Nope. Nothing it is happening. I just managed to do firefox reset online. And now seems to be ok. THX.

You can open the about:config page via the location/address bar and search for prefs that refer to volunteercentre.org. You can reset user set (bold) volunteercentre.org pref(s) prefs via the right-click context menu to the default value.

Note that your System Detail list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts. The user.js file will only be present if you or other software has created this file and normally won't be present.

You can check its content with a plain text editor (right-click: "Open with"; do not double-click). The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.

You can use this button to go to the current Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
