Massive CPU Usage Suddenly on Nightly #1388
Comments
@mbnuqw , there is an important problem here, on Firefox 122-123 Sidebery constantly loads processor |
I've found revoking History permission in Sidebery settings reduces CPU utilization back to normal levels on Firefox 122 beta X and onwards. It apparently also disables History panel for users that rely on this feature. So keep it in mind. |
@serdarth what made you think to try this? it does seem to help significantly for me as well. |
@colemickens good ol' trial and error actually. I thought it had to be one or a combination of the settings after creating a fresh Firefox profile and not reproducing the same behaviour on said profile with default sidebery configuration. |
Steps to reproduce
Hi, I don't know if this is due to a recent change in Nightly, but I noticed that Firefox was eating a ton of CPU and Firefox's Task Manager indicated that that was due to a WebExtension.
I pretty quickly narrowed it down to SideBery.
This is with Sidebery disabled.
This is immediately after re-enabling it.
and it stay this high. In my non-work profile browser, I have considerably more tabs, and the problem is worse. I'm sitting at huge idle CPU usage, with literally every tab unloaded.
I'm not sure how else to help investigate, unfortunately.
I can't share logs from this session as it's my work browser. Later, i can repro in my other session and provide that log.
