## Description

GitHub Resizer puts a slider in your Firefox toolbar that lets you choose <strong>exactly how wide</strong> GitHub pages should be - anywhere between GitHub's native 1280 px layout and the full width of your browser window, in 1 % steps.

Most "wide GitHub" extensions are an on/off switch: either you get the default narrow layout, or you get the full screen. GitHub Resizer answers a different question: <em>how wide?</em> Pick 25 % for a comfortable reading width on a 4K monitor, 50 % on an ultrawide so code blocks stay readable, or 100 % to fill the entire screen.

<strong>Features</strong>
<ul><li>Smooth slider from 0 % (default GitHub) to 100 % (full viewport) in 1 % steps.</li><li>Quick presets: 25 %, 50 %, 75 %, 100 %.</li><li>Live updates - your setting is applied to every open GitHub tab instantly, without a page reload.</li><li>Cross-device sync - your chosen width follows you to other computers via your Firefox account (<code>storage.sync</code>), with a local fallback.</li><li>Safe on small screens - on viewports up to 1280 px the extension does nothing, so GitHub looks identical to its default layout.</li><li>Works on modern GitHub - also widens the inner content column on the new Primer-based GitHub pages, so the page doesn't end up wide-on-the-outside but narrow-in-the-middle.</li><li>Keeps READMEs and other markdown content responsive instead of capping them at a fixed width.</li></ul>

<strong>Privacy</strong>

No tracking, no analytics, no network requests. The only thing the extension ever stores is a single number between 0 and 100 - your chosen width - in Firefox's own storage. Nothing leaves your browser except via Firefox's built-in account sync (if you have it enabled).
