Yeah definitely. I have to use mastering physics from pearson, and I feel the bloat when loading from my phone on firefox. I get two different blocked up messages everytime. A banner that says linux is unsupported, and to use safari instead (on android at least).

Then once I'm in, the whole UI feels a bit sluggish. This is all on a Pixel 8 btw. On my older tablet, I can't even the read the textbook without giving up due to frustration.
