Out of curiosity, what orgs are you comparing us to?

When you install Firefox Preview, tracking protection is enabled by default. This is recently true for Firefox Desktop as well.

This post below by our CEO explains how we're thinking about the issue broadly. Your privacy and agency are definitely front and center.

Agreed. I hastily installed FF Preview and then immediately uninstalled it when I couldn't find where to install uBlock. They shouldn't have launched, or made an announcement, without some form of adblocking (native or plugin).

I understand that it's a testing release, but they stand to lose out on many testers and users. While I am perfectly willing to be a guinea pig and use this as my daily driver, I am passionately unwilling to browse with ads (especially on a mobile device where data is more expensive).

I am likely part of the vast majority of potential testers/users. There probably won't be a "hey, we support plugins/blocking now" announcement and, even if there will be, it probably won't be as visible as this announcement.

Did you actually try it on a website with lots of ads? I've been using focus for the last 6 months or so and the tracker blocking also blocks many ads for me. Also there is blockada which blocks ads system wide.

It doesn't block ads. It blocks trackers that sometimes happen to be ads too. But when it comes to ad blocking, it's no better than Chrome.
