Seems to be broken on FireFox version 145.0, 64bit Win 10

Doesn't work. Pinned tabs still disappear.

This addon removed all my pinned tabs. Now they are gone. ... Sucks!

After re-adding them, they get loaded automatically with each new firefox-start. I.e. the addon ignores the set firefox rules on when to load them.

Removed it.

huh? It totally removed all my tabs and won't let me re-add them. Removing!
