Porting extension to Chrome and other browsers
I am interesting in getting your excellent extension ported to Chrome, Safari, and perhaps other browsers. Part of this will including getting them published on the respective stores for easy installation by end-users and I wanted to confirm that this would be OK with you. While it would be published under my account, I want to give you full credit as the author and I am just a footnote as someone who ported the app as needed to other browsers. If you would rather have it published under your account instead, I can just send you a pull request of changes as they are needed.
As the extension sits now, it does work under Chrome and Safari for macOS without any changes, but it has some visual glitches that could be tweaked to bring the presentation more in-line with how it looks in Firefox. In Chrome, it is too narrow and causes unnecessary wrapping. I've applied some tweaks to the CSS to fix that. In addition, there are several more changes that will be needed to bring it into compliance with Google's requirements for the Chrome WebStore as well as Apple's App Store for Safari. I have not yet reviewed Microsoft Edge or other browser requirements just yet. In any case, once it is ready for publishing, I plan to send a Pull Request to bring the changes back upstream.
