Works as advertised, use it a lot! Excellent!

Since Mozilla misguidedly killed tab-groups, an organized user needs far more open windows. I now have three times more browser windows due to this horrible decision, and this addon makes it far easier to keep track of what they are for. It gets four stars because the title occasionally disappears after a browser restart.

Wow!

The whole point is to have a Shorter more organized name not a name twice as long with symbols and emojis, garbage.

Works like a charm.
(Titles are restored after closing a window or even killing firefox completely. I didn’t try a reboot yet.)

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

man klickt auf das Icon, Ein Popup Fenster erscheint, man tippt einen Namen ein, und ab dann heißst das Fenster "[eingegebener Name] Tabname"
also alles wie man es erwarten würde, einfach und funktioniert.

Works great on Mac, and Linux.

For those having issues accessing the shortcut because it conflicts with one previously set by your OS, or another extension, you can manage the shortcuts yourself - just go to your extensions page, click on the cogwheel (tools for all add-ons), and then select the "Manage Extensions Shortcut"

For those who don't see the toolbar icon, remember it may be hidden in the extensions icon (puzzle piece), if you haven't already opted to pin Window Titler to the toolbar.

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.
