Problems With Firefox Connecting To Local Sites On My Network

[mikey8811]

Hi

Since I updated to Sequoia I have had problems with Firefox connecting to local sites on my network.

I cannot reach my router admin page at 192.168.0.1 or other such addresses. Initially it happened intermittently. It didn't work at the start but would work after some time.

Now, it just doesn't work.

No issues with Safari.

Anybody else have this problem and how did you fix this?

Thanks

I am able to access my Synology router at the above local address from Firefox.

Are you getting any kind of error message?

As per screen capture

If I just enter 192.168.1.1 in FF it redirects to the URL I posted earlier. I wonder if you have some FF security setting configured differently than I do.

I don't know. I didn't touch the settings and it worked fine before Sequoia.

Same Here. I upgraded to Sequoia last night, and now Firefox is now unable to connect to any websites on my local network. I can only access sites on the internet. Safari Browser is able to access local sites OK, and all other local network services are fine. Only Firefox seems to be affected.

I updated a day after Sequoia came out so it hasn't been working for a while for me. I hope someone fixes it either on the Apple side or the Mozilla one.

Hmmm... I am also able to access my Denon receiver at this local address with FF. I did get the try again message, then it connected right away when I clicked try again.

Turn off Private Wi-Fi Address. If not work, also turn off Firewall.

Firefox 131.0.2 was pushed out today. Might not hurt to update to see if the problem goes away.

I am already on 131.0.2 - same thing

My Firefox is already updated to 131.0.2, Wifi disabled, Static Ethernet configuration, Firewall disabled. I have at least a couple dozen systems on my local network that can no longer be accessed via Firefox.

After the OS upgrade completed I was prompted to "allow Firefox to find devices on local networks?" "this will allow the app to discover, connect to, and collect data from devices on your local networks"

I clicked don't allow, as it sounded un-neccesary to "collect data" on my devices. I am unable to find any security settings in Firefox or OS X to adjust this option to see if this is why the web devices are no longer accessible.

Ah, I found it,

OS X System settings, Privacy and Security, Local Network, flip the slider on for Firefox. I am back in business!

I have the same problem, but I don't see firefox in Privacy & Security / Local Network. Is there a way to add it?

I have the slider already turned on from the start. No effect. I still have the problem

Thank you! That fixed it for me.

I've since found that MS Edge has the same issue, but it does have an entry in the Local Network app list, and it's slider is "on". Safari works fine, although like Firefox, it doesn't have an entry in the Local Network app list. I'm a little confused by this...

As I was typing this, I noticed @Grumpus reply above. I turned off "Private Wi-Fi Address" and access to 192.168.1.1 was allowed. Original message below. Cheers.

On my Sequoia system, both Chrome, Safari, and curl (terminal) are unable to connect to 192.168.1.1.

At first I thought it was Little Snitch, but I've disabled that completely. I've also checked the Privacy & Security settings and have enabled the sliders for Local Network Access. When Local Network is disabled, Chrome reports that it is unreachable. When enabled, Chrome reports a time out.

I can ping 192.168.1.1. Traceroute also returns.

I can open other IPs in the range (.2, .3, .4, etc) but .1 never resolves. On may iMac running Ventura, .1 works fine.

All user accounts on this machine have the same symptoms. I can't figure out what is blocking the requests. I'm stumped.
