Would not be without it now
How many times have I had to retype a PM or a comment.
This little script helps with this problem

Need of course to have greasemonkey loaded
A little disconcerting sometimes, because you may see your last comment in a thread instead of seeing a blank box, so one may inadvertently load the same comment again
But one gets used to all that.
Saves a lot of anxiety and freezing tabs with TMP to try and not lose the page.
Remembers everything !
Gives the option to use or not to use the remembered text
Enjoy
