Option to prevent 'opening' multiple emails in Thunderbird

[GaryT]

Would it be possible to have an option to stop Thunderbird 'opening' more than one email? Or at least stop it happening on a double click or 'enter'?

This is something I never want to to, and end up frequently doing unintentionally.

I often select multiple emails, e.g. to delete, move, or mark, and I sometimes end up with them all opening in separate tabs or windows. 

This is possibly partly due to an old mouse that generates unintended double clicks when I click an email to add. It's also possibly partly due to my Parkinson's.

The consequence of this can be painful if I've selected dozens of emails. Thunderbird grinds to a halt, and getting rid of all the tabs can be a little time-consuming as I have to either individually delete them, or 'close other', and restore the tabs I want.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Thanks for the idea. I don't think we would implement a new feature based on solving for bad hardware.

But there is ability to have the double click open in an existing message window, rather than create a new one.
