Google just gave Chrome extension developers a deadline and a long list of things they’re no longer allowed to do, thanks to Chrome’s Malicious and Prohibited Products Policy.
The company announced new Chrome Web Store rules for developers this week that limit what extensions are allowed to collect, enforce clearer disclosures, and put an immediate ban on entire categories of tools. Developers have until August 1, 2026, to comply. After that, enforcement kicks in.
What’s actually changing
Extensions can only collect data that’s necessary for the task they claim to do.
No more grabbing extra user information in any case, even if a future feature needs it. Moreover, if a developer changes what their extension collects after you’ve already installed it, they now have to tell you, not just bury it in an updated privacy policy that nobody bothers to read.
Two categories of extensions are gone completely. Anything that helps facilitate real-money betting on prediction markets is banned. This means no more wrapping a betting site in an extension and calling it a browser tool.
Moreover, anything designed to jailbreak AI chatbots is no longer allowed on the store; this includes tools that purely exist to help you get around a chatbot’s safety limits or circumvent usage limits.
Over the course of the past few years, I have installed a few AI-related sidebar extensions without thinking twice about what they were quietly logging and how my data was being handled.
Turns out that instinct wasn’t wrong.
Just last month, researchers found extensions impersonating a popular AI sidebar tool that were secretly extracting full ChatGPT and DeepSeek conversations to outside servers every thirty minutes. You won’t believe, nearly a million people have installed them.
Does this fix the problem?
Policy changes only work if Google truly enforces them.
The Chrome Web Store has always had rules against sketchy data collection tactics, yet plenty of malicious extensions still slipped through the cracks; some even earned a “Featured” badge while quietly stealing chat logs in the background.
Despite all this, closing the jailbreak loophole matters.
Those tools existed for one reason only, i.e., to strip out the safety work companies put into their AI chat products. Banning them outright is a clearer line than anything Google has drawn before.
If you happen to use Chrome extensions, especially anything that touches your AI chats, this is a good week to open chrome://extensions and look at what you’ve installed on your Chrome browser.
Yes, you need to perform a proper audit. Check what permissions you granted. If you don’t recognize something or can’t remember why you installed it, that’s your answer about what to do next with that extension.
