Users: 1,000,000

Context-Aware Verdict

MEDIUM

Risk Level

Trust Factors: This extension demonstrates strong trust indicators with 1 million users, a solid 4.5-star rating from 4,000 reviews, and comes from PrintFriendly.com, a legitimate company specializing in web page formatting and printing services. The extension's purpose aligns well with its developer's core business, and the high user adoption suggests reliability and usefulness.

Concerns: The unlimitedStorage permission stands out as potentially excessive for a printing utility, as it allows the extension to store unlimited data on your device without clear justification. While the other permissions (activeTab, contextMenus, scripting, storage) are reasonable for a tool that needs to access web pages, modify content for printing, and provide right-click menu options, the unlimited storage capability could theoretically be misused for data hoarding. The extension's ability to access and process entire web pages also means it handles potentially sensitive content during the formatting process.

Recommendations: This extension appears legitimate and functional for its intended purpose. The risk level is moderate primarily due to the unlimited storage permission rather than malicious intent. Users can safely install this in their main browser profile, but should monitor storage usage if concerned. For highly sensitive browsing sessions, consider using the extension selectively or temporarily disabling it when not needed for printing tasks.
