After a reboot, why are most of my addons are deleted?

more options

This is only happening since 33.1, but I can't spot any instances of others having this trouble. Each time I restart the PC, most of my addons are deleted. A few remain, and the ones that aren't deleted are always the same. This is isolated to my desktop, but doesn't occur on my laptop (both 33.1 with Windows 7 Ultimate). There are no recent crash reports.

Always remain: - Adlock Plus - Bazzacuda Image Saver Plus

Deleted after reboot: - BetterTTV - img2tab - Keyword Search - Reddit Enhancement Suite - YouTube Center

Any help would be greatly appreciated.

Firefox doesn't make any configuration changes at Windows startup, although its background service may check for updates.

There are other programs that may do a little browser cleanup at Windows startup, including CCleaner. I haven't previously heard of losing extensions, but if you use CCleaner or a similar browser privacy tool, you might want to try deactivating it as a test to see whether that works around this issue.
