Find & Replace All mnewton توسط

Find & replace ALL text on any webpage.

• Full regex: capture groups, named groups, lookahead, i/m/s/u flags — or plain literal mode.
• Substitutions: $1…$99, $& (whole match), $` / $' (around the match), $<name> (named group), $$.
• Variables: use {{name}} in the replacement; define your own — values can be plain text or JavaScript.
• Inline JS per match: {{= expr }} with match, g1…g9, groups, named, offset, i in scope.
• Built-ins: {{date}} {{time}} {{datetime}} {{url}} {{host}} {{title}} {{rand}} {{i}} (match number).
• Optional scopes: input fields & textareas, attributes (title, alt, placeholder, aria-label).
• Count dry-run, multi-level undo, settings synced.

No background worker and no host permissions: it runs only on the tab you act on (activeTab).

Example — find (\d+) and replace with {{=Number(g1)*2}} doubles every number on the page.
