In-depth safety analysis
This extension requests permissions that are typical for a tool that finds and highlights words on web pages. The tabs permission allows it to read the URL of the active tab to apply highlighting rules. The storage permission lets it save your word lists and settings locally. The contextMenus permission enables adding right-click options to mark words. Notifications and alarms are used for reminders or alerts you configure, while the offscreen permission allows it to perform tasks like processing word lists in the background without a visible window. This scope is normal and expected for a highlighting utility.
As a general browser extension, the main safety consideration is that any tool with access to page content can technically see what you browse. A careful user should be aware that a highlighting extension needs to read page text to function, and should only install such tools from sources they trust. It is also wise to review an extension's privacy practices and permissions periodically, as updates can sometimes change behavior.
Based on the fact sheet, the strongest dimension is Maintenance and Ownership, indicating the extension is actively updated and well-maintained. The weakest is Publisher and Identity, which suggests the developer's background or public presence could be more transparent, though this is not uncommon for smaller or independent publishers.
