Is there a way to list the open tabs in Firefox from the command line?

The idea would be to access Firefox data from the 'outside'. You might want to look at Stack Overflow question How can I get list of open tabs in Firefox via a command-line application?.

    Ahhh - the sessionstore.js (JSON) file in your FF profile does seem to contain the appropriate list. Albeit inside a lot of noise. Seems structured enough to parse out though. Thanks for the link.

The format in latest versions is JSON compressed with LZ4 + a magic header (mozLz40\0).

This small python script will print tabs: https://gist.github.com/tmonjalo/33c4402b0d35f1233020bf427b5539fa

  • To use it in Ubuntu, you need to sudo apt install python3-lz4

I recommend using https://github.com/balta2ar/brotab for this purpose:

pip install brotab
brotab install

Install the web extension as well: https://addons.mozilla.org/en-US/firefox/addon/brotab/

Restart Firefox, and you can run brotab commands such as:

brotab list

In Linux, you can do it with this (admittedly long) command:

lz4jsoncat $profile/sessionstore-backups/recovery.jsonlz4 \
| jq -r '.windows[] | .tabs[] | (.index - 1) as $i | .entries[$i] | .title, .url, ""'

This assumes you have set the $profile variable to your current Firefox profile with something like

profile=$HOME/.mozilla/firefox/Your_Profile

It needs the lz4json and jq packages. In Debian or Ubuntu, install them if needed with :

sudo apt install lz4json jq

According to the mozilla site, no. Command Line Options

Although you could write a plugin to write tab names to a text file I guess.

  • Thanks, I think your answer is the "right" one from a supported standpoint. But, hack > nothing.
