I do almost the same as you, but with Firefox under Windows. A year ago I had to switch to the beta channel because the memory leaks in the &quot;satble&quot; version would crash it on restart (I have it configured to reload the previous session).<p>A few months later problems began with beta version. Things got nasty when they tried the multiprocess architecture (which luckily has disappeared for good). Now (v 47) they&#x27;ve found a sweet spot.<p>I have also slightly modified my usage patterns to mitigate the problem:<p>* I would open one &quot;main page&quot; (HN, for example) and keep that open, refreshing and loading tabs in that window related to news, discussions, posts, etc. I&#x27;d never close this tab&#x2F;window. -&gt; (what I suspect) this would cause FF to keep hundreds (thousands?) of URLs and state in memory to respond to the Shift+T (reopen tab) command.<p>* I now close the &quot;main window&quot; more often, and thus keep this behaviour at bay. This alone must be the one thing that impacted the browsers stability.<p>* I try to keep less than 6 windows open at the same time (one with my email accounts, facebook main page, etc, another one for reddit&#x2F;HN, and then specific windows for different topics).<p>I haven&#x27;t had to modify my habits any further fortunately. But I did use to have 20+ windows with ~20 tabs each in average.
