I had a look at Firefox and a huge amount of bloatware appears with it, World of Tanks, Rocket, Driver support, Norton, System support the list goes on. Some of them were blocked by Malwarebytes thankfully. Is there a version without all this rubbish please.

Get it from mozilla.org
http://www.mozilla.org/en-US/firefox/all/

Choose the version for your language and operating system.
I assume you'd want English (British)
and not English (US)

Or you can get the extended release version here
http://www.mozilla.org/en-US/firefox/organizations/all/

During install, keep an eye out and uncheck any boxes for "extras" that it offers you.

It sounds like you may have downloaded it from a site other than Mozilla - so far as I'm aware, there should be no additional software included.

Try this site: Mozilla Firefox

Thank you Inland AZ, will try again.

There is absolutely no bloatware with Firefox. I just put it on a new computer for someone last week. You downloaded from a website other that Mozilla Firefox as Inland and Jenny said.
