- Wouldn't let me create a custom theme without creating an account and publicly publishing it. I tried to delete my account and data since I won't be using this anymore, but there is no way to do so.

- **URGENT WARNING: Uninstall the Stylish Chrome Extension NOW—It’s Spyware Linked to Israeli Data Harvesting** The Stylish browser extension, once a popular tool for customizing website appearances, is **actively spyware**. In 2018, security researchers and users exposed that Stylish was **secretly logging every website you visit**—including sensitive pages—and sending that data to servers controlled by **SimilarWeb, an Israeli digital intelligence firm based in Tel Aviv**. **Evidence You Need to See:** - **Independent security researcher Robert Heaton** published a technical breakdown showing Stylish **exfiltrating full browsing histories** to SimilarWeb’s servers. His network traffic analysis proved the extension was **stealing URLs in real-time**, not just collecting anonymous analytics. - **Google and Mozilla removed Stylish** from their official stores after the scandal, confirming its malicious behavior. - **Xinhua News Agency** reported that Stylish, owned by SimilarWeb, was pulled for “privacy violations and private data collection,” with 2 million users affected. - **Reddit’s privacy community** sounded the alarm, with users confirming the extension’s new privacy policy was a thinly veiled attempt to legitimize mass surveillance. - **Hacker News discussions** revealed that browser extension developers are frequently approached by companies offering cash for user data—Stylish was a prime example, with users’ browsing habits sold for profit. **Why This Matters:** - SimilarWeb, Stylish’s parent company, is **headquartered in Israel**, a country with a controversial reputation for digital surveillance and intelligence operations. - The extension’s permissions allow it to **“read and change all your data on all websites”**—a red flag for any privacy-conscious user. - Even after being reinstated, Stylish’s history proves it **cannot be trusted**. The open-source community abandoned it en masse, creating the safer alternative **Stylus** to escape SimilarWeb’s data dragnet. **Action Required:** - **Uninstall Stylish immediately.** It is not just a privacy risk—it is **active surveillanceware**. - Switch to **Stylus**, the community-backed fork that respects your privacy and offers the same features without the spyware. - **Never trust extensions with broad permissions**—especially those linked to data brokerage firms like SimilarWeb. **Your browsing history is not for sale. Protect yourself—remove Stylish now.**
