I began using this after the original YesScript was no longer supported with the updated version of Firefox. I have but one complaint with YesScrpt2 which is I really miss a little feature YesScript had, which was the ability to block scripts prior to opening a website, and then immediately unblocking them so that link subsequently clicked on aren't blocked without reloading the page.
This would allow me to enjoy a webpage with a lot of content on it and not get blasted with scripted nonsense and have to deal with the page reloading on me every 30 seconds; however, I when I clicked on a link on the website I was able to load that one link with full scripts.
This little process/feature was super-nice for websites with a bloated front page designed for long term browsing, such as news sites, for example, but they also load it with a bunch of garbage and have the page annoyingly set to reload on you every 30 secs.
When I tried this little trick with YesScript2, it now reloads the page every time I stop blocking scripts rather than just leaving the current page loaded and blocked and then unblocking subsequent clicked-links.
