Great but doesn't work framed websites (FF60.0.1)
and I want a white list option too.

Works great in Firefox Quantum v60.
I went to tools >>options >>fonts & colors >>colors and selected 'red' as the 'visited link' color..... works great.
Thanks for making something that should be a basic-level function of ANY browser.

Working great in FF60 Beta!

Very good with Unmht,Webpage Editable Switch ( удаляло любой контент),NoScript, Super Start, Tab Groups, EscCloseTab, Print Friendly & PDF, YouTube Video and Audio Downloader,Tab Mix Plus.

Really useful extension. Thanks for that!

Funzt nicht !!

Please add a white list option,because some paticular page doesn't need this function,thx!

Where the heck can I donate to the developer?? So useful little thingy.

The only downside in this version after FF57 came is that there's no option to switch off or list a websites where I don't want to use Visited. Please get that option back and it's 5 stars as before.
