How’d I Get Here (high)? is a Firefox extension that allows you to go to the page on which you first clicked a link to the current page. say, for example, you want to go « back » even after opening a link in a new tab and closing the original tab, or you want to remember how you found a site you bookmarked yesterday, or better if you are sent a link you have already seen, you can astound the sender by responding with a statement more precise than « I saw that on some blog a few days ago ».

Send Referer is a ff extension which allows you to browse the web as usual, except that your browser won’t send referer header. When you come across a link you can’t follow without referer, right click on it and use « Open Link with Referer Header ». Sending Referer Header will be enable for 7 seconds and then it will go back to no referer mode.
