Titles missing after restart (confirmed bug), dev abandoned it

tl;dr: does not work on Linux

Longer version: the two ways to activate this add-on do not work:

Toolbar button (t icon) -- does not appear when Firefox is running (Debian Linux with KDE).

Keyboard shortcut (Ctrl-Alt-T) that invokes Window Titler is already reserved to invoke the prefered Terminal App on most (probably all) version of Linux.


Suggested resolution by Developer: make the shortcut configurable. There's a good chance this will solve the toolbar icon problem

Does not save the titles after restart.

unfortunately, as some comments already say : the name of the windows is often lost. So it's useless. I wish it to be fixed asap.

02 april 2024: for the last few weeks, it constantly loses the titles while you work. Often, you can find the title in the panel opened by the icon, and reassign it. 5 minutes later, it's gone.
If I close a titled window, all the others lose their titles.
close and restart the browser is hit and miss.
Maybe this is due to the huge amount of add-ons I have (active: 75), but none deals with windows titles. or maybe because I reverted (smooth operation)to FF 115 ESR when I got v121 of the normal release.
TabSessionManager used to record and restore the titles perfectly, but then the restore part started messing up, so I started backing up with TSM and restoring with the windows setting General ->Startup->Restore Windows. This also has stopped working: titles are not reloaded.

Is the module corrupted? It doesn't let me install it.
