Great add-on ! But unfortunately, it does not keep saved the settings when Firefox is closed (returning every time to "Méthode 1"). Any suggestion? Thanks. :-)

Works fine, but why is so so so ugly?

This thing does not actually restart your browser. It just closes and reopens all the tabs. Which means its basically useless for all cases where your browser process misbehaves and needs a restart.
The name is a lie.
What it's worse - it can not do the single one thing people actually want - activate the already browser-built-in restart function. Instead it gives you a steaming sh*pile of BS functions nobody needs, and which I never even tried.

@developer: Defaults are everything. In default mode this thing is useless. End of story. If you want to make it useful, put a restart option into the file menu, next to exit, and have it activate the browser restart function. Also make this default for your toolbar button.

With version 67+ it doesn't work properly, it forces you to make the initial settings every time on method 1, too many clicks to restore or save the session first .... in short, once it was a good addon now it has lost its effectiveness in terms of practicality and time.

After every update an annoying message you have to click away. Donate for such a simple add on? Ridiculous.
