Disable Open URL on Middle Mouse Click in Firefox 3 Beta

I recently began using the Firefox 3 Beta 4. Overall, I am very impressed by it's performance, but I encountered a new feature that I wasn't crazy about. When I use Firefox, I always click links with my scroll wheel in order to open them in a new tab. Firefox 3 has a nifty new feature that when you click the scroll wheel while not hovering on a link, it will try to load your clipboard contents into the browser as a new URL. Problems arise when you don't have a valid URL on your clipboard and the Firefox just throws an error:



Needless to say, for someone who clicks the scroll wheel a lot, the presence of this error message gets tiresome rather quickly. Luckily for me, disabling this option is very simple, though it requires some playing around with Firefox's internal settings.

1. Open the Firefox browser and direct the browser to: about:config
2. Firefox 3 will display a warning about changing your configuration. Tell Firefox you know what you're doing by pressing the button labeled 'I'll be careful, I promise.' This will bring you to the Firefox configuration screen.
3. At the configuration screen, there is a huge list of tweakable settings. The one we're looking for is 'middlemouse.contentLoadURL' - The easiest way to get to this value is to use the 'Filter' search at the top of the configuration page. Just type in something like 'middleMouse' and you'll see the configuration page filter out the other results.
4. Once you locate 'middlemouse.contentLoadURL' you'll want to double-click that line, which will cause the line to go bold and will change the 'value' to False.
5. You're done. I told you it was easy.

As I said, Firefox 3 is great. It's definitely ready for prime time, from the use I've gotten out of it so far. It seems to run a lot smoother than FF2, and uses much less memory. If you're interested in trying it out, check out Mozilla's download page here.

Ubuntu shows that iPod (or any mass storage device) is full when it's not.

In Ubuntu, I have noticed that sometimes when mass storage devices (particularly my iPod) will sometimes be recognized as having no free space when I know, in fact, that there are several gigabytes worth of free space. I had searched for a couple hours until I finally discovered a way to fix the free space on device.

To fix:

1. Plug in the device.

2. Open a Terminal and type:

you@linux-box:~$ df -h

3. Look for your iPod's name in the list of disks. It should be something like /dev/sdf2 or something similiar. Look to the right hand column for the name of the media. Take note of the directory in the left column (/dev/sd**)

4. In the terminal, enter the command:

you@linux-box:~$ sudo dosfsck -rV /dev/sdf2

but don't forget to replace /dev/sdf2 with the path to your device.

5. dosfsck will begin checking the drive for inconsistencies, and prompt you with a message about 'Free Cluster Summary Wrong'

6. When it asks you

1) Correct
2) Incorrect
?

you want to type '1' and hit enter.

7. After this, it will start verifying your device and will ask you if you want to Perform Changes. Type 'y' and hit enter and it will make the changes on your device.

8. Then, in the terminal, type:

you@linux-box:~$ sudo eject /dev/sdf2

Again, making sure that you replace /dev/sdf2 with the path to your device.

9. Your device will unmount. Unplug your device and plug it back in and your device should display the correct amount of free space.

This has yet to fail me and I've used it a number of times. Good Luck


EDIT:

Overall, your session should look like this:
