Firefox Support Forum

When I paste an URL with a port number in the address field of a new tab and press return, then the port number gets removed.

Example: I paste "http://localhost:5707/typo3" and press return Firefox then tries to connect to "https://localhost/typo3/", which is SSL and has no port number.

How can I disable that behavior?

This happens with Firefox 84

Hello,

When my Openconnect VPN is on, Firefox takes very long time to open links from outside its own window: ie links opened with xdg-open in Linux (Ctrl+Click). If Openconnect is Off, links open almost instantly as expected.

Here's /etc/resolv.conf when Openconnect is Off. And here /etc/resolv.conf when Openconnect is On: search contains 11 internal domains. Environment: - KDE Plasma 5.20.5 - Firefox 84.0.2 - xdg-utils 1.1.3 - networkmanager-1.26.4 - networkmanager-openconnect-1.2.6 - openconnect-8.09

System proxy settings: No Proxy

What I have tried: - Start Firefox in Safe-mode (no effect) - Explicitly setting Proxy to None / System Default in FF settings (no effect) - Opening links resolvable only inside VPN and just google.com (no effect) Only turning Off Openconnect helps so far. I suspect it's got to do with name resolution (maybe routing as well?), but have no conclusive evidence. Btw, Chrome is not affected by this behavior.

Thank you
