Why do all the unused icons appear in a box on the navigation bar after I download a file?
Since the last Firefox upgrade last week a large box of all the unused icons appears on the navigation bar after I download a file. If I click on this box, the previous download information appears. The icons in the box aren't useable. This box doesn't appear when I first open Firefox. The box is so big it crowds out the other items in the navigation bar. Any ideas?

This issue is caused by a broken extension that isn't working properly and that doesn't support the current Firefox release.
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.
In my case, the problem extention was "RSS Icon"
