Mozilla is officially finally working on a tablet UI with tab strip, available now in Firefox Nightly!
Seems like you have the technical background to further investigate this 🙃.Good to know it happens on Instagram as well.
I know, but still, you don't point people to the code that is vulnerable for attacks. If you want to know more, you need to look on Bugzilla by yourself.
Maybe because it makes no sense to tell people about vulnerabilities in the code (even if they were fixed)?
Indeed, but tags are not available in Firefox for Android, if I'm not mistaken.
