AI Is Flooding Microsoft Edge With Browser Extensions Faster Than Humans Can Check Them

Key points

• Microsoft's Edge browser team has publicly admitted that AI-assisted coding tools have caused a surge in extension submissions that is straining its review pipeline.
• Microsoft has introduced automated checks to replace many manual validation steps, though it has not confirmed whether those checks themselves use AI.
• The Featured badge for Edge extensions, which signals quality to users, will now refresh every 15 days instead of on a longer cycle.
• Microsoft has run multiple rounds of redundancies in recent months, leaving fewer staff to handle a growing workload.
• The Exchange email server team faced a similar bottleneck weeks earlier, also traced to AI-generated code volume.

Microsoft's Edge browser team has a candid admission: developers armed with AI coding assistants are shipping browser extensions so fast that the humans checking those extensions for safety and quality cannot keep up.

The team said in a post this week that "rapid adoption of AI-assisted coding" has allowed developers to build extensions faster than before and has pulled more developers into the ecosystem altogether. More creators plus faster output equals a much bigger pile of submissions waiting for approval.

That pile is a problem.

Why does this matter to anyone who uses a browser?

Before an extension, a small add-on that installs inside your browser to add features like ad blocking or password saving, appears in the Edge Add-ons store, Microsoft checks it for security risks and policy violations. More submissions mean longer waits for honest developers and, potentially, more chances for something harmful to slip through if corners get cut.

Microsoft says it introduced a fast-track review path earlier to ease the pressure. It has not eased. "Submission volumes have continued to increase, and our review pipeline has experienced additional strain, causing an increase in extension review turnaround time," the team wrote.

The workforce situation makes this harder. Microsoft has carried out repeated redundancies over the past year, which, as The Register first noted, leaves fewer reviewers to handle a pile that keeps growing.

What is Microsoft doing about it?

The short answer: more automation. The team says it has added automated checks for repeatable tasks, things like spotting known policy violations and obvious security red flags, so human reviewers can concentrate on complicated cases that need actual judgement.

Microsoft insists the standards have not dropped. "This doesn't change our review standards or reduce the checks an extension must pass," the Edge team wrote.

The company also says the changes will make the Featured badge more useful. That badge marks extensions that follow Microsoft's best-practice guidelines. It will now refresh every 15 days, so a developer who improves their extension earns recognition sooner, and users see a more current picture of what meets the quality bar.

It is worth being honest about what this story does not tell us. Microsoft has not said how accurate its new automated checks are, or what share of edge cases they might miss. Automation catching bad extensions faster is good. Automation creating new blind spots is a real risk that only time and transparency will reveal.

This is also the second Microsoft team in as many weeks to make exactly this admission. The Exchange email server team flagged the same squeeze a few weeks ago, blaming AI-generated code for a bug-finding backlog.

One honest takeaway: if you install Edge extensions, stick to ones that carry the Featured badge and have a solid track record of reviews. A busier review pipeline is not a reason to panic, but it is a good reason to be a slightly more careful shopper.
