Cons
Con Android permission location
Today, most browser developers put 2 location permissions: 1) Precise & 2) Approximate, most people search goods & services "by typing name of specific region or place".
i.e: books library in "name of city"
So, is there any need to such permissions which is a privacy concern ?
Con Github users may track you
Con Backed by Github.com
Github is known for making it open source, and hosting tech pros, open source user, and others. This was made to be better then Chrome.
Con Too much bloat
The browser comes with 15 addons installed by default, most of which are useless or ruin one's browsing experience.
Con Mainly just an old Firefox
It is mainly a renamend older version of Firefox that comes preinstalled with some extensions.
Con Not up to date
Latest binary is still version 60.7 ESR and was last updated over a year ago
Con Requires too much unnecessary configuration to use
You have to manually delete all the bloated addons from your files (only for them to show up again when the browser is updated) and manually install some addons and themes that the browser labels as "corrupt".
Con Very slow boot time
It takes 10+ seconds for the browser to load up
Con Can't install some Firefox themes/addons
"Installation aborted because the addon appears to be corrupt".
Con Includes LibreJS by default with no way to remove it
Con Very slow boot time
It takes 10+ seconds for the browser to load up
