Hi,
Recently updated Firefox to version 29 and after that I noticed a huge downgrade in performance. It constantly causes my system to lock up. I did some monitoring and found out that even after I freshly start Firefox, when opening a new blank tab for example it creates a new process in system activity called "Browser" that instantly eats up +1.9GB and increasing, after few seconds my mouse lags, everything locks up and lags and I have to struggle getting into console mode, login as root and kill the *******. It eats so much RAM that I can hear my HDD and even loging as root takes over 30 seconds after typing the password, I think it fills up my entire swap too. I have absolutely no issue with Chromium, Konqueror, etc, just Firefox. I have no Add-ons, clean. I reproduced the problem several times. Sometimes, plugin-container wich I know is flash does the same thing but even when no Flash content is loaded, like when opening the new tab page in Firefox wich displays the tiles with the most visited websites.
