Viktor Nova (ID: 000000b9b23a2b95) Voted 2 ★ - Updated 03/30/2022 Pretty, but radomly hijacks the letter U when I'm typing, so it is now popping up the view source modal nearly every time I type a message. This is just too annoying, so sadly I had to uninstall it. This for sure happened consistently in Gmail as well as Twitch chat, but really it wasn't website specific and happens all over the web. I use Linux and MacOS and the same behavior happened on both. Weirdly, when this happens, the only way to get my U key back to where I can actually type the letter U without triggering the popup is to hit the Ctrl key (Linux) or Cmd key (Mac) by itself. This then lets me type the letter U for awhile before it happens again. Hope this helps.

Farzad Majidfayyaz (ID: 000000eb8f33c501) Voted 1 ★ - Updated 05/10/2021 Super useful for me as my eyes were hurting from that white background. I don't care if it "steals" Ctrl+u to display that pop-up as others have mentioned. In fact, it's much better than I can just press ESC and go back to where I was instead of needing to close a tab. I just started using it, but first impression deserves a good review :) --- Oh no, the rating went to 1 because basically the extension doesn't let you type "u" in a text box!!!

Chris Stafford (ID: 000000d56f7399f9) Voted 3 ★ - Updated 02/12/2021 Yeah, it "works", but it doesnt actually affect the `view-source:` view, I actually doubt anything can at this point. The extension intercepts the CTRL+U keystroke and shows its own darkened+syntax colored source dump in a near full screen modal.
