Change Address Bar Search Provider In Firefox

Firefox logo

Address bar search is the feature that allows you to search for a keyword entered in the address bar (location bar) without entering the search engine homepage. Firefox by default will look for the keyword entered in the address bar in Google search as it is usually set as the default search engine to manage address bar keywords.

However, you might want to change it to suit your personal interest. It may sometimes can also be a case of hijacking: You install some programs that they change your search bar address bar search provider without asking for your permission (ex: so many toolbars like Alexa, Yahoo etc.). For some reasons, if you want to change the Firefox address bar search provider, you can do it by following the steps below:

1. Type about:config in the Firefox address bar. You will be presented with a warning, if you are using Firefox 3.5 + version, just click “I’ll be careful, I promise”!” to continue to the about:config page.

Firefox_about_config_warning

2. In the Filter search box, type “keyword.url” and the result returns only one result as shown in the screenshot below.

keyword.url_firefox

And as you can see here, the address bar search engine provider in my case has been changed to Alexa, when I installed it’s toolbar sometime back. Now I want to change it to a different provider, back to Google may be, or Bing? Well I can even test how it works with Twitter search.

3. Right-Click on the field value and click “Modify”.

change_firefox_keyword.url_string_1

You will now be asked to enter a string value for the keyword.URL, choose the values according to the provider, as listed in the table below.

change_firefox_keyword.url_string

List of  string values of various search engines:

Google http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q=
Yahoo http://search.yahoo.com/search?p=
Bing http://www.bing.com/search?q=
Ask http://www.ask.com/web?q=

Click OK to save the settings and checkout the result yourself with typing a keyword in the address bar of the Firefox.

[How To] Make Gmail More Secure By Using HTTPS Instead Of HTTP

“If you sign in to Gmail via a non-secure Internet connection, like a public wireless or non-encrypted network, your Google account may be more vulnerable to hijacking. Non-secure networks make it easier for someone to impersonate you and gain full access to your Google account, including any sensitive data it may contain like bank statements or online log-in credentials” – Google

In order to avoid such kind of security risks we should enable HTTPS(Hypertext Transfer Protocol Secure) which is a secure protocol that provides authenticated and encrypted communication and the interceptors will not be able to tap the information.

You might have seen HTTPS being used in the banking and payment websites. So by using HTTPS for your Gmail, you will be able to a secure you mailbox.

In order of enable HTTPS protocol follow the steps below:

1. Sign in to Gmail

3. Check If your Gmail is secure?

Check if you have a https://mail.google.com url. If not then follow the steps else not required as it is already enabled.

gmail_url

3. Click Settings at the top of any Gmail page.

gmail_settings

4. Set Browser Connection to Always use https

always_use_https

5. Click Save Changes.

save_gmail_settings

6. Log out and Login.

7. Now find a secure login

You can see https://mail.google.com in the url.

gmail_https_url

Now you Gmail is as safe as you internet banking site. But never forget to Logout your account if you are using a public computer.

Notes:

  1. Using HTTPS may slow down a bit the speed of accessing your Gmail, so if you trust the security of your network, you can turn this feature off at any time
  2. “Always use https” will prevent you from accessing Gmail via HTTP
  3. Currently Gmail has enabled HTTPS by default. For the old users you can follow the method.

[How To] Stop or Disable Hotlinking and Bandhwidth Theft using .htaccess file

We found out that many of our copyrighted popular posts have been copied by many of the bloggers. But with so many traffic hungry bloggers around, it is impossible to track and warn each of the bloggers.

Now, our main concern is that many of our copyrighted images are not only copied to other blogs but also hotlinked. This is a serious issue with every popular blog where hotlinking results to bandwidth theft. Now if you are having similar problems of hotlinking or not, you should disable hot linking for sure.

What is Hotlinking or Inline linking?

Inline linking (also known as hotlinking, leeching, piggy-backing, direct linking, offsite image grabs) is the use of a linked object, often an image, from one site into a web page belonging to a second site. The second site is said to have an inline link to the site where the object is located.[wikipedia]

This is when you insert an image to your blog from an image URL of someone else’s site instead of uploading the image to your server. Many people with limited server storage size tend to do this.

How to stop Hotlinking and Bandwidth theft using .htaccess file?

In order to disable hotlinking follow the steps below:

1. Open your .htaccess file by saving it.

.htaccess file is present in the public_html folder of your blog. This can be accessed by using the ftp client like FileZilla. Hope all webmasters know this. Save the file and open it using notepad.

dot_htaccess

2. Add the code to disable hotlinking of your images

Add the following code to your .htaccess file and save it back to your public_html folder.

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+\\.)?yoursite\\.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*\\.(jpe?g|gif|bmp|png)$ http://imagehostsite/warning.jpeg [L]

Change the orange colored code according to your need as shown in the example below.

Example: [Click to Enlarge]

disable_hotlinking

The RewriteCond can be added according to your purpose. If you have any other blog where you want to use the images, then add another line with the site’s address as we have done in the example.

Important notes:

1. Backup your .htaccess file before doing the changes.

2. in the RewriteRule line, you cannot use a warning image uploaded to your site because the warning image itself will be blocked. So upload the image to some other servers like blogger or other image hosting sites

3. The RewriteCond can be added according to your purpose. If you have any other blog where you want to use the images, then add another line with the site’s address.

Now after performing the changes, you can check the other site where your images are hotlinked. An example is given below where our most popular post Reset Windows XP, Vista, 7 Password Using USB Drive or CD was copied.

Hope you have seen something like ours. Any feedback will be appreciated.

How To Report About Third-Party Adsense Ads Distributing Malware

Google Adsense Logo

Earlier this year, Google has made Google-Certified ad networks available to all publisher by default.It is intended to benefit the users who can now attract additional advertisers from third party ad networks to their site through Adsense.This was really an impressive move by Google to benefit its Adsense publishers.

But off late, we have been hearing various complaints about the ads from these third party networks circulating malicious code through Adsense.

For example, quite a number of Adsense publishers with a good anti-virus program installed on their system have figured out that the following virus alerts protruding from their program whenever they open the page containing that particular ad:

http://curves.com/?=345 contains a trojan

Are you one of those publishers experiencing the problem? have no clue about how this is happening ?

Google-certified ad networks who want to place ads in Adsense publisher sites must adhere to all AdWords policies in general.But in this case, the particular ad network which was already certified by Google, started spreading malware later on and as a result some Adsense publishers who were displaying ads from these third party ad networks have been recieving the reports of attacks on their website readers computers through Adsense code.Google however has revoked that particular network’s certification.

We recently learned of a malware-infected creative that came from Aggregate Knowledge, a third-party ad network that was certified by Google at the time. As a result, we revoked that network’s certification, and their ads are no longer eligible to appear on any AdSense publisher sites.

How To Report If You Face Similar Problem?

You need to report through AdWords ads feedback to report about  ill behaviour of a particular ad network from this page.

You need to note the URL of the webpage that this particular ad takes you to when clicked (Warning: Don’t never click on your own ads, instead ask your readers who had faced the problem to pass on the URL to where they were being taken by the ad).Also you need a screenshot of the ad to submit to the AdWords team for analysis.

The report from would look like this one:
