Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

No matter what settings I change, I still can't get audio to play from Firefox. I can use other browsers and get audio so I know it’s not my computer. I’ve even tried to uninstall firefox and install the newest version with no luck on getting my audio issue resolved. If anyone has any advice for me, it’d be greatly appreciated

I take guitar lessons on line and the audio for the lessons has suddenly defaulted to muted and I can't unmute it even with repeated attempts. The speaker icon is x-d out. I've rebooted, gone out and back in to the site and tried it on another browser where it worked fine. Firefox is my preferred. What can I do?

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

Please explain why this page is not loading SiriusMX listening page

It has in the past. Now it all it comes up with a blank page.

Picture Verification is not working in Firefox. It works correctly in Chrome. When trying to access prosper.com, it continues to send a link to check pictures. When clicking on the correct pictures, it comes back a repeats another picture.

Your instructions for migrating passwords from Safari to Firefox are outdated, ex.: there is no "Preferences" option, and no "..." to export

My Safari version on Macbook Pro is: Version 18.5 (20621.2.5.11.8) And my Macbook Pro runs: Sequoia 15.5

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

channel 4 repeatedly gives me this message when i enter my e mail address. there is nothing wrong with the address. Sorry, something went wrong. Please try again or use a different browser. after dozens of attempts it has let me in for the last few days. Today it does not

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

Firefox can't connect to www.123greetings.com but Chrome can.

Hmm. We’re having trouble finding that site.
