@ivantha Glad you found the setting for customizing URI match detection!
For your case, you could use either “Starts” with or “Exact” as your matching method, depending on whether or not the login form URLs have any variable characters at the end of the URL string (e.g., tracking info, redirect info, etc.).
To use the “Exact” matching method, it is best to capture the URI by navigating to the login page, opening the details view for the corresponding vault item, and clicking the Auto-fill and save button below the item details. Then edit the vault item, delete any old URI strings (other than the one just added), and set the URI match detection to “Exact”.
With regards to your inability to vote, that is an issue that has been plaguing the forum recently, but was supposed to have been fixed last week. Try logging out and back in and/or clearing your browser cache, and if you still are unable to vote, send a DM to @sj-bitwarden.
