Finally an extension that can change the color of visited links in Firefox version 138.
However, I can't see the menu that appears in the image, how do I access it?
For now the color of visited links is "red", how could I change it?
Thanks a lot
Update: The author kindly answered my question and explained how to get to the settings (extensions icon>gear icon>add to toolbar). Now I can say that this extension is rally awesome. Thanks really a lot, I'm sorry I can't add more stars.

Needs updating. For some reason it no longer works on visited Youtube videos, which was the main thing I used it for. This is basically the only extension that includes a blacklist, which is incredible. As soon as it's updated, it's 5 stars.

doesn't work on firefox v.78. Looks like the author of this extension hasn't updated it in awhile. Look elsewhere. If anybody knows of an extension that changes visited link colors, and it works on the latest browser, let me know!

I wanted to install your extension on a second computer with its configuration through firefox account synchronization, but although it is true that it has installed it, it has not saved the history of links that I have visited and I do not know which ones I have visited. Do I have to copy any file from the first computer or do something else? I really like your extension.
Sorry if there is something you do not understand is a translation of google Spanish-English

On Reddit color scheme is totally wrong. Visited links are light gray, but comments and posting time are light red (color I setup for visited links)

Works great! Nice to have opt in functionality now :)

Saw your post on reddit. Nice work, I'd give 5-stars for as long as it works fine on my Firefox browser :)

Magnifica extension, excelente funcionamiento. Perfecta es lo que se busca cuando se instala. Enhorabuena y muchas gracias por un buen trabajo que facilita enormenente el mio

Not work in my Firefox 66.0.3
