I'm really bummed to hear the dev is shutting down this addon, as it's been one of my go-to addons I've relied on for years. It provides much needed functionality for those that use a tonne of tabs.

As much as I really want it to carry on, I 100% support the dev's response. Not only does the dev using 2FA not provide any meaningful security for us users, It's absurd that after years of trusted developer provenance/relationship with this dev/addon and Mozilla, Mozilla is now suddenly saying "Give us your phone number or G.T.F.O.", forcing him to walk the plank.

Go google what's been happening with Oculus VR headsets, and what Facebook now demands from owners. You not only have to have a Facebook profile, you have to *maintain* it so that it's current, with legitimate information, and if Facebook thinks you've used fake information, they'll instantly lock you out of your Oculus until -- no joke -- you submit to them pics of your government ID's, like driver's license, passport, birth certificate, utility bills, etc. And even then, some people have reported still being denied, or at least deemed not yet sufficient enough in Facebook's eyes.

They will literally brick your fully bought and paid for VR headset if you don't surrender to them some serious privacy. I didn't believe it when I first heard of it, thinking it was too crazy. But alas, it's true. Absolute insanity. Straight out of "1984".

I see other reviewers mentioning that a phone number isn't required for this 2FA. I don't know Mozilla's 2FA specifics, but if that is the case, I'd feel much better about Mozilla requesting/demanding this measure.

Regardless, it's getting ridiculous how these companies are increasingly demanding more and more sensitive information from us: phone numbers, documents, ID's, certificates, etc. All in the name of "security".

The irony in this? In the past 15 years, I've been "hacked" more times indirectly by these numbskull companies and their obscene lapses and deficiencies in security than I have from any weak passwords or security questions or whatnot on my end. And yet they get hacked, then turn around and demand even more from us, followed by another news story months down the road that they've allowed our data to get stolen out of their hands because they stored everything in plaintext, or didn't secure this or that.

And of course they get off scot-free, no repercussions, besides perhaps providing us some "Free credit monitoring!" I have enough "free" credit monitoring from hacked companies to last me three lifetimes. I'll be monitoring my credit from the Shadow Realm at this point.

Anyway, I hope the dev reconsiders, this has really been a fantastic addon.
