Apparently we break some FasterFox features
From a post to the HTTPS everywhere mailing list a while back:
It was recently discovered that two of the features of FastestFox, (awesomebar enhancement & linkify text urls(i haven't yet explored the problem with this specific feature, could be unrelated to https-everywhere)) were not working. A trial and error disabling of every addon present in the test system was done. It was* found that the awesomebar enhancement worked when https-everywhere was disabled*. FastestFox *does a google search as characters are typed into the Location Bar and lists the possible alternatives to the entered text. It is suspected that enforcement of https by the https-everywhere addon is the root of the problem
