Disappointing, Not Surprising

This country is going to hell. Gamestop has decided to stop stocking Grand Theft Auto: San Andreas. Probably because parents might buy this game for their kids, and it has (shock) sex in it now accessible via a difficult to apply mod (on the PS2 at least). I guess using a prostitute, killing her and taking the money back, massacring pedestrians and stealing things is fine family fun, but consensual sex isn't? For shame, Gamestop. You try and act like you're above this, but instead you show how unenlightened you actually are.

Desktop Linux

Asa has been blogging lately about the flaws in desktop Linux and some of the things it needs to do. This is something I've been interested in for some time - although I'd go further than Asa and say a truly seamless install would achieve equivalent compatibility that OS X achieves - install into NTFS, run Windows apps from the shell via double click, and reading resources from the Windows executables for display in the shell. Users should be able to transition what is effectively a new "shell" and still run all their productivity apps - MS Word, Photoshop, etc.

Version Number Changes

There was a Slashdot thread today “Firefox 1.1 Scrapped” ...

nothing is scrapped, this is just a version number realignment. Given the feature content of what we were going to call 1.1 - more than 12 months of new Gecko features including SVG, Canvas etc, many application functional enhancements etc this felt more like a 1.5 to everyone than a 1.1. So we've decided to rebrand the release Firefox 1.5, and once that is released (we're not pushing it out to accommodate more big features that weren't on the 1.1 plan) focus our efforts on a compelling 2.0.

For more information, read the product roadmap.

Firefox Enterprise Notes

I had some Enterprise deployment thoughts today.

Deploying with Extensions

If you're deploying Firefox 1.0 across your corporate network you may be wondering how to deploy extensions with Firefox. Firefox has the ability to install extensions in the Application directory for all users on the system using a command line flag, but there was never a way to cleanly uninstall Extensions.

Today, I had an idea - in a corporate network situation, it is generally assumed that the system administrators will be controlling the content of the application directory (in e.g. C:\Program Files\Mozilla Firefox) and that the user will not be installing many Firefox Extensions there - since it requires them to use the command prompt and most just use the web install into the profile directory. Based on this likelihood I decided it'd be acceptable for the system administrator to be able to periodically trash the contents of the c:\Program Files\Mozilla Firefox\extensions directory and rebuild it.

So, without further ado:

Installing Extensions

  1. Install Firefox from your system administration system. Remember where you installed firefox.exe to.
  2. Place the extension xpi somewhere on the system, e.g. a temporary directory.
  3. Run firefox.exe with the -install-global-extension command line flag. e.g. firefox.exe -install-global-extension C:\path\to\extension.xpi Repeat for every extension xpi file.

Uninstalling Extensions

To uninstall an extension with GUID {FOO}:

  1. Enumerate the C:\Program Files\Mozilla Firefox\extensions\ directory. For every subdirectory that has a name that matches a GUID pattern, add to a holding array if the GUID name does not equal {FOO}.
  2. Remove Extensions.rdf (or move it aside)
  3. Remove installed-extensions*.*
  4. Write a new file installed-extensions.txt in this format: theme,{GUID} extension,{GUID} for each item in the "good" array (these are items you're not uninstalling). Don't forget the default theme, whose line should start something like this: theme,{972... otherwise if users install other themes they won't be able to switch back to the default one.
  5. Run firefox.exe -register as administrator to cause the Extensions.rdf file to be regenerated.
  6. The item you removed will be gone.

Extensions.rdf in the application extensions directory holds a set of metadata about all extensions installed there. Do not try to hand parse it - it is RDF/XML and its structure is not deterministic. Rather, use the process described above to rebuild it based on a known "good" set.

Firefox 1.1

Firefox 1.1 will make all of this simpler. With Firefox 1.1 -install-global-extension still works, but the uninstall approach listed above does not apply (and should not be attempted, as the files mentioned do not exist).

The easiest way to install an Extension in Firefox 1.1 is to install it somewhere on the user's hard disk, e.g. C:\Program Files\My Firefox Extension\ (with a directory hiearchy under that that matches the extension structure within the XPI)

Set a string value under this registry key under HKEY_LOCAL_MACHINE:

SOFTWARE\Mozilla\Firefox\Extensions

ID=C:\path\to\extension\dir

where ID is a valid Extension ID, e.g. foo@bar.com or {GUID}
and the path is the path to the extension location.

The first time each user runs Firefox, the Extension Manager will detect the location and register the Extension there. To uninstall, you simply unset the registry key and remove the files. That's it!

MSIs

We will need to provide high quality MSIs to aid corporate deployments. The install system may change significantly in the 1.5-2.0 timeframe with the rebundling of Firefox using XULRunner. That will be very exciting.

Configuration

We should come up with a way to reflect preferences into some sort of system that works with existing network configuration tools, e.g. by using the Windows Registry. The days when we can expect every Windows network to special case an install of Mission Control Desktop to handle preference management are probably over. Other solutions for other platforms should be devised, in addition to our existing Pref Locking/MCD approach.
