WideFix: Readable Websites on Wide Screens

About

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
