Hello, Stephan! My name is Alex and I will be assisting you today. So, ad blocker is still showing as enabled even though it is disabled correct?

Make sure you are not blocking content.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Many site issues can be caused by corrupt cookies or cache.

• How to clear the Firefox cache {web link}

Thanks for your prompt reply None of the above suggestions solved this issue. Starting Firefox in Safe Mode didn't change the behaviour. I don't work in Private Mode When disabling Smartblock as suggested and restarting Firefox the behaviour remains teh same. Clearing the site cookies, resets the sites allowed page view counter. The popup is generated by the site, as you can see in the attached pictures I set the tracking protection to OFF for this website.

Continued ... I consult this site very regularly and it already was mandatory to put the site in the exception list in order to have full access and set tracking protection off. It's recently that they apply this new technique against adblocking. The site is fully available from Chrome webbrowser but as Firefox is my all time favorite webbrowser I hope this issuecan be solved.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

• https://developer.mozilla.org/en-US/docs/Tools/Network_Monitor

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

You can check the connection settings.

• Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

thanks to all contributers for your tips. I found the solution in my antivirus program whos anti-banner was enabled and generated the blocking behaviour. Disabling anti-banner for spanishdict.com solved it.
