Not really, because there aren't any thoroughly supported, mainstream browsers as clean of spyware features as Firefox.
I'm not saying I'm leaving Firefox, but I am going to reevaluate which browser I choose. Mozilla lost a lot of trust from me and I am going to reevaluate how I interact with their products.
If supported, mainstream, and clean of spyware are the three boxes you are trying to check and you still feel Firefox checks them, great. But, now is as good of a time as any to reevaluate why you are using a browser and if the browser really meets what you are looking for.
