Vivaldi Browser

Vivaldi still support Mv2 as long as possible, but anyway Mv2 will die for all browsers sooner or later, like Mv1 in 2013. Mv3 has a different cookie handling with better privacy, but in adblockers is somewhat more limited in blocking filters. For practical purposes the difference is minimal, AdGuard and Adblock Plus are already Mv3, uBO, due to the intern algorrithm isn't yet compatible with Mv3 and only released an uBO Lite which fullfit Mv3 with the uBO basic functions to block ads and trackers, The inbuild Vivaldi blocker is not affected by the change, it does a perfect work, but is discovered by the anti adblock algorrithm of YT, there the workarround is using the Vivaldi trackingblocker + uBO Lite, which is capable to spoof the adblocker, until the Vivaldi devs solved this issue. Not so easy, because YT change the algorrith pretty often.
