How to add more domains?

Does what it says... Change the color for visited links...

Tried this on v.88.0.1 and nothing. To eliminate any possibility for interference, I made it the only extension in Private mode and still nothing.

Installed this on the latest version of Firefox (74.0). Set the "change" color to red. It does not change a link color after I visit a web page. ?????

Allows you to change the color of visited links on Google search pages without affecting other sites.

Works great on Firefox 67.0.2. I can finally distinguish the visited links color in Google Search! Love that I can set it to any color/tone I want. Unlike some other add-ons I've tried, this one does not mess up other web page colors and graphics. Perfect.

Wonderful. This FINALLY fixed my problem of not being able to tell the difference between blue and purple on visited links. Nothing else worked without messing up lots of other stuff. However, now Firefox has refused to let this add on run and says it needs a new signed add on before I can use it. I can't figure out how to contact iBoonie so hopefully they will see this and get this issue updated/fixed so firefox will let it run. Thank you for this great add-on

I could not get Visitedlinkenabler to work, but this worked instantly. It was set at a bright red. I changed it to a less distracting darker red. Works fine so far with 60.0.2 (64 bit).

Дуже гарно зроблено, зручно і удобно!!!

Loved it (five stars) until it began crapping out intermittently (3 stars), now it has stopped functioning altogether (1 star).

Firefox 58.0.2 (64-bit), work super, thank's!

You have to use Google's own web site to initiate a search.

No funciona en mi Firefox 56.0.2 64bits

It works perfect. It would be nice if this works also on visited Links on other sites.

Does exactly what it says it would. Firefox 57.
