Upstream rejected it. The extension included with beagle-0.3.5 and earlier was not fully compatible with firefox-3. beagle-0.3.6 later came out with a compatible extension. If ubuntu didnt change anything in the extensions then the extension would work fine as intended (i.e. pre-beagle-0.3.6 incompatible with firefox-3 and 0.3.6 and later is compatible).
