Why does my browser seem to keep going into slow motion whenever I use Yahoo mail for more than a few minutes?

I have Win 8.1 and Firefox 39 on a Dell Inspiron 15 (AMD A6). I have had the same results on Internet explorer. It seems like whenever I am typing away at an email for more than 20-30 minutes, it all just grinds down to a halt, the cursor stops blinking and as I type the screen only updates ever few seconds. Corrections are a *****. As is emptying my spam and deleted folders.

If I had to guess, I would suspect the problem is an ad that Yahoo is running every so often, some script going wild. Once it happens the only thing I can do is close the browser and relaunch it.

I have the same system you have and I have the same problems. I have contacted Firefox and followed MANY steps to solve it. No success.
I use Firefox for other things...not email.
for the most part I use Google Chrome, which seems to work best with Yahoo. Below is some helpful info on browsers that work best with Yahoo

Some problems can only be resolved using a different browser.
You can always go back to see if the problem has corrected

"Why does my browser seem to keep going into slow motion whenever I use Yahoo mail for more than a few minutes?"

I wish this was the venue to report bugs.

Try composing in a word processor, then cut and paste into the browser (which was minimized). See if that helps you...

[EDIT: "Its a good work around BUT I would have to close the browser"

No, if you minimize it, it should not call up new ads, and/or do so at 1/10th the rate.

"as when is goes slow, the whole system goes slowly. So even having it open in the background will probably be cause my problem."

Try it before you malign it. You are right, they have found a way to produce a memory leak in some gross way, and we can only wait until they fix it.

Or you could try an ad blocker, since they seem to say that ads are a Bad Thing the way the implement them, and their advertisers don't mind crashing your computer. Clearly that was not the intent, and they may eventually fix the problem, but this is not the venue to report it.

So all I can give you is a workaround.
