if youre fine with it, you can just buy a portable bluetooth speaker and not use the bluetooth. many of them work with aux and dont turn on bluetooth until you press the pairing button

for me ironfox runs way slower than firefox and i dont know why. im using the same exact extensions on both. id prefer using ironfox but its borderline unusable (im on a pixel 9a running graphene)

thats why i only buy devices with an unlocked bootloader
