This just checks all a elements (links) and removes target attribute, so they will not open in new tab. target=_blank is extensively used on the Web, but it is very annoying. If user (especially advanced one) want to open something in new tab he/she will do so manually (i.e. using middle click of moue), so this script make life easier and removes all automatic opening in new tabs.
Turn plain text URLs into links. Supports http, https, ftp, email addresses
Many pages have URLs in HTML files as normal text, which is quite irritating when you want to navigate useing it. It mostly consist of selecting text, copying it and pasting into address bar. There are tricks to make it faster but it doesn't really solves the problem: original document isn't hyperlinked correctly.
This userscript searches for all plaintext URLs and changes them to proper links using a href.
It also inteligently handles comma, dot, qustion mark and exlamation mark at the end of URL. Or at least it tries hardly.
