{972ce4c6-7e08-4474-a285-3208198ce6fd}.xpi file type

[Frank Lion]

For linux, this xpi is special and cannot be open (not a "normal" xpi).

FFS.

Open it in a simple text editor, like gedit, and it'll show you the text of the Firefox default theme stub. Originally the whole theme was there, but then most was moved to omni.ja

Before you get too frightened, the <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id> mentioned in the text means Firefox itself.

There are so many windows users investigating the file type of {972ce4c6-7e08-4474-a285-3208198ce6fd}.xpi that this should be reminded to clarify:

1 - the file type of a file is not determined at all by the ".xyz" letters of its name; Linux even doesn't care at all of this .xyz extension.
If a real/true gif image.gif file is renamed image.jpg, image.jpg is still a gif file !!

2 - 7zip is absolutely not a file type, but a tool to open compressed files, which file types can be:
7z, ZIP, GZIP, BZIP2, XZ, TAR, APM, ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, LZMA2, MBR, MSI, MSLZ, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR et Z.

Linux has just one command to identify the file type which is simply: file <filename>

For windows, there is tool called TrID [File Identifier] which can be downloaded here: http://mark0.net/soft-trid-e.html
I cannot try it on windows because no windows available (no result on linux).

There is something wrong in the file header of Firefox xpi files which headers start by: "00 00 00 00 50 4B", while extension file headers start with "50 4B".
Bug or not, I don't know.

I remind that the question / the subject is just: what is the file type of {972ce4c6-7e08-4474-a285-3208198ce6fd}.xpi (nothing more).

Code: Select all

$ file *.xpi
{972ce4c6-7e08-4474-a285-3208198ce6fd}.xpi: data
$

"Data" means that the file type is not detected. I think all linux users would confirm the same.
Now, let's see what TriD detects on "windows".
There are so many windows users it should not be difficult to verify.

And from the extensions folder in my profile:

Code: Select all

$ file *

{aecec67f-0d10-4fa7-b7c7-609a2db280cf}.xpi: Zip archive data, at least v2.0 to extract
uBlock0@raymondhill.net.xpi:                Zip archive data, at least v2.0 to extract
