Thanks for all the help.
I installed greasemonkey and the inspector.
Now Firefox cannot show pages in a normal way anymore, all pages are stretched out of my screen, nos crollbars.
After installing greasemonkey already trouble started.
But... when I shift and click an item I do get a list of tags. Always the same tags though...
It seems that this tool is not working so well in windows XP. I intend to proceed using the developers tool and information button. Unfortunately the developers tool was removed in the process.
At the bottom of the firefox browser it says something like:
<broadcaster label="&webdeveloper.edit.css.label;" group="sidebar" id="webdeveloper-edit-css-s
------------------------^
The rest does not fit in the screen anymore...
It si still a pity that Icannot see what is keeping myy table from being reduced to normal proportions.
