Before the latest versions of Tbird 76, if you made a mistake when entering a recipients address in the To: field, you could simply click on the To: address line and use the Backspace key etc. to correct it. Now you can click as much as you want and all you get is that the address is highlighted. This is so annoying. After entering an address, if you wanted to CC to someone, you simply pressed ENTER and it would open a second address line. Now it jumps to the Subject line. It would be logical to at least show a right-click option to add another address but no, now you have only Undo or Paste. The behaviour of the TAB key has also been changed. From the subject line, I want to use Tab ONCE to get into the next field - the body of the email. Instead it appears to tab through the "Variables v" and "Options v" menu names on the right and gawd knows where else, and it isn't until about 5-6 pressing of the TAB key that I finally get to the message body. What is the point of changing something that worked fine to something that requires more time-wasting key presses ? There are no options for changing the behaviour of the Enter or Tab keys in Tbird. Sadly, like everything else "improvements" seem to be steps backwards wasting the time of the user.

And on another note, the Crashes which have been occuring every time I try to add an attachment for the past 18 months, still happen... The only way I can add an attachment without Tbird crashing is by drag and drop.
