Since my last post on making hosted mode work on Ubuntu, I had upgraded my laptop to Kubuntu Karmic ( in Beta 1 as of this writing ). While most things worked out of the box ( including wireless, mic / webcam, ZTE AC2726 modem ), I got a problem with a GWT 1.5.3 application again.
GWT 1.5.3 hosted mode requires libstdc++5. Kubuntu Karmic doesn’t ship libstdc++ 5 anymore.
Fortunately, the solution was simple.
Download libstdc++5 package for your architecture from Ubuntu Package Archives.
I used i386 version
Install the package
sudo dpkg -i libstdc++5_*.deb
You should now be able to run GWT 1.5.x hosted mode browser running again. ( This might work for GWT 1.6.x as well considering that both use Mozilla 1.7.1x that depends on libstdc++5)

For sometime now, we’ve been having an issue with GWT Hosted browser not starting from Eclipse and Ubuntu / Kubuntu.
The error that comes up is
** Unable to load Mozilla for hosted mode **
java.lang.UnsatisfiedLinkError: /opt/local/eclipse-3.4-SR2-jee/plugins/com.google.gwt.eclipse.sdkbundle.linux_1.6.4.v200904062334/gwt-linux-1.6.4/mozilla-1.7.12/libxpcom.so: libstdc++.so.5: cannot open shared object file: No such file or directory
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
It could be resolved by installing libstdc++5 library in Ubuntu. Ubuntu only has libstdc++6 installed by default.
You can install the dependency by installing libstdc++5 package from your package manager (KPackagekit or Adept or Synaptic ) or by running the following command in a console
sudo apt-get install libstdc++5
Once the installation is complete, you should be able to launch the GWT Hosted mode browser just fine.

Visiting your favorite sites using Firefox’s bookmarks is far too much of a chore — do you really want to do all that mousing around? Instead, you can use keywords to instantly jump to any site you’ve bookmarked. To do it, after you bookmark a site, right-click on the bookmark, select Properties, type in a short keyword (or even just a letter or two) in the keyword field and click OK. Now, to visit the site, type in the keyword in Firefox’s address bar, and you’ll jump straight to the site.

Here’s a simple way to speed up Web browsing with Firefox — turn on its hidden pipelining feature. When you turn on pipelining, you send several requests to a Web server at a time, rather than sending them one by one, so you can load multiple items on a page concurrently. By default, pipelining is turned off in Firefox, but it’s easy to turn it on:
1. Type about:config into your address bar and hit Enter.
2. In the Filter text box, at the top of the page, type network.http. A list of settings appears, as you can see in the nearby figure.
3. Double-click the “network.http.pipelining” setting, to change it to true.
4. Double-click the “network.http.proxy.pipelining” setting, to change it to true.
5. Double-click the “network.http.pipelining.maxrequests” setting, and in the text box that appears, type in 8 and click OK.
Note that not all Web servers can handle pipelining. If for some reason, you find that your performance suffers with it turned on, reverse the above steps to turn it off.
