Right, with some testing, i have discovered - using the "browser.places.importbookmarkshtml" will import the bookmarks.html, but wipes the users current bookmarks in the places file. Doing a "show all bookmarks" and Import html will not wipe the users bookmarks. Is there a way for the "browser.places.importbookmarkshtml" to not wipe the users data?

is there anybody that can answer this question? Is there a way of adding/merging bookmarks into firefox under an unattended corporate environment?

right - this looks like this can't be done using a Mozilla function. I had to write a script to (on screen) push buttons, to open library, import bookmarks file type the server (env var) and file location. I had to write it in Autoit 3.3.8.1. I am not going to post it here, because of our work policy, it was developed in works time, it then belongs to work. The script is near on 180 lines, took me about a week to write (not a very experienced scripter) with full error checking and window existence checking. however with the way some of the FF windows are written, there is no control items to identify and use some windows and buttons.

if you message me I might be able to guide you in the right direction

ok guys, here is the script I wrote (I called the exe file FirefoxBM.exe)- I hope it helps out. Sorry for the non-streamlined scripting, I am only a novice. I have included as much commenting as I thought so you know what I am doing, and there is backup/fallback options in here as well just in case it fails in anyway. I don't think this is my final version, I could not find a later version date, you might need to modify to suit your needs.

If you use this code in any way, please respect my work and leave my details in the release info at the top, and add your modify details underneath, thanks.

the hashes changed to numbers on this page, so you have to remove the dash infront to convert back to autoit code.

The Bookmarks.html file I created had the corp bookmarks in a folder called "- Corp -". The hyphen and space is above the the alphabet on the Ascii table so most of the time it should display on the top of the bookmarks the users have after being sorted.

good luck and I hope you get it to work
