While I am waiting 20 minutes for the “PNAS”:http://www.pnas.org/ site to let me back in, I might as well explain why I have been barred: I use “scrapbook.”:http://amb.vis.ne.jp/mozilla/scrapbook/ It is an extremely useful Firefox extension that grabs whole web pages or portions thereof and saves them offline for later sorting, study, and annotation. It was about 50% of the reason that I gave up on Opera, after ten years — the other big reason was that there are so many Ajaxy sites today that don’t work well with Opera either.
But it turns out that when it hits a site with lots of links, Scrapbook hits them all, too, and so when I went to save “this very interesting”:http://www.pnas.org/cgi/content/full/103/33/12564#related paper on neurogenesis, I triggered their anti-bot. And now I am banned for twenty minutes. Moral: don’t use Scrapbook on that site. Use something like “Evernote”:http://www.evernote.com instead.
But Opera vs Firefox is interesting. I think I will write a piece about standards for next week’s _Guardian_ tech column.
