firefox resizing tabs when clicking to close

[adrianomartins1]

This has been a nuisance for a couple of months, out of nowhere a update change this behavior, every time i click on the close button on a tab it just resizes so i have to move my mouse to close it, you can imagine how annoying it can get after 2 or 3 tabs, and it happens at random, sometimes Firefox will not present this behavior, but it happens most of the time.

I agree. I believe Chrome has a behavior that Firefox should implement: when closing tabs (either by clicking the X or by middle-clicking anywhere on the tab) the tabs do not resize until a brief delay after the last tab is closed. This allows the user to rapidly close many tabs quickly: one tab closes, the rest slide down into the empty space, the next tab can be closed, etc.
