It works in general, I started to use it when Firefox changed its sorting algorithm in Windows dropdown menu on macos (around version 108 in 2023). It was useful that time. It also works on linux, but it is not that useful. It's a pity the extension is not able to rename windows in "recently closed windows" tab about:firefoxview#opentabs Although this may happen due to inconsitency in Firefox windows naming as mentioned in github.com/tpamula/webextension-window-titler/issues/43

Anyway, the extension is not developed for few years.

The way this addon names/"titles" open Firefox windows feels a bit janky - it just adds a user-defined string of text to each tab - but the end resullt is better than nothing. The names also don't get added to, say, screenshots of webpages, which is great.

This functionality honestly should be a part of Firefox by default, and then also presented a bit more neatly. But kudos for this addon nonetheless.

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.

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

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.
