there is a problem with Work Offline 2.0 Bewertet mit 5 von 5 Sternen

as someone below said i want to confirm that there is a problem or bug around "Work Offline 2.0" with Firefox.
I'm using Firefox 12,13,14 Final versions.
but first i installed "Work Offline 2.0" i couldn't see its icon on Firefox statusbar (add-on bar"

so i went to your troubleshooting Guide on your website and read it.
i notice i must chose "Work Offline" icon by customizing toolbar.
so i added it and anything is OK.
but there is a problem.
i can't replace work offline icon in firefox's statusbar (add-on bar" while by "Work Offline 1.6" i could do it easily without any problem.

so i decided to get back and use old version of "Work Offline 1.6"
please solve this issue in "Work Offline 2.0" and update it.

Thank You so much for this Add-on.
I love it.

Thank you for using my extension!
I know the problem and the problem is caused by add-on conflict,
but I can't find which add-on is in conflict with Work Offline.
Do you find the add-on?
