hello, can you try to replicate this behaviour when you launch firefox in safe mode once like described under: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Separate issue;

Update your Shockwave Flash v14.0 r0 http://get.adobe.com/shockwave/ The link for Flash Player v14.0.0.179 http://get.adobe.com/flashplayer/

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

See:

• https://support.mozilla.org/kb/Server+not+found
• https://support.mozilla.org/kb/Firewalls

You can try start Firefox in Safe Mode by holding down the Shift/Options key.

This helped. "Uncheck Use hardware acceleration when available."

Thank you. :)

thanks for reporting back. one final favour: you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? maybe this might give us a clue what is going on to help other affected users. thank you!

thanks - does the same thing happen when you update your intel graphic drivers to the newest version available for your system?: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23764

Dont know. Will have to check that.
