Hello Raj,

there is a cool add-on that can block all kinds of advertisements: It's Adblock Plus. Please read the AMO description page for this add-on under https://addons.mozilla.org/en-US/fire.../1865.

Kind regards, Tobbi Firefox Support Volunteer

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

Do a malware check with a few malware scan programs.
You need to use all programs because each detects different malware.
