Hello, I'm not too sure what MyWay is. But you can see if it's added to Firefox or not via pasting this (about:addons) into your FF browser. Check Plugins + Extensions.

If it's not in here you can refer to checking your PC. Windows key --> Settings --> System --> Apps & Features. or control panel --> uninstall a program --> right click desired

From recent discussion and research, it is in fact an infection. Please refer to the below: That myway.com is a browser hijacker, that you'll of course need to get rid of:

Go to the 3-bar menu --> Addons --> and look for any unfamiliar or suspicious looking extensions, like e.g.:

SafeSearch Incognito SearchAssist Incognito

When you find any: remove them.

Also look in: Advanced --> Network tab --> Under : 'Offline Web Content and User Data'

Do the same in Windows' Control Panel => Programs.

However: most malware will be 'hiding' somewhere , so I'd recommend running malware scans :

Run most or all of the listed malware scanners. They all work differently - what one program doesn't pick up, the other might.
