Many Firefox addons like Laterloop do not work with the latest version i.e. version 3.5. So what should you do? Shoot an email to Laterloop? Nah! There is a workaround for this! Follow these steps:
- Save the extension (.xpi file) to your computer: right-click and select “save link as”.
- Download 7-zip, an excellent open-source software for archiving files, and install it.
- Right-click on the extension, click on “7-zip” and then on “open archive”. Right-click on “install.rdf”, select “Edit” and replace “3.0.*” with “3.5.*“. Save the file, close Notepad and update the archive.
- Now you can drag the .xpi file to your browser and install the extension.
Pretty Geeky huh? Apart from Laterloop, Google Notebook (R.I.P. for new users) can also be installed using above steps. To download Google Notebook addon, go here.
Note: This workaround works with only certain Firefox addons and not with all of them.
Excellent and useful trick. The .xpi archive can also be opened by Winzip (even if that extension is not recognized by default). Worked for me.
