If you are Google's fans, I think this should be installed. It integrates Google's reader, mail, notebook, calendar, photos, and document into a toolbar. You only need to click the corresponding icon to display the information of the entry, instead of switching back and forth between apps.
Firefox installation extension addressIgooglebar
I have just installed this item, but I have not found it on the Firefox toolbar for a long time. Is itProgramError. Later I found out that it was like this:
Igooglebar Not Installed
Install igooglebar
The icon is added before the original word. Click the image to display a widgets, showing the specific content. It is convenient and practical. This tool operates the googlereader Dom.
But I found that this extension is only useful in Doc, reaer, and photos, and I don't know how others are doing.
