Is TextOptimizer safe?

Medium risk

TextOptimizer exposes a UI that web pages can use to send active-tab page and form content to its APIs.

The extension's web-accessible textoptimizer.html can start an analysis flow that asks the active tab for selected text, or falls back to the page HTML plus visible input and textarea values. It posts that content with the page domain and language/search settings to api.textoptimizer.com, or to api.1.fr for French settings.
