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.

Why do you want to do this? Are they your own pages? –  ChrisF Oct 5 '11 at 12:44
Yes, they are my pages. Does it make any difference? –  thomas Oct 5 '11 at 12:46
Yes - you should spell check the content in what ever program you are using to create the web pages. –  ChrisF Oct 5 '11 at 12:47
I pull in content from a few different files to build up each web page. I'd like to do a check of the pages displayed to make sure I haven't missed anything. –  thomas Oct 5 '11 at 12:52

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.
You may have to drag-select the content of your page to force refresh spell check on the website's content.

Works in Chrome.

This plugin is insanely slow for long content. –  Calmarius Nov 23 '12 at 12:35
