Browser extension CTRL+F for every tab


Hi.
I would like to have an option to search on a webpage
with its own search word.
So I can go to any tab and have its own ctrl+f word search
for that specific tab or window.
(Now its the same word for every search)
Does this extension exist already?
Link please…

If more people is interested in having this option to tab search
please let me know, because if it do not exist
then I want to make this extension to my browser.

Regards from Sweden
