Incompatible with Move unloaded tabs for Tree Style Tab: tabs can not be activated|switched via TST 3.4.1 (2020.3.6)

[drsvp]

Following my update to TST 3.4.1 (2020.3.6) i can no longer activate|switch to tabs via TST; rather, i have to go to the default tabs bar in Ffox to activate|switch between tabs. Prior to the TST update, it switched tabs when clicked on.

Steps to reproduce:
• Place mouse cursor over tab to be switched to
• The color changes indicating focus
• Clicking on the tab(s) does not switch to|activate them
[note: clicking an X to close a tab via TST works normally]

i restarted Ffox once the issue started but it remains for me
i added no additional|new addons along with the TST update (i do still have 70+ other addons running, tho only a half dozen or so of those are tabs specific)

Ffox 73.0.1 (64bit)
TST 3.4.1 (2020.3.6); dark theme
Windows 7

Thanks!

This looks similar to #2503. Do you use any other addon extends TST?

Indeed, i have Move Unloaded Tabs for TST installed; deactivating it corrected my issue; activating it again causes the issue to return for me.

jic, i had it installed prior to the TST update to 3.4.1 (2020.3.6) and did not have this issue.

Thanks, I've confirmed the problem with installed Move unloaded tabs for Tree Style Tab.

I forgot that TST's tab activation behavior was changed at a version between TST 3.0.17 and TST 3.1.8. Before 3.0.x, TST switched tab focus at the timing onmousedown. But 3.1.8 and later switched tab focus at the timing onclick - after onmouseup. "Move unloaded tabs for Tree Style Tab" was initially developed for TST 2.x but it actually (and unexpectedly) became unneeded for the purpose described at its name.

Hmm... I missed that the behavior was actually changed with the pull request https://github.com/piroor/treestyletab/pull/2306/files and I didn't mentioned that totally...

I've uploaded TST 3.4.4 to AMO with the fix. Please wait for editor's review...

Just a quick confirmation that Mozilla has released an update of TST to v 3.4.6, March 12, 2012
More after i've had the time to put it through some routines... including reactivating Move unloaded tabs for Tree Style Tab ...

The issue with tabs in the TST sidebar being unswitchable with Move unloaded tabs for Tree Style Tab enabled seems to be resolved for me! Working as expected.
Thanks!
