Quick Answer
Definition
Browser support FAQ is a short-answer page for common Jubal copy, paste, rights, and privacy questions.
Summary
Browser support changes over time, so the product uses feature detection and fallbacks.
Key Facts
- Why does localhost work differently from production? Localhost is commonly treated as secure for development, but embedded browsers and privacy settings can still block clipboard access.
- Why is Share not always visible or successful? File sharing depends on browser, operating system, permissions policy, and installed target apps.
- Is PNG required? PNG is the safest copy baseline for this product because browsers that support image clipboard writes commonly support image/png.
- Evidence and source links appear when a claim needs external support.
Rules
- If a browser or app blocks image paste, then use Link, Open, Share, or Download.
- Use the direct answer first, then open the related guide when you need steps or evidence.
- Use fallback actions when a browser or destination app blocks image paste.
- Use the contact page for rights, correction, or privacy concerns that need a human response.
