@sgunhouse Oh man, thank you so much. For some reason, an ad blocker extension I had imported from Google Chrome was preventing the mod from working. Again, my eternal thanks.

I've been using Opera GX for a while now, and I've never had this problem. Until recently, I was testing Opera, but then I decided to go back to Opera GX, because I like it better.

When I installed a mod for FNaF SB (Five Nights at Freddy's Security Breach), I realized that the mod's sounds didn't work. The background music, the keyboard sound, the browser sound, none of them worked. Even after uninstalling and reinstalling, it didn't work. I've lost count of how many times I checked the browser and mod settings. It didn't work in the normal tab. Strangely, when I opened a private tab, an incognito tab, the mod's sounds magically started working perfectly, even in the normal tab. I've tested several different mods, tried things to solve the problem, and so far, whenever I close the private tab, the sounds stop working.

Please help me, I want to solve this problem as soon as possible.

How can I solve this problem?
