Firefox/Projects/View Source in Tab

From MozillaWiki
Jump to: navigation, search


  • View source currently opens in a separate window that doesn't share the browser UI or features and, being in toolkit, requires overlays to tack on Firefox integration
  • Link browsing currently feels incomplete since there's no way to open links in windows or tabs and back and forward are only available via the context menu
  • By opening in a tab, we get these features for free without duplication and they'd stay in sync with any changes made to them for normal browsing

Goals/Use Cases

  • Eliminate standalone view source window and replace with a content page
  • Duplicate current features (selection source, MathML source (or drop it?), go to line, line wrap) using only content script where possible

Non Goals

  • Line numbering
  • Better syntax highlighting


  • Source Viewer Tab: An existing addon for the purpose. This reuses chrome://global/content/viewSource.xul with little changes.
