Absolute Zero

Tell the digit 0 apart from the letter O: renders every zero on a page in a slashed-zero font. Off by default, per tab.

Absolute Zero helps you stop confusing the digit 0 with the letter O on websites. It quietly rewrites page text so every ‘0’ is rendered with a slashed-zero font, while keeping the original layout, size and colors intact. This is especially useful on government portals, banking sites, license plates, serial numbers and any place where a single wrong character can cost you time or money. Features: – Off by default, enabled only on the tabs you choose – Works on dynamically loaded content (infinite scroll, single-page apps, etc.) – Leaves inputs, code blocks and editable areas alone so you can keep typing normally – Minimal footprint: only touches the digit 0 in regular text Absolute Zero does not send your data anywhere; all processing happens locally in your browser.
