Just wanted to know if image blocking is planned any time soon for Navigator -
this is one of the few reasons why I use Mozilla as my primary browser instead
of Navigator... thanks!
FYI, you can do image blocking, even sent made by java, via OS X:
*** Bug 162240 has been marked as a duplicate of this bug. ***
We could just say image blocking is the province of proxies (personal and
otherwise) or hosts mapping and WONTFIX this.
Well, Mozilla supports image blocking - why not Navigator?
Navigator is intended to be far, far, far, far, far less complex than Mozilla.
Good point. It'd be great to have this, but I do understand that this is really
just an enhancement.
I've got a patch for this... it involved the implementation of a new class, and
some small modifications to BrowserWindowController and the BrowserWindow.nib.

Header for cookie/image blocking class
Header to a class that can block images/cookies.

Implementation of Cookie/Image blocking class
This is the actual implementation of the cookie/image blocking class. It
basically abstracts nsIPermissionManager so that you don't have know about how
that class works. Everything is done by three private methods. The public
methods (described in the header) just route the calls to those private ones.
It should be simple to use. Also, the use of the two NSMutableArrays is so that
it'll be simple to put this into an NSTableView or whatnot.
If someone would review the XPCOM stuff I used, that'd be good. I'm not
experienced with it at all, so it would probably be good if someone
double-checked that there are no leaks involved.

Changes to BrowserWindowController header and implementation
These are just the changes to BrowserWindowController. The big changes were
support for image blocking via contextual menu (a la Mozilla), and menu item
validation related to that.
Finally to finish of this patch, a few changes have to be done to the
Chimera.pbroj and BrowserWindow.nib. I can't make these changes 'cause I'm using
beta devtools whose files probably won't open in older versions.
Changes to Project Builder File:
The build settings for the Navigator and NavigatorStatic targets has to be
changed. They need the following additional search path for headers:
Changes to BrowserWindow.nib:
An additional menu item needs to be added to the ImageLinkCMenu and the
ImageCMenu. The item is the same for both menus, and should have the title
"Block Images from this Server." BrowserWindowController should also have an
additional action called toggleImagePermissions: to which the aforementioned
menu item is connected.
I apologize for not being able to do this... I just don't think the files would
work on the CVS.
Note that for right now, the only UI is a contextual menu item for image
blocking/unblocking. There is no list of blocked servers visible to the user,
but it should be simple enough to implement. I suggest a pref pane with an
NSTableView and two buttons: Add Server and Remove Server. This makes it both
simple to understand/use and functional.
The CHPermissionManager class can also handle cookie blocking/unblocking at the
API level. I haven't made a UI for it yet though. I suggest a UI almost
identical to the image blocking prefpane above. Code-wise, they'll both be very
cc: pinkerton to get his input on these patches.
simon, what d'you think? (reassign as needed.)
Do we want to forgo custom cookie/image blocking and just implement a CAPS UI à
la bug 38966?
Simon told me on IRC before I submitted my code that it might not even make it
into the tree because it might be "too advanced a feature." If that's the case
(which Simon can surely elaborate on if necessary), a site policy system would
seem to be an even more of advanced feature that probably wouldn't be used as
much by our user base (the general Mac public) due to its complexity.
Basically, all they have to do with this patch is right-click on an image and
choose "Block Images from Server." With the proposed addition/removal UI
(comment 11), it's about as simple as you can get. I'm not sure that stuff for
more complex site policies could be as simple.
Of course, I'm probably defending this 'cause I wrote the patch. More objective
opinions are probably better... ;-)
The reason I mention it is because the back-end functionality appears to already
be in Chimera, but without a UI. I for some reason, was under the mistaken
impression that Chimera didn't have CAPS, but it seems to. I tested some JS
blocking and it worked.
Certainly the server-oriented blocking you mentioned could probably store its'
rules as CAPS policies, rather than reinventing the wheel. As for the UI, some
of the proposal mockups look like they could possibly be simple enough for Chimera.
Anyway, just discussion fodder.
I don't get it - if Prachi has a patch that does this, and it won't be major
work to implement (and from my untrained eye it looks like that's the case
[correct me if I'm wrong]), why not? Chimera may be meant to be much less
complex than Mozilla, but IMHO image blocking isn't a major feature... more like
a really, really nice perk.
Greg, do you know if you can you block images and cookies with CAPS? I've been
looking at some docs and code, and I'm really just seeing stuff about
suggesting that we create our own tag (like loadImages or something).
I'm completely fine with rewriting the patch to block via CAPS, but I kind of
don't see the point. Mozilla already has API that blocks images/cookies through
use of cookperm.txt in the profile directory. I call that API through the
CHPermissionManager class so that no one has to actually learn the Moz API and
so that its easier to set up an NSTableView data source.
The only reason I would really consider changing to CAPS a better option is if
Navigator has full support for CAPS with a UI, which I doubt will happen.
smfr? pink? Any suggestions?
Actually, I guess it has nothing to do with image blocking. Duh. I thought Moz
used it to block cookies, but you're right; it doesn't.
I thought it might've used something like:
which I presumed would block cookie activity requested by www.evil.org.
Never mind. Sorry for the wild goose chase. We now return you to someone who
knows what the hell they're talking about.
I don't know if CAPS is a better solution for image blocking. Ccing some folks
who might know.
I think image blocking is a very important feature for a modern browser -- it is
currently the biggest issue holding me back from making this my full-time browser.
Like others I've discovered Chimera does to an extent respect the cookperm.txt
file and block images... but it is unreliable, and there is no GUI. It seems
this is a quite reasonable quest, especially since it already seems to "work."
Now, what would be ultimate would the ability to use wild cards. Comparable
bug/feature requests in Mozilla ask for regular expressions. I don't think this
is necessary. I think a plain-old, single-direction, pattern with wild cards is
enough. Like the astrix in filenames:
where all characters are exactly what they appear to be, with the exception of *
which is a wild card. Much easier for the user than regular expressions, and
possibly faster to implement, since you don't need the ability to search
bidirectionally, as some regexps require.

Tarball of new files for Images PrefPane
This tarball contains the new files required for the pref pane I created.
Basically, you have two directories: Images and Shared. Just copy the Images
directory into mozilla/chimera/PreferencePanes/. For the Shared folder, copy
*the files inside* the Shared folder into
The files inside Images basically make the PrefPane work. They rely on the
files inside the Shared folder, which are the interface and implementation
files for CHPermissionManager, a class that uses nsIPermissionManager to block
cookies and images. The reason this class is in the Shared folder is because if
someone wants to implement a Cookie prefpane with Cookie blocking, they can use
the class here.
Next up: patch to the Project Builder project and list of default PrefPanes

I hate to disappoint, but I'm not sure we want this level of complexity in the
default chimera download at this stage. We are considering some kind of add-on
facility, which would allow people to download and install extra pref panes.
To this end, I suggest that you upload a built version of the pref pane
somewhere, so that we can download and look at it.
This is pretty simple, so I'd appreciate it if you took a look at it anyway. The
way I've made the prefpane, it's not very complex at all, and I think a lot of
people would like it.
Still, I'm going to be posting directions to download a pre-built version to the
mailing list in a few minutes.

This works as advertised, and it was easy (at least for me) to install. Thanks,
As several people found out on the list, this doesn't work for Chimera 0.5 (due
to changes in the pref pane base classese, I think). Anyway, gotta have a recent

It's pretty clear that this isn't going to go in the final build. Instead,

I like the general idea of blocking advertising images. The problems I see are
a) Sites make their money from ads. I think everyone agrees that popups are the
spawn of satan, but inline ads while irritating are (IMHO) not actually offensive.
b) This implementation requires user configuration. Chimera generally takes the
"no configuration required or desired" attitude that is pretty much the Mac OS
X/Cocoa ideal. The popup blocker requires no configuration, it "just works". Is
there a way to implement an ad blocker that similarly "just works" without any

Pretty sure Prachi's pref pane won't work any more, but I'm working on a pane that puts UI onto the permissions manager, and one of our other devs is working on a UI for CAPS. Between those two, this ought to be pretty much taken care of.
