Download Chrome Extension for offline Installation

 Hi folks,

I tried to use my extension for offline usage for a VM based PC browser which doesn't have internet to download the extension.

So, I have come up with this approach where you can download the chrome extension (.crx) file.

Find the extension ID

Sample browser extension URL in chrome web store is below

https://chrome.google.com/webstore/detail/previous-next-page/fmichikmgflpgibapdhepmodjdjemmda

Last word is the extension ID (fmichikmgflpgibapdhepmodjdjemmda)

Download the extension file

Browser: Use Mozilla Firefox or other browser but not chrome

Syntax

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=<<browser_version>>&acceptformat=crx2,crx3&x=id%3D<<extensionID>>%26uc

Example

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=85.0.4183.121&acceptformat=crx2,crx3&x=id%3Dfmichikmgflpgibapdhepmodjdjemmda%26uc

Install the extension

1. Copy the .crx file to your offline computer
2. Open Chrome browser
3. Navigate to chrome://extensions
4. Enable developer mode
5. Drag and drop the .crx file

Hope you will be able to use the offline extensions in chrome.

File Magic Numbers in Header to differentiate between files

Hi everyone,
I just came to know about the file magic numbers
http://en.wikipedia.org/wiki/Magic_number_%28programming%29

Its good that, we can identify the file by converting the file to ASCII even someone changes the file extension manually.

I personally tested this by creating one GIF file and saw the file ASCII values are starting with GIF89a.
Later I manually changed the file extension to JPEG and I verified the ASCII values surprised that still the file ASCII values aren't changed. Its GIF89a.

So, I understand one thing, that, if someone changes the file extension to some unknown type, we can easily find the original file extension by this method.

To see the file ASCII values, use hexdump tool.

See the output ever after changing file extn
