Lolu chungechunge lwavalwa lwabekwa kunqolobane. Uyacelwa ubuze umbuzo omusha uma udinga usizo.

I have FireFox Quantum Beta and am having issues with it chewing up alot of memory (7gb!). I do have a screen capture of the task manager

Kuphostiwe

Hi. I was having an extreme amount of slowness on FireFox Quantum Beta (version 57). I had the slowness just before and after a new update was installed (11/13/17 at about 10:45AM CDT). I captured the Task manager just before and after the update. I know that there is a legacy Flash plugin but it is set to never activate. How can I get rid of it permanently?

I was able to remove the Flash plugin from appearing on the plugin page by uninstalling it. I don't think that was the issue because it was set to Ask to Activate when the crash occurred. But now it doesn't appear at all on the Add On page.

I don't think this problem was solved with Flash. Right now I have 22 windows open on FIrefox. All but three are just regular Twitter tabs. Why is the top Firefox channel puling 1 GB?

So now with your recommended fixes I have cores that have 300 to 600K memory usage. Is this expected? I purposely have some heavy hitters open like YouTube, Yahoo, Gmail, newspaper website. Is this normal? It seems more stable. Time will tell.

Unfortunately I feel the same but yes. Version 58 will have multi-thread support so it should come down sooner or later. Is a lot better than gigs+++ you were getting though. Mine is about 800 to 1500 with 10tabs + open depending on what.

So do I need to monitor the memory usage periodically and do the process you described every so often? How long does it take for the system to bog down again?

So if you look at the task manager how much memory is Firefox using? You might have multiple instances of Firefox. One for each processor core. Right now I am showing between 77KB and 1.1 Gb with 21 tabs open.

Hi runnersweb and smoddelm and ogam5 and Pkshadow-

I have found this solution (see below) to also be very helpful. I performed the solution that Pkshadow suggested above and marked as the solution first. It brought memory into more tolerable range of 1.5 Gb. But just today I found another solution by Pkshadow. Here is the scenario.

I have 21 tabs open in Firefox 57 (Yahoo Mail, Gmail, 3 actively running YouTube, rest Twitter).

My desktop: i7 processor, 16Gb Ram, Windows 10 Home, Memory usage is about 39%. Task Manager details shows Firefox using 7 cores ranging from 22 Kb to 800 Mb. Very consistent performance.

Thanks to the help of Pkshadow - https://support.mozilla.org/en-US/questions/1188043

"You could try this please : Go the Menu then Tools --> Options --> Performance and untick everything. change the recommended size lower then see how it runs. Hardware Acceleration might have also been a issue so turn it off. Run it later and see as you turn things back on and test it, and again. Restart Firefox after making these changes please.

Please let us know if this solved your issue or if need further assistance."
