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

Awesome little helper. I use it together with a mod that lets me shorten task bar tabs. Makes my life as a tab hoarder so much more tidy. :D

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.

Using for KDE Window Rules. I need to differentiate between various FF windows to handle them differently. Setting the window title makes it possible as otherwise all FF windows have the same window class/role/type/everything.

The only drawback is that the title is not set immediately when the window is created, but only several milliseconds later. Causing flickering.

Works well for me so far. Even remembers titles between sessions. Update: titles do disappear once every 2-7 days or so, from all windows at once, but they're remembered when opening the plugin, so you just gotta open it and press enter for each previously named window, when that happens.

Also, i love that these features are included:
Customizable keyboard shortcut, customizable brackets around the title and option for auto title prefix.

Works well. It'd be nice if the custom titles showed up in the History > Recently Closed Windows menu, but perhaps that's a limitation of Firefox?

Essential for auto-placement with a sane window manager (like sway …).

Does its job perfectly!
