Hello, Following the creation of this ticket, please find below my issues : - Why does Firefox can go into blank “black” or purple screen for no reason apart from working into multiple windows (and not tabs from Firefox) (cf. Screenshot enclosed) - Why is it not possible to download audio files ? It goes into playing mode only (cf. Screenshot enclosed) - Why do I have multiple sessions opened at the same time like for Web browsing or syncing devices, and some of them incorrectly identified or easily removable without interruption of services (in particular I notice Safari instead of Firefox Private in strict mode ? Or same device named differently like Firefox iPad or Firefox iOS 122, iPad ? Also some where not present yesterday but when looking again today it is said connected 5 days ago). In case of my device being hijacked or in parallel used in the background, can you provide diagnostic support to validate this situation ? (cf. Screenshots enclosed) Also I can notice that on some particular secure website (cf. Example in screenshot enclosed) lateral or horizontal scrolling is not correctly working with important time lagging with mice. “Without touch screen which seems to respond better, I would have throw away my machine”. Waiting for your reply.
