Firefox Blocking Custom Flags or Redirects from Game Launchers?

I’ve been testing how different browsers handle redirects and external triggers from game-related tools, and I’ve noticed something odd with firefox. When trying to launch certain experiences or apply custom settings from external links, firefox doesn’t always behave the same way as chrome or edge—it sometimes blocks or ignores the flag triggers completely. for example, I’ve been working with a roblox-related launcher that uses something like a [https://blxstrap.com/bloxstrap-fast-flags/ fast flag through bootsrap] to customize the client experience. everything works smoothly in edge, but firefox seems to either strip the flags or block the redirect entirely. is there a setting I should look into that might be interfering with these calls? could enhanced tracking protection or strict HTTPS enforcement be playing a role? would appreciate some help....
