Using Bash scripts in Linux to delete the history, cookies and cache files of Firefox, Google Chrome and Thunderbird

The browsing data stored by Firefox, Google Chrome and Thunderbird can be deleted using the respective application’s GUI. But you can also do that using a Bash script, which could be useful if you want to delete unnecessary/unwanted files before e.g. backing up your home directory, or if you want a quick and easy way to clear-out browsing data. In this post I list the scripts and Desktop Configuration files I have created in Gentoo Linux and in Lubuntu 18.04 to remove browsing data.

In the case of Thunderbird, I am not sure if it is safe to delete Thunderbird’s cache files so my script only deletes cookies. Anyway, that could be added later if it transpires there is no harm in deleting Thunderbird’s cache files.

I am using the following 64-bit versions of the two browsers and e-mail client:

  • Mozilla Firefox 74.0
  • Mozilla Thunderbird 68.5.0 in Gentoo Linux only
  • Google Chrome 80.0.3987.132 in Gentoo Linux
  • Google Chrome 67.0.3396.99 in Lubuntu 18.04

I have not tested my scripts with other versions of Firefox, Chrome and Thunderbird, nor in other installations, so please do check carefully the directory paths and commands in the script against the directory paths in your installation before selecting ‘[D]elete‘ in the running script.

In Lubuntu 18.04 I had to install sqlite3 first:

$ sudo apt install sqlite3

In Gentoo Linux it was already installed:

$ eix -I sqlite

Firefox and Thunderbird

I created the Bash script Firefox_or_Thunderbird_-_Clear_data.sh listed below. The user can select only Firefox or only Thunderbird, or both, and the script enables the user to choose whether to just view the current situation or to delete the data. The script checks if the applications are running and will not do anything if they are. In fact, the script offers the user the option to terminate the applications if they happen to be running. The script is still usable if either Firefox or Thunderbird are not installed. The same script can be used in Gentoo and in Lubuntu 18.04, and I believe it would also work in Ubuntu but have not tested it with that distribution.

#!/bin/bash
#
# If Delete is selected for Firefox, this script deletes the entire history, cookies, site data and cache.
# If Delete is selected for Thunderbird, this script deletes the cookies and leaves the cache intact.

Listed below is the Desktop Configuration file Firefox_or_Thunderbird_-_Clear_data.desktop for KDE in Gentoo Linux that I created in the ~/Desktop/ directory. I downloaded a nice PNG icon from the Web, which I saved as ~/Pictures/Icons/Mozilla.png, although of course the Desktop Configuration file can be modified if the icon file were to be stored elsewhere. Obviously change the username accordingly.

And below is the Desktop Configuration file Google-Chrome_-_Clear_data.desktop for Lubuntu 18.04.

Obviously change the username accordingly.

Update March 23, 2020: For those of you who would prefer a single script that can delete the browsing history, cookies and cache files of Google Chrome and/or Firefox and/or Thunderbird, I have now created the script clear_browser_data.sh shown below with appropriate Desktop Configuration files for Gentoo Linux and Lubuntu 18.04. In addition I have now added the ability to list and delete the history and cache files of Thunderbird, as I have checked that deleting those is not detremental to Thunderbird. Furthermore, this new script finds the directories itself rather than having them partially hard-coded in the script, so I am using the same script in both Gentoo and Lubuntu 18.04. That said, I have not tested the script with other versions of Chrome, Firefox and Thunderbird, nor with other Linux distributions, so do not select [D]elete until you have checked that the directories evaluated by the script match the directories in your installation.

Listed below is the Desktop Configuration file clear_browser_data.desktop for KDE in Gentoo Linux that I created in the ~/Desktop/ directory. I downloaded a nice PNG icon from the Web, which I saved as ~/Pictures/Icons/broom.png, although of course the Desktop Configuration file can be modified if the icon file were to be stored elsewhere. Obviously change the username accordingly.

    Thanks for the comprehensive work 👍 Here at home I switched all our old Macminis, iMacs (white and silver) to lubuntu and we are fast and reliable again. And with your scripts it should be in the future… LG RH
