Cannot remove autocomplete entry from address bar; have already cleared history, and entry is not in the drop-down menu of the address bar either.

Question

I am having problems removing an autocomplete entry from my address bar; I have tried clearing my history, so it's no longer in that, and I do not have it bookmarked either, so it's not getting the URL from that location either. The autocomplete entry isn't even showing up in the drop down menu, so I can't even scroll through that to delete it.
Basically, I want to be able to type "st" and go to "store.steampowered.com"; however, despite numerous times of typing in "st" and then going down into the drop-down menu to choose "store.steampowered.com", the bar continues to autocomplete "steamtrades.com", which is exceptionally annoying because I do not have that website bookmarked, or in my history, yet it continues to autocomplete to that address, which I do not want it to autocomplete to, and cannot figure out how to remove because I've already cleared my history multiple times, do not have it bookmarked, and it is not showing up in the drop down of the address bar for me to go down and force delete it.

Answer 1

Did you try to remove some letters from steamtrades.com to see if that bring this entry up in the drop-down list?
If it is not in the history then it might be present with a typed=1 flag indicating that you have typed or pasted it in the location bar.
You can use the SQLite Manager extension in Firefox to inspect the places.sqlite file to see if this entry comes up in the moz_places table.
