As a recap, Manifest V3 restricts the blocking capabilities of Web extensions, [making it harder](https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-asked-questions-(FAQ)#filtering-capabilities-which-cant-be-ported-to-mv3) for privacy-enhancing extensions such as uBlock Origin to protect users. The privacy community has already begun releasing experimental versions of ad block extensions that are rebuilt from the ground up to meet the new constraints of MV3: [AdGuard AdBlocker MV3 Experimental](https://chromewebstore.google.com/detail/adguard-adblocker-mv3-exp/apjcbfpjihpedihablmalmbbhjpklbdf) and [uBlock Origin Lite](https://chromewebstore.google.com/detail/ublock-origin-lite/ddkjiahejlhfcafbddmgiahcphecmpfh) are just two examples. And we've seen that these experimental versions _do_ block ads and other unwanted Web content. However, MV3 imposes new limitations, such as a cap on blocking rules, the removal of background scripts, and changes around cosmetic filtering. Overall, these new MV3 extensions lean on workarounds to solve problems MV3 itself introduces.
