gBrain is a Firefox extension to automagically bookmark all pages you visit at the Google bookmark service. This effectively moves your browser history from your browser instance to a central place on the net (Google) where it is easily searchable from every computer.

1. Install the gbrain-0.5.4-fx.xpi file
2. Restart Firefox
3. Rightclick your Firefox toolbar and choose “Customize…”
4. Drag the gBrain Icon into your toolbar
5. Add your Google account data in the config dialog (access through extension manager or right click the gBrain icon)
6. Surf on…

Usage should be self explanatory. Each site which is visited will be bookmarked at Google Bookmarks tagged with !gbrain and three tags representing the current year, month and date.

In addition to the predefined tags you may add your own tags that should be added automatically in the config dialog. This may be useful eg. for assigning different tags for sites visited from work and those visited from the browser at home.

To avoid bookmarking pages without any use you can configure an exception list in the config dialog. You need to enter regular expressions that should match the unwanted sites. gBrain comes with a few handy preconfigured ones. New regexps based on the current page URL can be quickly added through the toolbar button's context menu.

The toolbar button features multiple functions:

1. left click it to quickly enable/disable the extension (the icon turns gray when disabled
2. middle click it to open your Google Bookmarks in a new tab
3. right click it to open the context menu
