Pretty iffy so far. The add-on seemingly decides on a whim, whether or not to save new passwords. Occasionally I'll have to manually update generated passwords in the vault. Doesn't seem to recognize the difference between, "old password" & "new password" spaces in forms. The sidebar for logging in oftentimes doesn't appear. Lastly the UI is just painful to look at, but other than those problems, it's functional.
Thanks for the feedback! If you are having issues with the sidebar, try refreshing Firefox https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings as that doesn't sound like expected behavior.
Are you keeping your vault in a locked or logged out state? https://bitwarden.com/help/vault-timeout/
