Periodically Firefox increases it's memory usage and becomes unresponsive. I have seen usage up to 10,000 MB I then have to End task it and restart. I then works fine until the next time. I have run without add-ons and with a new profile and it does not make a difference.
For this and many other problems, it is always a good idea to specify the Firefox version (if not the latest) and the operating system.
The account signature makes this easier. I am surprised that it is not used much on this site.
This problem seems to pop up after recent updates... I am using build 101.0.1 64-bit on Windows. If you keep the Firefox running for a while, it will just increase the memory usage to a level became totally non-responsive. Every time, I had to use Task Manager to kill it.
What is going on? This has been a few months now... what was the technical cause? When this will be fixed?
Fire fox 101.0.1, MacOS 10.15.7
this is horrible on Mac/Linux. If I kill "Firefox Isolated Web Content" processes that seem to accumulate, especially after laptop sleeps, it clears up. Only a few kill current tabs, so these processes are danging out there taking up resources, slowing everything down and preventing Firefox from running tabs correctly.
At this point, I am switching back to BRAVE browser. I went to this other browser months ago and it doesn't chew up the memory, like Firefox does. I've used Firefox for years (yes, I have the latest updates) and Firefox is too much of a memory hog. It isn't my computer, as Brave I have no issues with. 😞
104.0b6 (64-bit) Windows 10. Same here. I've had it a few times recently. Am on the beta channel as usual. I notice when sites stop loading. I use a lot of pinned tabs and usually a number of other ones as well.
This is still an issue [v107.0.1]. Same number of tabs and opened fresh after shutting down Firefox. 10.7 GB !!!!! and in Microsoft Edge 02.1 GB. What could you possibly need an extra 08 GB for? What? I have been using Firefox since I think before 1.0 but this is crazy. Even with 32GB it does not make sense. 7 youtube tabs and 2 web page tabs.
Just piling on to this thread since it's the most recent one I can find. I'm having the same re-occurring issue here:
- Firefox has random bursts of being hungry for RAM seemingly out of the blue. This has happened on two otherwise very capable machines.
- The screenshot below is on my brand new top of the line M2 MAX 16inch MBP with 96GB of RAM. I use an app called "Memory Clean" to keep track of performance, and with only Firefox and Mail apps open, Firefox suddenly got laggy, popped the famous color wheel replacing the cursor, and Memory Clean was showing ONLY 6GB of RAM AVAILABLE what the hell!
- The screenshot is after doing a "memory clean", said app freed up roughly 20GB of RAM, and still showed Firefox as using a whopping 51GB of RAM. I did have about 30 tabs open but that's never been an issue before this started happening fairly recently. Seriously what's up with this?
- First time I experienced this a few times was with my previous laptop over the last couple months, a 15inch 2017 2.9GHz intel quadcore i7 with 16GB of RAM, and the behaviour was the same observed through the same app. About 12 tabs open at the time. It just keeps going eating all the available RAM, whether you have 4GB or 16 or 96GB of RAM.
(Both times on most recent versions for either system on Mac OS Ventura 13.0 and 13.2 - FFox V 109.0.1 64-bit)
Having memory issues 113.0.1 (64-bit) on Windows 10H (10.0.19044 Build 19044).
Over time memory usage keeps increasing even if only a single tab is open. Eventually FF becomes unresponsive but keeps chewing memory. Only way to resolve is to kill via Task Manager. Afterwards, the problem seems to be much accelerated. Is there some issue with the latest MS update? I am speculating but think that is when the issue kicked in.
Have just re-installed FF from fresh download and crossing my fingers that on top of the latest MS will solve issue. If this doesn't solve it, after many years will need to move to other browser as can't afford to keep losing my work.
