Why can't I remove the Work Offline feature?

I keep getting an error message when I open a new Firefox window which says: Offline mode, Firefox is currently in offline mode and can't browse the Web. Uncheck "Work Offline" in the File menu, then try again.

I do not have the "Work Offline" feature checked. I can not open my Home Page or any other website. I've never had this problem before & I need to know why Firefox has stopped working. Do I need to reinstall the program or is there something else I can do?

You can create a new Boolean pref with the name network.manage-offline-status and set the value to false. You can right-click on the about:config page to open the right-click context menu and use "New > Boolean" to create a new Boolean pref.

Name: network.manage-offline-status
Value: false


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
