Since Firefox is apparently going to follow google with blocking ad blocks, do you have any thoughts of what browser you might move to next?

Firefox said it will adopt Manifest V3 in the interest of cross-browser compatibility.

They adopt manifest v3 in addition to their current APIs. I.e adblockers on Firefox are going nowhere.

Firefox's implementation of Manifest V3 will work with software like ad blockers as it does not have the same limitations imposed on the browser side.

Having v3 is good, but only having v3 is bad. Is Firefox removing v2 support?

Manifest v3 doesn't prevent adblockers from working

Google has announced it will shut down Manifest V2 in June 2024 and move on to Manifest V3, the latest version of its Chrome extension specification that has faced criticism for putting limits on ad blockers.

Manifest V2 is the old model. The Chrome Web Store no longer accepts Manifest V2 extensions, but browsers can still use them. For now. Manifest V3 is supported generally in Chrome 88 or later and will be the standard after the transition planned to take place in June 2024.

MV2 is not required to block ads

It removes the dynamic mechanism. Under v3 adblockers wont be able to decide on the spot, only declare static lists.

chrome.declarativeNetRequest.updateDynamicRules allows for dynamic rules. It is not limited to static lists.
