I've recently downloaded PaintTool Sai and read through all of the important things that needed to be read. After installing it, I went to firefox and opened the browser. After realizing it wasn't the right browser, I reset it and opened a new tab with the little + sign beside the orange FF tab. After I clicked it, it sent me to: Sweetpacks Search and I tried to reset my browser again but it won't go away. I tried to disable my add-ons but I don't know how and I'm too afraid to mess up my new laptop. Please help, I'm desperate. Thanks.
