A modified version of Paste and Go2 is available. To install it you have to go through some steps if you have the latest version of Firefox. Download the .xpi
extension file on your system wherever you want to and now follow these steps.
Extract (unzip) the .xpi
file. It is simply a zipped file with an .xpi
extension, so you should be able to use something like unzip or Stuffit-expander (on Mac) to extract it.
Open the "install.rdf
" file with a text editor such as Notepad. Find a tagline like this showing the "maxVersion
" number (in this case 2.0, but it may differ depending on the extension):
<em:maxVersion>2.0</em:maxVersion>
Change the "2.0" to "3.0.*" or whatever you need (the * covers any minor updates to release versions). That tells the installer that the version can be installed with the corresponding version number of Firefox or Thunderbird.
Save the changes you made to the install.rdf
file.
Create a zip archive containing all the files that were in the original .xpi
file, including your modified install.rdf
file. Rename it to "myExt.xpi
" or whatever you like. The crucial thing here is to use ".xpi
" for the file extension.
Strongly recommended: before installing the extension, make a temporary backup of your profile folder or at least of the "extensions" folder inside your profile folder, which contains the installed extensions. That way, if something goes wrong, you can revert the changes easily.
Finally, install the extension: open the .xpi
file from Firefox and it should install to install it via the "File → OpenFile" menu and select the .xpi
file means the extension which you have downloaded.
If you don't want to follow this procedure then you can use disable the compatibility checker extension.
