I thought this had disappeared years ago so I wasn't expecting to find a working version. Perfect - thank you.

It simply has no effect for my browser. I like the features it claims to have but nothing actually happens regardless of which setting I toggle or leave as default..

Does exactly what it says it will. Works right out of the box. Could not be simpler.

Does not work

i like that extrension especially choosin custom colors for visited links and exeptions :)

I've created a simple local html file with anchors to a few thousand links I want visited.
Toggle Visited Status works,
Mark (all, selected) Link as Visited does not work.

Works as described. Ability to do all links, some links or one link on a page is great. Allows me to update links on pages with file lists of 10's of links every month.

WORK
BUT!!!!!!!!!!!!!!

if i paste bunch of urls into textarea(simple html i created) then highlight it and mark visited.....nothing work

Works as intended. Thanks for creating this.

!!! EXCELLENT !!!
Works very well (except when wanting to mark all links as unvisited).

For those who have problems, check the about:config page if the line:
"layout.css.visited_links_enabled"
is set to true. If not, change it.

MESSAGE TO THE DEVELOPER
I don't understand this part:
"Preferences are stored in the browsers local storage unless the browser sync storage is enabled for web extensions.
To enable browser sync storage set webextensions.storage.sync.enabled to true in about:config"

Why do we need to enable: "webextensions.storage.sync.enabled" to true?? If I we don't do it then what??

this is truly awesome. didn't think there is a smart WE in matter of link marking.
small tips:
→suggest in prefs that color value is hex
→let us hide it from right click menu
→stay awesome

It just does not work. I right click on a visited link that is purple & toggle the status & it remains purple. Closing out Firefox & restarting FF makes no difference.

FWIW my privacy settings are set to "Remember my browsing and download history", and the about:config option layout.css.visited_links_enabled is set to true.

I am using FF 57.0.4


Not sure how to reply to the developer's response so I'll edit the review.

It doesn’t seem to matter what link I try to un-visit, from either a Google search or a forum.

I just Googled “Office Libre” & this was one of the results.
https://www.libreoffice.org/download/libreoffice-fresh/?version=5.0.0

Right clicking & toggling does nothing.

Yet I can go into Firefox History & select that link & use the delete key on the keyboard & the link then turns back to blue.

This is an update to my original review made on Oct 11, 2017 (I could not find a way to edit it): After using this add-on for a while now, I still find it amazing and works as it should. The only thing I am finding is that every time I start Firefox, my option settings are gone, and I have to reset them. Every time. Hopefully, this will be corrected.

In this update (v5), marking all links as visited takes too much time. Example is one page of Indeed.com searches (50 results per page), and no other addons present. What took the previous version roughly 10 seconds per page, takes this version 1 min 35 sec. to mark all 50 links as visited.
