Reproducible: Always Steps to Reproduce: 1.open a web page 2. fire up web console (ctrl-shift-k) 3. close web console (ctrl-shift-k) 4. fire up web console again (ctrl-shift-k) . Make sure you don't reload the page you are on. Actual Results: you are presented with the message "The Web Console logging API (console.log, console.info, console.warn, console.error) has been disabled by a script on this page." Expected Results: It shouldn't. and should have all panels enabled. happens if you dont reload the page.

i'm seeing this too: 08:05:25.790: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIScrollBoxObject.ensureElementIsVisible]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: resource:///modules/HUDService.jsm :: ConsoleUtils_scrollToVisible :: line 4991" data: no]

Ha.. a wild guess from a non-mozilla-developer. 1) A new log element is created of type network. 2) As a new log element is created, it tries to scroll down by making that new element visible. 3) somehow , its forgetting to check the type and if the element is really added to the list(?) because of filtering.

I believe this'll be fixed by the "lazy console" bug. Adding it as a blocking bug.

Can't reproduce on trunk. Fixed by the lazy console?

Agreed, WFM.

(In reply to comment #4) > Can't reproduce on trunk. Fixed by the lazy console? yep. fixed by bug 587734
