problem with Firefox on Linux Mint. Firefox has completely stopped responding. Even the buttons like close, back, refresh, or menu do not work. The whole browser has become frozen. Shutting down or restarting the system doesn't work.

Firefox version: Mozilla Firefox 151.0 My system: https://termbin.com/s387

Sometimes, for no apparent reason, on my Win 11 ASUS laptop, Firefox will suddenly use a lot of resources, such that the temperature jumps from about 50 degrees to 95 degrees and the fan runs full speed. It appears the only way to stop it, is to close FF then reopen. What might cause that?

I also have an unanswered previous question about being unable to pay accounts.

Cheers, Keith

Kubuntu 24.04 with various Firefox iterations including 149.0.2. It happens on stand alone, snap and flatpak versions. I do not know what triggers this problem. As far as can tell it only occurs on Wayland and not on 'X'. .... After using Firefox normally for a while I first notice the problem when I can't click into the separate search box on the toolbar, then I find I can't drag the tabs around as per usual. Then, if I click on a toolbar icon it does not respond. In summary, the toolbar becomes inoperative. I do have 9 pinned tabs but I can often have many more standard tabs up before I ever notice the problem and, today, when it occurred I only had 3 additional tabs up. So, I can't tie the problem to the number of tabs.

My mouse (wheel) only works on the portion of the page that is currently visible; it will not scroll down the rest of the page. This problem began after 151.0.1 update just a few days ago. It works correctly in other applications such as word or excel. It also works correctly with other browsers, so it is definitely something in Firefox. Any ideas?

I noticed in the past day that Firefox started using alot of ssd. It wasn't doing this before, I've been a Firefox user for years now. I'd like to stay that way rather than going with Google or Microsoft. I don't trust some of the other small companies with browsers. I like the fact that Firefox uses it's own engine too. In the last day it started using alot of disk for no reason. How do I fix this. Well, well, well. I just noticed that Icloud from Apple was using alot of disk too and when I shut it down in task manager it stopped. Firefox disk use is virtually none just like Microsoft Edge. So it's some kind of interaction with Icloud that is causing that. But it wasn't doing that before. I have task manager open most of the time to catch stuff like that. My system is decent I have a 2TB 990, 2TB 980, and a 2 TB 860, with and AMD 5800x, 32 GB of ram and an Nvidia rtx 470. Maybe some kind of backup with Icloud was happening, that isn't with Edge. So I know shutting that off works. Icloud is useful for backing up things from my phone though.

I'm experiencing an issue with the latest Firefox update. If I refresh a link/page the browser "spins out" in a rapid endless refresh cycle. In some cases, I receive an error message, "too many requests," and in other cases, the browser "locks up" and quits responding at all.

Is this a known issue?

MacOS, M2 2023, fully up to date firefox.

Sometimes I'm using firefox and it just stops loading pages, internet is fine. Other browsers work. I look at my activity monitor and nearly 100% of my 32GB of ram is being consumed by various firefox processes. A lot of those processes seem to be associated with youtube. This problem usually, but not always, is resolved by restarting firefox. But this shouldn't be happening. I have a lot of tabs open sometimes, but it's not that excessive. And most certainly not 32GB worth and preventing my computer from doing a google search.

If there's a debugging thing I can do to post system logs, let me know and I'll post them next time this happens. I'll be away from my computer until early July, so around that time.

When i start to use Firefox and browse internet, usage of ram memory slowly rise up to max, using 5-10 GB, i disabled AI, same problem, don't know if something with Youtube causing this, every open tab is consume too much of ram memory. I think it started yesterday or day before. Installed again Firefox, same problem, if i have more open tabs, quickly rise consumption or ram, i have 16GB. Now 4 tabs, FB and 3 Youtube, more than 5.6BG. In Task Manager shows Firefox (20), 20? only 4 tab open and ram rises.

Since latest update when trying to view pages with artwork on them I get a message that the page is slowing down Firefox and asks me if I want to stop the page to speed up the browser. I do not want to stop the page so I click the X, but Firefox refuses to load the pages at all anyway! I can no longer view many sites due to this issue. Please get rid of this awful code! Thanks.

power up and get previous home page with bookmarks page from prior session. cannot delete page using 'x' upper right. cursor not effective . I have to click on firefox logo to start a new session. Note the old display comes up at each login. Cannot delete I must overlay. Please help. Greg

I am facing a recurring issue while browsing websites on Firefox. This happened even before the latest upgrade. Only it is worse after this last software upgrade.

After using the browser for 1–2 minutes, the browser gets stuck or becomes unresponsive. While scrolling through websites, the full page does not load properly, and parts of the webpage suddenly become blank. In many cases, the existing tab cannot even be refreshed. I have to close the program, wait a few minutes and reopen. Very frustrating. I have been using Firefox for many years and this is the most unstable I have ever seen it. Browser Version: [151.0.4(64-bit)] Operating System: [Windows 11]

Looking forward to your support.

On a random basis, sites like msn.com, yahoo mail or outlook.com will freeze. Sometimes they may suddenly come back to life, but the normal fix is delete tab and restart tab. Long videos may also freeze. Have cleared history, and changed optimization setting but nothing helps. On 151.0.2 64 bit.
