Completely agree with this. The difference in resources used by Firefox 30 compared to Firefox 40 is just staggering. A netbook that used to run versions of Firefox 30 and below just fine now bogs down so much in newer versions of Firefox that the netbook is regularly left unusable for minutes at a time. It’s gotten so bad that I try to avoid opening Firefox as much as possible now and just use qutebrowser¹ instead. It’s extremely liberating to be able to open a browser and not have to wait a minute before being able to type anything in the address bar.<p>――――――<p>¹ — <a href="http:&#x2F;&#x2F;qutebrowser.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;qutebrowser.org&#x2F;</a>
