The BPIP XPI file will have the same name as the ID from the previous step.
Thanks, but I have no idea what's this XPI. I'll have to spend some time.
Even if you can download and edit .xpi files, there are different licenses with all rights reserved, so you can't edit them just like that.
But, I don't want to edit it (even though I'd appreciate if we merged the plugins into one). I just want to see how they make some things work. I'm not going to re-release BPIP, so no worries on that part.
They might have said it isn't open-source, but I do meet the criteria to study the source:
The extension works even if you browse BitcoinTalk.org without being logged in. The source code is not obfuscated and can be examined by anyone with sufficient JavaScript knowledge using developer tools built into most browsers. Same tools can also be used to check network traffic to/from the extension.
