How to completely clear url history on firefox

Recently I came across a  question regarding how to Clear Completely the suggestion provided by browser which generally comes from our Browser History.

Truth is, Suggestions comes from two sources:
  1. Browsing History
  2. Bookmark Favourites
How to get rid of them?

Solution 1: Private Browsing

Private Browsing allows you to browse the Internet without saving any information about which sites and pages you’ve visited.
How to use it:

Tools -> Start Private Browsing

Click on Start private browsing button when asked 
(you may/ may not check the check box there)


Solution 2: Browsing History

 Tools -> Options

In History section

Choose Never remember history

In Location bar section:

choose Nothing

   With above, also check your Bookmarks/ Favorite/ Starred links. Remove unwanted address from there.

Happy Browsing.. :)

How to fix Registry editing has been disabled by Your administrator

You try to run regedit form start menu you are getting an error like this 'Registry editing has been disabled by administrator'

 Regedit is widely used to successfully remove Virus and their effects. This is also the reason why virus makers love to disable the Registry Editor so it makes solving the problem and removing the issue difficult.

Viruses are not always the reason for this issue sometimes administrators in IT departments place a restrictions on using the regedit command to keep employees from changes things on company computers.

 Let us look at the solution to fix it:

 Solution 1: Using the Group Policy Editor

  • Start -> Run -> gpedit.msc and press ENTER
  • Expand the '+' sign to go to the following location: User Configuration ->Administrative Templates -> System
  • Double-click 'Prevent access to registry editing tools' and set it to Not Configured
  • Exit the Group Policy Editor
    If the setting already reads Not Configured, set it to Enabled, and click Apply. Then revert it back to Not Configured. This ensures that the DisableRegistryTools registry value is removed successfully.


Solution 2: Using the REG.EXE console tool  

Start -> Run -> type this command:

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

Solution 3:
Symantec has developed a tool UnHookexec.inf which makes access to registry editing easy and sets their registry values to their default values. It is an inf file right click the tool and install . 

Solution 4:

Download this VB script file from doug Knox Website and run it .If you get any warning click ok to continue. After VB Script file enables registry editor ,restart your computer and access registry.

Solution 5:

Some viruses and other malware will load a regedit.com file that is many times a zero byte dummy file. Because .com files have preference over .exe files when executed if you type REGEDIT in the run line, it will run the regedit.com instead of the real regedit.exe file.

Delete the regedit.com file if its a zero byte file to restore access to REGEDIT. In some cases, such as the W32.Navidad worm, you'll need to rename the REGEDIT file to get it to work.

 Happy Troubleshooting ...

How to Restore " Show Hidden Files and Folders " or " Folder Options "

When your system is infected with virus,first one to be get affected is "Show Hidden Files and Folders"(in Win 7 / Vista) or "Folder options" (in Windows XP). 
Folder options entry will not  appear in Windows Explorer to see hidden files and folders. Hence Virus can safely hide itself in your system

In Win7/ Vista

 "Folder and search option" will look like: 

computer has no option for “Show Hidden Files and Folders” in the Folder Options dialog.

 In Windows XP

 "Folder options"(shown in fig.) will not be available in the Windows Explorer Tools menu.


 For Win 7/ Vista

Open regedit.exe through the start menu search or run box, then navigate down to the following key. 


 On the right-hand side, Look for a key "Type" and change its value to "group"as shown above. 
If the key does not exist, create a new String value.

You should be able to immediately re-open the folder properties, and the option should have returned, as you can see here:

For Window XP

Start menu->Run-> Type "regedit.exe" ->Enter 
Registry editor will open, then navigate down to the following key:


On the right panel, Look for a value called "NoFolderOptions"

Right click on the NoFolderOptions value and choose delete
