About this extension
$5.99 is $6. Price Fixer finds charm prices on any web page and shows the number they are pretending not to be.

What it does
- Scans every price on the page — plain text, prices split across several elements (Amazon's "$" "5" "." "99", Walmart's superscript cents, Digikala's Toman icon) and content that loads later.
- Only charm prices are changed: .99 / .95 / .49 cents, whole amounts ending in 9 ($199) and the same at thousands scale (999,000). Round prices such as $12.00 or $500 are never touched.
- Highlight mode (default) shows the honest price with a green highlight; hover it to see the listed price and how little was actually taken off. Replace mode swaps the text silently.
- Nothing is destroyed: every change is recorded and Show originals puts the page back exactly as it was.
- The page's own scripts keep working — the price element's text is just the honest number.

Supported prices
- Symbols before or after the number: $ € £ ¥ ¥ ₹ ₽ ₩ ₺ ₪ ₫ ₴ ₸ ₱ ﷼ and more — $5.99, 5,99 €, ₹499, ¥99.00
- ISO codes and words: 299 EUR, USD 12.99, RMB 5999, Rs. 499, 99元, 1.999円, 49,99 zł, 299 kr, ۱٬۲۹۹٬۰۰۰ تومان
- Number formats: 1,234.99 / 1.234,99 / 1 299, Persian and Arabic-Indic digits. Output keeps the page's own separators, digit script and grouping style.
- Numbers without a currency marker are never touched, so dates, phone numbers, order IDs and "save 25%" stay as they are.

Using it
- Toolbar popup: global on/off, per-site on/off, Highlight/Replace mode, Rescan page, Show originals and a list of what changed.
- Ctrl+Shift+P (⌘⇧P on macOS) toggles the extension.
- Rules: ignore elements by CSS selector, ignore text by regex, or add your own price patterns.

Firefox does not grant site access automatically. If the popup says the extension is not active on a page, click Enable on this site.
