Not sure if it is considered as a bug but I will try here!

When editing the file %ProgramFiles%\Mozilla Firefox\application.ini like this:
Code: Select all
[Crash Reporter]

It is not important thought, the update seems to check hashes for the files. It will fail with the partial 6MB and will download the complete 40MB update. The point is, editing any configuration file in the Firefox folder will fail the update and request a complete update!

Apparently the updater check the hashes for the files which is good
, if fails it will download the complete update.

But it should exclude ini and js extensions as many users may edit them. and when patching these files it will not change the values the was changed to suit users.

What do you think? is it a bug to hash and restore configurations files?

What you say does appear to be the case.

I'd assume that Mozilla does not want one to be modifying its' files, but rather adding your own autoconfig.js / mozilla.cfg files to accomplish the same?

Code: Select all
EXECUTE PATCH application.ini
LoadSourceFile: destination file crc -936267042 does not match expected crc -661848158
LoadSourceFile failed
### execution failed
