Problem to avoid trim code into CSS Editor

[lestdev]

Recently in the last updates of FF, I have a problem with CSS Editor.... it's really annoying to alter the structure of the source code and force to work with their coding model.

Is there any way to avoid it? I need prevent uses a trim code for my files.

For example, as professional is more comfortable write multiple rules per line and copy all content to the end file, but the editor uses a trim code when I reload the page and make the code more confusing and difficult to edit.... I have to work twice to locate the rules for editing.

It's a waste of time to adjust all files for all projects.

any idea to disable the trim-code/des-minimize of this editor?

Although, I can use css files without minimizing but the editor always modifies the structure and/or adding unnecessary spaces/blank lines.
