&gt;the main problem is the frequent 5 to 30 second pauses while it is doing....something.<p>Oh god I thought I was alone on this. I&#x27;ve been talking to various Firefox users and nobody was able to relate with me. I usually keep Firefox open 24&#x2F;7 with around 20-30 tabs open (~6 or so pinned). Every time I am typing (like in a hangout popup window or in a HN comment) Firefox is micro-stuttering and freezing and it eats away some of the words I am typing and it becomes very frustrating. I ended up typing comments in vim and then copypasting because it was faster. It feels like typing in an SSH connection with high-latency.<p>Also when scrolling long pages (like reddit threads) the &quot;view&quot; takes a while to update so I end up scrolling down to a totally grey page which then updates with content over and over again. And don&#x27;t make me talk about twitter taking ages and setting my CPU to 100% (one core) with loud as hell fan every time I click on &quot;show 50 new tweets&quot;...<p>I have 16GB of RAM and a 2-years old top-of-the-line (back then) i7 CPU on a laptop, I shouldn&#x27;t be having these issues...
