Rating: 2.0 ★ (1 rating)

Users: 264

Context-Aware Verdict

HIGH

Overall Risk

Trust Factors:

The extension has very limited adoption with only 264 users and a concerning 2.0-star rating from just one review, indicating poor user satisfaction. The lack of developer information and company details raises transparency concerns. The extension's purpose as a Twitter/X list scraper is legitimate but niche.

Concerns:

The webRequest permission is particularly concerning as it allows the extension to intercept and potentially modify all network requests on Twitter/X, going beyond what's typically needed for simple list scraping. The broad host permissions for both twitter.com and x.com domains, combined with unlimited storage capability, create a powerful surveillance toolkit. The storage permissions could be used to collect and retain extensive user data indefinitely. The low user rating suggests potential functionality or security issues that existing users have encountered.

Recommendations:

Given the high-risk permissions and poor user feedback, consider running this extension in a separate Chrome profile to isolate it from your main browsing data. Before installation, verify that simpler alternatives exist for Twitter list management. If you must use this extension, regularly review what data it has stored using Chrome's extension management tools. Monitor your Twitter account for any unusual activity after installation. Consider whether the functionality truly requires such extensive permissions, as many list management tasks can be accomplished through Twitter's native interface or less invasive tools.
