I'm not sure who to tag with this bug, but it's awful.
As of today, if you edit a blogger post with embedded bullets using Firefox the HTML is scrambled. The tags for an unordered list are replaced with dozens of [font] and [span] tags, which in turn produce html errors. You can't save your work until you manually clear out all the bad tags.
On the one hand I've seen enough problems with Blogger that I've come to think of it as the black sheep of the Google family, but on the other hand Firefox 1.5 has more than its share of bugs. A pox on both their houses!
