hello

is there a tool that will monitor all the webpages I
visit and it will save specific text/links/files?the problem is that most of
similar programs (web
spiders, etc) require you to enter a starting web
address, then specify retrieval options and then let
the program do the job
I want an integrated solution to do this within my
browser "as I browse"
opera, for example, has this javascript function:
document.addEventListener('DOMContentLoaded',function()
{
where it does things when the webpages are loaded
thanks
