“I’ve been trying for weeks to upgrade FF manually by downloading and installing.”
Here is something to consider with this. If Linux will not let it install it could be that FF has now included new elements that want to acquire root access. You do not want your browser to have root access. Linux may be protecting it’s own security, safety, and you from insecure FF scripts.
I like FF but they have been handing themselves too much spy access lately. I have to find something else but NoScript absolutely has to be available as an addon. I just spent two months using Brave and it took over my box. It is not just passive, it is aggressive against other browsers and options in my machine. Now it sounds like FF wants to do the same thing and control our Operating system with root access. (still testing)
That I hate even worse... So I don’t trust brave either because of this. Librewolf was good except the last time I tried it the Linux version was very resource heavy. It was burning a lot of calories when it shouldn’t have been burning nothing at all sitting at an idle. I wish someone would start from scratch with a new unique and secure core rendering engine. The preexisting rendering engines they all build on top of are compromised at their core from the get go.
All the root security problems are coming from the fact everyone is basing their browser from WebKit, Blink, and Gecko. That old baggage needs to go. Someone needs to build a new secure open source core from scratch. Safari would be nice, but it is only available for Apple systems. Be nice if Safari would make it available for windows and Linux. But you can bet MS would never allow you to use it on Windows.
Thanks. But the issue was that I was trying to update using the Software Manager and it showed no update to FF. Using the Synaptic Package manager, I was able to update to 136.x.
