FireFox extension donation
cfinke: When the contributions program started, I enabled contributions for a number of my add-ons, with the suggested donation set at $1.  Over the next two months, I averaged $1 in donations for every 5,000 downloads.After Add-on Con, I raised my suggested donation amount to $5, and since then, I've averaged about $4 for every 5,000 downloads.Note: Relevant add-ons include TwitterBar, Feed Sidebar, and FireFound, which was a grand prize winner of Extend Firefox 3.5.
