Safari Upgrade to OSX 10+ (Yosemite - Big Sur)

"My iGive Button disappeared after the upgrade?" 


After you have upgraded, you may not see the iGive Button on your browser.  If so, go to the Extensions tab of the Preferences section of Safari, you will see the iGive Button is still installed, but is no longer "enabled."  By clicking the "enable" check box and closing the preferences dialog, the iGive Button appears in the header of the browser.
