The negative margins on .row are causing the overflow, that's because you've removed the left / right padding on the container.

You've got the following options:
// include the padding .container { padding: 0 15px; } // or body { overflow-x: hidden; } // or .row { margin: 0; }

Hey guys. Thanks for the replies. I've checked my add ons and there doesn't seem to be anything untoward although FF does freeze so I can't scroll or select anything on my add ons page. This has happened to me before so I deleted FF but that was a year and a half or so ago so I think I'll do a malware check as you suggested.
 
Thanks!

Hey guys.
 
I've just downloaded Firefox (v26.0) from the Mozilla website to use on my 24" imac and there's a menu along the top that looks Greek or Russian but the rest of the site seems to be in English. Whenever I click on anything, the page freezes. This happened to me that last time I tried downloading Firefox on this machine about a year or so ago but it doesn't do it on my MacBook? Do I have some weird virus? See attached images.
 
Thanks!
 
 

The 2nd image has a strange looking toolbar (the blue buttons), that could suggest you have some malware or have (accidently) installed something elsewhere.
 
I'd suggest running a malware scan and removing any odd looking FF extensions. Might also be worth uninstalling Firfox and your profile data and strating afresh.

Agree with BlueDreamer.
 
That looks like a toolbar that has been added somehow.
 
If you click on the firefox menu (top left) if you're using windows (where the three dots are) I don't know about the mac.
 
Then check the addon's that are installed...

Haha, no, the larger green plus sign above the MultiQuote button! Cheers!
