Seems like you have two problems:
1. Browser extension icon is not pinned to your browser
In Chrome, do you at least see see the “Extensions” icon ( shaped like a puzzle piece ) to the right of the browser’s address bar? If so, what do you see when you click on the puzzle piece? If not, what happens if you access the following URL (in Chrome)?
Make sure that the Bitwarden extension is active (“On”). Do you browse in Incognito mode? If so, make sure that you enable the option “Allow in Incognito”. After you have done this, if the Bitwarden shield icon has not appeared next to the puzzle piece icon, then check again what happens when you click the puzzle piece icon. You should see the Bitwarden extension listed, and you should be able to click on the pushpin icon () to “pin” the icon to your browser address bar; if you are in Incognito mode, you will need to temporarily exit Incognito mode (i.e., open a regular browser window using Ctrl+n) to complete the pinning procedure.
2. Cannot find the browser extension settings
First, you need to open the browser extension. If you were able to pin the browser extension shield icon, click on the icon. Otherwise, if you can at least see the puzzle piece icon, click that icon and then click on Bitwarden in the list. If this doesn’t work, try using the keyboard shortcut Ctrl+Shift+Y (while in Chrome). In Chrome, as a last resort, try using your browser address bar to navigate to:
Second, unlock your vault if it is not already unlocked. If you don’t know how to do this, please ask.
Third, look in the lower right corner of the Bitwarden browser extension window, where you should find a gear icon () labeled “Settings”. Click the gear icon. This should take you to the Settings page for the browser extension. Here, you will find the options I was describing in my previous post.
