We've had a bunch of great feedback in our Chrome extension forum from 1Password users willing to help us test our alpha Chrome extension—thanks folks!
For those just tuning in: yes, we have an alpha version of a 1Password extension for Google Chrome that you can help us test. This blog post has instructions for getting setup and where to post feedback. Just keep in mind: it's an alpha, so it is nowhere near feature-complete, and it can be rough around the edges (sometimes rougher than a beta!).
Since releasing out alpha Chrome extension for testing, we've had some questions about how to get the latest and greatest version. To help clear things up, here is an answer that I think will please everyone: Chrome automatically gives you the latest and greatest version! Chrome auto-updates its extensions, and we made sure that our alpha extension works with that system.
According to a Google Chrome support document, "extensions automatically update whenever an update is available." So you should be all set!
Thanks for helping us test our alpha extension for Google Chrome, and be sure to leave feedback in our Chrome extension forum and check out Chrome extension changelog for a list of fixes and new features!
