High CPU usage on OS X 10.9.4
So I have high CPU usage of 50-70% and in safe mode goes away, however when I disable all extensions and set add-ons to "ask to activate" it shoots high when not in safe mode, I disabled themes and everything. I am at my wits end as my Macbook Pro has a Core i5 and 16GB of DDR3 RAM, with a 750GB SSD Hard drive, the hardware is perfectly fine, and firefox is the issue. I may have multiple tabs open a lot but even with 1 or 2 tabs it shoots to an average of 40-50% and as high as 140%

You can try to disable hardware acceleration in Firefox.
- Firefox > Preferences > Advanced > General > Browsing: "Use hardware acceleration when available"
You need close and restart Firefox after toggling this setting.
Already tried that, still no difference

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
After a while it spools to 100% CPU. I disabled what I thought were the trouble causers such as RSS ticker. But now I am here again with 104% CPU
