I'm so annoyed of having to re-install my Extensions when there is a new FFP release, is there an easier way? thanks

Since 1.5.0.5, you can do in-place upgrades. What this means is that you can install a new version right over an old version, replacing any files that already exit. All your settings, extensions, bookmarks, etc are preserved. It's mentioned on the support page (the first place to check for questions):

All the apps here now support in-place upgrades.
Sometimes, the impossible can become possible, if you're awesome!
