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: Home → New Windows and Tabs:
- Homepage and new windows → Blank page (or your personal choose)
- New tabs → Blank 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.
