Do we need to check our sites on Firefox 3.5 and 3.6 both for

  1. XHTML CSS layout
  2. and sIFR and j
  3. query/javascript code compatibility?

If my xhtml and css is valid.

If i upgrade my 3.5 to 3.6 then will i have to check site with 3.5 also. or both will render in same way. if 3.6 render differently then i would not upgrade because 3.6 has not much userbase as for now it will take time.

Best Answer

If your site is written with valid xhtml and css, there will be little-to-no difference from 3.5 to 3.6. Things like sIFR will only continue to work properly if their developers adhered to strict development rules as well, which they generally do.

If you're still concerned, consult the release notes.
