Firefox Blocks 0.0.0.0 IP Addresses: Tell Us What This Means To You!
(connect.mozilla.org)
A place to discuss the news and latest developments on the open-source browser Firefox
I just wish they'd stop blocking http requests on lan addresses honestly.
Thanks for the suggestions. While I was investigating I ended up looking and had a proxy issue. Obviously a problem on my part.
Do you have standard Firefox with default options that does this? This has not been my experience.
You could try out with a new profile if it works out the same.
I just tried to use the Developer version. With no addons.
