The ram-rodding wasn't the early 00's, the ram-rodding was four/five years ago.
The factory uses a production tracking system with nested div tables and "IT" couldn't figure out how to get column widths to line up properly.
So there "solution" was Firefox-Only on all computers throughout the plant.
It was that way for only two years or so until a marketing department intern found a MISSING </div> tag in one of IT's "tables".
We now have Chrome, Firefox, and Edge all over the place, every operator is allowed to use what they are most comfortable with - it took an "efficiency expert" to convince IT that he shouldn't force people to use a web browser they are not "familiar" with.
Firefox is installed, but I honeslty cannot recall for the life of me the last time any production operator selected it over Chrome or Edge.
Pretty much everybody uses Chrome. HR uses Edge. IT uses Firefox. But everyone on the production floor uses Chrome.
When folks from the Lab run time studies, we might see Firefox in use on the production floor.
I'm no Fan Boy, don't get me wrong, I wish we had a more level playing field.
But this is the world we live in "at the moment".
H#LL, each and every time anybody has to call the "Help Desk" (located in three different countries), the very FIRST sentence they 'recite' is "Please make sure you are in Chrome."
