I'm running into a strange issue where the location/awesome bar still autocompletes domain names for items in my bookmarks despite clearing all history and setting the privacy setting to only suggest history. Initial settings: Privacy > Location Bar > When using the location bar, suggest: History Steps to replicate: 1. Bookmark something, for example, a youtube video. 2. Clear History (Everything, all options) 3. Close firefox completely and re-open 4. Visit the bookmark and for good measure, click a few other links on the site 5. Repeat steps 2 and 3 6. If your bookmark was a youtube video, simply typing 'y' into the location bar should suggest/autocomplete the domain 'youtube.com' I've tested this with multiple sites and multiple version of FF on different operating systems. The only way to remove these autocomplete entries is to delete places.sqlite. I understand that I can change the Location Bar to suggest nothing in the Privacy settings, but I actually do want it to suggest history. I just want to disable what is causing the permanent, undeletable, error entries.
