Firefox incompatible plugins/add-on not working, Little Hack

• Goto the Extension download Page, Right click on the extension. then ” save link as” save it on desktop.
• Extensions in firefox have .xpi extension, change the extension from .xpi to .zip via renaming it.
• Now extract “install.rdf ” file from this zip file and open it in notepad.
• Search for following
  <em:targetApplication>
  <Description>
  <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
  <em:minVersion>1.5</em:minVersion>
  <em:maxVersion>3.7.*</em:maxVersion>
  </Description>

  </em:targetApplication>

• Now change value after  <em:maxVersion>
  new string  would be
  <em:maxVersion>3.6.*</em:maxVersion>
  as you can see in the image its saying not compatible with 3.6. thats why i changed the value to the my current firefox version
• Now save the file and add it back to the zip file.
• rename it to .xpi.
• after this either drag it to the firefox or open this with from file->open file menu.
• it will install it and it will run successfully.

if any doubt please comment below
