There have been reports of users losing all their Gmail while using Firefox. This is an interesting issue when it comes to webmail and the repercussions of using a centralized service.

It's an unfortunate fact that there isn't a way to backup your Gmail like you can your Yahoo Mail. One has to wonder why people would use a service that didn't offer backup.

Then again, how many of us actually backup on a regular basis?

What I can tell you is that Google did a good job responding to the issue and trying to fix it for the people affected.
