I uploaded a video to Viddler and mistakenly pasted the video URL into the tags field. When I went to delete this tag by clicking the (x) next to the tag, I realized the (x) was not there. Because of the length of the tag, the (x) did not display.

There was two ways I could think of to fix this problem. 1. Modify the AJAX in flight and use another tags delete function to delete the tag I wanted to remove (tested, works) or the simple way:

In FireFox open Firebug, inspect the div around the tags (id=smTags), Modify the text size from 90% to something smaller, click the x next to the tag you want to remove, confirm you want to delete the tag, and finally refresh the page. Simple.
