Firefox shows already visited websites as a purple (instead of blue) link.
This is very useful, but how to "reset" so that everything is shown in blue again?
I don't want to reset anything else. In particular, I would be glad to keep my passwords, cookies, and URL autocomplete data, if possible.
Context: I have a page full of links that I must all open one-by-one, and the color helps me track of my progression. Unfortunately when they are all purple already it does not help anymore, so I want to reset that.
Using Firefox 50.1.0 on Linux, if that matters.
