Troubleshoot Firefox issues caused by malware

Sounds like your were "offered" a fake update; I hope you stopped that installation after reading the EULA.

See this - http://malwaretips.com/blogs/binkiland-search-removal/

You also appear to be running an outdated Firefox 32 version.

Please update to the current Firefox 35 release.

You can find the full version of the current Firefox 35.0.1 release in all languages and for all operating systems here:
