And if you don't know Vivaldi, it's a browser made by a co-founder of Opera, and it uses the Chromium engine so it's more or less Chrome: it has the same dev tools, and Chrome Extensions work on it.
As a suggestion, same way you override default icon based on regexp, it would be useful if it could override also page title; i.e using facebook, web whatsapp in the office without (visually) being noticed :)
Moreover, you could add a preset of "useful" page overrides ;)
I made a script for https://eligrey.com that dynamically shows a speech balloon emoji when it detects that any input fields on a page have been modified (and reverts to the previous favicon when all modifications are reset). I will probably add that script as an option for Favioli.
I also know the struggle but i take the effort to create a favicon for internal tools. Helps me to have one favicon on every browser etc.
Some sites do not have one. If you run a webserver with streaming logs, and point chrome to it - you'll see requests for this favicon 404.
This extension replaces missing favicons with emoji for easier visual scanning
> The practical inspiration for Favioli came from my day job. We have a lot of internal tools and sites, and they tend to either not have favicons, or have the standard Sony logo. For me this was a bit of a pain, because I love to pin my tabs. I couldn’t tell these sites apart.
why not fix internal servers?
