For me it worked fine too till FF45 Update came out. Could the author please patch this so it works again?

This review is for a previous version of the add-on (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.
