I have an ES1-512-P84G with a handle leak when Firefox runs

I have Windows 10

When running Forefox version 45, 46 4nd 47, even in safe mode, the number of handles for Firefox coults up forever.

I have the factory Intel HD Graphics driver version 10.18.10.4276

There is a much newer graphic driver available.

1. Does anyone else with Widnows 10 have a handle leak when running Firefox?

2. Has enyone solved it and how?

3. Has anyone upgraded to the latest Intel HD graphics deriver from Intel and it it working OK?

Thanks
