''dupe of https://support.mozilla.org/en-US/questions/1004224 - locking'' since version 29 printing borders sometimes dont work, some of them are blank/white in version 28 everything is fine aurora didnt fix the problem. so its regress we use linux and ff from default repo cant print invoices well and other documents, they use XML so other browsers are not the solution. borders are invisible and broken, they look very ugly. instaling older version from releases tar.gz from mozilla website worked once.. next browser restart it updated itself and problem still occured.
