It works fine on Pale Moon 64-bit version for Linux as well. All tabs are restored after restart.
I don't like the button it uses, however; it won't use the restart button provided by my theme (Red Cats). So use it in conjunction with Restart App Button 126.96.36.199-signed by Button Guy, which lets me use my theme's button, but lacks the shortcut keys. I set Button Guy's Restart App Button not to appear in the pull-down menu; I set Schuzak's Restart to appear in pull-down menu, but I remove the button. It would be nice if Schuzack could change his extension so it would use my theme's button, then I wouldn't need the other extension at all.
