I re-installed firefox as flatpak and it is still not connecting, when i try to connect i get this error on the keepassxc extension : Key exchange was not successful.
I installed both firefox and keepassxc as flatpak. What am i doing wrong ?
Connecting to native messaging host org.keepassxc.keepassxc_browser keepass.js:1003:13
Failed to connect: Unknown error keepass.js:979:13
Error: Could not establish connection. Receiving end does not exist.
so the issue was keepassxc was enabled for chrome but not firefox...
so I guess, change this to... maybe handle this error and give more helpful error message. Perhaps... "KeepassXC is not configured, please set it up in preferences > browser integration and make sure <browser> is checked" or something
I found a way finally, but not with flatpak or snaps. I installed firefox from Mozilla builds like shown on their website : Install Firefox on Linux | Firefox Help
