Flagfox 5 beta 3 is now available for testing. You can download it from the Flagfox versions page on Mozilla Addons. If you have Flagfox 5.0b1 or 5.0b2 installed you should get an automatic update at some point to 5.0b3. (this update does not yet affect stable Flagfox 4.2.x users)
Firefox addon updates can also be checked for manually via Tools / Firefox button -> Add-ons -> click options icon (to the left of the search box) -> “Check for Updates”.
Changelog for Flagfox 5.0b3 (since 5.0b2):
- Fixed locale file loading to bypass the unreliable string bundle cache on update
- Some more locale updates and the addition of a Malaysian locale
- A few more flag icon updates
