(UPDATE: SOLUTION FOUND. See subsequent post.)
In Firefox 84.0.2 for Windows, the Kee extension stopped working for me this week, after having worked well for years, including on the same websites where it has previously worked.
Websites with KeePass entries no longer autofill, and the little “V” Kee icon no longer appears in any form fields. KeePass itself continues to work, and the KeePass hotkey works as it previously did, for some websites. The Kee extension icon still appears in the browser’s toolbar (without “OFF”), and the padlock icon in the Kee drop-down menu is still green.
None of my Kee or KeePass settings have changed. I am running Kee 3.6.27, Keepass 2.47 (although this issue also existed in 2.46, before I tried updating this morning), KeePassRPC 1.14, and Firefox 84.0.2.
Reinstalling the Kee extension did not fix the issue, nor did revoking authorization in KeeRPC and re-authorizing.
Oddly, when I autotype a stored password from KeePass, Kee pops up its “Do you want Kee to save this password?” message, even though the password is already stored in (and indeed is being autotyped by) KeePass. It’s as if Kee has become totally disconnected from KeePass, despite the toolbar icon being the normal color and the padlock icon being green.
Chrome is also affected. Odd.
