Alphabetical list selected tabs with links 

This is probably the most complicated tabs because it contains many of the basic settings.

Here we are within Preferences, making choice for Text Chat, including the colour that will be used for displaying what you and others write.

I  think all these settigs are self-explanatory.  Note the language option.

This is an alternative root to 'Preferences'.

Most of you probably will not touch this, but it is useful to know it exists.

Perhaps 'clear cache' is the most likely command you may use here at some time - but it could also be that you will never need to touch these settings.

This 'cookie' setting could be important, but 'accept cookies' is probably the default setting - the normal setting.
