I've never got one of those anti-adblocker messages on YouTube and I just use a vanilla browser with no addons and I get zero ads. The Channel 4 website won't let me watch anything without disabling the adblocker, so it's not like my browser is in some super stealth mode where servers can't tell I'm blocking ads. I'm not complaining though.
If you use a mozilla account it automatically installs addons that you have on other browsers, that might be why you think it's installed by default.π
Then I guess I must be getting special treatment from Mozilla then or somehow am downloading a different installer from GetFirefox.com because it's always been installed for me on a fresh install after a reformat or when putting it on someone else's computer since I switched back from Chrome after rumors about Manifest V3 started circulating a few years back. π
You are someone I most often agree with on Lemmy, but you are simply mistaken here. Plug-ins get restored if you login to a Firefox account, so perhaps thatβs why you think that itβs default for UBO to be installed, but it simply isnβt.
Im guessing adding plugins is part of your default workflow when installing browsers somehow. Ublock origin is the most used plugin on firefox Id reckon, but a fresh install doesnt carry it.
