Zoom In and Zoom out with Web Browser

I recently talked to a friend who very pissed off with the font size of a website. He was surprised when I showed him that the web browsers (whether is Firefox, Internet Explorer or Google Chrome) in fact already have the build-in feature to allow you to zoom-in and zoom-out from a web page. I'm not sure about Safari but I suspect it should have a similar feature.


How to Zoom In and Zoom Out?

• Zoom-In: Press and Hold "Ctrl" & "+" button or Press "Ctrl" & move "Mouse wheel Up"
• Zoom-Out: Press and Hold "Ctrl" & "-" button or Press "Ctrl" & move "Mouse wheel Down" 

To reset to original default zoom, you need to press and hold "Ctrl" & "0".  All these work for Firefox, IE and Google Chrome except for "Ctrl" & "+" in Google Chrome. It somehow doesn't work in Google Chrome. Perhaps this is the bug in Google Chrome?

Hope this helps. It used to require to install plug-in to use this feature and now no longer needed anymore. :)

Enable HTTP Pipelining to Increase Firefox Speed

If your Firefox browser is too slow especially when you open many tabs at one time, you can consider to enable the HTTP pipelining feature in the browser. By default, this feature is turned off and you have to manually tweak the browser configuration to enable it.

Steps to Enable HTTP Pipelining:

• Enter “about:config” at the address bar and press enter. You will see the following screen. So click “I'll be care, I promise”.

• In the filter box, type “pipelining” and you will see the following screen.

• Double-click the “network.http.pipelining”, it will be changed from the default “false” to “true”. Double-click again will change back to “false”. Since you want to enable the “http pipelining”, you make sure the value is “true”.

• Double-click the “network.http.pipelining.maxrequests” and change the default value 4 to 8 .

• Click OK and close the page.

The supported maximum value for pipelining request in firefox is 8 - change 10 to 8.

Note: Why 8? It is up to you to set the value. If the value is too high, it probably will hurts more and cause more delays. 10 is just a recommended value that I play around with and it seems pretty cool. Of course, you can play around with your own number to optimize your browser's speed.

In short, HTTP pipeling is a HTTP protocol that does not required the client to wait for the server to respond and keep sending the request. Because there are some delays waiting the respond from the server, enabling this HTTP feature can actually speed up the browser's page loading speed.
