A recent update to the popular cryptocurrency wallet extension MetaMask has caused a wave of trouble for Firefox users. The issues started popping up right after the release of version 12.12.0, leaving many websites broken and frustrating users who rely on the browser and extension combo. Reports quickly flooded in, with people seeing blank pages after logging into sites or trying to run searches.
According to complaints I found online, websites like DuckDuckGo, Mail.com, GitHub, and OpenRouter.ai stopped working properly. Users also flagged problems with qBittorrent and Pi-hole web interfaces, gaming giant Steam, and even The New York Times’ Wordle game. “DuckDuckGo just gave me a blank page when MetaMask was enabled,” said user DaveO-Home on GitHub. Many others also had similar issues.
The culprit behind this mess is apparently tied to how MetaMask handles the Content-Security-Policy (CSP) header. That’s a security feature websites use to block certain attacks, but version 12.12.0 messed with it in a way that broke compatibility. The result? Pages that wouldn’t load right, leaving users stuck staring at empty screens.
Good news is, there’s a quick fix you can apply right now. Head to MetaMask’s settings, click the three-dot menu in the top-right corner, and go to “Settings.” From there, hit “Advanced,” scroll down, and turn off the “Override Content-Security-Policy header” option. Users like firehawkx reported instant relief, saying, “Disabling that setting solved it for NYTimes Wordle and Steam.” It’s a simple tweak that gets things running again.
MetaMask’s team isn’t sitting idle. They’ve already confirmed the issue and are rolling out a permanent solution in version 12.12.1. That update is done and submitted to Firefox for review, though there’s no set timeline for when it’ll go live. “Let’s hope for a speedy approval,” said team member Gudahtt on GitHub. Until then, the workaround is your best bet, or you could disable MetaMask entirely if you don’t need it active.
For Firefox users caught in the crossfire, applying the fix or waiting for 12.12.1 should get you back to browsing without a hitch. Keep an eye out for that update — it’s coming soon to save the day.
