can you tell me how you installed logo in address bar.

im looking on my firefox browser and i see your logo icon in it. i want to be able to do that for my website. how is that possible? and how do i install it. if you can give me the installation instructions i would thank you.

i've always wondered how you can put your own logo or icon at the top of the browser in the adress bar. thats pretty cool trick. when i first saw that i thot to myself. how do you put a picture on the address bar? at first i thought it was something that your browser came with or i thought that you have to submit your information on some website or something. but that can't be true. can you show me how you did it
