Vista - Mozilla Problem!

Hello,

when i open my mozilla firefox browser a message comes up that says,
(this message comes up in greek so the translation is mine)

''weakness at initializing the security components of this application. There is a problem with the files at the security catalog of this application. Please check that this catalog doesn't have any right restrictions in reading.''

then i press ok and mozilla opens, but lots of stuff don't work like i can't bookmark anything or my favorites are all gone and others. I unistalled it and installed it again but its the same. i even installed it at another place/?path? but still the same.

Any ideas? Thanks a lot!

Do you run Zone Alarm by any chance. I had real problems with FF until I removed ZA and replaced it with Kapersky.
