I've installed the latest Firefox and it now blocks by default all the analytics tags I manage (Adobe Analytics, Google Analytics). I understand this can be used by these companies to cross-track users, even though I cannot.

Whilst that's great for the user's privacy, I believe these aggressive practices by Mozilla will only hurt their bottom end. A few sites (Saas) I use already don't perform as well in Firefox as in Chrome and I fear that large companies like Google and Adobe will have now even less incentive in making their platforms compatible with Firefox.
