OK, I have attached a screenshot that probably won't get through the ML 
but you are on CC so at least you should get it.

I see FF using svg title in two places. The browser window title  bar as 
you describe above.
With an html document this shows the html title so this seems consistent 
and correct.

Also I see it in the browser tab. I suspect this is configurable in FF 
options so you may or may not see that.

( this is firefox 3.6.20 )

I have given up using opera for svg since it opens local svg files as 
text. A bug I reported over a year ago and remains AFAIK unaddressed. I 
have to upload somewhere and access via http so I no long bother.


I manually edited the svg as follows and FF tab and title bar now show 
the modified title with spaces.
	<g id="25u50u_25cZZ_plot_1" ><title>25u50u 25cZZ plot 1</title>

It seems FF is just grabbing the first occurrence of ANY title element, 
this may not be that logical. If the intent is to have an svg title for 
the file maybe that can best be addressed by adding a new svg element 
near the head of the file.

I just tried this between <desc> and <script> tags and it works. I 
believe that is correct usage but you may like to check.

I suspect FF picking up the plot element's title may be a bug , but 
explicitly adding a title to the file would seem to be the correct 
approach for situations where a viewer displays it. This also works with 
Opera , it is only displaying the file name as you noted because there 
is no title tag in the document. This is probably what FF should be 
doing as well.

So adding a new title tag for the document as a whole seems the right 
thing to do. A trivial mod.

Using any specified "title" option also as the base text for the plot 
titles would allow control of the text shown in the hint box you 
describe too.

(I don't think there are any distro/desktop issues complicating this.)
