Houston we have a problem: ViewSourceWith under FF3b5

Filed under: firefox,viewsourcewith — dafi @ 10:46 am

Bad news for ViewSourceWith and its compatibility with FF3.0.

Due to the bug “Code running in context of hiddenDOMWindow runs unprivileged?” ViewSourceWith stopped to work when FF3.0b5 was published.

I’ve done many code modifications to adhere to FF3 requirements and now VSW 0.1b is ready.
After dozen of regression tests I’m afraid something is missed so I ask to VSW users to help me to test it deeper.

Any help is welcomed not only technical tests, for example you can share my help request in other blogs/forums.
If you would help me to test VSW 0.1 download it from here.

Tests can be done on

  • Firefox from 2.0 to 3.0b5
  • SeaMonkey
  • Songbird
  • Flock

Tests must verify

  • text box editing
  • page view source
  • css/js view
  • error console view source clicking on links
  • temp files removal at application exit

Try to

  • open more that one browser window closing the openers and verify if VSW continues to work
  • use your daily VSW usage behaviour
  • use you creativity 😉


  • Windows
  • Linux (I use Ubuntu Feisty)
  • MacOSX

Please use this post to give me feedback or better land to “ViewSourceWith Open Discussion



  1. Test of css and js view with this config. Test performed on this very page
    Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5

    Result: jss and css are duly parsed and appear in the dialog but cannot be viewed.
    alert message tells “format unknown” 😦

  2. Ouch, wrong report, it is working fine, my mistake, I did not switch to Pspad as editor so obviously xnview could not recognize a js or css file. sorry for stupid report 😦

  3. In fact the error arrives from “editor” (xnview) not from VSW
    My heartbeats have a bad moment 😛

  4. # text box editing
    # page view source
    # css/js view
    # error console view source clicking on links

    All of the above seem to work for me on ubuntu gutsy. didn’t verify cleanup. I’ll report anything here that doesn’t seem to be working correctly.

    Thanks for the fixes. VSW rocks.

  7. V0.1 doesn’t work with the new FF rc 1.
    You get a message that it’s incompatible.
