I've had a cross-platform issue for ELEVEN YEARS with Firefox randomly not copying text into the clipboard, even when I 'cut' it-- i.e. the text disappears on cut but paste pastes whatever was in the clipboard before. I cannot be the only person with this problem. And yet the bug persists, and invariably someone pops in and tells me it's down to the extensions I have installed, despite not having any of the same extensions now that I did in 2012.

As a user, Firefox feels like hobby project, but at least it's not a Google product.
