Can you reproduce on a clean profile?

Did you file a bug?

Using a new clean profile does prevent that strange behavior of Firefox, but I'm still curious about the reason

You probably have a corrupt places.db.

Doesn't the star next to each entry mean it is in your bookmarks somewhere?

Yes, but it's the "linkedin.com" autocomplete he's referring to, since it doesn't show up in any bookmarks (or nonexistent history)

Admittedly it wasn't a very clear article, and probably took longer to write than the bug request would have taken to submit. :/

Everything screenshot I saw seems to have stars next to it (even the linkedin one he posted). These starred bookmarks need to be cleared by going to Bookmarks, Show all Bookmarks, then heading to the starred bookmark section and wiping them out from there.

In the location bar, arrow down to the entries you want and then hit delete (or shift delete?) and it should clear them.

It was strange that the suggested address was not in the dropdown list, so I could not delete it.

Kind of not the point though.

I'm sorry if anyone cannot access my blog. My host runs out of resource. I will post some screenshots here

Here are the screenshots https://www.mediafire.com/folder/mbb06f6ru4ovo/Firefox

I tried every possible way that I could think of: - Clean up history - Clear cache - Disable addons - Enter private mode - Disconnect Firefox account - I also tried turning off cookies

As you can see, Firefox still suggests a website that is not in my Bookmarks (I don't have reddit.com or any of its child page in my bookmarks). I also want to note that not only the address bar, but also the fields (username & password) of some sites that I bookmarked are still stored after I cleaned up everything.

p/s: I haven't tried creating a new profile. Let's see.

Search suggestions?

It was turned off too

If you have nothing to hide it doesn't matter.

He's trying to hide his surprise gift to his wife. Or something.

I google stuff my co-workers find funny but my boss doesn't.

To clear space H.D.D space? Who are you to say the feature doesn't matter?
