You must have the latest nightly with a fix for bug49168. Username : Mozilla Password : Mozilla Select File/Save as Save the page (main.html) to your HDD. Try to load the saved file from your HDD, the file is corrupt. I saw this in the console while I save this page : (This seems not be the problem) ************************************************************ * Call to xpconnect wrapped JSObject produced this error: * [Exception...

adding mscott and law to cc. Do one of you all know who should get this bug?

I should probably get it. What's happening is that the server is sending the data back using gzip encoding. When we save stuff, we turn auto-encoding off (so that gzip data files don't end up being saved bigger than necessary). In this case, that might not be what you want. If you run gzip -d against the saved file, you get what you want. The fix is to somehow enhance our smarts when it comes to choosing whether to suppress this auto-encoding business. Probably "save page as" should always uncompress? Or maybe it should be based on mime type?
