This extension is the main reason why I had problems switching to Firefox, since there was no equivalent.
Now that it has been ported I can finally use the new Firefox 57+ just as comfortable as I used Chrome before.

Big thanks to the developer!

OK, my approach was way to complicated, when it's indeed so easy!
I thought, giving each Firefox-profile a separate KPH-Connector key, each profile would now also only see it's own bunch of passwords in the single shared KeePass-DB… but of course, that's not how KeePass works, so following your advice all is now working as required – THANKS ANDY, GREAT WORK!

How should I use it with multiple profiles, that all should share the same passwords via KeePassHttp-Connector, but have otherwise different browser settings?
Each time I click on Connect, it creates a new connection-key in KeePass, for each profile – the existing connection-key from other profiles in KeePass are not recognized and giving the new key the same name as the existing one, a dialogue opens "Overwrite existing key?" with question "A shared encryption-key with the name "KeePassHttpConnection" already exists. Do you want to overwrite it?".
Doing so now deletes the previously set connection in my other profile.
What to do?

Works flawlessly. Good to see Keepass support continuing in Firefox!

KeePass 2.42 dont support KeepassHTTP plugin...

Simple and Solid - Flexible and Fast

It's a perfect port of the chromeIpass extension. Keep doing the good job, I need this on a daily basis!

I love chromeIPass and this fork seems to be the closest thing to the Chrome extension, that is working with FF57 out of the box.

Missing the context menu fill options tho.

works okay. barebones.

Already worked well in Chrome before, and maintains utility now in FF

Been using KeePassX for sometime then informed of fresher repo in KeePassXC only recently. Spotted the old connector and had a sad it didn't work in Firefox Quantum. But now I has a happy!

Setup was pretty simple. Database had to be unlocked for the WebExtension to find it as a source but even my uncaffeinated brain managed it. Works a treat. Would prefer it locked via my Yubikey too and with Firefox rocking through U2F implementation https://wiki.mozilla.org/Security/CryptoEngineering your extension is a cornerstone of my workflow. Nice work!!!

Early days, but very pleased to find it works well with Firefox 55.0.2 (64-bit) on my Ubuntu install (17.10 beta). This now means I can move across to KeepassXC instead of Keepass2 with Mono. The only issue I had was making sure that the KeepassHTTPServer was running in KeepassXC (remember to restart); without doing this you can't connect! It is also nice to be able to manually approve access to a password rather than just blindly fill (if you want to).

A must-have! Works perfectly with Firefox Dev Edition (based on FF57) / KeepassXC and ArchLinux.

Excellent add-on, happy to see this on AMO!
