By modifying preferences in about:config you can change different firefox behaviours.
Simply type: about:config in the address bar and press Enter, and you’ll see a list of different firefox settings listed in alphabetical order.
FINDING A SETTING QUICKLY:
- If you know exactly what you are looking for you can narrow down the list, by typing the search term in the Filter: field – or copying and pasting the term (from the list below, these are in bold beside “Go to:”) *make sure there is no space at the end of the text.
To get the full list back again, click the Show All button or just clear the Filter: bar
EDITING A PREFERENCE:
- Double-click on the name or right-click and choose modify and you’ll be prompted for the new value.
- If you double-click on an entry that has a Boolean value, it’ll just switch from true to false or vice versa; double-click again to revert to the original setting.
Not all changes take effect immediately, so if you want to be absolutely certain a given change is in effect, be sure to close and reopen Firefox after making a change.
