Parallel Scroller

Parallel Scroller helps compare two regular web pages by linking their scroll position and offering visual QA tools for two-tab review.

What to include in a support request

• The extension version shown in Chrome
• The two page URLs being compared
• The sync mode being used: pixel or progress
• Whether the issue happens while picking tabs, scrolling, reloading, or comparing headings
• The exact error message or a screenshot

Common checks before reporting an issue

• Reload the extension in chrome://extensions
• Use regular http:// or https:// pages, not Chrome internal pages
• Try progress mode if the two pages have different content heights
• Refresh the SEO heading comparison after the page content changes
• Disable the page overlay if it interferes with visual inspection
