Works well in FF and it is good alternative for internal FF keystore crash (covered by automatic backup for keepass database).

it works on linux, no special character rendering issue nor dpi scaling issue like keepass mono

EDIT: This issue has been fixed. Props to an active development team.

An issue has been submitted on Github. Props to an active team who bothers to read bug reports.

After updating KeePassXC to 2.3.4, the extension works only if programs are opened in this specific order:
-Make sure everything is closed (browser and anything KeePassXC related)
-Open Firefox
-Then open KeePassXC

When the extension works it works wonderfully, but field detection does fail on some login pages such as the Google account one where you type in a username, then click next to type in the password.

fait parfaitement sont travail , très sécurisant et ne bug pas.et aujourd'hui toujours valable aucun problème a ce jour

Works perfectly, great to have it working consistently in both Windows and Linux and Chrome and Firefox. Really convenient.

Por el momento perfecta para integrar KeePassXC en Plasma :)

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.

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.

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