I'm using Firefox Portable. For some reason, in text fields, firefox will randomly "paste" (for lack of a better term) the localhost into a text field and act like it's pressed enter. It can occur when I'm changing tabs, typing, and occasionally when I'm doing nothing at all. Is there any way to stop this? I've updated the software and tried reinstalling. I don't have any extensions or anything added to the base install. It happens randomly, but more and more frequently. These are new Windows 10 computers (mostly Panasonic FZ-55s, some Dell Toughbook models), and I can't find anything on them that would be causing this issue. Any help would be greatly appreciated.
