StableHTMLFinder

Compares multiple page loads and shows stable elements for building reliable selectors.

StableHTMLFinder helps you create reliable selectors for elements on modern, dynamically changing web pages. WHO IS IT FOR? The extension is useful for web developers, testers, automation engineers and anyone who needs to identify the same page element reliably after the page has been refreshed or updated. HOW DOES IT WORK? StableHTMLFinder captures several DOM snapshots and compares them. It then builds a visual stability map showing which elements and characteristics remain unchanged and which may vary between page loads. This helps you choose dependable tags, attributes, text and structural relationships instead of relying on selectors that may stop working after the next refresh. KEY FEATURES • Compare up to five DOM snapshots. • Build an interactive HTML stability map. • Identify stable and relatively stable elements. • Examine tags, attributes, text and relationships between elements. • Inspect elements inside iframes and Shadow DOM. • Search the map using HTML fragments and CSS selectors. • Generate selectors based on stable characteristics. • Save DOM snapshots and diagnostic page snapshots for further analysis. WORKS WITH BLOCKIT StableHTMLFinder also works well alongside BlockIt. You can use it to find stable characteristics of unwanted page elements and then create reliable BlockIt rules to hide or remove them.
