I don't know if this is related, but in 15.04 beta I got hangs and
lockups on Firefox 37.0 until I turned off the "use hardware
acceleration when available" feature under Menu -> Preferences ->
Advanced -> General tab and then restarted the browser.  I have an AMD
Radeon HD 5770 video card and the fglrx (proprietary) graphics driver.
With the "use hardware acceleration when available" on, Firefox was
using 100% of one core almost every time I changed web page.  With it
off, it jumps to 80% for a few seconds and then returns to normal.
