As a Firefox user since v1 on Linux I have witnessed how slow some parts of the browser has become. For instance, textarea text typing can be so painfully slow with a visible lag between keystrokes.. that's not just on a certain websites and with spell-checking enabled, but with all options off on a blank page with single textarea element.. I guess there is no way to get rid of all the bloat of the ages..
