For anyone curious as to how I solve the problem right now, I just have two separate Firefox profiles. One has a ton of plugins; I use it to browse the web. The other has no plugins; I use it to visit my bank's website.

That's a good question. I don't know -- I never considered private browsing. If I close a private browsing session, are all traces (ie: cookies, history, etc.) of it erased? If so, I don't think that's what I want. I'm okay with my bank (and websites I trust) setting cookies, for example.

I do the same, but because I think it’s important to see what the average use will when using the web. Especially if you’re working professionally with the web in anyway.

Sure, but my bank and (like most other highly trusted sites) doesn’t set any useful cookies anyway. I think there is an option to autofill my username, but why bother if my password manager does that anyway?

Browser plugins generally have privileged access to data exchanges between user and remote server. So, they could potentially spy on you and scrape your secrets.
