I'm working with Salesforce – the lightening version, with JAWS or NVDA.
I don't know why, but on certain tabs on salesforce itself, when I'm pressing "close tab" button, the browser crushing and not responding. Without screen reader it's not happening, according to sighted assistance.
We checked on my personal laptop, and on my organization laptop. We checked with Brave, Chrome, Firefox, and Edge – same result.
