Sadly, it completely stopped working recently =/ I still hate Mozilla for revoking the possibilities this addon brought us.

I enjoyed tab mix plus for many years but find this pretty much useless. I hope in the future it brings back some old features, but at the moment it offers nothing to me.

So sad to down-rate this app!
I have loved this extension, and it's previous incarnations, for YEARS!
Firefox pays NO ATTENTION to the settings... Waterfox does MUCH better.
Keep up the good works, dev team! Hopefully, Firefox will get their sh-- together... someday...

UPDATE! 8-11-20
This doesn't seem to be working well in either firefox or waterfox. I'm so sad. There used to be a popup window with all these choices, but now it's a short page that doesn't seem to make a difference in either of my browsers.
I've loved this extension for years and every once in a while I'll get my old option window back, but I've recently switched laptops (hey, it could be the laptop - what do I know!) and it really isn't working for my browsers, right now. :(

Barely provides any functionality. There are a lot of APIS usable at the moment that are not being tackled. I don't know how many users really did use TMP for it's session manager capabilities but it seems the devs are focusing too much on that now and not providing other useful features that were and still are possible to translate to web extensions since the day quantum was released.

Leider nur in englisch und deshalb für mich nicht zu gebrauchen.
Habe versucht, durch "ergoogeln" die erforderlichen Einstellungen in about:config zu ändern. Für mich ohne Erfolg.
Ich warte, bis es auf deutsch kommt und mehr Funktionen beinhaltet. Wenn es "idiotensicher" und bestens funtioniert wie das alte TabMixPlus, bin ich dabei und werde auch dafür gerne zahlen / spenden!
2 Sterne gibt es von mir wegen der guten Absicht.
Viel Erfolg!

Messes with the function of the mouse buttons making them unusable. Left button opens a new tab. Mid click makes I don't know what. Etc.

On old Firefox, this was THE greatest addon. Firefox Quantum and it's bullshit system of web-extensions, has totally made it impossible for the Dev to retain functionality. All that's left is a pale shadow of the addon that it used to be. And even some of those features don't work.

Force to open in new tab (All Links) not working when opening a rss URL.
