M17 has a nice feature when opening several browser windows. URL's visited with one browser window will automatically get the "visited" color in all other browser windows when the mouse moves over it. This is very useful when reading mailinglist archives keeping the index in one window and messages in another, and using the "next thread" links in the message window. Messages read via "thread next" will then show up as "read" in the index before I waste time clicking on them. Unfortunately, this don't work in any of the post-M17 nightly builds. Moving the mouse over url's do nothing, I have to reload the index page. Network io takes unknown time, and then I'm hit by the "long text pages take long to render"-bug.

dup of 48578: visited links don´t change color after opening in new window *** This bug has been marked as a duplicate of 48578 ***

VERIFIED Dupe
