I use Mozilla Firefox because of the great tab control
, nice bookmarks toolbar, no text aliasing, other add-ons, and general speediness. But it slows down a lot
as I like to leave one window open for days (using Windows' hibernation function at night), which is annoying.
Firefox was originally supposed to be simple and fast, replacing the slow Mozilla suite
, but with spell-checking, RSS support, history caching
, etc. in the core instead of being relegated to add-ons, it's becoming increasingly heavy-weight. Inefficiencies in the code
don't help either, though changes will mess up the plugins people love, I hear.
