Dear Mozilla Firefox developers, Since my Firefox was updated to the latest version, I have been having some difficulties using keyboard shortcuts on Canva (online design platform). When I use Canva for a few minutes on Firefox, keyboard shortcuts don't work such as Copy (Ctrl + C), Paste (Ctrl +V), Cut (Ctrl + X) and (Ctrl + Z). I have to restart my Mozilla to make it work again but it doesn't take long to repeat the problem. I never had such problems before Firefox update. To make sure if that is not a Canva or Windows 11 error, I used Canva on Google Chrome but never had the same problem. Sometimes when I try to copy a text, it changes the alignment of text instead of copying the text. I have also contacted Canva Support Team and they confirmed there's nothing wrong on their side. As a designer, I use Canva frequently. Mozilla Firefox is my favourite browser but I will have to stop using it if you cannot find any solution for that. I tried to reset my Mozilla completely but it didn't work. Is that a common problem that you are working on it? Thank you in advance. I look forward to hearing from you.
