Recently I was able to both use http://remix.ethereum.org or https://remix.ethereum.org, but today I was not able to direct by browser to the unsecure version of remix. The reason I need to do so is because I have many contracts there and I would like to access them and eventually transfer them to the "secure" version.

I checked the request sent to remix with http and the response is a 301 Moved Permanently to https. I also receive the error message: "You are using an https connection. Please switch to http if you are using Remix against an http Web3 provider or allow Mixed Content in your browser.", but this doesn't give me a clue on how to solve the problem.

Is there a way to force remix to use http instead of https? I'm using a Chrome browser on a Mac.
