'What does the d flag mean in a javascript RegEx?

I have a regex, that appears to work in Safari and Chrome that gives the following error in FireFox.

Error: invalid regular expression flag d
Source File: http://java.net/projects/mq
Line: 194, Column: 34
Source Code:
    var vbkpatt1=/projects\/[^/]+/di;

I had fought with this RegEx a couple weeks ago and had put it aside, so I do not have a link to the page that led me to use the 'd' flag. A pointer to a ref that includes the d flag would be a solid start to resolving my issue.

Solution 1:^[1]

There is no d flag, which is your issue :) There are:

g - Global search (multiple matches)
i - Case insensitive
m - Multiple input

Solution 2:^[2]

Are you sure it actually does something in Chrome? I tried:

/projects\/[^/]+/zyx

It accepts that as /projects\/[^/]+/, but I strongly doubt those are all real extensions. It's just ignoring them. as noted by Ken, it will keep valid flags even if invalid ones are present.

Also, I recommend you follow a good tutorial, rather than just cutting and pasting.
