Comment 47 for bug 350407

The issue (and I don't know where I saw this comment in the first place) is that, for this problem to be corrected, either the CSS parser needs to be rewritten to allow its usage by nsWebBrowserPersist for properly parsing and replacing urls in stylesheets, or a simplified CSS parser must be written for nsWebBrowserPersist, which would result in duplicated code. The best solution seems to be a full rewrite of the CSS parser to allow proper search-and-replace for urls in stylesheets, although this will take a lot of work. If someone is willing to mentor me, I have done enough research that I am pretty sure I know what needs to be done.

As a side note, the issue in comment 46 with the "Save Complete" extension has been fixed, and although it has problems with a specific time of @import rule, it is a lot better than the save functionality provided by nsWebBrowserPersist. The extension can be found at <https://addons.mozilla.org/en-US/firefox/addon/4723>.
