1Password has integration with Firefox, Safari, Chrome, and presumably also IE.

They don't build their own browser into which their tool is built, no.

They don't provide you a browser-only solution like LastPass, no.

But they do fully integrate with most of the common browsers.

Doesn't help in this situation-- you need to be able to install the base executable for the browser extensions to function.
