Firefox Portable For Overseas Virtual Assistant

Hi

I’ve seen Firefox Portable setups where I could download it and then once i opened it up, it would have me login to a proxy, and then I could have access to online accounts that were logged in with user names and passwords filled in.

I wanted to set this up so I could have my VAs work on my Instagram accounts without giving them the actual login information. I’d also want to block access to certain pages so that they couldn’t alter the login and steal the account from me.

Is there a video tutorial or online tutorial oh how to set something like this up?

I hope someone here can help me.

Thanks
