The bookmark names in the helphtml file are "wrong", that is, they contain a # prefix which screws up standard compliant (and thus less forgiving) browsers like Firefox.
For example, the bookmark name for the Get command is #GET, but the link in the TOC is to [url=file:///C:/Program%20Files/SourceGear/Vault%20Client/help.htm#GET]file:///C:/Program%20Files/SourceGear/Vault%20Client/help.htm#GET[/url] while in fact it ought to be to [url=file:///C:/Program%20Files/SourceGear/Vault%20Client/help.htm##GET]file:///C:/Program%20Files/SourceGear/Vault%20Client/help.htm##GET[/url]
Either link works in IE, only the second will work in Firefox.
The solution - to SourceGear and end-users alike - is simple: when viewing the file, select View Source, and replace all instances of name=# with name= (i.e. remove the # prefix for named bookmarks). Then save, and the file is now good to go in any browser.
