Firefox will support the ad blocking extension 'uBlock Origin' that will no longer be available on Chrome so that users can continue to use it



The popular ad blocking extension '

uBlock Origin ' relies on the functions of the extension specification 'Manifest V2', so it will become unusable when Google Chrome switches to Manifest V3. However, Mozilla has announced that it will continue to support the function so that 'uBlock Origin' and other extensions can continue to be used in the web browser 'Firefox'.

Chrome and Firefox each have their own implementation of the extensions spec, but they are designed to be as compatible as possible, but there are still differences in their approaches, which results in differences in the extensions available.

One of them is related to extensions that block ads and trackers. Google plans to crack down on extensions that block ads and trackers from 2023, and is gradually phased out the extension specification 'Manifest V2' and switching to 'Manifest V3'.

With Manifest V3, the content filtering APIs 'blockingWebRequest' and 'declarativeNetRequest' that have been used by extensions that block ads and trackers will no longer be available. The Electronic Frontier Foundation has expressed concern that this will make it 'more difficult to block ads and trackers.'

Meanwhile, Mozilla, the developer of the web browser Firefox, stated in 2019, when Google was formulating Manifest V3, that it had no plans to make changes that would restrict ad blocking.

Mozilla has now reiterated its intention that Firefox will continue to support 'blockingWebRequest' and 'declarativeNetRequest', while Google will completely phase out Manifest V2 in mid-2025.

Mozilla says it continues to support the browser in order to provide flexibility to developers and powerful privacy tools to users.
