By accident I made Mozilla Firefox as my run application for steam

[?Sir Info? 2]

I was trying to play fistful of frags on steam so I clicked the button and a notification popped up for a run application and I clicked Mozilla by accident and every time I try to play it it spams 2 tabs per second.
Anyone tell me how to fix this?

uninstall mozilla or run steam by going to the directory and clicking on the exe

uninstall/reinstall ffof, or try validating the integrity of game cache
