I've had readability bookmarked for a few weeks and have occasionally used it to combat bad design. Thing that bugs me is in FF I can't access the bookmarklet without using the bookmark menu or a bookmark bar. Just to clarify I access my bookmarks mainly through the awesome bar. I don't have the file menu displayed nor a bookmark bar visible - this makes it a bit of a pain.
I guess it's a FF bug that javascript bookmarks are not listed by awesomebar? Any suggestions?
