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.

Ensure "Ctrl+Tab cycles through tabs in recently used order" option is unchecked.

Tab Suspender

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

This feature goes by many names, including:

Tab Sleep, Tab Snooze, Tab Freeze, Tab Suspend, Tab Discard or Tab Hibernation.


May be a similar feature built in to Firefox

Ad Blockers

Instead of adblock, I have been exploring a more general filter / tracking blocker:

When creating documentation, it is useful to be able to copy all open tabs in a window.
Copy All Tabs :: Add-ons for Firefox

have used this in the past as well:
and this may have similar functionality


New Tab

This is optional.

I love pocket.

Tabliss is a clean minimal alternative.

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.


Read up on 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, can try manually editing: ~/.mozilla/firefox/profiles.ini

(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/


Colorway themes can be helpful for distinguishing one Firefox context from another, especially if they get spread across multiple workspaces.

Menu -> Add-ons and Themes

Not configured in "Settings".

Chrome / Chromium:

For non-linux machines, go with Chrome:


sudo apt-get install chromium-browser


Change "On startup" to:

"Continue where you left off"

to restore previous session.


The Great Suspender!

Suspend Tabs after a certain period of inactivity This is great! Saves so much memory and resources! Wish I could find something equivalent that works for Firefox...
