How to Use Special Sections

There are some special sections within the Firefox AppSet and most have pre-configured example values listed for how to use that section. Many also let you specify the first line as:

MODE=REPLACE or MODE=MERGE

In Figure 2, you can see Permissions tab has the default example set with MODE=REPLACE and shows some examples on how to use the special section.

Figure 2. Site to Zone assignment special section.

NOTE: If you leave the MODE line off, the default is MERGE.

Here's what each mode does:

MODE=REPLACE: This takes the existing settings on the machine, removes them, and replaces them with these entries. Use MODE=REPLACE if you want to ensure your specific settings, regardless of what the user already has.

MODE=MERGE: This merges the settings a user already has manually placed there, with the entries you have here. Use MODE=MERGE if you want to let users make changes, but also ensure that your additions make it to their environment.

Note that with some sections (like Bookmarks), MERGE is the only option and is not changeable. In the next sections we'll explore each tab and highlight anything noteworthy with examples, tips, tricks, and exceptions.
