Subject: [PATCH] [Firefox addon] Replace a `bind(this)` statement with an
 arrow function in `PdfStreamConverter.jsm` (issue 8343)

Please note that I used the addon debugger to set a breakpoint in the `unload` function, in order to ensure that `this` still correctly refers to the `FindEventManager` scope.
