  • Latest version

    Version 1.4.0

    Released Nov 12, 2026 - 10.91 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • New: FreeCorrector now checks Google Docs too: mistakes underlined in the document, one-click fixes, "Fix all" (Ctrl+Shift+F), and Ctrl+Z to undo.
    • New: a French verb conjugator: every tense of any French verb, with negative, pronominal, compound tenses, questions and feminine forms. Open it from the toolbar menu ("Conjugate a verb") or from the bubble of a conjugation mistake.
    • Far fewer false alarms on carefully written text, in English and in French, and the right fix shown first more often.
    • Many fixes thanks to your reports. Thank you!

    Version 1.3.0

    Released Nov 8, 2026 - 10.88 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • New: the FreeCorrector icon turns grey on a page where checking is off (site turned off, checking turned off everywhere, or the Ctrl+Shift+1 shortcut). An idea from a user.
    • Even lighter: the French and English engines each give their memory back as soon as they are not needed, even while the other one keeps working.
    • Many fixes thanks to your reports, in French and in English ("I think it's time" is no longer flagged, "profils" suggests "profiles", "excel" suggests "Excel"…). Thank you!

  • Version 1.2.9

    Released Nov 4, 2026 - 10.87 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • Lighter: after 3 minutes without typing, FreeCorrector frees its memory (about 45 MB at rest instead of 300) and only loads the engine for the page's language.
    • Many more mistakes found in careful writing (essays, cover letters, letters, reviews, recipes) in English ("to sad", "was build", "assist to the meeting"…) and in French.
    • The badge no longer covers the text or a search bar's button; scrolling boxes (ChatGPT) and X direct messages work better.
    • New shortcut Ctrl+Shift+1: turn FreeCorrector on or off for the open page.
    • Many fixes thanks to your reports. Thank you!

  • Version 1.2.8

    Released Oct 31, 2026 - 10.86 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • New: FreeCorrector underlined nothing, yet there was a mistake? Select the sentence, right-click, "Report a missed mistake".
    • Much better with everyday messages (texts, Discord, forums, ads, reviews): far fewer false alarms on informal language and more mistakes found.
    • French: the traditional spelling is offered as a style hint for the 1990 reformed forms ("parait" → "paraît"); one click turns it off.
    • English: many more mistakes typical of non-native writers found ("he can goes", "I did a mistake", "too much bugs"…), and names typed in lowercase ("greek" → "Greek").
    • Several fixes thanks to your reports. Thank you!

  • Version 1.2.7

    Released Oct 25, 2026 - 10.54 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • New: a "Report" button in the bubble, to tell us when a correction is wrong. You see and can edit what is sent; nothing leaves without your click.
    • A welcome page at install, with a field to try it and the useful settings (turn off on a site, dictionary, shortcut).
    • Many more mistakes found in English and French, and fewer false alarms: no final period asked for in chat messages, titles and lists.
    • The extension's version is shown at the bottom of the options; easier-to-read buttons in dark mode.

  • Version 1.2.6

    Released Oct 21, 2026 - 10.52 MB
    Works with firefox 140.0 and later, android 140.0 and later
    • FreeCorrector is also available for Thunderbird: your emails are checked as you write them.
    • When you reply to an email (Gmail, Thunderbird), the quoted message and the signature are no longer checked: only your own text is.
    • No more badge on sign-in forms: user names, email addresses, passwords and codes are never checked.
    • "Turn off on this site" now also covers embedded frames from other sites (sign-in boxes, widgets).
    • Short English texts are recognized better ("Bodies list incoherent display" is no longer checked as French).
    • Fewer false alarms: no capital letter asked for after a name like "JavaScript" at the start of a sentence, and in French.
