Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.3a5pre) Gecko/20100424 Minefield/3.7a5pre ID:20100424030253 Since bug 480350 landed, the autocomplete dropdown sometimes shows more items than the limit defined by browser.urlbar.maxRichResults, probably because of the extra entries generated for "switch to tab". This seems to depend on in what chunks the entries are added, since I do not see this consistently. steps to reproduce: 1. create new profile and start with that profile firefox loads http://www.mozilla.org/projects/firefox/prerelease.html 2. open new tab, go to about:config, set browser.urlbar.maxRichResults to 4 3. close the tab containing about:config 4. open new tab, load http://planet.mozilla.org 5. open new tab, type p into location bar expected results: autocomplete dropdown with max 4 items actual results: autocomplete dropdown with 5 (or sometimes 6) items

This should be fixed by bug 564573. Please reopen if not.
