HOW TO INSTALL A ZIPPED BROWSER EXTENSION
==========================================

STEP 1: UNZIP THE FILE
----------------------
Before doing anything in your browser, you must "unzip" the folder:
1. Right-click the .zip file and select "Extract All" (Windows) or 
   double-click it (Mac).
2. Move the resulting folder to a safe place (like your Documents folder). 
   Note: If you delete or move this folder later, the extension will break.

---------------------------------------------------------------------------

STEP 2: INSTALL IN YOUR BROWSER
-------------------------------

FOR GOOGLE CHROME:
1. Open Chrome and type: chrome://extensions/ into the address bar.
2. In the top-right, turn the "Developer mode" toggle to ON.
3. Click the "Load unpacked" button in the top-left.
4. Select your unzipped folder and click "Select Folder."

FOR MICROSOFT EDGE:
1. Open Edge and type: edge://extensions/ into the address bar.
2. In the bottom-left sidebar, turn "Developer mode" to ON.
3. Click the "Load unpacked" button at the top.
4. Select your unzipped folder and click "Select Folder."

FOR MOZILLA FIREFOX:
*Note: This is a temporary install and will reset if you close Firefox.*
1. Open Firefox and type: about:debugging#/runtime/this-firefox
2. Click "Load Temporary Add-on..."
3. Open your unzipped folder and select the "manifest.json" file.
4. Click "Open."

---------------------------------------------------------------------------

TROUBLESHOOTING:
- If you see "Manifest file missing," you are likely selecting the main 
  unzipped folder when there is actually another folder inside it. 
  Try clicking one level deeper into the folders.
- If the browser warns you about "Developer Mode," this is normal for 
  manual installs. You can safely ignore or click "Cancel" on the alert.
