It can't fool the Chrome Store to let me install extensions. But the Chrome Store has extensions that allow Firefox extensions to be installed!

Pains me that Mozilla has removed INCREDIBLE extensions or simply blocked them from being enabled. For example: I have a right to view Google's cached results, which even Google agrees to by virtue of having similar extensions on its own Chrome store. But Firefox blocks Come Back Cached Link and doesn't seem to have any other similar extension to replace it.

Jealous much, Mozilla??

There are a lot of other really nice addons that pose ZERO security issues that Mozilla blocks. The devs should be ashamed.
