[PPC] Firefox 48?

Currently there is no FF 48 for Power BE platforms.

However, there is a way of enabling a major feature of 48 while using 47 - multiprocesses whice improves FF for me on my non 3D or 2D enabled installation (Southe Islands card):

"browser.tabs.remote.force-enable" => add a new boolean to about:config and give it the setting "true".

* SLIGHT WARNING *

Some older extensions that haven't been updated might have issues with this setting.
