Where did you get that .deb of Firefox?

From here https://packages.debian.org/sid/amd64/firefox/download

What gets me why I can't install the latest firefox and why Deepin uses such out of date version. It is a huge security issue to use old browsers but I guess none of the developers want to fix this because its been like this for years. I have been using KDE more than Deepin but recently trying to go back because of some bugs in Kubuntu.

Well if anyone knows a fix that would be great getting tired of trying every way to install a simple browser I guess it wont be in the cards for me this time

Ok.. It is simple to install Firefox Quantum latest in Deepin, but requires a little work..

1. Hit ctrl+alt+t
When terminal pops up, copy next commands one by one and execute:

2. sudo wget -O FirefoxSetup.tar.bz2 "https://download.mozilla.org/?product=firefox-latest&os=linux64&lang=en-US"
3. sudo tar xjf FirefoxSetup.tar.bz2
4. sudo mv firefox /opt/firefox
5. sudo ln -s /opt/firefox/firefox /usr/bin/firefox

After this see if installation is ok by entering 'firefox' in terminal. Without quotes..
It should launch..You can pin it to dock and use it that way if you don't want to create launcher.


Now let's create launcher for Firefox:
1. sudo deepin-editor
2. Paste this in editor:

[Desktop Entry]
Categories=Network;
Comment=Firefox Quantum
Exec=firefox
Icon=/opt/firefox/browser/chrome/icons/default/default128.png
Name=Firefox Quantum
Terminal=false
Type=Application
X-Deepin-Vendor=user-custom

3. Name the file firefox.desktop and save it to this location: /usr/share/applications

That should be it..

2. sudo rm -rf -R /opt/firefox
3. sudo tar xjf FirefoxSetup.tar.bz2 -C /opt
