To be fair, what I have heard (I am not a Mozilla insider so I can&#x27;t say personally) is that donations go to the Mozilla Foundation and the commercial agreements give money to Mozilla Corporation. So you aren&#x27;t donating to the same place.<p>From the same source, apparently the Mozilla Foundation does a lot of important work that the Mozilla Corporation can&#x27;t&#x2F;won&#x27;t do but most of the development is done by the Mozilla Corporation currently (possibly due to not enough donations to the Foundation?).<p>I haven&#x27;t really verified that, but thought it was worth pointing out.
