Well I feel like an idiot, as the commenter below pointed out, the link I mentioned was a bookmark itself, not a “get bookmark plugins” link, but it was showing up in my list of bookmarks, which means that, as the commenter said, this bookmark had been imported from Firefox, and was not actually an indication that Google Chrome was intending to support Firefox Extensions.
The truth of the matter is I was so surprised to find the link, that I didn’t think about logical reasons why that link might have been there. I spun up a fresh copy of Windows on VMWare after the commenter posted, and did an installation of Google Chrome where Firefox had never existed. The link I mentioned below did not exist, which means the commenter was right, it did indeed come from an import of Firefox bookmarks. I’m big enough to admit that I’m wrong.
For archival purposes, my original, incorrect, blog post is after the break. My review of the things I like about Chrome still stands, although my foolish thought that Chrome will support Firefox extensions does not.
