InputCleanup de Lupus Inflamare

This add-on allows the user to apply a set of custom-defined replacement rules to the text of an input field on a website. When opened on the current tab, it searches for an active input field (such as an input element or a content-editable field) and reads its content. The user can then apply predefined replacement rules to the extracted text. Manual adjustments are also possible. The result can optionally be written back into the active input field or copied to the clipboard. The rules can be exported to a file or imported from a file. Regular expressions are supported.
