@edwardqiu Keep Dapps the same. Everything else looks good.

Hey, @rebron. Since this is my first time contributing here, it took me a while to get my dev environment set up.

I've made the changes here. I also tested all of them manually on Ubuntu 16.04, except for the following changes:
Appearance -> Themes -> "Open Web Store", because the text change is not reached because of this code block.
Appearance -> "Pressing Tab on a webpage", because this text change is also not reached because it is within this code block.

For the exceptions, would there be someone with macOS be able to checkout my branch and test it?

I've also noticed on Linux - there are a few more things that may not be following sentence casing. Would you like these things to be changed to follow sentence casing as well?

I noticed this in the mentioned text changes the & is being escaped in: Version 1.9.72 Chromium: 81.0.4044.138 (Official Build) (64-bit)

@jonathanKingston that's a pretty old version - I think we've fixed it since then. Can you please update Brave and report back if it's fixed?

[jonathanKingston]

Ah so it is :') thanks, I thought I was on the auto update path. thanks!

Confirmed, it's fine now. Sorry for disturbing!

[bsclifton]

@jonathanKingston no worries - got me noticing brave/brave-core#5631 which somehow got past the radar (so many PRs!). Saw that got approved- just needs a rebase. Will try to sort that out
