Why would people insert their recovery phrases in to an add-on? The only add-on I trust is Meta mask, even with Meta mask I don't import my eth wallet that consist of huge funds, staying safe is very important if you don't want end up with nothing but bad news
Yeah I found out metamask is relatively safe, but I don't risk much funds to bring in there since it is in the damn browser where I can surf without vpn, so its not safe in general
