You are right, I'm already using ESR. I remember having Firefox and Firefox ESR as diferent entries in the menu, but it must have been another distro, here only ESR is available.
I was using all the time ESR, but then I don't have the vlc plugin, and can't find it in the repos, I have enabled non-free and tainted. Is it mozilla-plugin-vlc or I'm wrong?
Still the quesion about non-ESR versions remains, because this year ends support for version 60.
https://www.mozilla.org/en-US/firefox/organizations/Regarding additional permissions I was talking about this (I'm using the extension you pointed as example):
- Access data on all web sites
- Download files, read and modify browsing history
- Accessing browser tabs
(and there are extensions even more intrusive)
I don't think this kind of extension needs such permissions, it seems to me that the authors are monetizing this in an ethically questionable way. I asked if someone knows of an extension that does this (or adds the option in the context menu) and doesn't asks for this kind of permissions.
