Does its job perfectly!

「＜ウィンドウ名＞タブのタイトル」という形式で表示する事ができ、「ツリー型タブ」と合わせて便利に使っています。

作業目的ごとにウィンドウを作る使い方をする中で、開いているタブによってはウィンドウの役割が分かりにくい悩みがありましたが、解消されました。

Does exactly what it says. Love that it persists through session restore. Perfect little addon

Works as advertised.

Note on MacOS (don't know about Windows) that the named windows are alpha sorted when viewed by the Firefox Dock icon, but in creation order in the Firefox Window menu item. I actually like the two different views.

This extension allowed me to move from Chrome.

Works perfectly.

Does exactly what it says it does.

I'm sure there's a way to do this by digging through Firefox's internal code, but this dev already did it for us.

Thanks for making this, Tomasz Pamula.

Great extension! It's easy to use and has simple but useful options.

Awesome that this works and the title stays after restarts. Not share how it works exactly since the other extensions don't.

So helpful.

Incredible!

This extension is very useful - it enables setting a custom title bar specific to Firefox profiles.

In Linux/Plasma/KDE, the window titlebar colors can therefore be customized through matching the window title (Window Management --> Window Rules --> Window title Substring Match/ Appearance and fixes)

I'm afraind this addon's feature is not clearly described, as it can't 'modify' a window title, whereas can only adds a prefix to it.

Really nice for those like me who keep many windows open.

Does exactly as described. Super handy for someone like myself that works with a project per window.
