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.
