pictures load slowly, white from top
I'm running Windows 7. I have Webroot SecureAnywhere. Starting immediately after I upgraded to Firefox Version 89.0, whenever I go to a site, and open a picture, the picture loads from the top down (as it is supposed to, I think). But- now it loads slowly (prior to upgrading to FF Version 89.0, it loaded instantaneously), and it starts loading from the top in white, as the picture "fills in." ('Wish I could take a screen shot, but- by the time I open screen snip, the picture has already loaded.) I don't have my hardware accelerator enabled. I tried safe mode. In safe mode, this doesn't occur. Also, when I use Internet Explorer, this problem does not occur. Again- this problem started IMMEDIATELY after I upgraded to FF Version 89.0. NO other changes to my computer before this problem began. What is the problem? Thanks, for any help.
