Problems With Firefox Connecting To Local Sites On My Network

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

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.
 
Firefox 131.0.2 was pushed out today. Might not hurt to update to see if the problem goes away.
 
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.
 
I have the same problem, but I don't see firefox in Privacy & Security / Local Network. Is there a way to add it?

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

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.
 
I just got an M4 Mini which is the first Mac I've had that can run Sequoia. It did this same thing to me. I searched around and found that you have to enable a setting to allow Firefox to access local network resources. Settings -> Privacy & Security -> Local Network. Checking Firefox in that list allows it access to local network resources but I've found it's flaky and seems to "forget" the setting and block access randomly (even though the setting remains enabled). Toggling it off and on seems to restore local access.

Quite a bumble on Apple's part implementing a new mechanism for security that does not work reliably.

On mine, Private Wi-Fi address is set to "Fixed" and I can still access local network addresses via Firefox, so try that because it can reduce tracking.
 
As every time for the past 3-4 years, I'll wait for more stable updates before I upgrade from Sonoma. Maybe at .4 again. I can't be bothered with these stuff every time. So see you in some months.

I have the very same issue with MQTT Explorer and Network radar being prevented from accessing the local network with every startup on 15.1.1. Going into Privacy and Security > Local Network and toggling the sliders for these two gets them back to accessing the local network.

Really hope this is being addressed with 15.2

It's that dreaded worst sort of issue - intermittent. Some days I'll start up the Mac and Firefox can access local resources. Other days it behaves as you've described and toggling that setting "fixes" it.
 
I have run into this same problem with Firefox and Mac OS Sequoia. I have found that after powering on my Mac Mini or restarting it, Firefox is not allowed access to a server on my local network. Under the Privacy and Security section, the slider to enable Firefox local access is on (green), but I still have no local access. I have to turn the slider off, then back on to enable local access. I have to do this each time I restart the computer. It is definitely a bug that I hope gets fixed in the next OS update.
