When I go to do a "save as" in Firefox after running CCleaner, the file pull down has not been completely cleaned. I noticed this in CCleaner / Free and so I tried upgrading and now it still leaves 1 or two filenames in the list.
Firefox 57.0.2
Windows 10 Home v. 1709 bld 16299.125
starting with version 5.23, and continuing with 24, and 25, the program stalls at IE history. On version 25, it got a little better, but it still is more than a minute.
Windows version: 7
