That sucks that Adblock Plus is a part of that, because I have that installed, and it's really nice :/
AddBlock uses lots of memory, because the stylesheet is loaded once per frame (FF bug). 4MB * N.

Alternative: block some sites entirely (on hosts file), block scripts, block flash.

See this comment:
+++—-—-—-—-—-—-—-—- Chrome Dev here. We see this (and much more) with chrome as well.
Adblock, noscript, ghostery, and other addons like them cause 90% of the issues we see in the forums.
At the very least, by running any of these you are:
Increasing memory usage anywhere from 10% to 30% increasing overall cpu usage across all cores increasing overall load time of the page by about 15% to 50% completely screwing many of the optimizations that have gone into the browser, effectively making the multi-threaded nature of the browser fight itself.
This is because these programs need to interrupt any and all http calls to check them against a big list of "no-no" domains held in memory. If it matches, they remove the element from the dom so it doesn't load and let the browser continue.
This has the effect of making every single thread sync up each time the dom is updated, so these extensions can scan the new elements to ensure they aren't loading ads/scripts. Fancy stuff like threaded compositing, network predictors and prefetchers, and batched layout rendering are all abandoned when any one of these is in play. —-—-—-—-—-—-—-—-++-
This is an interesting and logical explanation, although, instead of complaining, it would be wiser to integrate blockers more deeply, so that unwanted content doesn't get into the dom and therefore doesn't have to be removed. But that's too much dreaming, especially in regard of chrome, coming from a company that lives from abusing its users. Dpending on what you need to browse, of course, ad-blockers can be indispensable. All those music-players on blogs that suddenly shout on you with maximum volume, for example, those stupid overlays "follow us on fb", and all those millions of ads and analytics from f***ing google, that, besides of suggesting me sh*t I don't want, try to follow me trough the web without asking my permission, converting MY data into THEIR money... No no, I wouldn't surf without ad-/stats-blocker anymore.... -- Daniel Bauer photographer Basel Barcelona http://www.daniel-bauer.com room in Barcelona: https://www.airbnb.es/rooms/2416137 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
