We install the LINE Chrome Web Store desktop extension .
We browse its URL,
chrome-extension://ophjlpahpchlmihnnnihgmmeilfjmjjc/index.html#popout
OK, Bitwarden recognizes it. But cannot go to any fields to fill in our credentials.
(We note that if we hadn’t browsed its URL, and instead just clicked the LINE icon in the extension bar, the new tab created would have no Bitwarden icon to click. Also in any case there is no right click menu to use when trying to fill in these fields.)
