This was a great add on before it quit working. PLEASE fix.

all of the sudden its not working. 5-6-2025

Doesn't work with the custom color. It always shows pink for me.

Suddenly started defaulting to Purple, and ignoring my browser setting. Might just have to write my own extension or hack Firefox (without this extension).

No longer works. Used to love this, but no longer works with newer Firefox versions. :( Hopefully the developer will fix it.

Also stopped working, didn't found any other way to report

Been using this for several years has now stopped working on Firefox and Firefox nightly.

Hello, I hope you are well? I love your addon, but for some time now it does not work. I always have to restart addon and then it works again.
Detailed error description:
I click on a link, the link colors in and then the link opens and I have visited the page.
Now I go back to the previous page and the link is not colored.
If I restart your addon in the addon settings it works again for a while. Do you know the problem, can it be solved? Thanks in advance for your effort.
Best regards,
Elena

For the life of me I cannot get this add-on to work. On previous versions of Firefox there was one that worked well. I conduct a heck of a lot of research and one of these highlighters would be great if it worked and would save me a lot of time.

Doesn't work at all. In Firefox preferences I set the visited link for red. Nothing. The links return to blue.
Firefox 78.1.0esr (64-bit)
2015 27" iMac

No configuration options whatsoever to be found, neither on the addons panel nor in any other icon.
The "default" color is some kind of dark purple, barely visible. Running FF 67.0.4.
Addon obviously deprecated, since it hasn´t been updated in more than 1.5 years.

The extension installs but the icon does not appear in the tool bar, hence, I can't access the tool. I'm using Firefox 63

Funzt nicht !!
