how do I get rid of "TrackaPackage"?

Hello. First and foremost check Firefox for any unwanted Addons/Extensions. Paste "about:addons" into your URL Browser bar and search for that pesky Browser Hijacker. After this, check your computer, you can go to control panel --> Programs and Features --> uninstall anything fishy or relative to that TrackaPackage annoyance! Once you get this far, I'd 100% suggest a Malware and AdWare scan. You can do so via Malwarebytes. https://www.malwarebytes.com/products/ Both are free, well.... Malware protection is on trial, but after the trial you can still scan and find threats.
