I'm using FF 20.0.1. The downloads icon does not display on my toolbar, I can activate it by clicking on the empty space, but the icon is invisible.
Also when I select "customize" for the toolbar, the icon appears, but when I leave "customize" the icon disappears once more.

Starting once in Safe Mode may have caused Firefox to recreate a new localstore.rdf file that worked.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

You can also check for problems with the localstore.rdf file.

I restarted FF in safe mode and the icon appeared. I then restarted FF to see about selectively shutting down add-ons to see if I could narrow down the problem. When I restarted FF the download icon was visible, although I didn't make any changes.
