I get the error message "Firefox can’t connect to the server at localhost:8090" when I try to connect. All other Internet sites load with no problems.

Any suggestions for a fix will be greatly appreciated.

Hello. I am trying to configure the necessary connection and proxy settings within Firefox to ensure stable web access. Could you please provide the recommended steps or official documentation links regarding network routing and connection preferences in the browser? Thank you for your guidance.

Hello. I am writing to ask for technical guidance regarding network connectivity and connection settings in Firefox. Specifically, I need to know how to properly configure proxy or routing parameters to ensure stable web access. Any official instructions, troubleshooting steps, or documentation links you can provide would be greatly appreciated. Thank you for your time and assistance.

I was cleaning my laptop screen and my firefox got disconnected in the process. I would appreciate help with re-establishing the Firefox application. Note: I can open my gmail email accounts, but note NEWSMAX-LIVE

I have found now a couple of times over the past month or so that I am blocked from accessing some websites. It has turned out that when i use Whatismyip or some other similar service, my IP address is incorrect. In one instance it had me in Germany and just now it had me in Dallas, Texas. I am actually in Mexico.

My first thought was that maybe it was an issue with my ISP, but it's not that. I can get a correct IP lookup if I use Chrome, but it's only when i use Firefox the IP address and location (even country!) is wrong.

I have the native FF VPN extension installed but not turned on. I also have Windscribe extension installed but not turned on. I very rarely use either of those VPNs (maybe 4 or 5 times a year). This is after a fresh reboot, so no "holdover" from a previous use of any VPN.

Anybody else seeing this behaviour, or have an idea how to fix it?

Running v.159.0 on mac laptop. Firefox repeatedly freezes, displaying a swirling 'busy' rainbow colored dot for several minutes, then reports: "There was a problem connecting with the server 192.168.0.1". In fact my router is not at 192.168.0.1, it's at a different 192.168 address. But why is FF trying to connect there anyways, and how to stop it? This problem began on restarting FF after I had shut it down with open tabs, which I do not normally do. Version may have updated to v.159.0 on the restart. Thank you for any help.

I think the behaviour is triggered by the mac in sleep mode and resuming browsing. The issue only affects as far as I can tell LAN pages. Been over the pages https://support.mozilla.org/en-US/kb/server-not-found-connection-problem?as=u&utm_source=inproduct

Another browser such as Safari or Chrome does load the page fine, but Firefox. Using the latest 159.0 but the issue I recall been around for a bit now.

Don't have proxy configured, disabled DNS prefetch, IPv6 support...deleted cache and cookies, restarted Firefox and no change. The only way I found to fix the behaviour by restarting the mac. Any ideas or thoughts on what could be going wrong here please?

(does it with home assistant, the synology NAS, and other LAN pages)

This is what I get when I try to go from an email to there site, why? This is something new.
