That heavily depends on how much of a hassle the container system is, really. If specific sites automatically get opened in a specific container (a la facebook) then I'm certainly going to take advantage of password saving. Anything to have to not type and/or click fewer things to actually do what I want to do, instead of getting to what I wanted to do.

If I have to manually open the correct container first, though, that's a hassle. It's why I use containers sparingly, but hot damn do I have the "facebook container" extension installed (a site I look at maybe once a week) because automatic silos are fantastic.
