Adblock Plus için Element Hiding helper <--remove this
BetterPrivacy <--remove this
Flash Block (Plus) <--remove this
You can simply disable Flash in the addons manager, and my thoughts are AdBlock for Firefox blocks FlashPlayer.
Ramblock <-- not finding any good information related to this plugin
Restart <--should be able to manually restart Firefox on command
Time Restart <--I personally think this is unnecessary, should be able to restart when needed and not setup to a time you think it's needed.
Microsoft.Net Framework Asistant(disabled)<--leave alone
it's also possible that Mozilla is blocking the .NET plugin due to pretty serious security exploits out there.

Have you tried to disable any antivirus/firewall temporarily

What happens if you try a different browser?
