How to use NSIS to add a bookmark to Firefox

[JKnives]

Howdy.

I've been working on an installer that extracts a handful of files to a client computer, but I also would like to add a bookmark to Firefox or Chrome at the end of the installation.

I've spent the past few days searching, and while I've figured out my other issues, this one has proved difficult.

I looked at it from the direction of NSIS, but did not see anything, but I also looked at Firefox and Chrome to see if there's a way to add a bookmark via command line, to see if I could do something that way and hopefully just need to adapt it to work with NSIS. However, I have not found any documentation that would let me answer that question.

I've figured that Firefox uses SQLite, and Chrome uses what I guess is a JSON blob of sorts to store bookmarks in, but is there some sort of way to add a single bookmark to them?

Things that may be relevant when discussing: I'm using HM NIS Edit on Windows 8, and for my installer, I am using MUI.nsh, as this is what HM NIS Edit offers.

Thanks in advance for any suggestions you may have.
