Frustration Rated 4 out of 5 stars
Why do all the best extensions get abandoned while the rubbish ones (or the ones that have hundreds of similar alternatives) carry on being developed?
There is NO other extension that performs this function (all the others only do temporary renames that don't last between sessions) so I have no choice but to carry on using TabRenamizer even though it has a problem that annoyingly causes the loss of tab icons from unfocussed tabs.
If it were not for this one bug, then this extension would be absolutely perfect.
Another indispensable feature bites the dust.
