i mostly use a vivaldi or opera portable for those. unzip, run, use the temperamental site, close, delete directory. it’s not very often that i have to do this.
but for a couple of pesky sites i do frequent a bit more often, i keep their portable browsers to reuse and have them configured (including addons) specifically for them.
if google cared, they’d vet ads and ad links, and guarantee their safety and security.
if google cared, they’d put a stop to seo ‘optimizers’ and scammers scoring top positions on serps.
but google doesn’t care about anything other than their profits and share price.
adblockers can affect both of those. they’re using the weak cover of ‘security’ enhancement to neuter them.
existing adblockers provide more safety and security than what can be realized by the shift to mv3.
