this browser does nothing but eat and eat recourse. no matter what i do, no action ever stops it from hogging nearing 1/3rd of the resources of my machine all the damn time! And i dont want to hear virus or malware anything. i have swept, checked, and swept again. nothing is ever fucking found. And i do not trust the other browsers. so i guess i am just OFF THE INTERNET

For a few months I have been having sporadic issues with my cpu running at 100%. I believe Firefox is the culprit. When I open task manager Firefox is running 30 processes with power usage very high. Usually one of the top processes in the drop down is very high. To fix this I have been ending the task of the highest usage process running. In all cases that has brought the cpu down to like 10% and has fixed the issue temporarily. If I'm not at my computer for some time, it will not resolve on it's own. I'm not sure what info you need but will provide. Could this be a bug with the current version of ESR?

I have tried the fixes including: Disable/Enable Hardware Acceleration, Enable Strict Tracking Protection, Delete content-prefs.sqlite file, Check Firefox hardware acceleration, Disable resource consuming extensions and themes, etc.

I am using Firefox ESR 128.6.0 and have been for years (ESR)

Hi Community,

I am writing as recently I noticed that extreme amount of data was written on my system SSD. Here we are talking about 100-200GB of data written daily. In resource monitor I found that Firefox is writing this amount of data in its Profiles folder, but only when Facebook's main page is open. I also noticed that when only the Messenger part is open the problem goes away. Currently I symlinked the Profiles folder onto one of my HDDs so the data is being written there, however I would like to know if anyone experienced the same issue and what could be the solution for this. I completely reinstalled Firefox, my installed extensions are Adblock Plus, Enhancer for youtube and Facebook Container.

All of a sudden, I get a "Not enough room to save" error message when I try to download a fill. There is plenty of room on my disk.

Also, it's not giving me the option of just opening the file.

I've been needing to use Edge to download files.

Greetings. I have Windows 10 Home and have used Firefox for my primary browser for many years. I recently noted that by opening Firefox and looking at my task manager it shows 14 processes running. This causes my memory usage to jump significantly from the 50's into the 70's. The performance on searches,etc. seems okay. I recently added Browser Guard and was wondering if that was the reason for the jump in memory usage. As a side note I ran an update on Onedrive and now I have a white circle with a check mark on the desktop shortcut that I use for Firefox ... Thanks to all for any assistance regarding these questions ....

Semaphore.social is a mastodon/fediverse web client. I've been using it without issue up to now and it has not updated recently.

After a few hours running the CPU usage of Firefox becomes very high (25-50%) and the about:performance shows that it is due to this tab, which shows at values from 110 to 160% or thereabouts.

I haven't noticed this before updating to Firefox 134.0 so I suspect it may be a Firefox regression.

However I cannot work out what the cause is, how to fix it, or if I should file a bug on it.

Any ideas on how I can fix this?

Hi, I'm using FF for year for development and had several problems with cached data in this time. Now, since the last update (automatic update yesterday), Firefox is caching my js for localhost and ignores nearly everything to stop it.

F5 and Ctrl+F5: no effect Enabling "Disable cache" in devtools: no effect changed about:config (no effect): browser.cache.disk.capacity 0 browser.cache.disk.enable false browser.cache.memory.enable false devtools.cache.disabled true

Only going to settings > privacy + security > Clear Data helps. But as you can imagine, that's really bad DX

I tried a FF-addon for clearing css cache, but it's outdated and doesn't work.

Is there anything I can do, to disable cache for localhost?

I don't understand why this aggressive caching problem is ignored for years and gets worse every year! Why are settings like "Disable cache" in devtools so broken? I tested other browsers and have not found the same issues. I don't want to switch browsers! I just want a cache free localhost! FF can cache the sh*t out of every webpage. But please leave localhost out of it!

Hi, I have 32 gb of memory in my system and I'm having an issue where firefox is taking up most of it but only reporting 1 or 2 gb in task manager. Im using the windows powershell command Get-Process | Sort-Object -Descending WS | select -first 1 | select -ExpandProperty ProcessName to find whats using the most memory and its listing firefox, heres a screenshot showing the issue.

Whenever I restart Firefox, it uses about 30% of my RAM, however this increases over time and after a week it can be over 60%. No new extensions, tabs, windows opened, nothing changed from usage of day 1 to day 7. I have attempted everything in the support post for Firefox taking up too much RAM, and nothing has led to longterm solutions. This issue originally started about 2 months ago so it hasn't been consistent, but I haven't changed anything either in my browsing habits or the hardware of my computer to causes this change. Hardware acceleration is off, and using the same extensions (and more) on other browsers doesn't result in the same problem on those browsers. The problem is worst by far when I'm using YouTube.

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?

I am trying to troubleshoot a problem with high CPU usage by Firefox when using Mozilla VPN - VPN ON.. Problem occurs when starting in Safe Mode, and still occurs after performing Refresh. Problem can also occur just by changing to a new tab. Problem does not occur if Mozilla VPN is turned OFF. Problem does not occur with Microsoft Edge. Mozilla VPN Support said it is a Firefox issue, and recommended contacting Firefox if safe start or refresh did not help.

Hoping that someone can help me solve this issue. Thanks!

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.

I believe this problem began in 133. I've noticed that if FF is open for a few hours, it starts to develop a very noticeable input lag. For example, if I'm watching a YouTube video and hit an arrow key to advance the video, there will be a couple of seconds before the browser registers the key press. It behaves like a high CPU issue but I do not detect high CPU usage when this is happening. Restarting the browser resolves the issue for a few hours.

This is happening on Windows 11 as well as on a Mac running Sonoma.

Firefox prompted me that my local storage space was insufficient. When I opened the data management page, I found that a particular website's local storage was abnormally large, and some websites were inaccessible or unable to log in. After restarting Firefox, the issue did not reoccur.
