Firefox and java-1.7.0-openjdk

0 votes

I have two F-19/64 computers with Firefox 22 that want "Java Runtime Environment" in order to access and several others. It appears that java openjdk is installed?

# yum install java-1.*-openjdk
Loaded plugins: langpacks
Package 1:java-1.7.0-openjdk- already installed and latest version
Package 1:java-1.8.0-openjdk- already installed and latest version 
Nothing to do

I even tried replacing Firefox 22 with 21 but apparently the requires replacing the hidden configuration files also and I didn't want to do that so put FF-22 back. I also hoped to get rid of pdf problems by using RR-21, but that's another query I guess.

Is there a solution to the Java JDK problem?

Plugin and javaws are in icedtea-web package, so please install it, the page will then work for you :) Also please remove java-1.8.0-openjdk unless you know what you are doing. It is experimental beta package :)

I did:
# yum install icedtea-web
Restarted Firefox, rebooted, the jave jdk is still not recognized.

Earlier I tried yum remove java jdk and it wanted to take Libreoffice as  a dependency! I can do that and re-install it but stopped. Perhaps that is necessary?

The JRE is just the Java (OpenJDK) runtime to run Java apps, desktop apps, and server apps, but not applets. For applets you need to web browser plugin. The web browser plugin is provided by the package

I know where your confusion comes from: in the Windows world, "installing Java" gets you the JRE + the browser plug-in, which is essentially a part of the JRE. Well on Linux it's not, because when Sun open sourced Java under a GPL license back in 2006 creating the OpenJDK project, they did not include the browser plugin component.

I have argued with the JRE developers that Icedtea-web is counter-intuitive and that at least an alias of "openjdk-plugin" should be used, but met with staunch opposition from the Icedtea devs.... so there... Install icedtea-web.

In the past I used to think why Firefox can be slow when it's loading pages. Now I've found something that makes a noticeable difference: the addon "ghostery" that blocks "trackers," which their website defines as
page elements - scripts, pixels, iframes, etc. - that are normally invisible to the user. What "trackers" seem to be all about is marketing, and apparently they've been wasting a lot of my time.

What's especially interesting to me is a list that shows the trackers that have been blocked for each website I visit. For example, the intro page for includes 20 such unwanted visitors with names like "Audience Science," "Dynamic Science," and "Scorecard Research."

It can take as long as 20 seconds to scroll the screen, which tends to scroll in large jumps, even when smooth scroll is enabled. The problem is worse when smooth scrolling is enabled, but is bad enough even when it is not.

Other applications seem to have scrolling slowed somewhat when Firefox has many windows open. It looks to me like a memory swapping issue, but I have no evidence beyond my gut. Right now Firefox has 30 tabs open on all its windows. Performance is bad, though not intolerable.
