For me personally, I don't actually trust any of that.

Any purchase I do online is done with a virtual card that links to a bank account that only ever has the amount I need to pay for whatever it is I am currently purchasing. That way it doesn't matter if the information is stolen etc. because there is no more money to use and I can cancel the card as easily as I can create a new.

For banking I also only use my banks official app, I don't know how exactly it works and I assume it does use some form of http and whatnot, but I wouldn't trust using a bank through the browser as you never know what kind of thing an extension or something have in there.
