doesn't work in FF 111.0 firefox continued to grab downloads no button shows on toolbar at all

When I've used it, it has been extremely helpful and time saving.

Very confident and efficient

used for sometime, recently it reset the download and restart from beginning on a large file which made me frustrated. it doesn't split the file and do multi-threaded downloaded.

actually does what it claims, which is exceptionally rare, especially for an addon of this type

I do not know how to use
