'AdNauseum' and 'trackme not' Adddons have been disabled by Firefox on my Android tablet and phone. I logged on today and thhere was a message from Firefox advising that they had been disabled. I want them re-enabled. Both addons are greyed out in the 'Your Add-ons' Screen. They are still in the list of available Firefox Addons. I have uninstalled Adnauseum and attempted to reinstall. However i get this error message 'The add-on downloaded from addons-mozilla.org could not be installed because it appears to be corrupt'. I get the same message when I try to download and install AdBlock Plus and Adaware.
