Worked fine for me until FF 45. If I am not mistaken the author is not supporting its development anymore. Anyone knows any alternatives?

Dié resensie is oor 'n vorige weergawe van dié byvoeging (1.7.5.1-signed).

This bug should be fixed in 1.7.6 version, released now.
A workaround is to set the preference "extensions.profileswitcher.use_onbeforeunload" to false, but I suggest to try before the new version.

I'm still supporting the development, because this extension is for Thunderbird too, of course when XPCOM/XUL will be dropped support for Firefox will end.
