Firefox search in new tab

Posted on by
Reply

This new tab behavior doesn’t require changing the address bar search feature, it has its own preference. The hardest part is learning its name:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren’t fully supported and aren’t guaranteed to continue working in the future. Since I use this one myself, I feel comfortable mentioning it, even if it does turn out to be temporary relief only.

(2) In the search box in the page, type or paste handoff and pause while the list is filtered

(3) Double-click the browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar preference to switch the value from true to false

Success?

sleep with Nvidia

I had problems returning from sleep with Nvidia as well. After googling for quite a while, I found a solution that worked for me. I created a file called “nvidia-power-mgmt.conf” in etc/modprob.d with this line in it:

options nvidia NVreg_PreserveVideoMemoryAllocations=1

And after a reboot, sleep/resume seems to be working fine now.

Firefox Recovering important data from an old profile

Posted on by

A Firefox profile stores all of your important data, such as your bookmarks, history, cookies, and passwords. This article explains how to copy the files to a new profile, lists important files in the profile and describes what information is stored in these files.

Note: Because your preferences and extensions often cause problems, this article does not explain how to copy these between profiles. If you follow the steps in this article, you will have to reinstall your extensions and reconfigure your Firefox preferences.

Table of Contents

Back up your current profile

Before starting it is recommended that you make a complete backup of your existing Firefox profile in case something goes wrong. Please read the Back up and restore information in Firefox profiles article for instructions.

Create a new Firefox profile

Note: This step is not needed if you already have a new Firefox profile, for example, a profile you previously created or a dedicated profile for another Firefox installation.For information on how to create a brand new Firefox profile, please read the Profile Manager – Create, remove or switch Firefox profiles article.

Copying files between profile folders

Important: Firefox must be closed down while copying files between profile folders. Also, Step 1 refers to your “old” profile folder – the profile containing data you want to copy to a new profile. If you can’t open a profile from within Firefox, see Finding your profile without opening Firefox.

  1. Open your profile folder:
    • Click the menu button Fx89menuButton, click Help and select Troubleshooting InformationMore Troubleshooting Information.From the Help menu, select Troubleshooting InformationMore Troubleshooting Information. The Troubleshooting Information tab will open.
    • Under the Application Basics section next to Profile FolderDirectory, click Open FolderShow in FinderOpen Directory. A window will open that contains your profile folder.Your profile folder will open.
    Note: If you are unable to open or use Firefox, follow the instructions in Finding your profile without opening Firefox.
  2. Click the Firefox menu Fx89menuButton and select Exit.Click the Firefox menu at the top of the screen and select Quit Firefox.Click the Firefox menu Fx89menuButton and select Quit.
  3. Right-clickHold down the control key while you click on a file you want to copy and choose Copy.
  4. Open the new Firefox profile folder as explained in step 1, above.
  5. Right-clickHold down the control key while you click inside the profile folder and choose Paste Item.

Repeat steps 3-5 for each file you wish to transfer over to your new profile folder.

While copying your personal data from an old Firefox profile to a new Firefox profile, it is possible that you could copy over the file that is causing the problem you are trying to get rid of! The more files you copy over, the greater the chance of this happening. It is therefore recommended that:

  • You copy over only the minimal amount of files that contain your most important data that you simply can’t live without.
  • You copy over a few files at a time, and then check that the problem you are trying to get rid of hasn’t returned.

Note: By default, Windows hides the AppData folder where Firefox stores your profile. To set Windows to show hidden files and folders, see Show hidden files – Windows Help.
