Alternatives to FireWatir working with Firefox 4 or higher

It seems, from what I read, that we will not have a JSSH for Firefox 4, and therefore no FireWatir. I have several script开发者_JAVA百科s that run well on FireWatir, and of course I would like to update my Firefox to v4. I would hate to rewrite all my scripts in a different system, since it would take a lot of efforts. I don't like the idea to switch to IE; the main reason is that I can set Firefox to save all files to a specific directory, while I cannot do the same with IE. What is the solution to get all my FireWatir scripts to run with the minimum effort with Firefox 4?
