Firefox Internal Versioning
Updated with an additional column in the table (Size on disk). See comment after the table.
So we're running into a problem with our internal deployment of Firefox 2.0.0.3 that our software installer can't tell which is newer, Firefox 1.5.0.11 or Firefox 2.0.0.3. At the same time, I was asked by someone to create a list of files that could be used as "signature files" for Firefox. (For this purpose, a signature file is a file in a distribution with a unique file size that can be used to identify a particular version of the distribution.)
As a result of this effort, I came up with this lovely table.
| FIREFOX.EXE | Values are taken from the Version page of firefox.exe properties |

NOTE: I've updated this table to include a new field, Size on disk. This field is obtained from the General Properties page for FIREFOX.EXE. I got my original file sizes by looking at the file system from a command line and they correspond to Size, NOT Size on disk. I have no idea why, but I wanted to post both values here for posterity.
So first lets talk about the "signature file" problem. Unfortunately I quickly discovered that there are a few versions between which the file sizes for firefox.exe are EXACTLY the same. In particular:
- 1.0.3 and 1.0.4
- 1.0.5 and 1.0.6
- 1.5.0.5 and 1.5.0.6
- 1.5.0.10 and 1.5.0.11
- 2.0.0.2 and 2.0.0.3
I investigated further and found that just looking at disk footprint, there is no way to tell those versions apart. I'm curious to know if other products besides our Tivoli products use file size to determine signature. If this is the case, it might be worth while to have a small signature file in Firefox that simply grows by a byte with each release. This would give us a file for which we could track versioning using file size.
The second problem is much more serious for us and revealed that despite the fixing of bug 286825, there is still a major problem with Firefox file versioning. In particular, take a look at the File version (not Version) of Firefox 1.5.0.11 and Firefox 2.0.0.3. You'll see that Firefox 1.5.0.11 is 1.8.20070.31202 and Firefox 2.0.0.3 is 1.8.20070.30919. So if an application uses File version to determine which is the latest version, it will claim that Firefox 1.5.0.11 is newer than Firefox 2.0.0.3. This is what is causing our software install problem.
Hopefully we can workaround the problem on our end, but at the same time, we need to get the file versioning in Firefox done properly. Otherwise, this is just yet another hurdle for the enterprise deployment of Firefox.
This problem is bug 302046. Right?

Yes, that is the bug but it has actually gotten worse since that bug was opened.
Size on disk just includes the overhead from the file system to produce full sectors - consequently it depends on the size of your sectors.
How about doing md5sums of the firefox.exe? I'm thinking that would be a pretty accurate way to create a table...and highly unlikely to see duplicate signatures.
"depends on the size of your sectors"
maybe "cluster" instead of "sector"?
Dear collagues,
the firefox version mapping table at this site is very useful.
I have recently noticed Firefox file versions beginning with 1.9.20070.xxx .
Are these versions mapped to Firefox version 2.0 beta ?
With kind regards.
Reinhard Fuhrberg
Actually, those are the beta of Firefox 3. Here is the information for Gran Paradiso alpha 4.
Size: 7,584,768
Size on disk: 7,585,792 bytes
File version: 1.9.20070.42705
File Version: 1.9a4: 2007042705
Product Version: 3.0a4
Mike,
new file versions are rising very soon.
What product version are the following file versions mapped to (2.0.0.x) ?
1.8.20070.50813
1.8.20070.50903
1.8.20070.51502
Anytime you see a version that is not on my list, it is a nightly build. When an official Firefox 2.0.0.4 is posted, I'll put those numbers up.
Dear all,
this list is very helpful for me. But unfortunately it stops after version 2.0.0.6. Where are all the versions after 2.0.0.6? Is this site no longer updated? If yes, could someone perhaps tell me where I can found the references of the rest of the versions? Thank you so much in advance.
