When opening a new tab, the 'homepage' presented in the new tab is a Yahoo homepage. If however, I open a new session of Firefox rather than a new tab, I get my normal Google homepage.
Go to Solution.
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
Thanks, Cor-el, your help is much appreciated.
You solved by problem.
