TL;DR: Mozilla’s translation bot on Support Mozilla (that is currently overwriting user contributions is based on the closed source, copyright infringing LLM, Google Gemini. This is in spite of Mozilla claiming that they are at the forefront of open source AI, and belies their exhortations to choose to build open source AI and data sets. Although Mozilla has experience in attracting open contributions for data sets in projects like Common Voice, Mozilla is using a closed data set to overwrite open contributions. Since (paid) Gemini queries do not train the model, Mozillians can expect to correct errors every time the bot automatically updates an article.



Apple’s WebKit (WebCore+JavaScriptCore) was originally a fork of KHTML/KJS. They shared at the beginning but not very well. They eventually opened up their source and made changes that were more friendly to other developers. A lot of browsers and embedded renderers use WebKit, now, besides Safari and KDE based ones.
Google forked WebCore for Chromium. I don’t think they share a codebase, anymore. Edge, Opera and many embedded renderers use Chromium.
Anyway, I just think it’s interesting that most every browser out there is descended from KHTML.
