I'd installed Firefox Beta from the third phase of beta, b3. and everytime that mozilla reaseled new updates, I could download and install them using
sudo add-apt-repository ppa:mozillateam/firefox-next Terminal command. but from the 5th. phase of beta version, i wasn't able to upgrade my firefox to the newer version until today, mozilla released 8.0 Beta 6. But i was able before.
What's wrong ?
and also, I'm a bit new to ubuntu and linux, if I can't upgrade Firefox beta from PPA, would you be kind enough to tell me how to install Firefox manually and loose nothing such as addons and history , as easy as a newbie ? :)
