I recently purchased a license for Edge to see if the experience is better, so far flawless
Have a Win 7 machine fully Patched and run in user account mode and a Win 10 po 22H2 both VDH 8.0.0.7 FF in both ... within 30 minutes either machine becomes slower then non responsive, this also affects the machines stability and responsiveness till the machine will need a reboot to get FF to work again, just closing FF then re-launching never fixes the problem, Download will often stall or fail part way through, this has become a thing over the last 4 months, have been using VDH in both Chrome and FF in the past.
Am yet to have a single download fail using Edge, nor does the browser slow then become nonresponsive, these symptoms only happen when using FF and only having tabs open for the pages I am downloading from, I use many different sites with the same outcome..
