1312832 - Running the Check Plugins routine produced message that no plugins were found, yrt there are several

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[[e-mail]]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20161019084923

Steps to reproduce:

Have been having difficulties with Firefox hanging up (not responding). 


Actual results:

As per recommendation I went in to the add-ons manager and turned off all but the Open H264 video codec from Cisco. There is a option on the page of checking to see if all plugins are up to date. I ran that and received the message that no plugins were  found.


Expected results:

Not sure.  I presume that the plugins listed on the Add-ons Manager page should have been identified.

Some of these plugins are "internal" to Firefox (OpenH264, Primetime, Widevine) and directly updated by Mozilla when update is ready, so there is no really need to put them on the plugin check page.

The plug-ins listed are:
Adobe Acrobat
iTunes application detector
OpenH264 Video Codec provided by Cisco Systems Inc.
Primetime Content Decryption Module provided by Adobe Systems
Shockwave flash
Silverlight plug-in
Widevine content decryption Module provided by Google

At this time all plug-ins are disabled. While Firefox runs better it is still hanging up, particularly when two or more tabs are opened (but not consistently). I can now exit Firefox and go back in without having to reboot the computer, and CPU usage stays at a fairly normal level.
The thing that is perplexing is that I made no changes to applications that I am aware of prior to the beginning of these difficulties.

Did you try to reset your current profile?
In addition, be sure your CPU/GPU is running fresh drivers.
