--- Comment #1 from Graham Perrin <grahamper...@gmail.com> --- Created attachment 230658 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=230658&action=edit Screenshot: a Tree Style Tab view of various representations of non-loaded states > -- maybe only if no favicon is apparent before the click to load. Attached: a copy of my screenshot from <https://github.com/piroor/treestyletab/issues/2845#issuecomment-1000836106> I should not complicate this bug 260901, however it's worth noting (from <https://github.com/piroor/treestyletab/issues/2845#issuecomment-1000880498>): >> I'm getting duplication of tabs in recent days, difficult to >> diagnose, but I'm slowly gaining the impression that it occurs: >> >> * only if the tab is without a favicon when clicked for the >> first time (after the Firefox startup routine finishes >> opening previous windows and tabs). >> >> I have been unable to refine the bug to any particular extension, >> or combination of extensions. >> >> I began wondering whether the issue is with Firefox, then found my >> April 2021 issue 2880 involving duplication (closed, >> not a TST issue), then found this duplication-related issue >> #2845 with the Firefox-issue label. Note: duplication also occurs when extensions other than Tree Style Tab are in the sidebar and are used to load tabs. Now: * if there is _truly_ a performance-related bug involving an excess of processes * and if the excesses are a consequence of the duplication described above * is it possible that some combination of extensions triggers this bug 260901? On one hand: I do have an unusually large number of extensions enabled. On the other hand: I should not expect the design of (upstream) Firefox to allow any extension to cause loss of effectiveness of recommended performance settings. -- You are receiving this mail because: You are the assignee for the bug.
