Just did a [clean uninstall][] of ff0.93 (great article) and installed [ff1.0pr][]. It seems to run faster than 0.93 did. Also that fixed my shockwave problems.

More tips, [here's][] a good set of [adblock][] filters to get rid of most banner ads.

Now I’m looking into some bookmark manangement extensions like [del.icio.us][].

del.icio.us is a social bookmarks manager. It allows you to easily add sites you like to your personal collection of links, to categorize those sites with keywords, and to share your collection not only between your own browsers and machines, but also with others.
This extension integrates del.icio.us with Firefox.
