This add-on is a life saver when a site borks and removes the text you've drafted, or reloads for no apparent reason, or just decides to log you out. Couldn't live without it.

Just the thing for tax forms that might take days to complete but say:

"One-time submission

The online FBAR form does not allow you to save your progress during
form completion as it is designed to benefit filers who are ready to
file the FBAR today. If you have gathered all information needed to
complete and submit the FBAR in a one-sitting, then the online form
might be right for you."

Finally found something that replaces Lazarus completely for me. Textarea Cache didn't have dropdown list history, this one does.
