WideFix: Readable Websites on Wide Screens

WideFix keeps websites from stretching across your whole monitor. Many sites are comfortable on a laptop but become hard to scan on a large or ultrawide display. Lines get too long, feeds feel scattered, and content can sit awkwardly from edge to edge. WideFix lets you set a comfortable page width across the web, then make exceptions when a site needs different behavior. Use the popup for quick changes on the current tab. Use the settings page to review every saved override and fine-tune advanced rules. Features: - Set one global default max width - Override the width for a specific domain or exact page URL - Disable width limiting for sites or pages that should stay full width - Enable WideFix only when `window.innerWidth` is above your chosen threshold. Useful if you switch between a laptop and an external display. For example, you can keep WideFix inactive on your laptop-sized browser window and automatically enable it when the window is wide enough on your desktop monitor. - Add custom CSS at the global, domain, or page level - Optional faster User Scripts mode for earlier rule application - Review all domain and page overrides in one place Rules apply in this order: 1. Global default 2. Domain override 3. Exact page URL override Custom CSS is layered in the same order, so you can start with simple width control and add site-specific tweaks later. Good for: - Ultrawide and large desktop monitors - Reading text-heavy sites with long line lengths - Centering layouts that feel too stretched - Keeping a few sites full width while narrowing the rest of the web - Switching between laptop and external monitor setups
