Silverlight has stopped working in Firefox 12.0 but works fine in Safari. Have uninstalled and reinstalled but this didn't fix it. I also tried the font fix with Arial and Verdana but this didn't fix either.

Would appreciate any help.

Hi. I am using FF33.0 and if I watch Silverlight videos I can't minimize or change the tab without getting sound problems. It sounds like video would slow down and thus distorting the sound.

The sound stops distorting after 30sec-5min after the tab is changed or window minimized. If I change it back to the tab where Silverlight video is playing and the sound is distorting it stops immediately.

I have tried to reset FF and uninstall and re-install.

The problem is limited to FF only. Chrome and IE work fine.

Thank you for any help!

I am curious as to why the silverlight plugin ramps the fans up (3k+ rpm) when I am watching prime video's in Firefox, but when watching the same video's in Safari, the fans a pretty much the standard 2000 (2k - 1.5k) rpm. Happens with youtube too. Safari and web videos is way quieter and I guess I just don't understand why the difference.

Is there a way to get FF to throw a little less power at these video's so as to not light the fans off so much? It can really drown out the video audio depending on what it is. As it is, I use Safari for watching video's, but hate having to have 2 browsers open.

I recently had an issue with my ISP. My ping was over 1000 and my Download/Upload speeds were .07 or so. While this was going on (well before I realized there was a problem.) I was watching a movie on Amazon. Now silverlight in just firefox is broken. It keeps thinking that my connection is crap. I can not seem to fix this issue.

What I have tried to do: Uninstall/Reinstall Firefox and Silverlight Clear all Application data in regards to firefox Delete all Cookies/browsing history.


Funny thing I have tested the problem in Internet Explorer and found silverlight to be working fine. Yet when i go back to firefox it will not work.

Using firefox to watch video such as amazon prime content causes the fans on my macbook to run obnoxiously compared to Safari for some reason. I don't get it. Why? Same video in both browsers using the same plugin causes very different results.

I use XRG app to watch the temps and stuff like fan speed.

Safari running the videos uses a good amount of CPU (~70% - 90%) and CPU die temp of 71C, where Firefox will run the CPU clear up to the 150%+ range and a die temp of 85+C. The second I stop the video, I see the case temps (sensor1,2,3) start to drop pretty quickly. Is there a different version of Silverlight for firefox that is different from Safari's? I'm stuck with Silverlight for the Amazon Prime stuff.

Pretty much, video in Firefox sends the case temps to somewhere around 39-42C, nothing crazy, but with the die temps, enough to kick the fans up to the 3500-4000 rpm range watching the videos.

Safari on the other had shows case temps around 30-32C and fans that sit steady at 1999- 2048 rpm watching the videos.

Pipelight still works in Midori browser so I don't think there is a problem with an updated pipelight, or Wine. Pipelight does not show in the list of plugins in Firefox, can you tell me how to check it's status in command line, or help me get it working again in some other way? Using pipelight is very important to me. I reinstalled it as per: sudo apt-get remove pipelight

sudo apt-add-repository ppa:pipelight/stable sudo apt-get update sudo apt-get install --install-recommends pipelight-multi sudo pipelight-plugin --update

Then install the silverlight plugin:

sudo pipelight-plugin --enable silverlight


Thanks

Firefox goes unresponsive when watching Netflix or playing a certain game on Facebook.

There's no warning, no error messages. On watching Netflix, I click play and everything seems fine then the screen freezes and Firefox is suddenly unresponsive. When this happens I have to close Firefox by whatever means I can either by clicking 'X' or right-clicking up on the menu bar then selecting 'close'. I've even had to use ctrl+alt+delete to close Firefox and a few times my entire computer has froze forcing me to disconnect power. Firefox error reporting never comes up but Windows tries to search for a solution. On opening Firefox again.. sometimes the tab will try to reload and sometimes Firefox can't restore. I don't allow the tab to reload.

The same goes for when Firefox goes unresponsive when playing the game (Farmville) on Facebook.

I have refreshed Firefox. Everything is up to date. I've searched Firefox support and done what is suggested including disabling hardware acceleration on both Firefox and Flash Player. I don't know what else to do. I've tried everything and nothing has helped.

I want to watch Netflix and refuse to use a different Brwoser than Firefox. So Here's the problem: After correctly uninstalling silverlight and reinstalling it again, Netflix keeps giving me the notification that silverlight needs to be installed, although it is. I have uninstalled Firefox clean and installed it again. I went in the internet up and down and did everything, like the microsoft fixing tool, I checked if everything is up to date, I literally did everything! When I keep browsing for solution, I see that on some websites it advices me to check my addons -> Plugins and select silverlight. Now, I do remember seeing Silverlight there plenty times, but it isn't there anymore at all, it's completely missing! Please help me!

When I visit the "Check Your Plugins Page" here: https://www.mozilla.org/en-US/plugincheck/

It shows that that I Silverlight 5.1.404160, and shows it as "Up to Date."

That version has been out of date since the release of Silverlight 5.1.40728.0 back on August 11, 2015. That update fixed a vulnerability that allowed remote code execution!

Even that has been superseded by Silverlight 5.1.40905.0, released September 29, 2015.

So, why does your "Check Your Plugins" page report that an old vulnerable version of Silverlight is up to date?
