Worked for a few days then started saying "Key exchange was not successful."
Had to reinstall the addon in order to reset it.
Beyond that it is good and probably the best option for integrating Keepass.

Please get the recommended tag.

Fonctionne très avec KeepassXC, la complétion automatique est performante même avec plusieurs identifiant, et la possibilité de choisir des champs d’identification personnalisé est la bienvenue.

The add-on works exceptionally on Windows 10 but for some reason it can't integrate KeePassXC database on ZorinOS 15.3, not even with AppImage version. But it's still an excellent program.

EDIT: see bottom for additional (positive) impressions and alternatives.

Original Review:

This is almost perfect, but KeePassXC-Browser is having problems with certain websites which require more than a UserID and Password field.

For example, on the American Airlines site, a username, *last name* and PW are required. While KeePassXC allows me to enter additional attributes like "Last Name: Doe" into advanced, there does not seem to be a way to invoke pasting it into the form.

Even If one uses the "choose custom login fields" there is no way to set the last name field as one of the options . . .

Ah, well. At least there is auto-type! :-)

EDIT: The developer is fantastically responsive, as seen below (and I was also e-mail directly with further comments, a nice touch!). I pointed out the built-in documentation (of KeePassXC) is missing the "KPH:" detail (required in KeePassXC-**Browser**) given in the response (but *is* shown in the online docs which I had not yet read).

Hopefully the built-in docs and online docs become better synchronized.

If you anyone still has problems with KeePassXC-Browser, it seems there are other Firefox add-ons which can connect to KeePassXC such as "KeePassHttp-Connector."

Also, standalone add-ons such as "Owl" (not yet reviewed, but much newer than...) or "KeePass Tusk" make the promise of not needing to install a connector to KeePassXC in the first place.

Very useful extension, fast and easy to use.

It would be wonderful if, when multiple logins are found for a web site, one could directly choose the wanted one from the authorization popup of KeePassXC (provided it's enabled), instead of authorizing then choosing.

The 1.7.0 version of addon dosnt interact with 2.6.1 version of application and 80.0.1 of firefox. Please update it.

Latest update popped up a demand for a new permission, "Access browser activity during navigation". Why is that suddenly needed when it was not needed before?

Addon très utiles et essentiel pour utiliser KeePassXC. la mise en ouvre est très facile. a recommander pour ceux qui souhaite + de sécurité sur leurs mots de passe (voir comment fonctionne KeePassXC)

I switched from Bitwarden and I'm missing nothing.
I use it on FirefoxPortable from PortableApps.com

I only wish that it supported the portable version of KeePassXC from PortableApps.com

edit:
I could connect it to the portable KeePassXC.

edit 2: Actually, I don't think the guide really did the trick. I only changed, in the .json, keepassxc-proxy.exe to keepassxc.exe. This change was reverted automatically by the program.
Rather, the solution was to install KeePassXC on Windows (non-portable). After uninstalling this, it again doesn't work.
