How to Speed Up Mozilla Firefox

SlowFirefox-Itis. n. The thing that happens to Firefox over time. Symptoms include decline in speed and efficiency.
So, you’ve turned on your computer, clicked on Mozilla Firefox, and then….you waited. “Why,” you say, “Is firefox slower now?”
Well, we’re here to fix that problem! Whether it’s just because you want to make Firefox faster than it already is (which is wickedly fast anyway), or because you want to fix your declining speed, you’ve come to the right place.
Please note that if you do not have firefox as your default browser, I advise you to get it immediately. It is faster and more efficient than every browser out there. It is obtainable at mozilla.org/firefox.
If you use all the methods put together, you should be able to see a speed increase of at least 50% on Firefox.
Method 1:
Okay, well. To begin with, I will tell you how to increase your bandwidth speed by 20%.
Windows actually reserves 20% of your bandwidth for purposes I will never know. I’ll show you in a few easy steps, how to reclaim it.
Step 1:
Click “Start“, and go on “Run“, and type in “gpedit.msc“. You should see this:
gpeditmsc
Step 2: You should see a thing called ‘Group Policy’ open.
Step 3: Double-Click on “Computer Configuration”.
Step 4: Double-Click on “Administrative Templates”
Step 5: Double-Click on “Network”
Step 6: Double-Click on “QOS Packet Scheduler”
Step 7: Double-Click on “Limit Reservable Bandwidth”
Step 8: Check the box that says ‘Enabled’ and change Bandwidth Limit (%) to 0.
You got 20% increase on your bandwidth speed! Easy, was it not?
Method 2:
The next way is to modify the amount of requests can accept at once. By changing it to a very high number (30+), you should see a massive rise in speed.
So, to this, I’ll put it in a few easy to follow steps.
Step 1: Load up Mozilla Firefox. Now, in the address bar, type “about:config” (Without the ” ” of course). You should see this:
aboutconfig-addressbar
Step 2: Scroll down the page until you find browser.tabs.showSingleWindowModePrefs, and then double-click it. This will set it to “True”.
Step 3: Next, scroll down look for the line that says network.http.pipelining, and double-click this. This will set this to “True”.
Step 4: Now, scroll down and look for network.http.pipelining.maxrequests. Once you have done this, double-click it, and a box will pop up. Change the number to 60.
Close Firefox. You will now experience a 10% to 40% increase in speed.
Method 3:
Finally, the last way to increase your speed, is by using an add-on for Firefox, called FasterFox. It’s increased my speed greatly. Although, my friend, who owns a weak computer, said it doesn’t work well for him, so if your computer is weak, you may want to stop here.
FasterFox basically increases your speed by recycling all the idle bandwidth not doing anything, and makes it load your pages faster.
fasterfox2
You can get FasterFox at http://fasterfox.mozdev.org/.
Install it, and your done! Hopefully, you now have a faster running Firefox! Any other ideas, post a comment!

Protect data from copying data from usb....

USB ProtectedFor those of you who want to protect the data on your computer from the action of copying, I think need to limit your computer so that users can not write, copy or move data in flash disk.
  1. Open the Registry Editor (Start Menu> Run, type: Regedit, and press enter / click OK)
  2. Look for the following Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
  3. Create a new key (right click and choose New> Key), then give the name StorageDevicePolicies
  4. Then open StorageDevicePolicies and right click select New> DWORD, Value named WriteProtect
  5. Double click the WriteProtect, on the value, fill with value 1. Click OK
  6. CurrentControlSet addition, alteration must also be done in key ControlSet001, ControlSet002, and so on if any. So be on the check in the following Key :
    • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolicies
    • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\StorageDevicePolicies
    • ...
After the set as above, then all users who use the computer can not save, copy or move data to a USB Flash Disk.

Secret Tip How I Make Free Calls from Computer to Mobile Phone Anywhere in the world with yahoo messenger or Skype

Make Free Calls from Computer to Mobile phone
You can now make free calls from your pc to any mobile in the world. All you need is a mic with ear phones, a decent internet connection and Yahoo Messenger or Skype Installed.I’m now using this free call method and the great thing is that, this trick can be used to make unlimited call to mobiles all over the world and not limited to United states. It even works to make free local mobile calls in India.

So how do we make a call from pc to mobile phone for free?
Install Yahoo messenger or Skype. In case you don’t have it Google it and download the latest version.
Sign into your yahoo messenger or Skype using your yahoo id and password. Configure your microphone and headset if you have installed a fresh yahoo or skype software
Inside your Yahoo messenger dial +18003733411 and press enter(as shown in figure).
Make Free Call from computer to mobile using Yahoo messenger or Skype
Now a small window pops up like the one shown below.
Free Call from Computer To mobile using Yahoo Messenger
An operator greets you with a recorded welcome message along with an advertisement and asks you to select one of the Free411 service. Just hear the services options until they say the last one as “Free Call”. When you hear this, don’t press any number on your keyboard and instead SAY “Free call” loudly on your microphone connected to your PC.
After this voice message is detected by their system, they will run a short advertisement of their sponsor and make sure you don’t press any number at this time.
WAIT UNTIL YOU HEAR A BEEP SOUND after the following message “Please dial the phone number country code first, don’t forget to dial 1 for north America”
After you hear this message ,immediately dial the destination number of your choice along with the country code.(e.g. for north America it’s 1 and for India it’s 91)
Your call will get connected and you can talk for 7 minutes continuous for free. When it gets disconnected, repeat the same procedure again. You can make multiple and unlimited calls with this service.
It was never easy to make a free international call like this before.
So what’s the catch?
FREE411 service toll-free number is based in USA. This company gets paid for the advertisements from sponsors.
Are there any limits on the number of call which we can make?
No. There is no limit on the number of free calls which can be made through this system.
So enjoy this trick to make free international and local calls and make sure you don’t abuse the system.
