I love the IDEA of this extension, and the general goal of MBFC... but the extension, especially on the socials, is WILDLY out of sync. Worse, there seems to be NO mechanism to suggest edits or point out issues. A bunch of pages are marked as Left/Right or Far Right/Left, which are CLEARLY not, others are showing "Pro science" when they are NOT, and a bunch of others are reporting completely different sources from the person posting. Example: Filledelaspace, a space and science poster marked as Right (which is laughable) but looking at the report, it shows that poster to be a talk radio station in Kentucky - just OFF. Don't know if it's a database problem on the back end... something interfering with reports... or something weird, but there's very little info in the drop down, and no place to respond/comment. I have to uninstall the extension because it's just useless.

This extension makes Media Bias/Fact Check easier to use by showing the ideological bias as the extension icon in the toolbar and providing a direct link to the page about the news source. If the site is not rated by Media Bias/Fact Check, that's also immediately apparent since the icon does not change.

As a retired editor, investigative journalist, technical writer, I rely on Media Bias Fact Check as my primary go to for news-source analysis. I find MB to be accurate and reliable. I also publish this in-depth fact checking compendium: https://cfitampabay.org/a-compendium-offact-finding-sites/

I think this tool has an admirable cause, but like most tech it inherently leans left. If you shift all the bias ratings a half or full notch left you're most likely looking at an accurate picture. It's a good tool to get a quick glance but can be quite misleading if not used with discernment. The easiest way to spot this bias is if you do a side by side rundown on presidential candidates, specifically Joe Biden vs. Donald Trump. Under the key policies section one of them has their objective policies, the other has their objective policies plus subjective information thrown in there to discredit said policy. Nonsensical. If you pride yourselves on being the ruler in which to judge bias, examine yourself for said bias.

I think it works well, but the fact that it considers FOX NEWS as "questionable or fake news" on every article shows that this "media fact checker" clearly has a bias. I would rather seem them be fair and actually label Fox News are "right wing". Be consistent.

It pains me to give the extension a mediocre rating because it provides such a critically important tool, but it's strictly for technical reasons. I love its *purpose* and I fully trust the assessments it displays for news websites, because I've thoroughly vetted the same-named website on which those ratings are based. I find their (openly-published) methodology to be sound, and eventually even became a lifetime subscriber. But the extension failed me too many times, and I finally had to remove it several weeks ago. (I had to reinstall it to post this review.) The problem: I kept noticing that its icon had vanished from the browser. Each time, I went to the area where you manage extensions, and each time saw the message "This extension may have been corrupted," or something very similar. There was always a button to repair the extension, and clicking it always seemed to work.... but then it would happen again days or weeks later, over and over. This all happened on a desktop computer, on the Linux operating system. It happened in the Brave web browser, and I believe also in the Chromium browser. I don't have Chrome, so I can't speak to how well it works on that. I always have a HUGE number of open tabs, so I considered that might be the cause, but I have several other extensions installed which have never needed repairing. I've removed and reinstalled it several times, and have provided feedback about this a few times before posting this rating. I really feel I did my due diligence. Hopefully the problem is fixable, or at least rare. Meanwhile the MediaBiasFactCheck website also recommends a similar, third-party extension which provides the same service. (I won't name it because I don't want it to seem I'm only criticizing this one to promote that one, but you can find it for yourself at https://mediabiasfactcheck.com/appsextensions/ and as of November 2023 it's one of the alternatives shown here in the Chrome web store.)

Doesn't work on facebook anymore, doesn't run on chrome or firefox.

This is a tried and true sort to discover and understand the media that you are consuming. I believe in reading all sides of story and understanding where the "news" is coming from. I am a child of Brinkley, Cronkite and Rather. I am a consumer of NPR in my adult life. It still means I am going to check everyone's bias to better understand my own. Be curious...not judgemental! This extension is your resource to better information.

Media Bias Fact Check is an ESSENTIAL extension/web site to use in a world of misinformation and lies that ruin societies. If only everybody used this. Having used the web for 30 years and being politically aware, I can confirm that the information provided by MBFC is at least 95% correct.

I generally like this extension but I would rather have the social media bar and the description of why the site earned left-right, and factuality rating it did. Rather than a description of what the left-right-center description means when clicking the icon.

This is accurate. It even has Fox News down as FN (Fake News)😁

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