The way Mozilla Firefox and i2Brain work together is described here.

Drag and drop

Many programs use "drag and drop". "Drag and drop" is the technique whereby you "drag" an item of data (text, a graphic or a list of files etc.) onto another program (while the mouse-key is pressed) and "drop" it there.

You can also drop data onto i2Brain. Try this: mark and drag any old text from an editor or your browser and drop it onto an empty area of a whiteboard in i2Brain. (You can tell that your editor understands "dragging" because the cursor changes shape as soon as you start dragging the previously marked text.) And you can see that i2Brain is prepared to accept a drop with the current information because the mouse retains its special appearance.

Dropping a file (from Explorer or another list of files) also creates a new item. The item's name is the file's name (including its path). If the current project has an aspect defined to "call external programs" (which is usually called "URL"), then the path and name of the file are inserted into that aspect. Thus the new item is a bookmark to the file.

The same is true if you drop a graphic onto i2Brain, except that the aspect where "shows a graphic" is activated is filled with the path and file-name.

Mozilla Firefox and the Internet Explorer have an icon which you can drag. It's to the left of the address.

Dropping onto an item

You see a similar behaviour when you drop a text, the name of a graphic or a URL onto an existing item: the item receives the data as described above, but no new item is created.
