WARNING: New Firefox feature WILL break SQRL

  • SpinRite v6.1 Release #3
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

Firefox recently implemented and even promoted a new feature for HTTPS Only mode. Stupidly, they make this apply to localhost connections as well... If you enable this setting it will completely break SQRL login.

@Steve, you may want to note this on the podcast.

I made a warning graphic, which I stuck here https://snipboard.io/x3vck6.jpg

but will also paste here:
Official annoucement:

I really doubt they will keep this moving forward to an official release without any backlash. That would break countless tools everywhere, not just SQRL. Off the top of my head... every domestic Wi-Fi router? Pretty much every IoT device in the market?

Changing this behavior needs to be followed by a clear standard on how to handle ad-hoc, isolated use cases. Maybe a defined standard on how to handle auto-generated self-signed certificates?

I'm curious to see the outrage if this ever makes into an official release without further consideration.
