User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:136.0) Gecko/20100101 Firefox/136.0

Steps to reproduce:

Update to the latest FF build and go to https://www.hotstar.com

Actual results:

Page no longer works - same site works in Safari, Chrome etc

Just for laughs I downloaded Mullvad browser (based on FF) and that's broken as well

Expected results:

Page should have loaded

The Bugbug bot thinks this bug should belong to the 'Core::Networking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for reporting! To help diagnose this issue better, please can you:

1. Type "about:support" in Firefox and copy-paste its contents here
2. Does this reproduce in a clean profile or Troubleshoot Mode?
3. Capture a log when the issue occurs:

• In Firefox, ideally freshly started with no other tabs, go to about:logging in a new tab
• Select the Media preset
• Enable "stack traces for log messages"
• Click on "Set Log Modules"
• Click Start Logging
• Reproduce the bug
• Back on about:logging, click Stop Logging
• In the new tab that appears with the Firefox Profiler web application, in the top right click the button to upload the profile
• Make sure hidden threads are included and upload, then share the link here or send privately to a Mozilla developer
  -See https://paul.cx/public/about-logging-presentation.webm for a video walk-through

4. If this used to work in an earlier version of Firefox, please do a bisection to find the exact change that caused this (https://mozilla.github.io/mozregression/)

Bug 1950565 should fix this. The fix is in nightly (and I think beta) and we are trying to uplift the patch into release.

You may want to confirm this fix works by trying nightly.

I can confirm Nightly works fine with the same settings carried across from FF
