In theory it's a nice idea, but it's hard enough to persuade my friends and acquaintances to try Firefox (again, since many of them left between versions 4 through 56). If they visited the website and were asked to make a donation, they'd think Firefox has become commercial software and will leave immediately. This will hurt their market share even more, if anything. Ubuntu tried that one, and it wasn't very effective.
