What do I do about Java?


I tried to animate this radar map on Firefox (it worked on Chrome browser) and it gave me this window (see screenshot 008).

So that got me wondering why whatever I had in my OS (Xubuntu 16.04LTS) was making the radar animate in Chrome and not in Firefox.

Also I put 'Java' into the Catfish File Finder and I have like nine million java files. So I tracked it down (see screenshot 007).

Then I wanted to install the new Java but wasn't sure which option to choose. (I chose the one circled in 009 screenshot. Is that the right one? My computer is 64 bit.)

And then I looked at the installation instructions (010 screenshot) and they looked really complicated.

Then under the 'remove old java installations' it said it was a security risk to have old java installations.

And at that point I was like, What a hassle!

What's a reasonable approach to this Java issue?

Thanks.

That's interesting, because the radar graphic in question appears to use Flash, not Java, and works fine with my Firefox IcedTea-Web (java applet) plugin disabled.

For anyone else wanting to investigate this: http://radar.weather.gov/radar.php?r...01111&loop=yes

I would recommend using the RPM or Deb package if available.

I use RPM packages for my CentOS machine & keep on upgrading JAVA using yum. Using this, I don't need to touch files manually neither do I have the problem of uninstalling old JAVA releases.

Thanks

The debugger for inspect element in firefox says....

../../images/DS.p19r0/SI.krax/latest.gif

Could not load image

And I couldn't fudge the url to force it.

I got your 008 image with chromium. And I have flash and java installed. I bet it's looking for something like a windows flash version number. Which I've hexedit'd before on the libflashplayer.so plugin to overcome issues like this.

Thanks everyone. I think I've just been looking for perfection. Not everything is going to work perfectly. I think I'm just going to live with this one. If I want to see that weather screen animated I'll switch to Chrome.

Can you check to see if you have Flash enabled in Firefox? You shouldn't need to switch to Chrome just to view that weather screen.

Seems the google hit for it gives that bum link.

http://weather.noaa.gov/radar/loop/D.../so.kbox.shtml

Changing the adobe flash version number to a windows version gave me your 008 image in firefox. Chromium got that by default for the above page.

But clicking around gets something more functional from the above link.

http://radar.weather.gov/radar.php?r...ct=N0R&loop=no
http://radar.weather.gov/radar.php?r...t=N0R&loop=yes

Both work on my default firefox with linux versioning numbers for adobe's flash. I'm not sure if that's what you were trying to get to. Base Reflectivity, not Short Range Base Reflectivity.

Thanks Shadow. I got it (animating the radar) to work on my work computer. I'll try it again on my home computer when I get home.

That's the one. Looks good. Just a side note that for security reasons it's probably better to change the Flash plugin to "Ask to activate" - it's a slight faff having to activate for websites in which you are confident and which need it, but it's safer given how much malware uses Flash as an attack vector.

Thanks hydrurga. Somebody must've slipped stupid pills into my coffee because that info I sent you from Firefox is from the computer not having the problem! I will check the problem computer later and send that info.

I'm a little scared to mess with the Firefox (re: the 'ask to activate'). There's this big warning even opening it up (Warning: you'll invalidate your license by changing anything! Something like that anyway.) So is it pretty safe to make the change? And so if I change it to 'ask to activate' when I play videos I'll get a window asking me to activate it?

You're not "messing" with Firefox by changing the Flash setting to "Ask to Activate". It's in the Preferences section, an area intended for the user to easily customise Firefox.

I think you may be talking about the about:config warning - the "This might void your warranty!" is a bit of a joke, just trying to get users to be sure about whatever they're going to do in the more detailed configuration section. That section was related to your other problem with getting new windows instead of tabs, not this problem.

Yes, if you set the Flash plugin status to "Ask to Activate", any time you are on a web page which needs Flash, you will see a message asking you whether or not you should activate the plugin, hence giving you more control.

Okay. More apologies. I gave you the screenshot (in post #9 of this thread) from the computer where the flash worked. When I checked the same thing (the plugins) on this computer there was no flash. (see screenshot 12)

So I of course set off to get the Shockwave Flash but it's not there!

Could it be the same flash Erik was talking about in the other thread? browser-plugin-freshplayer-pepper

If so, I have that in Synaptic Package Manager. However there is a warning. (screenshot 13) So I was hesitant to get it.

And yes, that was the warning (This might void your warranty!) I will definitely make the 'ask to activate' change.
