Installed this piece of crap calculator again by mistake and came with a nice HIDDEN bonus. Superfish browser hijacker. REALLY DUDE!
Last time you had SMART LINKS. Now you have SUPERFISH... You just love to sneak these hijackers in don't ya?
Marc Belmont shame on you for cheapening yourself.
Superfish made my browser not respond to mouse commands at times.
Plus kept popping up with these ugly suggest boxes on every item on the page.
As soon as I uninstalled it, the STUPID SUPERFISH went away. But from what I have read online, the fangs of this stupidfish stays on and I need to find and unistall it on my other browsers.
Marc Belmont, Thanks for ruining a perfectly nice evening.
If its a couple of dollars you needed, send me your PP address and I'll send you some cash.
What a shame.

New version comes with search hijacker. Dude just wanted a simple calculator, Don't need you to hijack or "SUGGEST" me search results. As dumb of a move as I've seen. Stay away from this unless you want to have all your search results redirected to other "RELEVANT" sites. JUST WANTED A CALCULATOR

SmartLinks is not a search hijacker. SmartLinks is an opt-in service that provides links to sources such as wikipedia. It is not required to run calculator and is only installed if you click the Accept button on the SmartLinks opt-in dialog. At any time if you change your mind you can remove it by going to the Firefox -> Tools -> SmartLinks menu and disabling or removing it.
