YouTube appeared to be experiencing major problems for many users on Wednesday, but the platform itself wasn’t actually down. Instead, the issue was triggered by ad blockers, a recurring flashpoint in YouTube’s ongoing crackdown on third-party tools that interfere with ads. What looked like a widespread outage turned out to be a problem affecting only those using browsers with ad-blocking extensions enabled.
A blank YouTube homepage? Ad blockers are the culprit
Reports on DownDetector spiked early in the day, with thousands of users saying that YouTube was refusing to load properly. Some were met with empty homepages, missing thumbnails, or pages that wouldn’t scroll. Many assumed it was a server outage. But a pattern quickly emerged: switching to a browser without an ad blocker instantly fixed the issue.
Users who opened YouTube in Safari, Edge, or Chrome without extensions found the site working normally. But those using Chrome or Firefox with ad blockers enabled were stuck with broken pages. This strongly indicates that YouTube pushed out a new anti–ad blocker measure, or one of the extensions’ filter lists conflicted with YouTube’s scripts, causing the layout to break.
This is not the first time this has happened. Over the last year, YouTube has repeatedly tightened enforcement against ad blockers. Past incidents included videos loading painfully slowly, watch counts failing to refresh, and error messages prompting users to disable extensions. The latest wave appears to be a more aggressive response that prevents the site from loading at all.
A separate Shorts bug added to the confusion
Adding to the chaos, YouTube Shorts also experienced a brief UI glitch overnight. Users found that comments, like buttons, descriptions, and other interface elements disappeared entirely. That bug, however, seems unrelated and was resolved quickly on YouTube’s end.
This morning’s larger issue, by contrast, affected only those with ad blockers, and vanished the moment they were disabled.
For anyone still facing problems, the fix is straightforward: turn off your ad blocker, refresh the page, or try a different browser. YouTube should start functioning again immediately.
