Firefox updated to version 89.0 when I opened the browser this morning. Now, in Yahoo mail, when I open an email, in most cases the content is not displaying. There is just blank space. When I left click, hold, and scroll down the blank space, short blue bars appear where the message would normally be. I use adblocker ultimate, and I disabled this, but to no effect. Anyone else experience this issue and can recommend a fix? Thank you! By the way, I've noticed some display issues with a couple other sites, but I'm concerned about Yahoo for now since I use this account for work.
