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.

A good add-on that works well. Unfortunately, it does not work with Firefox when Firefox is installed as a Snap package.

I've used this extension for sometime and like it. However, lately I'm prompted to update KeePassXC to 2.5. Using Linux Mint 19.2 this has to be a flatpak or snap repo. Non-bueno. Have to add a script for the snap repo version as it is sandboxed. Muy mal(not sandboxing, just the other stuff).
So my mild aggravation is that I'm unable to set the update preference to never and have it stick. On the positive side it adds a nifty little four-pint lime green star to the extension icon. Kinda like it actually
I know, a bit nit-picky but I is what I is. Thanks for the wonderful extension to go with the fabulous password manager. Peace, love and Linux.
