Great Addon. Should be installed on every Firefox Browser.

very helpful, especially for articles you've read but can't remember if you did so

I used grey visited links in old firefox and coudn't find it again in my new install and found visited link enabler.
Today i found it and also this great addon.

This is really great.
Thank you very much.

=====================

Four Addons like this that are really great for research:

1. Visited link enabler
2. Gray visited links (use either this or that!)
3. Highlight bookmarks
4. Last visited Toolip (This Addon)
