Spanish Dictionary is an extension for Firefox that adds a spell checker to the browser, which scans text and shows possible alternatives for each misspelled word.
From the browser (in this case for Firefox users ) it is usual to comment on blogs, forums, online diaries, social networks like Facebook or Twitter, etc., or write emails (in web clients from the browser or using the mail client Thunderbird ); And to commit involuntary spelling mistakes (mistakenly typing), or to try to write fast and ignore the tildes, or simply out of ignorance.
The check mark ( underlines in red) misspelled words, and when you right-click on them you can see a list with suggestions, to replace them. Allows you to add marked words to the dictionary so they do not appear again as misspellings.
This plug-in also has support for other languages, such as English or German, so when you have to send an email in English you will be able to apply the proofreader.
Spanish / Spanish Dictionary 1.7 is the latest version of this Spanish-language proofreader for Firefox and other Mozilla applications, such as Thunderbird or SeaMonkey. You can download it for free.
