Are there Adjustments for Adobe Flash Player?

I have firefox browser and Win 10.  I have the latest version of Adobe Flash Player installed by a Dell technician.    I have noticed no trouble with videos.   Problem is when browsing and I click on a picture to read the story every few minutes a box popsup saying "Dismiss all"  or "Continue."  Clicking either does nothing & then another box pop & then it stops working. Are there adjustments that can be made to Adobe Flash Player or is this a Win 10 thing?  Win 10 has been very aggravating.  I have had to install & update many programs several times.
