Starting approximately 2 weeks ago, I have been unable to edit and update pages in Confluence using Firefox. I can make the changes for the page without issue, but when I click "Update" it just spins forever, and displays a pop-up saying "We’re having trouble updating, We’ll continue trying to update. If it’s taking too long, refresh the page and click Update."
I've disabled UBlock Origin and Duck-duck-go privacy essentials with no effect.
I've cleared the site's caches and logged out and back into Confluence, no change.
I'm able to perform these actions with MS Edge.
