The Adblock Project

[jeffw_00]

1) goto usps.com
2) select "click and ship"
3) select (at bottom right" print a sample label.
4) (with adblock installed) watch Mozilla hang...

would be really nice if you could fix this - I love adblock, but need to use this site.

THANKS!

I just performed the steps that you described and Mozilla did not crash. The page does appear to require Java to be of any use, and I do not use Java.

How did you determine that adblock was the source of the problem? What version of Mozilla are you using? Is it the latest release version?

If you have Java 1.4.x please upgrade it to 1.5 which works much better.

The site has been mentioned earlier:

Get the latest Java here:

Guys - if you go to the page

https://sss-web.usps.com/ds/jsps/ds_landing.jsp

and at the bottom right select "the "GO" under "Print a Sample Label". it WILL start a JAVA application. I can selectively make it work or fail by uninstalling and re-installing adblock 0.5 (with no other extensions installed). I'm not trying to dis adblock, which I think is a great tool, but I think you can see why I think the problem lies here. It happens with Java 1.4 and 1.5 (the only two I've tried, could be others), and I suspect isn't a Java thing at all but
somehow Adblock is interfering with the Java script.

Any suggestions on how to fix would be very appreciated.

Thanks

sorry - didn't answer everyone - I'm using Moz 1.7.7, though I have observed this since 1.7.1

Adblock does indeed cause problems with certain Java applets. This is a very old and well known bug. Unfortunately no one knows what is causing it, or if it is indeed a bug in Adblock, Firefox, or Sun's Java VM. The latest Java 1.5 works better than the older 1.4.x, but it still does not work everywhere.

I wonder if the Java people of Sun would investigate this if someone asked nicely?

[kstahl]

Good question. You volunteering for emailing them?

my apologies because
1) i did post as guest accidently
2) with the newest java, it appears to work (though it takes a long time to load the applet the first time...)

thanks guys

Hi all,

I'm experiencing a problem where AdBlock is causing my Java Applet to load twice on the same page.

The symptoms of the applet loading twice:

- Applet callbacks (init, start, stop) are all called twice (as seen via print statements in the java console)
- The resulting GUI has two instances (ie. the login dialog and app frame are presented twice).

The symptoms of AdBlock being related to the problem:

- the problem only occurs when AdBlock is enabled. Disabling AdBlock (via Firefox's control, I haven't tried AdBlock's control on the settings panel) causes the Applet to load properly (ie. only once).

I've verified this behavior on these systems:

- x86; Gentoo Linux; Sun Java 1.4.2_07
- x86; Windows XP; Sun Java 1.4.2_06
- x86; Windows XP; Sun Java 1.5.0_02

Since this is my code, I'm open to any testing/debugging suggestions. For instance, I can print trace and debug statements from the Applet.

If requested, I'll post the URL to the Applet.

Thanks.

Oops, forgot some additional specs:

Both systems (Linux & Windows) are running:
AdBlock version: 0.5.2.039
Firefox: 1.0.3

I also forgot the most important thing:
Thanks for a spectacular extension!
