Firefox running in the background every time I start up my PC

Every time I start up my PC I can find a firefox.exe process in the task manager that uses 40-50% of CPU and I have to terminate the process manually every time. Firefox is not enabled in my startup so I don't know what causes that process to show up and use that much of my CPU (note: an opened firefox browser with multiple tabs only uses around 5% of CPU just for reference)
