I love this browser ( with a hint of chrome)You can play films get apps bla bla. I am a little tired of firefox ( firefox 22 with Aeon addon give a great look) The more recent firefox browsers are boring. I never use microsoft. I like Opera on my tablets because I think it's faster on the ipad air and Tab s. Anyway give Torch a go you can always get rid if it's not you cup of T.   

Any software you want to get rid of on your computer will leave bits and bobs after uninstall clogging up your hard drive. Uninstall and clear all the rubbish with Revo uninstaller it uses the software's normal uninstall process and then when the developer tells you it's all gone revo runs and you will be surprised how much is left.

As they say no such thing as a free lunch. A lot of freeware has addons bundled with the item you wish to download. ALWAYS go for a custom install when running the install programme you will then see things like ask and yahoo lurking there in the custom install. You then just  untick the boxes until you come to the file you wanted in the first place. I find Major Geeks a good site. http://www.majorgeeks.com/ ;  Softpedia has a lot of add ons as described in the freeware.
