First, love this one: https://addons.mozilla.org/en-US/firefox/addon/plain-text-links/ https://addons.mozilla.org/en-US/firefox/addon/plain-text-li... Second, here are some ideas that may or may not feel scummy: 1. Advertise in non-intrusive spaces. Upon update, some add-ons automatically open a window with the changelog. Using this space and the space on the add-on's Mozilla page, to advertise. 2. Get a sponsorship. On a related note, pitch to companies that target similar audiences. Offer the first few placements for free (or set low enough price that there isn't much risk) and track the traffic. Use these numbers to set a price. 3. TwitterBar "via" field. Twitter links to the webpage for apps that people use to post messages (at least they used to). This should give you leverage to rank any other webpage highly from all the pagerank juice. 4. Opt-in link juice/affiliate links. A number of the add-ons could potentially have affiliate ID's appended or a link included back to your product page (similar to Twitters "via" links). Once, you have high ranking pages, the monetization options are unlimited. 5. [Lastly] Gather email addresses. Perhaps there is a reason users would want to provide their email address? As you mentioned, combining add-ons with a hosted service opens up a lot of opportunities. Email addresses can be used to provide value in a number of different ways (e.g. get beta testers, etc.). Good luck!! P.S. One more, use your skills to get hired by companies who could benefit from developing Firefox add-ons for their products.
