I couldn't find a Chrome plugin for QS. An obvious workaround is to use something like xmarks to sync bookmarks with Firefox or Safari. But this won't get you access to Chrome's history.
I'm not up for writing a plugin. But I have managed to hack together access to both the bookmarks and the history. The fact that this was easy to do makes me suspect that writing a plugin would not be too difficult for someone who has the time and knows how to write QS plugins. 1. Bookmarks Chrome stores its bookmarks in a JSON formatted file. There is a python script that converts this to html here: http://www.capybara.org/~dfraser/archives/355/comment-page-1#comment-9932 The script will generate an HTML file. You can set the name and location of that HTML file by editing the value of the output_file variable in the script. QS can scan that file for links (Catalog-- >Custom-->+ File and Folder Scanner-->Source Options-->Include Contents-->HTML Links). 2. History Chrome stores its history in an SQLite file. I have no sqlite foo. But AlecSashka provides a command line that will dump the urls into a txt file here: http://www.google.com/support/forum/p/Chrome/thread?tid=0dd0b74a4e45a6a7&hl=en Based on this, I've thrown together a fairly trivial script that will generate a txt file with one url per line: https://gist.github.com/864823 QS can scan this file for links (Catalog-->Custom-->+ File and Folder Scanner-->Source Options-->Include Contents-->Text Lines). You'll need to run these scripts every time you want to refresh QS's catalog of Chrome's history and bookmarks. You could make this automatic by using cron or launchctl. I haven't bothered to do that. -David
