How to change the default search engine in Microsoft Edge web browser from Bing to Google or others

Microsoft Edge is the web browser that comes together with MS Windows 10, which is made to replace Internet Explorer.

By default, it will use Bing as its search engine to search for the keywords you typed in its search bar. If you want to change the search engine to Google, Yahoo, Baidu or others, follow the steps below.

First, you need to use Microsoft Edge to visit to the webpage of your preferred search engine, eg. http://www.google.com.

Then, go to the Settings panel.


Scroll down to Advanced Settings section, and click on the "View advanced settings" button.


Scroll down to "Search the address bar with", and select "".

You should now be able to see "www.google.com". Select it and click the "Add as default" button.


You can repeat the steps above to add in more search engines to the selection list.


How to mitigate excessive Internet data usage of MS Windows 10

If you have upgraded your Microsoft Windows operating system to the latest Windows 10, and found out that your computer is taking up a lot of your Internet bandwidth and consuming a lot of your data usage, there are 2 settings for you to mitigate this problem.

The first setting is to disable peer-to-peer sharing of Windows Update files and Windows apps that you have downloaded in your computer with other MS Windows 10 computers in the Internet.

Go to Start > Settings > Update & Security.


Then, go to Windows Update and click on "Advanced options".


Inside Advanced Options, click on "Choose how updates are delivered".


In the next screen about Update from more than one place, you can either set the option "when this is turned on, your PC may also send parts of previously downloaded Windows updates and apps to PCs on your local network, or PCs on the Internet, depending on what's selected below.' to OFF, or if you want to share with PCs within your local network but not across the Internet, leave it as ON and select "PCs on my local network".


If you leave the option to be the default "PCs on my local network, and PCs on the Internet", many computers from the Internet will just swarm in and suck off your Internet bandwidth, causing your computer and your Internet link to become slow, and if your Internet line is on quota usage, this will also consume up your data plan within a short period of time.

To further mitigate the Internet data usage, the second setting is to tell Windows that your Internet connection is metered connection. This will prevent background processes and Windows apps use up your Internet link to sync information and provide real time updates to you.

Go to Start > Settings > Network & Internet.

Then click on "Advanced options" under Wi-Fi screen.

Set the Metered Connection to ON.

If your Mozilla Firefox web browser can no longer access certain HTTPS websites, try this fix

Mozilla Firefox version 39 onwards will by default block the HTTPS connections to web servers using weak ephemeral Diffie-Hellman (DH) keys.

Bear in mind that by default, Firefox is set to automatically update itself from time to time, so your version will eventually be updated to version 39 and above.
This is a security measure against the Logjam attack. You can click here to read more about this Logjam attack.
If you visit to an affected website using HTTPS connection with Firefox, you will see the following error message:

Affected websites including the webmail of older version of Zimbra Collaboration Suite. Click here for more detail.
You can fix this by installing the Disable DHE 0.1.2 Add-on by Mozilla to Firefox.

To install, go to Menu > Add-ons in Firefox, and search for "Disable DHE". Once you found the add-on, click the Install button to install it.

Restart Firefox and check if this fix works for you.
