Hello: Was having some odd behaviors with FF and private browsing and download history, so I attempted to do a "reset Firefox". It says it reset successfully. Once I restarted FF, it loads the program, and displays the standard FF page. If I type in a URL or use a bookmark, it attempts to load the page, and then immediately crashes within less than a second. Tried it with a ton of different sites. Environment is as follows: OSX 10.10 (Yosemite) with all current updates. Macbook Pro Retina 15", Late 2013 (13,1) Firefox 33.0.2 I tried completely removing FF from my machine, including deleting the app itself, the plist files in the Library and the Application Support Folders. Tried deleting my profile folder as well. Installed fresh from Mozilla download site. I created a second user on my Mac, and FF works as expected for that user. Problem seems isolated to my normal user account. Any help you can give would be greatly appreciated! Thank you for your time.
