Firefox has a process manager now, open:
The process manager can also be opened with the keyboard shortcut
or from More Tools -> Task Manager in the menu.
You can take screenshots directly in Firefox to cature an entire web page, not just the visible parts (which is also possible in Firefox, but your desktop manager can also do that).
The keyboard shortcut is
S, or you can right-click on an
empty part of the page and select Take screenshot. You can also add a button
to the toolbar from More Tools -> Customize Toolbar and drag/dropping the
screenshot button into the toolbar.
Firefox add-ons that I find useful:
- Dark reader: Selectively generate nice-looking dark themes for websites.
- uBlock origin: Very effective ad blocker.
- Certificate pinner: Pin which certificate fingerprints for sites and domains. Prevents loading the site before clicking through a warning dialog if the SSL cerificate changes.
- Auto tab discard: Reduce resource consumption from tab hoarding, kills tabs without removing them.
- Privacy redirect: Redirect YouTube/Twitter to Invidous/Nitter etc.
Ubuntu now installs Firefox with
snap, but Mozilla actively maintain a PPA repository
with the latest stable Firefox release (as well as Firefox ESR and Thunderbird).
Start by removing the snap version that Ubuntu installs:
$ sudo snap remove firefox
$ sudo systemctl stop var-snap-firefox-common-host.mount
$ sudo systemctl disable var-snap-firefox-common-host.mount
Ubuntu has a packages named
firefox, which is a meta package for
snap-installed Firefox, which has to be removed:
$ sudo apt-get purge firefox
Then add the PPA from Mozilla:
$ sudo add-apt-repository ppa:mozillateam/ppa
Ubuntu will still prefer its package that installs
snap, so create
to prioritize the PPA over the Ubuntu repos for
Pin: release o=LP-PPA-mozillateam
Pin: release o=Ubuntu
After updating the cache,
apt should prefer the Mozilla PPA package:
$ sudo apt update
$ apt-cache policy firefox
500 http://de.archive.ubuntu.com/ubuntu lunar/main amd64 Packages
500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu lunar/main amd64 Packages
Then install the
$ sudo apt install firefox
