When downloading a file, the option "save as type" is greyed out. This doesn't happen with Chrome. Browser resting worked for few downloads only.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

It is possible that (anti-virus) security software is causing the problem. Try to disable security software temporarily to see if that makes a difference.
