I have one more Firefox 3.6 about:config tip up my sleeve.  By toggling one setting, you can go from having a drop down list of tabs to a thumb-nailed view of each tab that is open.

Here is how you too can enable this secret Firefox 3.6 feature.

How to Enable the Tab Preview Menu Button

• Type about:config in the address bar. Then, if needed click the “I’ll be careful, I promise!” button.
• Next, in the filter box – type in:
  • browser.allTabs.previews
• Right-click that about:config entry, and select “Toggle”

This will change it from false, to true.  You could take the same steps to disable it too.  Now when you click that icon with the four tiny squares, you will get a visually prettier way to check out all your tabs.

Also once this has been enabled, you can use the keyboard combination:

Shift + Ctrl + Tab

To get the same tab previews, just without the button clicking.

New to Firefox 3.6, when you are on a page, and you want to open a link in a new tab – rather than opening the link in the far right of the tab bar, Firefox will now open the link right next to the tab you are in.  Now, while this might be convenient for some, it is a feature I don’t really need.  So here is how you can disable the new “Insert Related Tab After Current” tweak in Firefox 3.6.

Make New Tab Pages Open in the Far Right of the Tab Bar

• Type about:config in the address bar. Then, if needed click the “I’ll be careful, I promise!” button.
• Next, in the filter box – type in:
  • tabs.insertRelatedAfterCurrent
• Right-click that about:config entry, and select “Toggle”

This will convert Firefox back to loading opening a new tab from a web page on the far right of the tab bar, rather than right next to the tab you opened it from.

To switch back, follow these same steps and toggle the “false” back to “true”.

This should help those of you out there who do not like this new feature to Firefox 3.6, or are just not ready to switch how you open a page in a new tab just yet.

With Firefox 3.6’s release, we can all do a quick about:config tweak that will enable the prettier tab switching.  By default, when you hit the keyboard keys Ctrl + Tab you just rotate through your tabs.  By making some quick adjustments though, you can pull up the new tab switcher that you see in the picture above.

How to Enable Firefox’s Secret Visual Tab Switcher

• Type about:config in the address bar. Then, if needed click the “I’ll be careful, I promise!” button.
• Next, in the filter box – type in:
  • browser.ctrlTab.previews
• Right-click that about:config entry, and select “Toggle”

Now, when you hit the keyboard combination of Ctrl + Tab you will get the new visual tab previews, rather than just scroll through the tabs one by one.  If you want to switch back, just follow the same steps to toggle it from true, back to false.

#5 – Speed up Flash Videos in Firefox

Want to speed up your flash video watching?  By default, Firefox takes a sort of “snapshot” of whatever you are doing every ten seconds.  Why?  It is so that the browser can restore itself, just in case of a crash.  Now you might ask, what does this have to do with flash videos?  Well, the snapshot action is what is causing your ten second delay, at times, with watching flash videos on the Web.

#4 – 10 Popular Themes That Are Firefox 3.5 Ready

Before the tweak (notice the close tab button is on the tab itself)

After the tweak (notice the close tab button has been moved to the far right)

Now what is the secret?  You just need to do a little editing in your about:config page.

1. Type in about:config in the Firefox address bar
2. Tell Firefox you’ll be careful, promise! (unless you already asked Firefox not to be warned about this anymore)
3. In the the filter box you see at the top, type in browser.tabs.closeButtons
4. Right-click it’s entry on the about:config page, and choose “Modify”
5. Change the value from 1 to 3 (you can switch it back the same way if you don’t like it)
6. You are done!  Enjoy your tab closing button in it’s new location!

Hope you enjoyed this quick customization tip, using the powers of the about:config settings and configurations.  If you enjoyed this one, be sure to check out the other about:config tweaks we have covered in the past too.

So what is the solution?  Time to visit our good friend, the about:config…

The quick fix for this problem, at least for my own sake, is to increase the time between each of the saves performed by session restore. By opening about:config in your Firefox address bar, then typing browser.sessionstore.interval in the filter box, you’ll see a value of 10000, which is in milliseconds. (Meaning your session is saved every 10 seconds.) I changed this to 300000, or every 5 minutes, as I don’t have the urgent need for tab restoration. If you feel like being more on the safe side, try increasing it to something a bit lower, say 120000, or every 2 minutes.

I gave it a shot, and it might not be a life changing experiance after doing so, but it does seem to make the videos play faster, especially if you have several Firefox tabs or windows open at the same time.

This extension of Firefox will give you a lot of the “about:config” preferences, in an easy to navigate menu box.  It displays the options, included in the current version, using checkboxes, dropdown lists and textboxes.

If you want to check out all the advanced settings that gui:config makes available to you, Lifehacker has done a nice gallery of each tab you see in the screenshot above.

I would consider this extension well worth trying out, at least.  The add-on, gui:config is a must have for anybody who likes to tweak and customize their browsing experience.  You can find out more about the development at:  http://guiconfig.freedig.org/.

In the address bar, type in about:config, and then hit enter.

At the warning, click the button that says, “I’ll be careful, I promise!”.  Now you are ready to do some configuration changes.  We want to setup a new option though, so right-click anywhere inside of the about:config screen and then go to New > Integer.

For the preference name type in:

browser.bookmarks.livemark_refresh_seconds

Now, for the value, you will need to add your time up by seconds.  For example, if you wanted it to be reloaded every two minutes you would type in 120 (because there are 120 seconds in two minutes).  The smallest number you can put in here is 60 seconds.  If you put in anything lower, Firefox will slap you in the face – and then say, “Oh yeah, you wanted to put in ’60′ right?”.

You can also reload a Live Bookmark manually to by right-clicking it and choosing “Reload Live Bookmark”.  However that isn’t nearly as fun as diving into about:config.

Just type in about:config into your address bar to get started.  Next, into the filter text box, type in layout.spell.  That should bring up the preference name layout.spellcheckDefault. Right-click it, and then select “Modify”.  Change the 1 (default value) to 2 and you should be all set. 

Firefox’s built in spell check will now check all text fields, no matter where or how they are used on the web site in question. 

What if you just want to do a regular Google search? 

There is an easy way to turn your address bar into a Google search box.  You want to type into your address bar about:config.  Next, type into the filter keyword.URL. Once you have found it there, modify the string in there and replace it with:

http://www.google.com/search?btnG=Google+Search&q=

From now on, when you type in a word or phrase into the address bar and hit enter, it will launch a Google search for it rather than giving you Google’s top result for that word or phrase.
