Running multiple browsers with different profiles helps keeps active references in the right place. When the work is finished, just close that browser. Good for keeping memory free.

If you need a browser context for a specific task / job

firefox -p does the trick!

If no relevant profile is available, just create one.

Be sure to set Menu -> Settings -> Restore previous session.

'Auto Tab Discard' does what I'm after. Closest working alternative to 'The Great Suspender'

Profile Management

If you make frequent use of profiles, it can help to create a default profile.

Locate where your profiles are stored:

Available on about:support using the "Open Directory" button in the "Profile Directory" section.


or under snap at


How to backup and restore profiles:

Recommendation is to use built in Firefox Profile manager to create a new profile first, then copy the contents of your default profile in to the newly created directory. That way all of the configurations in the browser are set up correctly.

If you need to update the order, try manually editing:

(make a backup first!)

A template Firefox profile that tracks these notes is available here:

mkdir repos
cd repos/
git clone
cd .mozilla/firefox/
# Create the new profile via Firefox
rm -r hn95wtr8.example/*
cp -r ~/repos/firefox-profile/* hn95wtr8.example/

New Tab

This is optional.

Tabliss is a clean minimal alternative to the default new tab page.

An open source, pluggable New Tab web extension written in TypeScript, React and Redux.

No special permissions required!

killall firefox;
sudo snap refresh;
