How to edit xpi (Mozilla Firefox Addon Extension).

Steps to Edit an .XPI (Firefox Add-on) File

1. Extract the .XPI File

• Download the .xpi file.
• Rename it from .xpi to .zip (e.g., addon.xpi → addon.zip).
• Extract the .zip file using WinRAR, 7-Zip, or any unzip tool.

2. Modify the Add-on Files

• Inside the extracted folder, you'll find JavaScript (.js), manifest.json, and HTML/CSS files that define the extension’s functions.
• Edit the JavaScript or other files as needed using Notepad++, VS Code, or any text editor.

3. Repack the Add-on as .XPI

• After making changes, compress the folder back into a ZIP file.
• Rename it from .zip to .xpi (e.g., addon.zip → addon.xpi).

4. Install the Modified Add-on in Firefox

• Open Firefox and type about:debugging in the address bar.
• Click "This Firefox" → "Load Temporary Add-on."
• Select your modified .xpi file to test it.

⚠️ Note: If the extension is signed, you cannot use the modified version unless you disable Firefox’s "Extension Signature Requirement" in about:config.

How to use class="Active" in navigation, If you are using static pages?

My Local Project for Getacho Company

I am working on my own company project. I am using Pixelogic static theme. I created different files for different website parts. like

1. Menu.php
2. Header.php
3. Footer.php

Like it. But here I was facing a problem in class="active" Code. It was like

---

 <nav class="navigation">  
   <ul class="sf-menu" style="float:left;">  
     <li class="active"><a href="index.php">Home</a>  
     </li>  
     <li><a href="about.php">About</a></li>  
     <li><a href="portfolio.php">Portfolio</a>  
     <li><a href="forums/">Forums</a>  
     </li>  
     <li><a href="blog/">Blog</a>  
     </li>  
     <li><a href="contact.php">Contact</a>  
       <ul class="sub-menu main-ul">  
       <li><a href="support/">Support</a></li>  
       <li><a href="support/">Live Chat</a></li>  
       </ul>  
     </li>  
     <li><a href="user/">User Panel</a>  
       <ul class="sub-menu main-ul">  
       <li><a href="user/seo/">SEO Panel</a></li>  
       </ul>  
     </li>  
   </ul>  
 </nav>  

But here I was getting some problem that how to move class="active" according to static current page.
Then I consulted with my friends and someone suggested me a code. now it is working.

Code was :

---

 <?php  
      $url = $_SERVER['REQUEST_URI'];  
      if (strpos($url,'about.php') !== false)  
           echo 'class="active"';  
 ?>  

Here you need to understand STRPOS function.
I used same code in my navigation. Now navigation is working good. Now navigation code is

---

 <div id="menu" class="clearfix">  
   <nav class="navigation">  
     <ul class="sf-menu" style="float:left;">  
       <li   
       <?php   
       $url = $_SERVER['REQUEST_URI'];  
       if (strpos($url,'index.php') !== false)  
       {  
       echo 'class="active"';  
       }  
       ?>  
       ><a href="index.php">Home</a>  
       </li>  
       <li   
       <?php   
       $url = $_SERVER['REQUEST_URI'];  
       if (strpos($url,'about.php') !== false)  
       {  
       echo 'class="active"';  
       }  
       ?>  
       ><a href="about.php">About</a></li>  
       <li   
       <?php   
       $url = $_SERVER['REQUEST_URI'];  
       if (strpos($url,'portfolio.php') !== false)  
       {  
       echo 'class="active"';  
       }  
       ?>  
       ><a href="portfolio.php">Portfolio</a>  
       <li><a href="forums/">Forums</a>  
       </li>  
       <li><a href="blog/">Blog</a>  
       </li>  
       <li   
       <?php   
       $url = $_SERVER['REQUEST_URI'];  
       if (strpos($url,'contact.php') !== false)  
       {  
       echo 'class="active"';  
       }  
       ?>  
       ><a href="contact.php">Contact</a>  
         <ul class="sub-menu main-ul">  
         <li><a href="support/">Support</a></li>  
         <li><a href="support/">Live Chat</a></li>  
         </ul>  
       </li>  
       <li><a href="user/">User Panel</a>  
         <ul class="sub-menu main-ul">  
         <li><a href="user/seo/">SEO Panel</a></li>  
         </ul>  
       </li>  
     </ul>  
   </nav>  
 </div>

How to create Database with SQL Query?
> Open  PHPMyAdmin > SQL

 CREATE DATABASE QWC  

Write Query and click GO. Now QWC database has been created.

 Query OK, 1 row affected (0.01 sec)  

Now  You need to use this database. Use this SQL query.

 USE QWC;  

Write Query and click GO. Now you are using QWC database.

Database changed

 Now you need to create tables. For tables, you need to write query as

 CREATE TABLE inform(  
 name varchar( 30 ) ,  
 age int( 2 ) ,  
 phone int( 15 ) ,  
 address varchar( 50 )  
 )  

It is like

Create Table [Table Name]( [Field Name] [Field Type] ([Field Limit]) , [-> Next Field] );

Write Query and click GO.

Query OK, 0 rows affected (0.01 sec)

Now You need to insert value. 1st you need to check that your table is selected. For value, you need to use this query as.

 INSERT INTO `inform`(`name`, `age`, `phone`, `address`)   
 VALUES ('QWC',22,03234209211,'Pakistan')  

It is like

Insert into table (colum1, colum2, colum3) values (value1, valu2, value3, value4);

But here you need to remind that you need to write CHR, Text type values within single or double quotes.
