Firefox Support Forum

Hi there I love FireFox, after years of others recommending, I finally switched and really appreciate so many great features (automatic downloads not at all though). Anyways, I have a Tivo with in house and out of house streaming to Watch Tivo web app and Tivo android app. Until recently, was able to stream anything from Tivo Box throughout house. Android app works awesome, but no longer working on FireFox (or Edge & Chrome) Research shows this is due to a change in website security which is maybe similar to FF issue?

Chrome offered advance warning/remedy..as detailed below....

I am hoping FF team can rise to the challenge and get tivo online working again for the millions of us who still use and love our Tivos.  Or maybe another Tivo fan has a workaround they can share? I sure hope so, I have wasted hours already troubleshooting and hair pulling :(     Any and all assistance appreciated

Access to XMLHttpRequest at 'http://(MYIP):49152/sysinfo/json/svcinfo' from origin 'http://online.tivo.com' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `private`.

After researching that i found this link Chrome CORS error on request to localhost dev server from remote site

it went into a bit about how "Chrome has implemented CORS-RFC1918, which prevents public network resources from requesting private-network resources - unless the public-network resource is secure (HTTPS) and the private-network resource provides appropriate (yet-undefined) CORS headers."

So basically a public network "online.tivo.com" cannot access my local network (where my tivo is) due to this new CORS-RFC1918 standard.

The is a fix to disable this behavior for now chrome://flags/#block-insecure-private-network-requests

I use a telehealth website to see patients (securevideo.com). The chat bubble on that website is blocked. I already spoke with their tech support and made sure I set my firefox privacy & security settings to standard, and I whitelisted (I think) the site on all my add ons (Disconnect, Ghostry, uBlockOrigin, Duck Duck Go). I also use Addblock Plus and Smart HTTPS but don't think they are relevant. SecureVideo.com's tech support said I should speak with Firefox support to find out why it is blocking their chat support bubble from showing on the site. What do I do? Also, how do I reach Firefox support directly if I can't get the help I need here? Thanks!

You keep saying you fixed this problem and obviously you didn't. Firefox will not let me sign into starbucks.com. Keeps saying sign-in unsuccessful. Site works perfectly with safari.

Firefox does not display custom fonts for any website online or webpage offline. This has been going on for months from update to update and I'm unable to fathom what could be wrong. I recently uninstalled the browser completely wiping out every folder or file that was remotely connected to Firefox and Mozilla. But on a clean reinstallation the problem persists. I'm using Windows 10 and I've had no font display issues with any other browser. To be honest, I've had font display issues with Firefox for years with any number of my own custom fonts refusing to display in it online and offline. I chalked it up as some corruption in those font files Firefox and no other browser was sensitive to. But this is something way beyond that. Any clues?
