If you look at https://www.jerrys-furniture.com/ashley_ottomans.htm, your problem is the shear number of images that all have to load up.
The roll-over images are 1MB apiece and you have 16 on the Main.

The overall payload is hitting 20MB and you have 236 HTTP requests.
On a slow connection, one could hew the wood and build your own.

MS Edge is not the problem.
You need to focus on optimising the image resolutions, avoid rollovers and reduce the number of images.
I have a 25Mb/s connection and the page download time is 10 seconds.
