Delete about:config Entries in Firefox

http://www.ghacks.net

I love Firefox because I can pretty much customize it anyway I like to suit my tastes. Besides the add-ons and themes available, Firefox even allows you to change how your browser functions. The key to this is the ‘about:config’ command that you type in the address bar.

With Firefox 2, I use about:config to plug many of Firefox’s notorious memory leaks. The tips I used worked great and I never had any problems with my Firefox. A little while ago though someone posted an interesting question on Lifehacker that I hadn’t really thought about. What if you want to delete an about:config entry?

This is quite a practical question. Let’s say I misspell an entry as I’m typing it in. Obviously, I don’t want to keep these useless entries in my browser so I would get rid of them. The good part is that there’s a very simple way to delete redundant entries without causing any chaos with your browser.

To delete an entry, just right-click it and select Reset. Then, restart Firefox. If the value you chose was originally part of the browser, it will go back to its default value. If the value was added by you, it will be deleted.

I tried out this trick on my own version of Firefox with a few deliberately mistyped entries. It worked fine for me. This is a handy trick to know in case you ever make some unwanted adjustments to Firefox. What do you think of this tip? Do you know of any other way to delete about:config entries in Firefox? Let me know in the comments.

Change Firefox 3 Full Screen Mode Created 23 weeks 3 days ago: I’m normally not using the full screen mode in Firefox because I have a large enough Samsung LCD monitor that displays most websites just fine. Lifehacker discovered that Firefox 3 changed the display of the full screen mode. If you remember Firefox 2 still displayed the tab bar and location bar in full screen mode. Firefox 3 changes this behavior and hides everything.
Watch the Olympics with TVTonic Created 22 weeks 19 hours ago: It’s Olympic year and this time we’re heading to Beijing to watch the best athletes in the world battle it out for glory. If you’re lucky enough to actually be going to Beijing for the Olympics, then you’re sure to enjoy yourself. However, if you’re like me, you have to make do with trying to watch it online.
Change the number of results in the Firefox 3 location bar Created 23 weeks 6 days ago: The default number of results that is shown when a user types in a phrase in the Firefox 3 location bar is 12 which might seem a bit like an overkill to many users. It’s actually very easy to change that amount and either reduce it to a more appropriate number or even increase it if you prefer even more recommendations.
What Would You do with a 1.5 Terabyte Hard Drive? Created 20 weeks 4 days ago: When I got my first computer, my hard drive was all of 2.1 Gigabytes. At that time, it was a huge amount and I didn’t think I’d ever run out of disk space. Fast forward to 2008 and my current configuration includes two hard drives, one of which can hold 250 GB.
Change The Number Of Tabs That Firefox Can Undo Created 21 weeks 14 hours ago: It never happened to me that I wanted to restore more than two tabs in Firefox and even that happened only once since the feature has been introduced to the browser. A right-click on a tab opens a menu that has an option to undo the last closing of a tab in Firefox.
Visualize blue https sites in Firefox 3 in a better way Created 23 weeks 5 days ago: Firefox 3 introduced a new coloring scheme and design for secure websites. You might remember that Firefox 2 displayed a yellow url bar when the user was accessing a https site. This changed drastically in Firefox 3 which is now displaying blue, yellow and green colors in the favicon area on the left side of the url.
Change the Session Store Interval in Firefox Created 21 weeks 1 day ago: Firefox is by default saving the active session every ten seconds. This is handy if the browser crashes to avoid data loss. I was more than once happy that Firefox provided the session restore functionality to avoid loosing part of the article that I had written during that session. Some users might need to change the interval that is used to save the active session either because they want to make sure that the active sessions is stored more often to reduce the data loss further or to extend the interval to free up some resources that are used by this feature.
Change Single- and Middle-Click behavior in the Firefox location bar Created 21 weeks 3 days ago: A left-click in the location bar of Firefox 3 will select the complete URL instead of just moving the cursor to that position. This makes it complicated to select only part of the url. If you do not like that feature and prefer the old behavior I have a nice alternative for you.
A left-click puts the cursor at that position without selecting the full URL while a double-click would select the full URL instead. This can be achieved by changing two parameters in the Firefox configuration.
Properly Reset Firefox Download Actions Created 38 weeks 15 hours ago: When you click on a file Firefox determines if there is a plugin that can handle the file type or if there is a so called download action defined. Download actions are user defined actions that come into effect when the box “Do this automatically for files like this from now on” is checked in Firefox during a file download.
