That was true in the late 90s, but these days a browser is actually a fully-fledged programming environment that also happens to have some incredibly sophisticated multimedia capabilities: text, images, video, audio, animations, 3d graphics, etc.&lt;p&gt;The most popular websites run quite amazing amounts of code, and JavaScript execution is usually the dominant consumer of memory.&lt;p&gt;If you want a deeper understanding, visit about:memory in Firefox you&amp;#x27;ll get a detailed breakdown of how memory is used.</text></comment>

They make is as hard as humanly possible to use bookmarks to encourage the use of a search engine every single time you go to a site thus monetizing ad views.  Typosquatters.  &amp;quot;Journalism&amp;quot; sites with one line of the article per page of spam.  Spam &amp;quot;answer&amp;quot; websites.&lt;p&gt;Memory is way, way down the list.</text></comment>
