Many users have discovered this problem (in Firefox 30 and higher) is caused by Conduit add-ons, such as a Conduit plugin and/or a "Community Toolbar" extension.

You can check for and disable extensions on the Add-ons page. Either:

  • Command+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

(1) In the left column, click Plugins. Set nonessential plugins to "Never Activate".

(2) In the left column, click Extensions. Then, if in doubt, disable.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Does that help with the "+" button? If so, could you name the specific plugin/extension that caused the problem?
