Disk cache gets deleted when Firefox restart after quit from Dock menu
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.3a6pre) Gecko/20100617 Minefield/3.7a6pre Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.3a6pre) Gecko/20100617 Minefield/3.7a6pre When I quit Firefox (in this case Minefield) and restart it I found all the disk cache gone! I've seen other bugs about this only that they always happen after Firefox's crashed. It took me a while to figure out that this only happens when I quit Minefield by selecting "Quit" from the menu of the Minefield item on the Dock. It doesn't happen if I quit it by Minefield's own menubar or hotkey. So I'm guessing that Firefox "misunderstands" itself crashed when it's Dock that closes it? Reproducible: Always Steps to Reproduce: 1. Launch Firefox. 2. Select "Quit" from the Dock menu. 3. Restart Firefox. Actual Results: Upon restart all the cache will be cleared. Expected Results: Leave the cache alone will ya? ;)
generally quitting from the dock does result in a crash/abort because we haven't managed to get the message from the dock to wind through gecko safely so that it can cleanup. I suspect the only way for it to work would be for all gecko task work to *not* be in the ui thread (thus we wouldn't have call stacks that we couldn't unwind). helpwanted (if you're interested). this is a known limitation (dupeme). i suspect to some extent, out of process geckos will mostly make this problem go away (if the cache is managed by a process which isn't the primary ui app).

I wonder if we can get away with just not clearing the cache in this case, even if we can't fix the unwinding or make the cache survive unclean shutdowns in general.
Yeah, it sounds like "quit" from the Dock (which isn't our Menu; it's an operating system menu) doesn't send the app a message saying "please quit" but rather just kills it off without giving it a chance to save things, etc... It's _very_ different from selecting "Quit" from the menu. Jesse, I don't think we can fix the cache situation here without making cache survive unclean shutdown in general.
