What is the URL of that web page?

Is there a title set via the title tag in the head section in the HTML code?

To elaborate on cor-el's reply, there should be a correspondence between the title specified in the HTML code, and what appears on the tab (assuming the tab is wide enough) and what you see on the dock.

Hi,

Thanks for the quick response - I am grateful.

My website URL is .....

I've just checked and from what I can see, there isn't a title specified in the HTML code (or else I can't see for looking!)

But, the tab does show the full URL (as above) which is great, it's just that when I right click on the Firefox icon in my dock, it doesn't show the title of the page; it just shows 'Mozilla Firefox'.

I'm sure you can easily add a <title> to that and your other pages, and this will improve how they appear in search engine results as well. In the absence of a title, for example, Google will just improvise something based on the structure of and prevalence of terms in the page, which is not always what you want visitors to see on the results page.

Note that you may need to revise more code as you do not have a closing head tag and an opening body tag on the main page.
There are also a couple of stray closing tags that Firefox marks as red text in the page source.

Hi,

Thank you both very much for your help - I've managed to add a title tag and when I right click on the Firefox icon in the dock, it now shows the name of my site etc.

I'll try to clean up my code too - viewing the source information is very useful.

I'm very pleased indeed and it's all thanks to you!

Best wishes,

James.
