I think it's why Firefox's market share is declining too. I don't recommend firefox for non-technical users anymore because of its relative complexity and incompatibility with the modern web when compared to Chrome.
I am curious as I don't relate to this and recommend Firefox to friends and family.
I don't know whether those are bugs in Firefox or if Chrome is doing something funky that causes it to work but not Firefox.
I haven’t tried using Citrix for years. It used to work fine in Firefox, but given the quality of it I wouldn’t be surprised if they’ve broken something.
