Adobe Flash Plug-In Not Found in Standard User Account on Firefox 49.0.2

Since updating Firefox (yesterday) to 49.0.2, Web sites cannot access Adobe Flash Plug-In 23.0.0.185 in my Standard User (main) account. Is this a new security feature or a bug? Any work-around?

Background: When I updated Firefox (in my Administrator account of course) under Windows 7 SP1, I checked for plug-in updates, and it told me that Adobe Flash was up to date. If I run Web sites that use Flash (like speedtest.net) from that account (which I feel is a security risk), they work (after clicking to allow once or whatever). They used to work the same way from my Standard User account, but now such Web sites just tell me I need to update the plug-in. Am I doing something wrong? Do I need new settings needed for new Firefox version?

Type about:addons<enter> in the address bar to open the Add-ons Manager. Hot key; <Control>(Mac=<Command>) <Shift> A) On the left side of the page, select Plugins. Make sure the ones you want to use are set to Ask or Allow.


Thanks, Fred! Stupid of me not to have checked the Ask or Allow settings. Somehow that got changed to "Never." Easy fix!

I didn't know about your second approach, with which I'll have to experiment...

Your System Details shows no flash is installed.

Flash Player Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

Flash Player Version: 23.0.0.185 Flash Player (Linux) Version 11.2.202.637

https://get.adobe.com/flashplayer/ Direct link scans current system and browser Note: Other software is offered in the download.

https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, Win IE . . . .) Note: Other software is offered in the download.

Fred -- Did you read the rest of my question?

"...When I updated Firefox (in my Administrator account of course) under Windows 7 SP1, I checked for plug-in updates, and it told me that Adobe Flash was up to date. If I run Web sites that use Flash (like speedtest.net) from that account (which I feel is a security risk), they work..."

Also Control Panel/Programs and Features says Flash was installed on 10/16/2016, even when viewed from the Standard User account.

Sorry about that.

Type about:addons<enter> in the address bar to open the Add-ons Manager. Hot key; <Control>(Mac=<Command>) <Shift> A)

On the left side of the page, select Plugins. Make sure the ones you want to use are set to Ask or Allow.


Go to the web page. Once the page is loading, mouse to the address bar and Left click the icon. Select Permissions. In the menu, Make sure the ones you want to use are set to Ask or Allow.
