Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

It still won't load the graph/chart:

Had a similar problem in Chrome. Adding Yahoo Finance to the Flash-excepted sites fixed it. Does Firefox have a similar function? Where you can SPECIFY what sites you want it to ignore blocking of Flash?

Flash test Page : http://www.dhs.state.il.us/accessibility/tests/flash/video.html

The block happens as per this page look and then will have to do 2 step Authorization.

I would think that Yahoo uses HTML5 rather than Flash.

I had no problem with the finance.yahoo.com/chart link. I tried to check out the player, but it did not identify itself (flash, html5 . . .).

Start your Computer in safe mode with network support. Then start Firefox. Try Safe websites. Is the problem still there?

Flash Test Page played OK. I don't know if it's Flash or HTML5 or whatever - but when I added Yahoo Financial to the list of Flash-excepted sites in Chrome - it worked. See attached for 3-step procedure (Chrome Settings 01, Chrome Settings 02, Chrome Settings 03.jpg) I used to fix this in Chrome. This fix worked perfectly in Chrome.

FredMcD: Went to Safe encyclopedia link and found this:

" Safe mode loads a standard low resolution video driver and does not support connection to the Internet."

If I cannot get on the Internet in Safe Mode, how would I be able to: "start Firefox. Try Safe websites." ?

Am I missing something here?

Start your Computer in safe mode with network support

In most computers, there are several types of Safe Mode. The primary ones used most are; *Safe Mode: Only programs that came with the computer are started. No other programs will be started unless the user starts them. *Safe Mode with Networking: Same as above but the network drivers (internet) will also be running. This is a way to test if one of the other programs on the computer is causing the issue.

In addition to the above  :

(You'll have to scroll down some for Safe Mode with networking)

FredMcD: Started in Safe Mode. Went to Yahoo Finance. Chart still won't load (see attached).

So there's no facility and/or page or 'Setting' in Firefox where you can choose *specific* websites to allow Flash to load, like in Chrome? (That solved the problem in Chrome)

There sure is :

Page Info (click on the little 'i' in a circle, at the left side of the address bar), then click 'More Information'. Under the 'Permissions' tab : "Activate Plugins' => Adobe Flash : Uncheck 'Use Default' and check 'Allow'.

Just to make sure :

In the 3-bar menu (or 'Tools') => Add-ons => Plugins : Have you set Shockwave Flash to 'Ask to Activate' ?

Happy, Checked 'Ask to Activate'. Went to 'Permissions', "Activate Plugins', checked allow. Still didn't work. Closed/Opened Firefox, still didn't work. Re-Booted computer, still didn't work. BTW, when I click the circled 'i' now, under 'Permissions' it reads: "You have not granted this site any special permissions" - even though 'Allow' is still checked under 'Activate Plugins'.

I give up. I'll just use Chrome for Stocks analysis.

Don't give up just yet ....

You said earlier :

" Had a similar problem in Chrome. Adding Yahoo Finance to the Flash-excepted sites fixed it. Does Firefox have a similar function? Where you can SPECIFY what sites you want it to ignore blocking of Flash? "

Well, it looks like it's not just a Flash related issue ....

Have you tried Yahoo Help yet  ?

https://forums.yahoo.net/t5/Finance/ct-p/fin

When I scroll down, I see the same problem mentioned ...... with Chrome.

Happy, It WORKED! Reset Firefox Preferences to default and the Chart loads again.

Why? Who knows. But if I set a preference and it stops working again, at least I'll know.

Thanks all you guys.

Yay  ! I bet that's a huge relief and put a great big smile on your face  !

Fingers crossed it stays this way.

And by the way : well done  !

Well done both of you.
