Common questions
What does Plumb inspect?
Plumb focuses on visual layout information: dimensions, margin, padding, gaps, position, alignment, Flexbox, Grid, element distance, rulers, guides and structural outlines.
Does Plumb upload the pages I inspect?
No. Plumb is designed so its core inspection work happens locally in your browser. See the Privacy Policy for the full explanation.
Why doesn't Plumb work on a Chrome internal page?
Chrome blocks extensions from running on certain protected pages, including pages such as chrome://extensions. This is a browser security restriction rather than a Plumb error.
Can I use Plumb on dynamically changing websites?
Yes. Plumb 1.0 includes handling for modern dynamic pages and single-page-app navigation, although individual sites can have unusual structures or protected frames.
Why can't Plumb inspect inside some embedded frames?
Cross-origin iframe boundaries can prevent a browser extension from accessing the document inside an embedded frame. Plumb handles these boundaries safely instead of attempting to bypass browser protections.
How do I clear a locked selection?
Press Escape while using the element inspector. The popup and on-page controls also provide access to inspection state.
How do I measure between two arbitrary points?
Use Pixel Ruler mode. Drag between two points and hold Shift when you want to snap the ruler horizontally or vertically.
How can I report a bug?
Email messageme@husseinakl.com with your Chrome version, the affected webpage if you can share it, and steps that reproduce the issue.
