Unfortunately, Firefox won't let me download this onto my phone anymore. Firefox claims I need a newer version of Firefox, but I have the newest version of Firefox. Furthermore, the link that goes to the "newer version" goes to the version I have. I know this isn't your fault. It's Mozilla's fault, but I thought you should be informed about the problem. So far, this is the only add-on I can't install. :(

On a side note: I still can't believe add-ons like this are still necessary, especially now that we have devices with AMOLED displays.
