If you get the error
Invalid file hash (possible download corruption) -261, here are a few things to try.
1. Clear your cache. Go to Tools -> Options -> Advanced -> Network / Offline Storage -> Clear Now and then try reinstalling the extension.
2. Enable third-party cookies. To do this go to Tools -> Options -> Privacy and check the Accept third-party cookies box.
3. Manually install the extension. The easiest way to do this is to just right click, Save As, and then drag the downloaded file into the Firefox window. This should initiate the installation process.
