We have had many readers mail us back with requests that ask us to update the PenTestIT.Com’s WAPT FireFox Add-on’s collection as there are some add-on’s in the collection that have not been updated by their authors for some time now. We mail them back this tutorial!
Things you need for this tutorial to work:
1. A browser other than Mozilla FireFox!
2. A WinZip like utility.
Simple? Yes! It sure is! What do you do next?
1. Browse to this page with a browser other than Mozilla FireFox.
2. Select any of the OLDER add-on’s that you would like to install on your current updated FireFox version.
3. Download and save the corresponding .xpi with a browser other than Mozilla FireFox.
4. Use a WinZip like utility to open the .xpi file by selecting “Open With..” from your computer mouse’s Right Click menu.
5. Find a file –
install.rdf
in the archive and open it with your favourite text editor.
6. Search for this text in the file:
em:minVersion="2.0"
em:maxVersion="3.5.*" />
7. Simply change the em:maxVersion value to your current Mozilla FireFox version – 2.5, 3.0, 3.5 etc.
8. Save changes to the file and update the archive with the changed file.
9. Drag and drop or use any other convenient version to install your add-on.
10. Use the add-on!
Now, why did this happen? This is because, the .xpi files are nothing but a zipped archive (You can check for their “PK” header.) Secondly, when you changed the em:maxVersion value to your current browsers installation, you override the browsers check to check for the version with which the add-on was supposed to run.
That is all!
