For accessability reasons, I use macros that press Custom buttons on the Navigation bar based on Relative Window position.
Firefox 184.108.40.206's inconsiderate size changes to this toolbar threw-off the relative window positions and caused my macros to press the wrong button.
Thanks to Classic (Small) Toolbar Buttons 1.1.2 I have my larger buttons back.
Only suggestion I can make is in the name. I don't use the Small Toolbar buttons, but the default (larger) one.
Lets hope Firefox Devs. doesn't find a way to break this necessary add-on!
I know the name might be misguiding, but when this extension was released, it only covered small buttons. Back then on Firefox 8 large button were OK.
