1377705 - Reduce app size by compressing included PNG files and removing unused ones

Status: RESOLVED INVALID

(Firefox :: General, enhancement)

Description

[Andreas Bovens [:abovens]]

We should compress all PNG files used for the UI with the ImageOptim tool (https://imageoptim.com/mac)

I unzipped both omni.ja files and got 816KB of savings, using ImageOptim's "Insane" optimization level.

There are also a number of unused (afaict) theme files that take up a lot of space "1.header.png", "2.header.png", etc. If we remove those, we shave off around 1MB of the binary size.

Is that actually lossless?

Those files are not unused, they're part of the default set of lwthemes that we ship. Even the files for themes we already unshipped unfortunately cannot be outright removed - see bug 1370919 for more details.


X-ref bug 1316187 for an easy list of other files that we might be able to remove (and individual bugs for some of those).

Marking this as invalid since both reported issues are duplicates (of bug 1316187 and bug 1234008), hence this bug isn't really actionable. Feel free to follow up on the respective bugs if you feel like there's something we can improve on it.

Please file one issue per bug in the future, that makes fixing and/or duping much easier :)

Thanks!
