I installed "Restart Browser" expecting a simple, convenient way to restart Firefox with a button click. Unfortunately, the add-on falls short. There is no button added to the Firefox menu, which is the main reason I got it in the first place. The only "button" available is buried in the add-on's options, and when you do find it, it does absolutely nothing! I tried restarting Firefox multiple times and even reinstalled the add-on to see if it would fix the issue, but no luck.

Overall, this add-on does not work as advertised, making it completely useless. Save yourself the hassle and look elsewhere.

Doesnt add a button really, adds a tab with a button on that page. Needs to be a button on the tool bar to be functional

Не работает. Удалите уже это отседа. Перезапуск браузера — фиктивный.

had to uninstall, because any benefit this plugin has is negated by constantly spamming the authors site on EVERY little update!

This doesn't restart the browser itself, but closes all tabs and opens them again

Everytime Firefox updates, this add-on loads some ridiculous page and also gives you a toast message near the taskbar asking for donations. Uninstall.

Не работает. Не только не перезапускает браузер, но еще и уничтожает сессию, сбрасывает открытые окна и вкладки. FF94

Damned CRAP!! RARELY Works.

This addon doesn't work properly - the tabs opened after restart are (very) different.
Also - and this is really bad - here is the list of permissions used. How can this be justified.

Access your data for all websites
Exchange messages with programs other than Firefox
Display notifications to you
Access browser tabs
Access browser activity during navigation

I don't know who Nacho Vázquez is, but judging by that list I don't trust him.
I'm about to uninstall, but I will repeat the tip given by mjjordan :
If you want a TRUE Firefox restart IN TWO CLICKS, do this:
1) Type about:restartrequired in your browser
2) Drag and drop that page to your toolbar
3) Click "Restart"

This addon does not restart the browser.

All I want is for this add-on to quit and start Firefox This add-on fails spectacularly in that respect.

The author of this crappy extension is either a jerk or a con artist, as it doen't work at all, but make you go through a bunch of weird headaches. I wish I could give it 0 star. Stay away, it does not restart, and it's the worst extension ever in FF!!!

This does not "Restart" browser it merely "Refreshes" browser. There is a big difference.

再起動しません。
Do not restart

Stop looking for the Holy Grail of a usable restart button - they don't want you to have it !
BUT USE THIS INSTEAD : If you want a TRUE Firefox restart IN TWO CLICKS, do this:
1) Type about:restartrequired in your browser
2) Drag and drop that page to your toolbar
3) Click "Restart"
Done!
All credit to Andorio2007 - brilliant ! It works - no messing !

did not work FF 75.0 all I want is a button to click to restart browser and start with same tabs loaded like old firefox/waterfox/palemoon restart addon used to do. something simple, click a button/menu item and FF restarted.

Not working, I click on the icon and a message appears saying that there is no saved session

If you want a TRUE Firefox restart IN TWO CLICKS, do this:
1) Type about:restartrequired in your browser
2) Drag and drop that page to your toolbar
3) Click "Restart"
Done!
