Always Can Check Spelling

Seek out and remove all checkspelling="false" attributes. This restores default behavior, i.e., does not turn on spellcheck for text inputs.

This script simply removes spellcheck="false" wherever it is found in a document. It also adds an item to the monkey menu to remove those again if they are introduced in the process of using the page.

Note: This script simply restore default Firefox behavior, so text inputs are not marked for spell checking but you can turn on spell checking in such inputs using the right-click context menu.
