The existing excellent reviews are hard to fault! - a great utility and I am so glad to have found it.

If I could add an observation, it is this: I keep wanting to reorder the list of Windows that are presented when you hover over the Firefox Icon (in Windows) - that would make a fine enhancement imo. A right-mouse-click to the context-menu could present "Sort" and offer the following "by" options: Alphabetically, and chronologically (by creation date, by last modification date & by last used date).
You might even be able to add a drag & drop facility too?
Thanks so much for building and offering this Tomasz - it makes it possible to work efficiently with hundreds of open tabs.

Also, the developer of All Tabs Helper, Kevin Jones, https://addons.mozilla.org/en-US/firefox/addon/all-tabs-helper/reviews/ has retired from duty and is encouraging developers to fork his code to continue as they wish with that marvelous product. Perhaps some features would make great enhancements to Windows Titler?
One that immediately comes to mind is another context menu offering to kill all active sessions - IE to stop them robbing bandwidth. That saved me from rebooting on many occassions so it must have released the memory consumed too.

The other obvious one is to add functions to that described above to facilitate drag and drop of tabs *between* windows.

Thanks again :-))

Does exactly what it says on the tin. Very useful if you work with multiple windows.

This is exactly what I'm looking for! It names the Firefox window title! Works perfectly fine!

Perfect. Especially love that it supports emojis. ♥

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

you to add the word "RENAME" prominently so it shows up on the search: "Rename Window" -
Missed this since I switched 'puters. Works great. Occasionally goes tilt - don't panic - restart FF.

Combined with KDE's "Activities", and the "Simple tab groups" extension, and a few other things not related to FX, this extension finally allows me to have multiple "workspaces" all easily distinguishable.
Thanks!

Simple and to the point. No bloat and excellent add on.

Exactly what I was looking for! I use multiple windows to keep my tabs somewhat organized by task, but it can get a bit overwhelming remembering what tab I was on in what window. Being able to title the window solves this issue perfectly. It even remembers the window title after I've quit and relaunched Firefox.

The only change I might suggest is disabling the tab title, allowing only the window title to be displayed.

Rarely does one find add-ons or extensions that become so integral to one's workflow that it makes it hard to use other browsers. For me, this is one of those add-ons. If you like to organize your tabs around tasks, topics, or projects, this add-on in indispensable in being able to quickly task-shift within a browser. It's interface clean, easy to use, simple to understand and customizable. It also plays nicely with containers for the ultimate in separation of concerns. Thank you, Tomasz, for creating it; it's very handy.

This is a great add-on for complex setups.

I'm using a pathological number of FF windows, scatter among 12 desktops for various topics. It helps me to organize and manage this state better than ever.

While at it, and since I suffer from a session store issue of FF https://bugzilla.mozilla.org/show_bug.cgi?id=372650 since a long time, I created a small tool, that allows me to store and restore the FF session state using the static titles of this add-on:

Thank you, Tomasz.

Perfect with a window manager that can move windows to another workspace based on window title!

This add-on is simple and works well!

Wonderful, as I organize my windows by topic, now when I click on firefox icon in my (Windows) taskbar, I can see the topic the extension lets me set! Without the extension, the Firefox window titles are just the last tab's title, and it was impossible to quickly find, for example, my "email" window, or my "travel planning" window if I'd gotten, say, wikipedia open in both windows.

Thank you!
