Sizelock — Font Size Memory Autor: Nettie

Small text on news sites. Oversized fonts on old blogs. Resizing every time you visit is friction you shouldn't have to deal with.

Sizelock remembers exactly how you like each site — and silently sets it every time you go back.

What is does:

🔡 Per-domain font scaling — each website gets its own size, stored separately
⚡ Instant application — size is applied before the page renders, no flash of unstyled text
📋 Saved sites list — see every customized site at a glance, delete overrides individually
🔄 Quick presets — jump to 80%, 90%, 100%, 110%, 120%, or 150% in one click
🔒 Works entirely offline — no servers, no accounts, no data leaves your browser

How it work:

1. Visit any website
2. Click the Sizelock icon in your toolbar
3. Press A+ or A− (5% steps) or pick a preset
4. Done — the size saves automatically and applies on every future visit

To remove an override, click Reset or × next to the site in the saved list.
