Pale Moon?
Lost patience with FF ages ago.
I just like Palemoon better.
Not even for any good reason, though I think I did have some at the time.
EDIT
Just fired up FF. There are loads of plugins I'd never knowingly use. (Silverlight anyone).But some I'd miss.
VLC, PDF-Xchange viewer, Google Earth.
Which are the only ones I also have on Pale Moon btw.
