In the last few days popups within a website will not open. IE photo gallerys, logins for internet banking.
It seems to be a problem only in firefox as they will open with internet explorer
Go to Solution.
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
It appears as it was a problem with the Zone Alarm Toolbar. When this was disabled everything worked fine, when enabled no popups.
I checked my ZA for updates and installed the latest, which re-installed the toolbar in firefox. It is all working correctly.
