Removed most of the extensions from Vivaldi. Is there any reason why HTTPS Everywhere and Bitdefender Trafficlight should be removed?
You can use either bitdefender trafficlight alone or netcraft + WDBP together
Trafficlight = phishing, malware, scam filter
Netcraft = advanced phishing
WDBP = probably agressive against pup/pua stuff
You have chrome safe browsing also in vivaldi
Its up to you wich you use though
About https everywhere, most sites use https anyways so its kinda redundant, just enable ://flags instead to enforce connection to 1.1 1.0 tls and change treatment for http pages to non secure, its all fine unless you login to unsecure sites
Aswell the https everywhere force all pages to https will still leak mixed images , when with firefox you can enable https only mode that is more advanced than the extension itself
But if you like the extension go with it, i just see it useless unless youre using tor
