Dual Page Sync

For those who want to compare original and translated versions of foreign development documentation and various other documents side-by-side: • View two browser windows at once and scroll them together to compare original and translated text • New "Split Tab Mode" lets you view and sync two pages inside a single browser tab • Split Window preserves your logged-in session, cookies, and browsing context, so sites that previously rejected being reopened in a new window now work • URL sync keeps both windows navigating together when you move to a different page (can be disabled) • Scroll sync lets you manually adjust position anytime if it drifts • Choose between percentage-based default scroll mode and element-based (XPath) sync scroll mode, with improved alignment accuracy on pages of different heights • If sync disconnects while doing other work, the Reconnect button restores the link • Hide the control window, or end sync entirely via the × button • Split Tab Mode now has an Exit button to leave split view while staying on the current URL • Split Tab Mode now works on many sites that previously blocked iframe embedding through X-Frame-Options or CSP headers. Some sites (Google Drive, Gmail, Figma, and others using JavaScript-based frame protection) still restrict embedding in ways the extension cannot bypass
