Do_PostBack Not Defined error when using Hint lookup in Ancestry.co.uk website.
When trying to review a 'Member tree Hint' in the Ancestry.co.uk but FireFox Hangs when selecting a member tree to view and the clicking on the 'Review Member Tree Hints' button, The Java instruction 'javascript:_doPostBack('saveButton1'),"' appears in the bottom left of the screen and Firefox does not respond. When I check the @error Console' (CNTL+SHIFT+J), the last entry shows as 'Referencerror:_doPostBack is not defined'. Works OK on IE and Google Chrome. Has anyone had a similar problem and know how to fix it???

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
