Litterally once a day, firefox stops or prevents the DL of pics and videos. If they appear, they load slowly, if at all. This has been going on since Meta acquired Instagram. I believe this is a Firefox issue, not a FB or other social media issue. I used to love Firefox, now a days, not so much. Your product isn't getting better, it's getting worse, I may have to resort to MS Edge, which I detest, but at least it works.
