Hello I just want to say, that since Opera is Basically Google Chrome.
Opera has adopted Google Chrome Disabling Flash policy.
This How to will make pages load flash, instead of blank screens/blocks.
First Step :
Put in Browser : opera://settings/?search=flash
With the Above configuration everything related to Flash should load or work.
Side Note: .swf type links still automatically download if anyone knows a fix to this please reply, Thank you.
