(A) A significant percentage of users with legacy browsers could upgrade (by installing Chrome or Firefox, instead of relying on a woefully out of date bundled browser). If much of the internet stops working for them, I imagine knowledge of how to get it working again will spread pretty quickly.
(B) It seems incredibly difficult (impossible?) to support graceful downgrade to older insecure approaches to TLS without also introducing the opportunity for a downgrade attack.
Many of the TLS attacks we've witnessed over the last few years seem to be the direct result of bending over backwards to maintain backwards compatibility. I'm unconvinced it can be done safely.

(B) If someone can find a vulnerability to our implementation that we cannot fix then we'll drop support for SHA1 fallback. We'll also allow customers to turn off SHA1 fallback if they'd prefer. But that should be the choice of a site on a site-by-site basis, not imposed by the browser vendors.

- ploxiln 11y agoAmusingly, these users may not be able to download modern browsers from the official websites, which will of course be only available over TLS for obvious security reasons ...
- biot 11y agoYou mean as the article explicitly points out with "Mozilla's one million downloads mistake"? I'm not sure how that could be considered amusing.
- ploxiln 11y agoUnintended consequences. Unfortunate. But after you've seen enough of them, funny as well.
- brohee 11y agoWindows installers can and should be signed, since at least Wondows XP, so it can be safe to download a browser over an unencrypted connection...
