The main reason of Google's financing is probably because they don't want to be accused of a browser monopoly. So this will stop, leaving Firefox with very little income.
I'm not sure if the reason you said is enough for them to keep paying.
Google search is not the same thing as google Chrome
The opposite. Google won't be able to leverage chrome to drive website design and Internet policy anymore and it'll give smaller companies an opportunity to get a better foothold in the market. That's the whole point in breaking them off from Google in the first place.
Currently, Google pays Firefox's bill by having them set their default search engine to Google.
This will no longer be when Chrome is in the hands of another party. DOJ is currently advocating for this forced sellout.
Why does Alphabet not controlling Chrome mean Alphabet would suddenly stop paying Mozilla to make Google Search the default search in Firefox? That's totally unrelated.
(Saying Alphabet instead of Google to help differentiate between Google and its products.)
Quite the opposite. The death of Mozilla Corp will drive the community to greater heights. I expect to see Floorp, Librefox, and even Basilisk/Pale Moon having a voice in the conversation of post-MozCo Firefox.
I switched to it some time ago. Took a while to find all the dials to turn to get some (trusted) sites to work, but the fact that it’s free of telemetry and has Ublock makes it worth it.
Chrome funding would shift, not necessarily stop. And having a dirty source of funds as your primary source is fundamental corruption. Even if works now, the future is bleak.
Even if Google stopped paying Mozilla, the organization has enough in savings to operate for several years. That’s plenty of time to cut back on spending and find other revenue sources. My only concern would be that they cut back on Firefox development rather than what I would consider a side project.
But the cost here is that, whatever Mozilla cuts, is going to hurt Firefox at some capacity. Mozilla recently had made cuts to where, they don't have a voice to advocate for open internet, for example. Which waters down what stand that they have to be an influence.
But also Internet standards are only getting more complicated... Eventually there will be no browsers left, and we'll have shifted to an app-only paradigm. Isn't that exciting.
Is there even a "before"? The very first release of Firefox was in 2004. Google started paying Mozilla in 2004. The only time there was no funding from Google was 2014-2017. In that time Yahoo took over that part.
There was however the 2 year period from 2002 - 2004 when Firefox was still "Phoenix" which was mostly funded by AOL.
To my knowledge, there is not a single moment in the life of Firefox when it has had to get by completely without external funding. And 95% of that time, it was Google.
