Media keys captured by Firefox

Hi, For a couple weeks now, whenever Firefox is open, I can't control other software with the keyboard media keys. I had fixed the problem before by setting the flag media.hardwaremediakeys.enabled to false, which worked for a while. But now it doesn't. I also tried setting dom.media.mediasession.enabled to false, and all 4 combinatios of the 2 flags. Firefox keeps capturing media keys. Tried disabling every addon shortcut too, as some other webpage recommended.

Note that it happens even if there's nothing in firefox, ie 1 tab on the "home" screen. Close Firefox and Spotify starts responding. Open Firefox and it stops working.

Using Firefox v87.0

Well I'm not sure what changed but right now it's working again.

(I had opened/closed Firefox multiple times with the issue being recreated (firefox open = media keys dont control spotify); then the keys stopped working even with firefox closed; relaunched spotify and now they work fine even with firefox open)
