There are memory tweaks and other stuff you can fiddle with in about:config that might reduce your cpu usage e.g. if you cache more or in situations, allow more to be stored in memory before sending for more data. But a good quick area to focus on is flash. On my setup, i've got the greasemonkey addon along with a script for it called 'viewtube' Viewtube is very effective at forcing youtube/dailymotion etc flash videos to work in whatever player you choose in the list on the video and i set mine to highest definition available in html5. There's a very small learning curve for what it does - like it gives you a 'get' option to download the video, and you can set it to 'html5' or 'vlc' or 'xine' (xine is good if nothing else will work but 99% of the time html5 works great and no adverts and loads very quickly but more importantly, without flash, the cpu usage stays much lower.) The only thing i ever actually need the flash plugin for now is if i want to watch a video posted on facebook and i can't copy the youtube link and open it in a new tab in html5. While flash does once in a blue moon end up crashing the browser because of a facebook video, it never happens unexpectedly or often at all, so i went to about:config and made *dom.ipc.plugins.enabled* false. (Search for 'dom.ipc' in about:config and set the top three booleans to false.) This controls the 'plugin container' a separate process running with firefox that contains plugins (as the name implies!) so that if they crash, they don't take firefox with it. Without the process however, the cpu usage does drop a fair bit. Much less than in previous versions/previous years, but i live perfectly happily without it, maybe you might be too? Might be worth testing for yourself because it certainly made my life easier. It doesn't make sense to have it if you can circumvent your flash usage because its purely a safety net. In response to using the firefox tarballs from their site and running like that, i have done this before and you're right it is VERY simple and contained and the update packages are smaller, but i feel like it's much less integrated with the desktop unless you physically install it from a ppa or build it from source. (Although it /is /easy to make a launcher for it on the old gnome-shell desktop via alacarte, never done this for unity!)
