I've lost my toolbar on my acer aspire one netbook

The Acer Aspire One is a netbook, not a laptop.
A netbook is a smaller, scaled-down version of a laptop. It does not have the memory capacity or graphics of a regular laptop.
It also lacks a CD drive, which means you cannot restore the Acer Aspire One with restore discs. Instead, the netbook has a built-in factory restore feature.
You can reset the Acer Aspire One to factory settings just using your keyboard.
Only restore your netbook to factory settings if you cannot fix the problem any other way.
Save any files or folders on your Acer Aspire One with flash drives.
Drag and drop files onto the icon of your flash drive.
Go to Start > Restart to reboot your netbook.

Hold down Alt and F10 when you see the Acer logo on the screen.
The recovery menu will load.
Hit Enter and then Next to see your recovery options.
Choose Factory Restore to set your netbook back to factory settings.
Follow the instructions on the screen.
Choose your time zone and language when the customization menu appears.
Reboot the netbook when you are prompted.
Restore your saved files from the flash drive.

When a vital file becomes corrupted, it might be necessary to restore a computer to its original factory settings.
This process also cleans up the hard drive and removes old programs that can make a computer slow and unresponsive.
But, because restoration wipes away all files you have installed or created, it should be a last-ditch effort in trying to repair a computer.
If you have reached this point with your Acer laptop or desktop, the manufacturer provides a utility to restore the factory settings.

Open the Windows Start menu by clicking on the icon in the lower left corner of your desktop.
Click All Programs, then the Acer folder.

Select Acer eRecovery Management to open the utility.
If a Windows prompt asks for permission to run the program, click Yes.

Click the Restore button in the pane on the left side of the program window.
Click Completely Restore System to Factory Defaults.
Select the Yes option in the dialog box that asks you to confirm the action, and click Start.
Click OK in the second confirmation dialog box to restart the computer.
Click Next in the warning window that appears after the computer reboots.
This confirms that you realize restoring the computer deletes any data stored on your hard drive.

Click Next again in the Restore Destination window, and click OK in the popup that gives you one last warning about deleting your data.
The restoration process will begin.

Click OK when the utility lets you know that the restoration is complete.
The computer will restart, and Windows will finish the recovery process.

• Download driver and software updates directly from Acer's website (see Resources). Save the files to a folder, and then run the setup program to install the software.
  

• Download and install a new software driver for your laptop's on-board audio controller. Many audio controllers in Acer Aspire laptops use the AC97 Audio Codec driver. Go to the Realtek website and click on the "Downloads" tab to see available software (see Resources).
  

• Adjust the sound using the Master Volume setting. Right-click on the audio icon on the toolbar and select "Open Volume Control." Use the Master Volume and Wave input settings to adjust the volume of the audio that is being heard.
  

• Use a software program such as the Realtek Sound Effect Manager to control and adjust the laptop's audio settings. There should be an icon on the desktop or toolbar, but you can also find the program in the Control Panel as well. The program contains an equalizer with presets to choose from as well as mixer and audio I/O options.

Hello,
I do not know why the viewing area decreases in size: I suspect that you may have too many toolbars. Remove the ones you do not need. In IE you right click on a tool bar and deselect ( If there is a check mark near a tool bar, click and the check mark will disappear)

Also you can use the full screen by Pressing F11 in you browser. You exit the full screen by pressing F11 again.
I believe this last option is your best bet short of customizing more fully your browser.

Hope it helps.

Hope it
