hello art, a different avenue to explore is to get out of this site without force-closing the browser.

for example once this happens, you can press f12 to bring up the developer console - on the top left click on its settings icon, which will provide you with an option to disable javascript temporarily (see screenshot). this should allow you to navigate away from the site in question.

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?

these "exit-traps" operate via javascript - if you disable javascript they become non-functional and you can simply close the page without any popups or other hassles.

in case you don't want a session to be restored after a crash, enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named browser.sessionstore.resume_from_crash. double-click it and change its value to false.

Thank you for your help.

I clicked on the reply as a solution, but could not click on an answer to the query as to whether the reply was helpful due to not understanding the language in the selection boxes (see attached image) - sorry about that.
