How can I spell check web pages when browsing them? I've added the After the Deadline Chrome extension, but it only seems to work on forms and not whole web pages. I'm happy to use Firefox if that provides a solution.
Use the bookmarklet from Switched.com: how-to-spell-check-any-web-site-using-firefox
You can drag-n-drop the bookmarklet link on your bookmarks bar.
Works in Chrome.
I can recommend SpellcheckEverything extension for Firefox. I’s very simple – it just forwards all the work to the spellchecker used for textareas in forms.
From SpellcheckEverything @ Mozilla Addons, with typos fixed:
Kudos to How can you check spelling on an existing webpage? @ Mozilla Support. Without that Q&A, I would miss this addon.
