2013-10-17-03-02-01-mozilla-central-firefox-27.0a1.en-US.linux-x86_64 Steps to reproduce: 1. Load a big (3 MB or more) file. Loading a video puts it into a cache immediately; downloading a Firefox usually does not for me. 2. Open about:cache and find the entry for the file. Actual results: The entry shows a hex dump for all 3 or more MB. Particularly big files cause stability issues. Expected results: There is no unexpected huge hex dump. 2008-07-01-04-mozilla-central-firefox-3.1a1pre.en-US.linux-x86_64 seems to have the problem, too, but bug 421828 was about something else. If I just save the entry, I get a huge .xhtml.part file; that seems to WFM in the latest Nightly. Maybe this bug I am filing may be considered a duplicate of bug 424307's duplicates bug 424307 and bug 428419.
