I don't understand, Firefox is a great browser, but the location bar is so slow. It literally was stuck for 30 seconds looking up something in its database.

Is there a way to tell it to stop trying to be so smart about matching URLs?

(Edit: is there a way to limit the history so it purges old pages that have only been visited once, but it keeps pages that were visited multiple times?)

You might find a couple of tips here Firefox 3.5 Slow and Hangs After Typing a Few Letters in URL Location Bar around cleaning out your SQLLite places database.

Vacuum it!

There's an add-on to this automatically as well.

Since Firefox 3.0, bookmarks, history and most storage is kept in SQLite databases. Also, the default history time span was raised from 9 to 90 days as it became more discoverable and useful thanks to the awesome bar, so depending on your browsing habits it could represent some pretty large databases.

Aas any other database, SQLite databases become fragmented over time and empty spaces appear all around. But, since there are no managing processes checking and optimizing the database, these factors eventually result in a performance hit. So, a good way to improve startup and some other bookmarks and history related tasks is to defragment and trim unused space from these databases.

about:config

browser.urlbar.maxRichResults

Set that to 0 and it'll stop searching (Or just set it lower and see if you can't get better performance out of it)

It's searching a HUGE database if it's taking 30 seconds, have you considered reducing your history length?

Not necessarily a huge database. I've seen performance to be pretty crappy on numerous systems already, sometimes even after a fresh install of FF. –  Joey Oct 27 '09 at 13:43
    
Huh, maybe I'm just lucky? Searches still only take a few seconds and I have a good few months of hard browsing in there. –  Phoshi Oct 27 '09 at 13:45
    
Turning off a (quite imporant) feature people use non-stop because it hogs the CPU is a silly way to go about it: the right way is to report bugs. –  Tomislav Nakic-Alfirevic Jun 20 '10 at 16:39

If you have installed the extension "speed dial", you should try to deactivate it because it adds a massive lag while typing in the address bar or search bar.
