The same happened to me with Firefox on OSX.  I've downgraded back to 
1.5.0.9 until a few of the extensions I use daily are updated.  If you 
decide to downgrade as well, you might have to manually re-enable the 
extensions in Firefox to get them working again.

I haven't updated Firefox on my Ubuntu install for this reason.

I also recently discovered that Thunderbird (on OSX anyway) has a 
default setting to automatically check for, download, and install 
updates without user confirmation.  Really made me mad when I saw it has 
updated itself without so much as a 'can I do this?' confirmation 
message...  I disabled this for the future in Thunderbird > Preferences 
 > Advanced > Update.
