The containers feature was introduced before ETP started isolating third-party cookies and site data by default. You only need to use containers now if you want to do things like logging in to multiple accounts on the same site at the same time.

It's good to have something to stop trackers like Facebook. It should also be for other trackers.
The problem is that is breaks websites even if it appears to be disabled on the top bar. The Instagram feed on my website failed while it was working on Chrome, and it doesn't tell me that it was blocking it.
That is a problem for visitors using Firefox, it should not happen.

Don't work. Still gets facebook ads related to my Google search.

Not being able to run Facebook Container in private windows greatly limits the usefulness of this extension. I don't like being notified that some content creator shared my opinion with Facebook.

Latest version doesn't work - facebook.com only shows error: "Sorry, something went wrong."

Can't see that it's doing much of anything.

Like others reported, I found dark mode broken on many websites and tracked it down to this extension imposing some extra CSS. Baffling, please fix or revert!

Broke fonts on sites like steam and google translate. God I hate auto updates.

somehow broke text color and font on a bunch of websites. had to disable

Fonts on numerous websites are broken with latest update, making browsing experience horrible. Have to disable it and give 1 star until fixed, sorry.

Also seems to have slowed down tons of websites that have nothing to do with Facebook.

Changing fonts and colors of webpages... so pages that are darkmode now have dark text on top. Please revert this to an older version

With the latest update it changes color of fonts in some webpages

The update on 09/08/22 changes the font and font size on all pages, regardless of whether or not the page is using the extension. I've had to disable Facebook Containers until they fix this bug.

it messed up my font color
