it creates H1 to all pages with the phrase: "Facebook Container" should not interfere with the original page document outline at all. ???

Confused with "Allow Site in Facebook Container" and other that does not let me know that it blocks Facebook. It should have shown a red "X" on a popup :fence: icon so that I will know what that mean instead of an arrow icon. Another popup window on other website, "Allow Facebook to track you here?" This is a very poor statement without asking me for Yes or No. This is definitely needs to update version. We want the red "X" icon.

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

It blocks facebook, but now it leaves a button/icon on every website with this stuff included that I cannot move and that's generally very much in the way of all texts. This button is more annoying than Facebook which I don't use and have zero impact from (but I don't want to give them any data either, so hence no 1 star review). Would get 5 stars if I've never noticed it at all.

Man kann nicht mehr firefox container benutzen um in mehreren facebook accounts gleichzeitig eingeloggt zu sein, er erzwingt das tab im selben facebook container.

Great concept, but it breaks Facebook Workplace (won't sign in) so I cannot use it. Needs the option to whitelist domains, perhaps.

When activated, facebook is out but at the same time I'm unable to log to gmail or other websites (without using facebook-login dear trolls).
Gmail says that my browser is not secured and ask to install a recent one. Other websites ask for recaptcha and repactcha is unable to work properly when this add-on is activated.. This require to be improved.

It works on facebook but broke a few other websites.
Menu bar on the NY Times Coronavirus page (https://www.nytimes.com/2020/05/02/us/politics/vaccines-coronavirus-research.html) broke.
It also stopped mint.com from tracking my computer, so I had to authenticate with my phone every time. Both websites work when I uninstall the plugin and reset firefox.

worked okay for a few days but suddenly made facebook go into infinite reloads.

Ya no funciona en ventanas privadas 👎👎👎

Seems to interfere with loading messages. Whenever I switch it on then messenger will load all the oldest messages in the chat first before allowing me to scroll down to the newest ones. This makes it unusable so I've had to remove it.
