Previously, I didn't have any problem even with 30+ tabs.</P><P>After running the profiler with "Firefox" settings applied, I found that the "Parent Process" reports a "Jank" event for the duration of the freeze. See screenshoot below.<BR /><BR />Has anyone encountered this? I analyzed the other processes and it doesn't seem to be caused by an extension or a web page.</P><DIV class="">&nbsp;</DIV><P>&nbsp;</P> Sun, 06 Oct 2024 20:14:58 GMT https://connect.mozilla.org/t5/discussions/freeze-jank-after-updating-to-130-131-when-handling-multiple/m-p/73392#M28182 robertgr991 2024-10-06T20:14:58Z https://connect.mozilla.org/t5/discussions/freeze-jank-after-updating-to-130-131-when-handling-multiple/m-p/73393#M28183 <P>After further testing, this seems to happen when scrolling the Tabs bar at the top.
