They can start by stopping to bleed the Firefox team dry (they use the income they get from Firefox to fund everything else, none of which is important).

If they promise to focus on Firefox again, and with that money they can probably hire a bunch of world class programmers. At least I think the combo of a real mission and decent pay should go a long way.

And, if they somehow get rid of their current management and apologize profoundly I and others will probably start donating again. It will also result in more users and more business in every way.

Today it seems they are paid to make the web a Chrome monoculture only with plausible deniability.
