Z 3 z 5 gwězdkow pógódnośony

Thanks Paolo for looking into this.
I installed the latest version 1.7.5.1 but it still didn't fix the problem.
I then went to about:config and changed the property of "extensions.profileswitcher.use_onbeforeunload" to false in all the profiles I have created and I can finally switch between them again.

Toś to pógódnośenje jo za pjerwjejšnu wersiju dodanka (1.7.5.1-signed).  Toś ten wužywaŕ ma starše pógódnośenje toś togo dodanka.

Install the 1.7.6.1 when it will be approved by AMO and try to revert that preference to true, it should work as expected
