It seems like the webbrowser (5 questions) tag needs to be merged into and become synonymous with browser (702 questions) (per the definition of the latter tag). I'd do it manually, but I can't suggest a synonym. Thanks!
updating post history, 5 rows affected updating posts, 5 rows affected updating PostTags associations, 3 rows affected removing/renaming old tag, 1 rows affected updating count for master tag, 1 rows affected tag remapping of [browser] and [webbrowser] complete! Deleting Synonym browser -> webbrowser Tag Synonym webbrowser -> browser was approved!
Thanks for the heads-up.
