cool customization ^o^

so i was playing around with firefox addons, when i found out they didnt work, i was rlly dissapointed :/ (im on windows XP btw, so newer versions of firefox didnt work) but i DID find a new method, and now my firefox tabs r galazy colored :O, ok so first ya need to go to the three little lines, go to customize, it should be at the very bottom, and then after that, you need to go to the VEERYY very bottom to find themes, its pretty cool :D
