Ok but... Rated 1 out of 5 stars
This has the potential to be a great little piece of software.
Get RS Links works great for a whole bloody page!
If you only want to check let say 10 links on a page of 400, you CAN NOT do it with this extension even though the right-click context menu shows "check selected links" it just doesn't work. That is the ONLY reason why I would have this add-on. Too bad!
