## Review summary

Users repeatedly report that the add-on reliably speeds up pages that pull resources from Google CDN (especially fonts), reduces crashes/long waits, helps Google CAPTCHA load faster, and can restore access to sites that previously wouldn’t open. No issues were reported by multiple users; isolated complaints (e.g., reddit login, lack of options) appear only once each.
