I'm using firefox browser on my mac and windows computer - both are updated and on version 75 of firefox. When I go to certain websites, the entire webpage will not load. For example, when you go on adidas.com and click on an item, you should see a chat function in the lower right hand corner. This pops up immediately on safari and chrome. However, it does not appear at all on firefox. similar issues occur on other websites as well. any suggestions on how to fix this?
