Its much like having the phone conversation with a friend and panicking that you cant find your phone.
Silly, but if you download/speak on your phone often enough, these things tend to happen.
The latter is unfortunately something that no web client addon can prevent.
The former, however, is very easily managed.
To get the addon, just follow the link at the bottom of this page and follow the prompts.
Dont forget, youll need to restart Firefox before it will be enabled.
In action, the large version looks something like this, depending on whether youve customized it.
To switch to mini mode instead, clicking the Downloads button, then options.
Then just smack the little Mini Mode box.
And everything gets quite a bit smaller, even with several downloads displayed.
Theyre only shown when you click, by the way.
The advantage here is that Full Mode allows for a little more information if you hover over your downloads.
One feature to note is the ability to automatically scan downloaded files for viruses using your allocated virus scanner.
Just click Options, head to the Virus Scan tab, and choose your Anti-Virus program.
And thats the gist of the program.
No real pretty pictures or anything, just bare bones functionalism.
