Clear Cache and Cookies shortcut for Firefox, Internet Explorer and Chrome Browsers

This is how you clear your cache and cookies on all major browsers without navigating through the entire menu and options to find the caching section.

Typically on most Firefox versions the caching & cookies section is under:

Firefox Menu > Options > Options > Privacy Tab > clear your recent history (link) but that’s too many clicks.

In Chrome:

Customize and Control Google Chrome button > Tools > Clear Browsing data.

In Internet Explorer:

Tools > Internet Options > General tab > Browsing history section > Delete

So, here’s the only Windows keyboard shortcut you need: CTRL+SHIFT+DELETE – this brings up the Clear All History window on all browsers.

If you’re running Windows on a mac pc, then the shortcut would be: CTRL+SHIFT+FN+DELETE – same result as above.

The CTRL+SHIFT+DELETE shortcut works on all versions of Firefox, perhaps most Internet Explorers and Google Chrome.

Samsung Galaxy S3 (I9300) one click ROOT with ExynosAbuse Android APK

ExynosAbuse is an android application that uses an exploit to gain root privileges and install SuperSU (v0.99) on your Samsung Galaxy S3 – Exynos4 chip based device.

It doesn’t require anything else, and it will grant the user full root privileges without asking and without using any special permissions.

Even though, this is not something you should take lightly (as the hack could be used by third-party apps with malicious purposes), it is the fastest, simplest way to date, to get root access on a Samsung Exynos4 type device running factory stock roms. (Finally a simple method of using Titanium Backup without flashing custom images, bootloaders, unlocking device, etc.)

ExynosAbuse App ScreenShot

The current version of the app is 1.20 and starting with version1.10, it has the options to disable the exploit (disclaimer: this may break your camera), re-enable the exploit (if you need the camera) and to disable the exploit at boot (before any Android app runs). These options do require root (SuperSU or Superuser) to be installed as well. While this will help protect you, these are workarounds, not actual fixes.

All you need to do is download the app from the links provided below (or the original forum threads), install it (make sure you have enabled “installing from unknown sources”), and click the “Root device” button.

Samsung has been informed of this vulnerability, and it is likely that a fix will be available in the near future, but until then, if you were looking for a 1 click ROOT your Galaxy S3 procedure, this is it.

The method has been tested and works on the following devices (check the forum thread below, as it will be updated with new devices):

  • Samsung Galaxy S2 GT-I9100
  • Samsung Galaxy S3 GT-I9300
  • Samsung Galaxy S3 LTE GT-I9305
  • Samsung Galaxy Note GT-N7000
  • Samsung Galaxy Note 2 GT-N7100
  • Samsung Galaxy Note 2 LTE GT-N7105
  • AT&T Galaxy Note 2 SGH-I317
  • Verizon Galaxy Note 2 SCH-I605
  • Samsung Galaxy Tab Plus GT-P6210
  • Samsung Galaxy Note 10.1 GT-N8000, GT-N8010, GT-N8013, GT-N8020


  • to check that your device has a Exynos4 CPU, use Antutu Benchmark android app and go to the Info Tab > Device Info and look under Basic Information.
  • take into account, that rooting the phone may also void your warranty, so use carefully.
