The “Post All” feature for the showing sheet will open a window for each of the listing within and take you to the confirmation page of Craigslist. However, we have found that the Firefox browser only allow a maximum of 20 pop ups to be displayed at a time.

If you would like to change your Firefox browser limit of 20 pop ups please follow the guideline bellow.

(Disclaimer – opening multiple tabs or windows can slow or crash your browser. Performance varies greatly base on computer configuration. Use at your own discretion.)

1. In your Firefox address bar type in “about:config”

2. Hit enter and click on the “I’ll be carefull, I promise!” button.

3. Find “dom.popup_maximum”

4. Double click on the number to change the maximum pop ups allowed.

And we are done. You should now be able to open as many pop up windows as the number you just indicated.
