You make a good point - my Firefox keeps crashing as well and come to think of it, it did start at the same time as Gmail making its changes.

As my browser crashed whilst sending a post and on the laptop firefox crashed whilst doing nothing, I've changed my language to English (UK), just need to remember that it's Deleted Items and not Trash now.

same stuff here. crashing often when clicking on tabs

Seems like it doesn't like almost every Firefox plugin, including the HTML Validator.

same problems here, when I try to reply on an e-mail just nothing happens, when I go back to the inbox it asks if I'm sure and that the message will not be send

why change anything that isn't broken
