I came here to ask a question, hopefully one other people would like answered also: If the funding for the FireFox web browser combined with all Mozilla projects/products, or is there some separation? I would like to donate just to support development of the FireFox browser. Is that possible? FireFox containers is a very important feature to me and supporting FireFox and containers is something I would like to support at a higher level than the few random Mozilla donations I have made in the past.
