Text input is saved while you type. There is limited support for other types like number or selects, these are saved only upon submit of a form and will be restored when you formfill a a page.

Some webpages use complicated html/javascript magic that renders extensions like this useless.

I am open to suggestions for improvements and bug reports. It is not easy to cram the many functions this extension has to offer into the limited available real estate.

Some websites use advanced techniques and frameworks involving javascript that make it virtually impossible to capture user input in a generic way. On request I can add workarounds for popular websites/frameworks, please submit an issue and let me know for which website(s) capturing entries does not work (see built-in Help, Manual, Known Issues).

Recent update 2.5.6.1 contains a fix that improves storing entries for many popular javascript frameworks like the cke editor. This release massively increases the number of sites where it is able to store/restore your work.

Syncing settings using the standard synchronization mechanism would be no problem but syncing data (form history) would be impossible because of the 100KB size limit.
