Joe Hewitt has just released the latest version of FireBug, a holistic debugging tool for Firefox. FireBug reports on errors and warnings in CSS, JavaScript, AJAX and the DOM, and allows you to inspect and debug each in a handy console. Another very useful tool in the web developers box, and one that I'm already finding I can't live without.

Firefox browser could not display Java applets following a recent upgrade to the Firefox browser and the Java JRE. A simple solution found.

A little background to this story. As a devout convert to the Firefox browser, I immediately upgraded to the latest release, Version 1.0.2, when it became available. Shortly after upgrading the Firefox browser I found I was unable to access my internet banking account, and was displayed a standard message from the internet banking service that my browser did not have Java installed. Necessity forced me to use IE, which worked with no problems. I had also accessed the internet banking account through Firefox only a few days previously, so there was something wrong with Firefox!

I dutifully checked my browser settings and Java was enabled. I then checked the Java control panel and noticed that the option to use Java with Mozilla/Netscape was unchecked. Found the culprit? Unfortunately not. After checking the option and pressing apply, I was informed that the action could not be completed as I did not have sufficient rights to change the browser settings. Now this was a concern, as I am administrator, super-administrator, and any other kind of controlling power over my pc, or so I thought.

Time to start on a solution, so Google in hand I went on a wild search for others who had faced the same problem. It would seem that this is a reasonably new problem (at the time of writing), as very few results were returned. Those results that were on-topic offered a selection of causes/solutions, none of which worked for me. As a result of trying each solution in turn, and scouring through the folders and files associated with both Firefox and Java, I did find what was the apparent cause of the problem in my case. On the latest update to the Java JRE, the Java Plugin dll had not been updated in the Firefox plugins folder. On a whim I renamed the existing Java plugin dll and fired up Firefox again, and hey presto, everything was working. Now I don't know why the original dll had not been updated, but it hadn't, and I don't know if this solution will work for everybody, but it did for me, and I offer this advice in the hope that it can help somebody in the same position as I found myself.

Symptoms:

  • Unable to view Java applet content in Firefox browser

Cause:

  • Upgrade of Java JRE to version 1.5.0_02 does not update Java plugin dll in Firefox plugins folder

Solution:

  • Delete previous Java plugin dll file NPOJI610.dll from Firefox plugins folder.
  • Prior to deleting the file I would suggest renaming the file (zz_NPOJI610.dll) to test that this solution works for you.

Machine Spec:

  • Windows XP Pro SP1
  • Firefox 1.0.1
  • Java JRE 1.5.0_02

Working with XHTML is all very commendable, but if the default (read wrong) MIME type is sent to the UA then you are still only sending HTML documents out to browserland. If this is the case you may as well work with the HTML doctype. So how do you send the correct MIME type for XHTML?

There are various methods depending on your situation. One can configure the server to send the correct MIME type based on file type, use httpd or htaccess files, or force the correct MIME type through the header of the page using your favourite server side code (ASP, PHP, .NET, et al). There's just one problem though – Internet Explorer currently doesn't support documents served with the

application/xhtml+xml MIME type. This is where we need to perform a negotiation between the server and browser about the media types the browser can accept, and which one it prefers. Read the rest of this entry »

Well it looks like the next release of IE7 beta will have addressed many of the bugs, issues and foibles of the IE7 public preview beta. The next release will be made available at the Mix 06 conference, and will be further released through MSDN membership following the conference. Andy Clarke has had a chance to play with a preview of the preview, and reports in his article The IE7 MIX 06 release, that almost all of the rendering bugs have been ironed out.

There are of course still a lot of issues with the level of standards compliance of the proposed production release of IE7. Just have a quick read of any of the IE7 blogs, especially the official MS blogs, and you'll see there are a lot of sceptical, jaded, and downright angry people with a lot so say in the negative. But I'm going to hang myself a little further over the IE side of the fence and say kudos to the IE7 development team for being open with the level of compliance they are aiming to achieve. There's no secret that they are not developing the leading browser, but they are certainly taking on board all bug reports and making a good attempt at fixing them before the final release.

Keep watching…
