I installed Mageia 5 on a new hard drive and when I copied my old .thunderbird folder over, Thunderbird started but could not read my address book. All of my saved local files are there. Each time Thunderbird started, it appeared to be checking for compatibility and said: Unable to load address book file abook.mab. It may be read-only, or locked by another application. Please try again later.

It turned out to be a permissions problem for abook.mab and history.mab - somehow these files were read only for user and when I added write for user, the address book information was available. It still does the compatibility check each time so suspecting that permissions could be the problem with that, I added user write to compatibility.ini but Thunderbird still checks for compatibility each time it starts. On another computer I installed Mageia 5 and migrated .thunderbird, it does not do this so I suspect this isn't the usual behavior. I wondered if anyone knew if there may be another file I need to look at permissions that may be incorrectly set.
Thanks.
