If you ever figure it out I’d love to know, too. I relied entirely on Libre Office as an undergrad but missed this feature of MS Word. I currently use a combination of Scribbr and Purdue Owl but would prefer an offline and open source solution.
I do, and have used them in the past. However I’ve had issues with the profiles getting corrupted. Could be user error ;) Installing Waterfox was easier than trying to sort out my profiles.ini and so as you know, nothing is more permanent than a temporary fix :D
I didn’t see Waterfox mentioned in the article or comments, so I’m giving it a shout out now. Firefox is still my #1 browser, which I have synced to all my critical accounts, and use very cautiously, only using a few trustwothy extensions. However, when I want to explore unfamiliar domains or experiment with lesser-known browser extensions, I’ve relied on the equally dependable Waterfox browser. It’s fast, free, and 99% the same as Firefox except it’s a completely different app so you can basically have 2 Firefoxes set up and customized for completely different roles. Between the two, I can keep Chrome frozen on my phone and off my desktop (although I have a portable Chromium on USB for emergencies).
