Great app but sometimes it causes FF to want to open every new tab as a container.

Love this. Down with Facebook! Thank you Mozilla, very cool! But there's some slight performance hit on Messenger.

(EDIT: Apparently this bug is already fixed)

Used this for a long time but it recently started breaking certain websites. Changes text colour and page zoom for whatever reason.

I'll be using the DDG extension which something similar.

same, wrong colors on websites now

It seems to do a good job, but recently it affected the styling on websites. E.g. dark mode no longer changes text to a brighter color, making them illegible on some sites.
For this reason I have to disable it.

Le he seguido los pasos a esta extensión y puedo afirmar que realmente evita la intromisión de los dominios de Facebook en los otros sitios que visitamos. El trabajo lo hace en segundo plano, por eso pensamos que no hace nada la extensión. En realidad si optimiza la fluidez de los sitios porque no funcionan los scripts de facebook durante la navegación.

I don't quite know what rating to give - no way to tell if FB Container actually "works" because I can't know if it truly stops FB tracking me. But I trust FIrefox that it DOES. That said, it's a pain disabling it to send online item listings (for sale) to my host website's FB account for publicity there.

Add whatsapp web in the container addresses too. Thanks!

Since adding facebook Container I haven't been innundated with emails from facebook. This helps keep my email box for more relevant messages.
