Find and Replace Chrome Plugin Works But Reverts Back to Original

As many others I need to paste over 100 times to put the project name ahead of all task names.
I saw another poster had a work around to use the Chrome Find and Replace add-on.
It works however immediately reverts back.
Can someone make the system hold the replacements if you will not make a find and replace feature (which I see many, many people also requesting for years with no traction)?
