When I am in a website and have the option to click to email to the site, the Firefox begins multiplying "untitled" tabs endlessly until I have to go to task manager to close Firefox, without ever connecting with the intended email.
When a website has an underlined name to click in order to email that person, Firefox goes bonkers and starts multiplying tabs called "untitled"at the top....the tabs keep rapidly appearing, and there is no way to get them to stop or even to close Firefox. If I try and open Task Manager, the Firefox screen continues to multiply the tabs. The only way I've been able to stop this is to have a split screen with Task manager open - and this allows me to use Task Manager to close Firefox. When I reopen Firefox, sometimes there is a message like - We're embarrassed and don't quite know what happened. Would you like to open withe your previous tabs? Of course I say no...but I'm not able to email or get the email address I need from the website.
