# Social Preview Checker Browser Extension

Open LinkGlimpse from the toolbar and it automatically checks the current page. See social cards, a Google search preview, metadata diagnostics, image checks, redirects, and copy-ready fixes without leaving the extension.

[Add to Chrome](https://chromewebstore.google.com/detail/alhheglnjpjfiaehoekkndaogkfdhdga) [Add to Firefox](https://addons.mozilla.org/en-GB/firefox/addon/linkglimpse/)

Free to install. No LinkGlimpse account required.

## Automatic on open

Click the toolbar icon and the current page is checked immediately—there is no URL form or inspect button.

## Minimal permissions

Only the active tab and LinkGlimpse API—no browser history, cookies, credentials, or continuous background access.

## Everything in the popup

See the score, platform previews, metadata values, extracted tags, and copy-ready fixes without opening another page.

## Open source and inspectable

The extension source is public. Review its permissions, inspect the implementation, or build both browser versions locally.
