This would be priceless when creating web pages and optimizing them for download speed. When this is activated, this should apply to all URL's, including local (file://). Also, the cache should perhaps be disabled in this mode. This is NOT a dupe of bug 101711 as that one deals with downloading individual files. It could be blocked by it, though. Reproducible: Always Steps to Reproduce:

Wouldn't it be better to leave this out of the already-complicated browser networking code and just run a proxy server to do it? (this won't apply to file://, but I'd really rather not slow down our file:// stuff with unnecessary checks for whether this option is activated, since that gets hit a lot during startup....)

agreed.. marking WONTFIX.

VERIFIED: People who want to test this really need a rate-limitng router and/or dialup server. There are many aspects of a slow link that would not be correctly reproducible by having a rate-limiting feature in Necko.
