I can confirm some of these points:

4.) This happens to me as well. There seems to be no specific grounds for it. I suspect that perhaps it is caused by a memory-leak.
There is no logic behind the error, except perhaps that in a previous attempt a module could not be read properly (syntax error!).
But it could be an error in Firefox.

5.) This is the standard behavious in the latest version: just scroll the code to get the breakpoint showing up.
But if you remove a breakpoint by clickink, it may not be removed from the listing at all.


I would like to take this opportunity for suggesting a new feature for Firebug: detecting a single equal sign in a conditional statement.
This is an annoying thing in the language-specification, but we have to live with it.
On the other hand it happens too often, that through a type-error there is but a single

=, which of course assigns the value instead if testing it.

Firefox could detect it and mark it as a possible cause of errors. Many high-level languages recognize the context and accept the single equal-sign. Javascript does not.

    I have posted over 10 tickets to the Bugzilla system with much success
    at getting resolution as i don't post anymore unless i have a test
    case. However, all of the most serious bugs I face on a daily basis i
    can't get resolution for because i can't come up with a test case.
    With most of issues, i am debugging my fairly complicated webapps and
    then things just stop working. It is impossible to know exactly what
    caused it, so a test case is hard to make.
     
    For a complicated app, my companies apps all have many iframes. Most
    iframes have dojo in them, and dozens of other scripts. There are
    many dom transformations and xhr requests happening all the time.
    WHen things go wrong with these kinds of apps, it is hard to simulate
    issues with simple test cases. It's hard just to reproduce them, in
    general, as i don't noticed things are broken until i need them.
     
    So, i thought i'd list all these bugs that i encounter on a daily
    basis. Most of them have been happening to me since I started using
    Firebug (1.2 or 1.3). What i am hoping is that maybe the Firebug
    developers could take the opposite approach with these bugs. Instead
    of requiring a simple test case, maybe they could test against a
    complicated app until they can reproduce some of them. If not, maybe
    others will post to this with experiences with these bugs.
     
     
    1. 'console is not defined' - this will start happening at random
    times. browser must be restarted
    2. 'net panel stops working' - net panel will stop showing any
    requests - browser must be restarted
    3. console stops working - console stops showing any logging
    4. script panel is empty - script panel will not have a script list -
    browser must be restarted
    5. clicking line number does not add breakpoint - you click on a line
    number and it does not look like it added a breakpoint, even though it
    does. the breakpoint shows up only after you click the Watch tab
    6. lockup - browser locks up and gets unresponse script errors inside
    firebugs code. must do force shutdown on browser.
    7. console shows errors from non-activated pages in other tabs. - for
    example, i might have Hotmail opened in a different tab, and i will
    any errors from it in my tab.

    Which complicated app? It's not like I can see your screen from here.
     
    I'll give you the opposite story of frustration from my side: dojo
    users complain about firebug problems but rarely report bugs with test
    cases. There are 4 bug reports related to dojo, none with test cases:

    > does. the breakpoint shows up only after you click the Watch tab
    > 6.  lockup - browser locks up and gets unresponse script errors inside

    I don't know about any reports for the first 6 items.
     
    > 7. console shows errors from non-activated pages in other tabs.  - for

    This particular one is well known to me. 1.6b1 will have another fix
    for this problem, but it's all hacks because Firefox does not support
    this feature directly.

    It's our own company's app, call webNetwork. It's basically a virtual
    web desktop, and contains dozens of apps inside it. There are public
    versions of it available, which could be used for debugging. However,
    most of the bugs i mentioned happen while i am changing code, which
    can't as easily be done on a public site.
     
    I have searched Bugzilla and came up some ticktets that may be related
    to my issues:
     
    1. 2028
    3. 2948
    5. 2647
     
    Anways, to follow up on my previous comments, my feeling is that the
    issues i face is probably common to anyone who uses a complicated app,
    because i have them so easliy. If the Firebug developers had some
    kind of 'master complicated app', (e.g. - similar to google mail)
    simple test cases would become obsolete as this app could be used to
    duplicate all of the above issues.

    None of these issues have a test case. I can't reproduce the problem
    so how can I fix it?

    We don't have any such application, so we can't duplicate any of those
    issues. If you were to provide such an application that duplicated the
    above issues, then we could fix them.
     
    One approach that I have used successfully in the past is for users to
    run with Firebug tracing and post the traces to the issues list.

    I'm not entirely clear what you mean, but I think you may be under a
    (very common) misconception.
     
    Firebug will show you where in the _data received by the browser_ a
    particular thing occurs - whether a DOM element, some Javascript, a
    CSS rule.
     
    If that item happens to be part of a server response which was more or
    less a literal file from the server (as CSS and Javascript often are,
    though not always), then Firebug may be able to point you at the file
    on the server that contains it.
    But if the server's response was generated (eg by a CGI program, or
    some PHP) then there may be no file on the server which contains the
    data you are looking for, and in any case Firebug cannot do much to
    help you find where it comes from.
     
    If I have misunderstood and this is not the problem, I apologise.
    Perhaps you would like to make the issue a bit clearer.

    thanks for the reply.
     
    what I mean when I say "go there" is this.
     
    For example, i have selected a code that needs changing on the left
    side.
    On the right side, it is shwoing me that that code is in style1.css -
    line 3 (just an example.
    When I go into my server files and hunt down this "style1.css" file,
    it looks nothing at all like
    the one in Firebug, and there is nothing on line 3 resembling the
    code that was highlited in firebug.
     
    I hope this makes more sense.
    Thanks again.

    well, i think you understand that I am not able to find files in my
    server that FB
    points me to where i can find a code.
     
    But FB has only been pointing me to CSS files.
    When I go to my server files to find the css file that FB pointed me
    to,
    it doesn't look at all like the file that FB was showing on the
    interface,
    and the code i'm looking for is not on the page anywhere.
     
    I hope this makes more sense.
    thanks for the help

    Just wanted to confirm that updating Firebug to 1.6X worked for me
    too.
     
    I had Firebug 1.5.4 installed, and it was working under FF 4.0b1.
    When I updated to FF 4.0b2 Firebug no longer worked, but after
    updating to Firebug 1.6X using the .xpi linked to above it now appears
    to be working normally under FF 4.0b2.
     
    Thanks for sharing this solution.

    Since Apple just updated Safari 5 to allow extensions, I was wondering
    if a Safari Firebug extension is in the near future. Firebug is the
    only reason why I use Firefox, so I would be so happy if it came to
    Safari.

 Topic: Firecolor :p
    "( David . RJ . 2K )" <davi...@gmail.com> Jul 27 07:31PM -0700 ^
     
    Hi!
     
    Tonight I have this idea, a "firecolor" to Firebug...
    Well, let me explain what it means.
     
    For those who develop JS Core projects (as jQuery, for instance) or
    very complex projects, there are two problems: code garbage and heavy
    codes.
    This idea is basically how the Profile, but coloring the code,
    dependings of ocasion.
     
    The fire generally is "red" :p then I suggest the low color be
    "yellow" and the high color "red". I'll explain better:
    First, you need choice the JS that you will to "firecolor", example:
    jQuery.
    Second, you will execute the jQuery test library.
    Third, you will see what part of code you don't use (white part),
    parts that are light (low cost, yellow part) and parts that are heavy
    (high cost, red part).
     
    Can exists two colors types: cost by time, and cost by execution.
     
    Example:
    - Code: var a = 1; if(a == 1) return 1;
    Color: [color]var a = 1; if(a == 1) return 1;[/color]
    - Code: var a = 2; if(a == 1) return 1;
    Color: [color]var a = 2; if(a == 1) [/color] return 1;
    Note: the "return 1" don't is executed because a == 2, not 1.
     
    Bye.

    Hi -
    I'm on the latest Firebug Alpha (18). When I click on the console
    tab, errors don't immediately show up, even if they're displayed in
    the error count in the Firebug status bar. First, I have to click on
    the "All" button, even if it already appears to be pressed.

    Hi -
    I have a number of addons installed for Firebug, among them YSlow. In
    past versions, all custom tabs came after the default tabs, a
    placement scheme that I quite liked. However, I recently downloaded
    the latest alpha, and YSlow appears as the first tab. Is there any
    way to rearrange the tabs in Firebug? Like I said before, the real
    problem is not truly being able to rearrange tabs, but awkward tab
    placement.
     
    Best Regards,
    Solly

    Hi John,
     
    Does Firebug provide data for building such outline window? Extension
    would need info about :
    - all varabiables, functions ( nested vars and fn() )
    - types of variables ( from jsdoc or other doc text - using js we dont
    have variable type )
    - private/public fn/var access ( scope info ? )
     
    I know that command line provide function list ( can you breifly tell
    how it works ? )
     
    If i can use Firebug module to get functions list build otuline view
    wont be difficult.
     
    ak

    > Does Firebug provide data for building such outline window? Extension
    > would need info about :

    Yes and no. If the variables and functions exist, yes, else not. So :
    function foo()
    {
    var bar = 1;
    debugger;
    }
    If you run the function foo() and hit the debugger stmt, then bar
    exists. Else it does not.
     
    > - types of variables ( from jsdoc or other doc text - using js we dont
    > have variable type )
     
    yes, typeof(varible). you will get object, function, etc. Not very
    useful.
     
    > - private/public fn/var access ( scope info ? )
     
    Yes, as above, if you are in a scope you can see it all, else not.
     
     
    > I know that command line provide function list ( can you breifly  tell
    > how it works ? )
     
    I guess you mean command completion? If you say
    document.
    then firebug evaluates "document" and lists the properties.
     
     
    > If i can use Firebug module to get functions list build otuline view
    > wont be difficult.
     
    I think one can list the functions per source file, but objects per
    source file will require Firefox features that have recent been
    removed.

I would not want Firebug to do this: that is not its job. There are
other tools that will (I'm pretty sure that jslint will do it)

Not languages I use. == is comparison, = is assignment. Since in many
languages an assignment returns a value, = is permitted inside a
conditional, though it may be confusing and not what you want.
I certainly don't want the language processor 'correcting' my code (JS
already gets this wrong with its automatic insertion of semicolons).
I don't want the debugger to warn me of things that its limited mind
thinks might not have been what I intended.

I agree with Colin. Stephan, it's hard to find your actual comment.

@John:
> Which complicated app? It's not like I can see your screen from here.
In his issues he always referred to his website http://www.rakovszky.eu/,
so I think this time he's also meaning this site.

@Stephan:
For me it also happens sometimes, that there's a bug in Firebug, which
I can't reduce to a small test case, because often it's hard to figure
out what is causing the bug. But as already mentioned by John the
Firebug Tracing Console is often helping in such situations.
