Lock (not pin) a tab group

[Kerio]

Hi,

I'd like a right click on a tab group name to lock/unlock the group so i can't remove or add a tab from it by accident.

Or basically the opposite of "right clic => dissociate", "right clic => keep associated untill i say otherwise".

Or the same behaviour than when you slide a tab into a group, you see the color bar, you let it go and it's added. I don't want to remove it by sliding out for 1/100th of a second...

By accident i mean Firefox behaviour is really really crap, many time i click on a tab inside a group (especially the rightest one) and notice later that the tab isn't in his group anymore...
