Thank you very much for your kind answer.
I will try to let you have a run on the form, the way a visitor would do it:
The site is a Job Meta-search machine, Google personal search, (no revenues for the moment otherwise I wouldn't bother anyone here)
You begin at: http://infoprofesionales.es/pageID_10075646.html
and introduce e.g "manager", enter, then redirect to result page:
chrome:
...INFOPROFES.ROOT.../pageID_results.html?cx=partner-pub-8427202809546935:rxxaj8en2yh&cof=FORID:10&ie=UTF-8&q=manger&sa=Buscar+en+60+Portales+(escriba+empleo+y+lugar+de+trabajo)
firefox:
...INFOPROFES.ROOT.../pageID_results.html?cx=partner-pub-8427202809546935%3Arxxaj8en2yh&cof=FORID%3A10&ie=UTF-8&q=manager&sa=Buscar+en+60+Portales+(escriba+empleo+y+lugar+de+trabajo)#1346
As you see FF ads the hashtag
I redirect because the result page offers three buttons which add by JavaScript the internal Google parameter (filter:time):
&as_qdr=w week or d day or h hour (brilliant way to filter results not compromising the Google code (which is not allowed)
So now I`ll come to an end and it is really simple:
These appendixes (&as_qdr=X) are added by the mentioned buttons to the end of the URL, and (which works in Chrome) cause a reload showing the desired filtered results.
BUT: Firefox won't work, why? because FF forces a double load (you can appreciate it lowering conn.speed) adding the second time an hash tag to the end of the url.And behind that tag: none of my parmeters takes any effect.
Chrome: no hash tag = WORKS (try and press my yellow filter links at the bottom of result site)
Firefox & IE hash tag = DOES NOT WORK (try and you will see my "&as_qdr=X" parameter behind the tag, but not igniting like in chrome)
I had to lower myself writing on the site "works only with Chrome" which is ridiculous - and I spent all kind of attempts from manipulating by java the string location
, stop loading or whatever...
Never so much in vain.
It seems to lie on the hand: FF & IE load searchresults twice, first without tag then with ¿How forbid them loading twice (looks ugly anyhow).
