1929076 - Facebook Text & Chat SLOW. unsuably slow, since autoupdate to 132

Status: RESOLVED WORKSFORME

(Core :: Performance: General, defect)

Description

[pheedme]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:131.0) Gecko/20100101 Firefox/131.0

Steps to reproduce:

Firefox Autoupdated ( BOO! Have since disable the "feature" )
Go to facebook.com

Try to use Chat, or post anything ( Post comment, edit comment. Load chat window , ype tect in chat window )

Actual results:

The browser tab would lock up and respond like i was using the net on 1200 Baud modem. We have gigabit internet.

Expected results:

IT should have responded snappily like Release 131.

Please note before downgrading i tried clearing cache etc. Made no change.

Fixed by Downgrading to 131. ( New profile was created in the process... this may or may not have been what helped )

With Firefox updated to the version where you see this issue:

1. Go to "about"support" in your browser and copy-paste its contents here
2. Capture a performance profile using the Fireofx Profiler (https://profiler.firefox.com/)

You said that V131 works perfectly. Would you be willing to perform a bisection using the mozregression tool (https://mozilla.github.io/mozregression/) to find the exact change that causes this issue for you?

Attachment: Raw data from FF 132 about:support

I have no idea, even from the documentation, how FF profiler is supposed to work. I have the same problems documented in the original post, and have attached my about:support raw data here.

Could you please try running the browser in Troubleshoot Mode. It is available in Help->Troubleshoot Mode. This will disable your addons and help rule them out as a culprit. Thanks!

@denispal I ran in Troubleshoot mode, and performance speed increased to normal. Again, for me anyway, Facebook is slow in FF and no other browser. And in FF, nothing but Facebook is slow. But Facebook in Troubleshoot Mode is not slow like it is otherwise.

If it runs fine in troubleshoot mode, then that points to an addon problem. I would disable your addons one by one to see which one is causing the problem. Please let us know which one it is and we can try to notify the author. Thanks!

Could you let us know if this suggestion in comment 6helped to resolve your issue?

Within a week - I think - of my posting this, FF had updated and the problem went away. It continues to not be a problem now that I'm running 133.0.

I never did go into troubleshooting mode, but for my current configuration I am now running everything fine.
