My request relates to losing work from accidentally clicking on the ‘x’ in a Private tab, a misfortune one can easily experience with a crowded tab bar.
I confess to almost always having too many tabs open in browser windows. The knock on effect is a reduction, often a significant one, in visual clarity in the tab bar.
However, since I find that there is no cure for that in my case, I would greatly appreciate a 15-20 second grace period for recovering a mistakenly closed Private tab, allowing it to be restored within that period of time before all is lost.
