@Melpren Thanks for getting back to me. I haven't seen any mentions of this around the community. Let's try out these steps for your Firefox browser while I have a trace enabled on your Pandora account.
If you still have trouble, let's try rebooting your connection:
Shut down your device completely;
Unplug your modem and router, wait one full minute, and then plug them back in;
Wait five more minutes to allow the modem and router to fully boot back up;
Turn your device back on and try Pandora again.
If Pandora still isn't working, could you check if you're able to connect to your network using another streaming service, such as YouTube?
Let me know how it goes.
