Content

1. Open the file "/home/user/.mozilla/firefox/YOURPROFILE/extensions/{dd3d7613-0246-469d-bc65-2a3cc1668adc}/install.rdf" 2. Edit the file to update the maxVersion to "4.0.*": <em:targetApplication>     <Description>         <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>         <em:minVersion>2.0</em:minVersion>         <em:maxVersion>4.0.*</em:maxVersion>     </Description> </em:targetApplication> The file previously read: <em:maxVersion>3.0.*</em:maxVersion> NOTE: You may need to delete the extension's folder ("/{dd3d7613-0246-469d-bc65-2a3cc1668adc}/"), run Firefox so BlockSite is missing from Add-ons and then close the browser. Lastly, restore the deleted folder from trash so the browser can detect the changes and restart Firefox.
