Firefox 6 forces you to log into e-mail again & again, since you can't view an e-mail & simply close that tab.. I want to close the tab, not exit the function I am in. How do I uninstall Firefox 6 & go back to the previous version?

Question

With Firefox 6, you can't close the tab you are in and remain in the program; opting to close one e-mail means you are forced to exit the (e-mail) program completely and then go back into it...this is ridiculous if you are trying to read all your e-mails...not have this issue. How do I uninstall Firefox 6 & go back to the previous version?

Answer 1

I am unwilling to attempt navigation away from these sites. The pop-ups that occur on the attempt to leave a site or to close the browser are exit traps offering incentive to stay.
Once upon a time, when the internet was less dangerous, I would be willing to close the exit pop-ups. Now, after twice being infected with malware trying to close the pop-ups, I now force close whichever browser I am using.
Recently, I clicked on the red X to close one pop-up, and it installed a trojan that I had to pay to be removed. When I clicked on 'Leave' in another exit pop, it didn't exit and it turned out I was giving permission to run a script file. Now that criminals have learned these exit pop-ups can be used to force a click action, the sites using them have become dangerous.
If I force the browser to close using Task manager, Please tell me how to stop FireFox from sending me directly back to the same site because it mistakenly believes it crashed when it did not. I forced it to close because I was on a site that had taken control of my browser and was not allowing me to leave the site.
No other browser sends me back to the potentially dangerous sites. I prefer Firefox, but the new version must have a setting that allows me to get safely away from a problem site?
