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.

flawless

Works fine! Finally an "official" browser plugin! KeepassXC = best password manager.

Very cool add-on, works as expected!

I am finally able to shift from Kee and KeePass2 - much better UX!

A few places for improvement:
- I would like the UI font size a bit bigger - maybe some settings?
- It is a bit unclear what am I naming when connecting to a database - the browser add-on, or the database.

Other than that - so far so good - looking forward to keeping the 5/5 rating after a few weeks of usage :)

Finally we can get rid of that hacky KeePassHTTP stuff

The best password manager.

First was seeing "Timeout or not connected to KeePassXC" as well, but manually enabling "Proxy" and "Native-Messaging updates" in advanced settings for "Browser Integration" allowed me to connect Keepassxc browser to keepassxc desktop on macOS 10.13.3.
