Icons for different add-on keep disappearing from my toolbar and from my status-bar, like toolbar buttons, update scanner, and yahoo mail notifier. These add-on are suppose to be compatible with FireFox 3.5. The only way I can seem to get them back is to reinstall the add-on, which dose not work all the time.

Reproducible: Always

I am getting the same problem. I have to reinstall the add-ons as well. Maybe the beswt thing to do is remove version 3.5 and go back to version 2.

There is an additional related problem with 3.5.x
If you close Firefox with >3 windows open, upon restart, only the first opened 3 windows have all of the status bar icons
The rest have none (see attached image)
Opening new windows restores the icons

100% reproducible

Legacy extensions are no longer valid in Firefox 57, closing.
