It does the job quite well.
Most of the time, I have to go through the credentials pop-up twice, when I load the page and since the password field is often not detected, once again by re-detecting. A minor inconvenience.
Since a recent update, it detects wrongly some fields as username fields. This problem is still present for me in version 1.1.5 yet less prevalent.
While I don't think it would be easy to do, detecting TOTP would be appreciated.

EDIT: I have to commend the team for their quick responses and action, especially with the "cpu bug" blunder.

This extension breaks XML rendering - see https://bugzilla.mozilla.org/show_bug.cgi?id=1401793 .

Good when it actually works as intended, since it has extremely inconsistent behavior. Losing connection to KeePassXC, pestering for inputting login credentials when there are no inputs in the page, prompting with a modal and then requiring (sometimes) to autofill manually from a dropdown in the input... Just had to disable it due to how annoying it is in its current state.

EDIT: Can confirm that 1.1.5 fixed the most annoying issue. Updating my rating to reflect the quick response to feedback and the problem being gone.

Por el momento perfecta para integrar KeePassXC en Plasma :)

Unable to add database, so it's useless.

Edit: I was able to connect my database. I'm using Firefox Portable, which doesn't work with the default proxy. Make sure the "Use a proxy application between KeePassXC and browser extension" is unchecked, and it should connect.

It works on most websites, but I've encountered a few exceptions here and there. "Choose own credential fields" doesn't seem to make any difference. It's cool though. Overall I'm very pleased with it. I never used a local password manager before, because I always used the build in password manager of Firefox. Using KeepassXC is much better, in my experience. I can store everything there, not just web related keys. Software serial keys, account passwords, everything. Since it is all stored locally, within my control, I feel at ease doing this. Anyway,

Works perfectly on linux.

Es wäre schön, wenn die Einstellungen dieser Erweiterung auf Deutsch übersetzt würden.

Update: Resolved! Thank you for the quick response to this bug.

Looking forward to the update -- the May 10 version is crushing Firefox when visiting the few Discourse-based forums sites I visit, including meta.discourse.org. 100% CPU on one core, Firefox UI frozen. If that helps.
In general, I *love* this plugin.

It works quite well, but since the last update (May 10) it makes firefox on Debian Stretch very slow, almost unusable.

Marked it 5 stars as I like it. It generally works. However, with the latest update, it seems to cause heavy CPU usage due to an unresponsive script when I have Twitter open and the Twitter tab selected. Have updated to latest KeepassXC (2.3.3), have forgotten all browsers and reconnected the database. Have removed and re-added KeePassXC-Browser - same. Removing the add-on stops the heavy CPU usage and the poor browser performance on Twitter.

Used to be perfect. Since the last update it fills in every single search field on every single page I visit. It seems the new username field detection errs heavily on the side of "fill in username in every field".

Every page I open it asks for permissions, every time I click somewhere my email adress is entered in a random input field. Browsing has become a nightmare.

Great work, the add-on works perfectly in Windows.
I will try to check if it works equally well on the GNU / Linux system.

Pretty good

after tweaking a bit works. however, some sites do not, especially those that have the 2-step style login, where you get the first window where you input the username and the second page for the pass, like paypal and google. also paypal from within ebay needs "manual" input. seems to have issues with drop-down or pop-up style password windows that do not have a dedicated permanent-showing login/pass filed on the original page.

I can not manage to get this add-on running on Windows or Linux.
The following KeePassXC databases are connected to KeePassXC Browser.
Identifier Key Last used Created Delete
No connected databases found. "
I know where the database is, but I can not find a way to connect.

"KeePassXC browser has encountered an error:
Timeout or not connected to KeePassXC "

The documentation at https://keepassxc.org/docs/keepassxc-browser-migration/ looks good, but the input windows for the connection do not appear on my PC.

Thanks to the developer for the link to the troubleshooting guide.
Unfortunately, the first step already gives up puzzles:
Where can I find the org.keepassxc.keepassxc_browser.json native messaging script file to store it in the specified directory?

A link to a help forum would be useful.

Unstable work
