Add-on naming in the profiles extension folder

[iamme99]

Some add-on's in the extensions folder seem to use human recognizable names. But for many others, I see names like this:

{73a6fe31-595d-460b-a920-fcc0f8843232}
{1A2D0EC4-75F5-4c91-89C4-3656F6E44B68}
{3d7eb24f-2740-49df-8937-200b1cc08f8a}
{3e9bb2a7-62ca-4efa-a4e6-f6f6168a652d}
{3f0da09b-c1ab-40c5-8d7f-53f475ac3fe8}

I would like to find out how much storage each add-on is taking but I can't use Windows Explorer to do that because names like those above don't mean anything to me.

Why can't FF enforce a naming standard for add-on's in the extensions profile folder? This would be helpful.

[Bluefang]

The extensions are named with the extension's ID, which is often a UUID. UUIDs are used because, in theory, each extension ID will be unique.

Mozilla does enforce naming standards, there's just 2 of them:
* UUID
* extensionname@organization.tld

If you want to know which extension is in which folder, open up the install.rdf in each folder. It will list the extension's name.

[iamme99]

With 70 extensions, opening each one is a bit of a chore.

I don't care of they use the UUID, but the developer should be required to append the actual extension name to the front of the UUID then.

[Bluefang]

If they did that, then it wouldn't be a valid UUID.

Extension ID schemes haven't changed since Firefox 1.5, and I don't think they're going to be changing any tie soon. And anyways, they are intended for use internal to Firefox only and not intended to be meaningful or useful to the end user.

The "correct" solution would be to write an extension that accesses the Extension Manager and prints out the name and size on disk for each extension.

[T0morrow]

Maybe something like about:extensions that lists all add-ons(disabled ones too), along with their UUID,real names and folders.Something like advanced version of about:plugins

[RobertJ]

I just wrote a script that (with FF not running) reads the size of each {UUID} directory content and reads the <em:name> in the install.rdf and then lists them. Unfortunately I wrote it in AppleScript, took about 5 minutes. I don't know if there is a similar scripting capability in WIN. Seems like there should be something.

The easy way is to enter: about:support in the address/URL bar or -> Help->Troubleshooting Information

There you will find the name of the addon/extension and the UUID

Right.Totally forgot about this

The OP also wanted the size. This AppleScript gives a list of the UUID, size in bytes and the add-on name. Of course the OP would need to move to Mac

Don't know about Apple script. Can someone make something that can be run under Windows?

[Bluefang]

You can copy/paste these into the "Code" text box in the Error Console (Tools -> Error Console), and hit "Evaluate"

These print out the approximate size on disk used by the extensions installation. I say approximate because Firefox can't measure the size of a directory, just file actual files it contains. So the size is going to be a bit smaller than it should be.

I don't see a "code text box" in the error console.

So I tried pasting the script into the evaluate box but couldn't figure out how to run it. The down arrow on the right doesn't run it.

Here is a link to shot of my error console:

[Bluefang]

You're using Console2 The code box is the unlabeled text-box on the left side. To evaluate it, click the "evaluate" button.

The text-box on the right is the search/filter (it should be labeled Search, but it looks like you're using a custom theme).

[RobertJ]

I say approximate because Firefox can't measure the size of a directory, just file actual files it contains. So the size is going to be a bit smaller than it should be.

Out of curiosity, if an extension has nested sub directories with a big jar file at the inner directory, will this miss it?

.

[Bluefang]

No, this is does not look inside of archive files (zip/jar/xpi). Why would it need to? We're looking for the size of the extension on disk, which is the size of the archive, not the uncompressed size of the files inside the archive.
