dom - HTML source appearing different in Firebug to standard browser 'View Source' option? -

-

i have html content being generated via php.

whilst investigating css problem, noticed through firebug elements in dom not organised expected. yet, when did standard 'view source' in firefox showed correct.

i know source being displayed firebug accurate, because source presents me corresponds aesthetic issue i'm seeing on screen, i'm not sure means , how investigate further.

why happen, , source version should looking at? (p.s. have no javascript running on website.)

firebug cleans dom tree, if there's syntax bugs in raw source, won't see them in firebug (unless they're bad screws parse tree completely).

the regular view-source functionality shows page's source came server. if manipulations of dom after page loaded, won't show in view-source, that's outdated. firebug show live in-memory tree, manipulations included, clean things up.
