Notes On Reducing Firefox's Memory Consumption

Posted by timothy on from the we-gave-it-post-it-notes dept.

Skuto writes "At yesterdays linux.conf.au Browser miniconference in Ballarat, Australia, Mozilla engineer Nicholas Nethercote gave a detailed presentation about the history of Firefox's memory consumption. The 37 slides-with-notes explain in gritty detail what caused Firefox 4's memory usage to be higher than expected, how many leaks and accidental memory use bugs were tracked down with Valgrind plugins, as well as the pitfalls of common memory allocation strategies. Current work is now focused on reducing the memory usage of popular add-ons such as AdBlock, GreaseMonkey and Firebug. Required reading for people working on large software projects, or those who missed that Firefox is now one of the most memory-efficient browsers in heavy usage."

    I use other browsers for development, but only Firefox to browse, it's the only browser that I feel is actively protecting my privacy.

    Any other opinions on that?

    250ish MB or RAM is hardly unreasonable and is significantly better than the alternatives. If you don't like the RAM use with Firefox then you sure as hell aren't going to be happy with the competition. I haven't seen a benchmark or other comparison in a long time where Firefox didn't trounce the competition by a significant margin.

    TFA does raise an important point that the memory consumption problems are mostly with certain add ons. The vanilla install itself doesn't have those issues.
