Add-ons
FreeCorrector 1.2.5
by BenjiBurn
Free, open-source spelling and grammar checker for your emails, in English and French. Underlines your mistakes as you write and fixes them in one click. 100% local: your messages never leave your computer.
About this Add-on
FreeCorrector checks your emails as you write them, right in Thunderbird’s compose window. Free, with no account, no subscription and no ads.
How it works
• Mistakes are underlined as you type: red for spelling, orange for grammar, blue for typography.
• Click an underlined word to see the recommended fix, with the other suggestions right below.
• A counter at the bottom right of the message shows how many mistakes there are. Click it for the full list.
• Works in HTML and plain text, for new messages, replies and forwards.
Only what you write
In a reply, the quoted message, the "X wrote:" line and your signature are left alone: only your own text is checked. The message you send contains exactly what you wrote, with nothing added.
English and French
The language is detected automatically for each paragraph, so an email mixing both languages is checked in both. English: your/you’re, its/it’s, their/there/they’re, subject-verb agreement, tenses, “should of”, typos and more. French: agreement, conjugation, homophones, past participles, subjunctive, accents, capitals and punctuation.
Your messages stay yours
Everything is checked inside Thunderbird. FreeCorrector sends nothing over the Internet, collects no data and even works offline. Thunderbird itself blocks any network connection from the add-on.
Also
• Personal dictionary, with import and export.
• Picky mode for fine typography.
• A proofreader page (FreeCorrector button) to check a long text.
• Undo with Ctrl+Z after a fix.
Tip: to avoid double underlines, you can turn off Thunderbird’s own spell check as you type (Settings, Composition).
Open source
FreeCorrector is free software (GPL v3). It builds on two open-source engines, Harper for English and Grammalecte for French, and adds its own rules and context-aware ranking of suggestions. Also available for Firefox and Chrome. Source code: https://github.com/BenjiBurn/FreeCorrector
