Installing MATE desktop changed my firefox homepage -- how do I undo this?


I installed MATE desktop on 18.10 and it changed my FF startpage to a search page with the MATE logo. How can I undo this?


Same here and I've tried to change it back to my original home page under Firefox preferences but it won't save


At first restore the permissions of Firefox's folders:

sudo chown -R $USER:$USER ~/.mozilla/firefox ~/.cache/mozilla/firefox

Then try again to set it from Firefox's Preferences: HomeNew Windows and Tabs:

  • Homepage and new windowsBlank page (or your personal choose)
  • New tabsBlank page (or your personal choose)

And only if manual settings does not survive after reboot, then remove corresponding files from terminal with

sudo rm /usr/lib/firefox/ubuntumate.cfg
sudo rm /usr/lib/firefox/defaults/pref/all-ubuntumate.js

You can always bring this behaviour back with

sudo apt-get install --reinstall ubuntu-mate-default-settings

Reference link: Ubuntu MATE always forces search start page in Firefox


Uninstalling ubuntu-mate-default-settings did the trick. Thank you! I must say that is a fairly unfortunate choice made in that package -- a default being a hard-to-impossible-to-change change in the browser homepage.


You should uninstall the whole ubuntu-mate-default-settings package, but simply remove two files instead.

Also note that I can't reproduce the issue on clean Ubuntu MATE 18.10 VM, I have changed settings inside Firefox and they were saved normally.
