Firefox fixes save gigabytes of memory on image-heavy pages
Like many of the other Firefox memory changes, this one leaves me feeling a little ambiguous. On the one hand, obviously keeping memory usage down is good. On the other hand, waiting to decompress/decode images until they are visible to the user means that there are obviously going to be performance trade-offs (and also, obviously, design/engineering trade-offs).<p>Speaking just from my personal usage: I don't think there has ever been a time where delaying the image decompression on a page would ever have had any utility for me (at least from a memory standpoint). On the other hand, there have been plenty of times when eagerly performing image decompression would make my browsing a bit smoother.<p>All in all, it seems (from a not-particularly-in-touch outsider perspective) as if Mozilla went from being totally dismissive of memory complaints to being hyper-responsive to memory complaints with no (publicly stated) rationale behind the change. It would be interesting to see the reasoning behind this (if only from an intellectual standpoint), particularly given that in many cases I tend to feel that it would have been better to simply be a bit more diplomatic when rejecting memory-based bug reports.
