I am currently running the MOSS (Mozilla Open Source Support) program, which is Mozilla’s program for assisting other projects in the open source ecosystem. We announced the first 7 awardees in December, giving away a total of US$533,000.
The application assessment process has been on hiatus while we focussed on getting the original 7 awardees paid, and while the committee were on holiday for Christmas and New Year. However, it has now restarted. So if you know of a software project that could do with some money and that Mozilla uses or relies on (note: that list is not exhaustive), now is the time to encourage them to apply. :-)
