Thank you for your useful reply. But same problem occurring in http://www.indigenoustour.com/

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.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works better then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

You can also try to reset Firefox:

Also make sure that you allow Firefox with restrictions in your security software (firewall, anti-virus).
