The other day, by chance, I came across the built in status bar quota usage display. I had accidentally set the storage limit on one of my mailboxes to ‘null’. In turn Thunderbird presented me with a red bar warning me that I was way over my quota.
Today, I decided I wanted the usage to display on my IMAP accounts at all times. This is what needs to be done:
- In Thunderbird go to Tools -> Options…
- Select the ‘Advanced‘ panel, under the ‘General‘ tab, click the ‘Config Editor…‘ button.
- Find the following setting: ’mail.quota.mainwindow_threshold.show‘ and set it’s value to ‘0‘
Thunderbird needs to restart for this setting to take effect.
Additionally, there are options for setting the Warning and Critical thresholds. These cause the precentage bar to change to yellow and red.
mail.quota.mainwindow_threshold.warning
mail.quota.mainwindow_threshold.critical
