I like seeing this fence icon on various web pages I visit. I would suggest that a "disabler" be programmed because some time I want to share TO Facebook, but CAN'T because of FC.

Can anyone actually tell me if this works? I've had it for months and only ever once saw the container wrapped. It seems I just have it for a show and nothing else. Reinstalling does nothing. Resetting the browsew makes no difference. Can't remember what that time actually happened that it worked......

As of today, 28 Mar 2021, Facebook Container 2.1.2 is BROKEN for 78.9.0 ESR 64 bit. It worked in 78.8 ESR 32 bit, but locked me out after the upgrade. When I turn the extension off, Facebook reappears. Remove, restart, and reinstall doesn't help.
[edit] This version WORKS PROPERLY on 78.8.0 ESR 64 bit. I checked it on other versions running on my network, sync'd to the updated 78.9.0 ESR 64 bit.

Doesn't work

Had to remove this app. Could not get into some of my bank accounts.

Don't know what all the fuss is about, works fine with FF 86.0.1 on my Windows 10 machine. After listening to Snowden and reading The Intercept, this is a must-have extension. The future is private but certainly not they way FB or Google intend it to be! (and as a corollary, the intelligence community.) So be wise, be smart, and don't be used.
