This is a very simple extension but an invaluable tool to quickly ascertain the quality and reputation of news sources being shared on social media platforms like reddit, lemmy, bluesky, mastodon, etc. I can't imagine browsing the internet anymore without it.

Is nothing like the original MBFC app that used to be really useful. All this one did was slow down Firefox, and cause it to crash. I know this because Firefox was telling me so with a unclickable blinking annoying "MBFC is slowing down Firefox".
So it's gone.

Icon in toolbar was flashing on Wikipedia. Unusable.

It's helped me avoid ideology-driven "news" sites on both the left and right.

The add-on reports "FN" (fake news) for websites that the MBFC website report as "mixed". It also reports "FN" on websites that aren't even listed on the MBFC website. It therefore CANNOT be pulling its information from the MBFC website; it's getting its data from somewhere else, and you can't trust whatever that source is, because it does not match the MBFC website.

This addon is fantastic! If makes it really easy to differentiate between trustworthy articles and non-factual ones before I even click on the link.

They are also very honest about each site. One of my top favourite sites has a very mixed rating which is not ideal ... but is very honest about their range of content.

If most people installed and used this extension, then this world would be a much better place. Everyone needs to install this!!!

Works great, thank you for the wonderful product!

I wish this addon would not collapse items on social media feeds. For instance, CNN shares on Facebook are collapsed, and regardless of whether I expand or collapse the item again, I cannot see who liked/reacted to the post, until I disable the addon in Firefox settings. So it's potentially two separate issues that I don't like with this addon. You can alert users to media outlets that don't meet certain criteria without collapsing anything, that's going overboard. And regardless, the addon should not interfere with the display of your likes, et al, on social media.

11 July 2022 update: I had a notification today on Facebook that someone had commented on ~my~ post (an article from the Guardian). I noticed when I posted the article that this Firefox addon had collapsed it but just ignored that. But when I received the comment notification today, and clicked on it, it just seemed to take me to a blank page. So I tried "hacking" the URL to remove parameters one by one, then I saw it was the collapsed Guardian post that received the comment, but I still saw no comment. Finally, I disabled this addon, and then I could see and read the comment. At the very least, affecting social posts should be a separate behavior from rating an actual website I am visiting, and an optional behavior that can be turned off (especially until it actually does not interfere with anything, and things like the "show anyway?" link can be see in, e.g., Facebook's dark mode (I keep dark mode turned off when I enable this addon, but I think I am going to disable the addon permanently instead, because I use dark mode everywhere.

In Twitter's dark mode can you change the font to white and remove the white background? :)

Good add-on for getting a rough idea about media sources.

However, they put the sites of Greenpeace and PETA on the "conspiracy" list alongside David Icke and Qanon.pub, which is kinda problematic.
