Clicking on the downward arrow at the right end of the location bar no longer displays the drop-down list of sites visited, bookmarks and addresses typed in location bar
Since I upgraded to Firefox version 3.6.10, clicking on the downward arrow at the right end of the location bar no longer displays the drop-down list of sites visited, bookmarks and addresses typed in location bar. My Tools > Options > privacy setting is to save history, and if I start typing a previously accessed website's address in the location bar, then the full address appears as a drop-down item. But not when I just click at the right end of the bar.
Make sure that the Location Bar is not set to "Nothing": Tools > Options > Privacy > Location Bar: When using the location bar, suggest: History,Bookmarks,History and Bookmarks
Yes, it's already set to History and Bookmarks, and Firefox has already stored many bookmarks and history items (When I begin typing an address in the location bar, it displays the full address - which indicates it's there in history)
You can try "Reset all user preferences to Firefox defaults" on the Diagnose Firefox issues using Troubleshoot Mode start window.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
