Want to tweak how Firefox’s default search options react to you in the browser? The SearchLoad Options extension should do the trick then.
Options include clearing the searchbar and resetting the search engine after each search. A time delay can be set in order to reuse search strings or search engines before changing the state of the searchbar.
Search results can be loaded into the active tab, a new tab, or a new background tab. An option allows new tabs to be created regardless of whether the current tab is blank. New tabs can also be created by using the Alt key.

Merge MySpace and Firefox
Do you want to bring together the best of MySpace and Firefox? Sure Firefox is sleek and nice and MySpace is about as pretty as that Hungarian transfer student that wanted to take you to your prom. That doesn’t mean they can not get along though. The best tool to gain access to MySpace that I have ever found is the unofficial MySpace Toolbar.
One new feature they have added is notifications when important things happen. You know, like when that friend of yours posts the 101 reasons why you shouldn’t use your toes to pick your nose.. or something to that effect.
