On Android PM reopens a closed tab

[NeverDidIt]

BUMP. Does no one have a solution? It is very annoying.

Hi guys,

Just to say I would be sad if PM Android were to be discontinued.

Here's the problem I'd like to fix. Whenever I return to PM, it systematically reopens a tab I have closed. This could be a security risk. How do I stop it doing that?
