By default, Internet Explorer displays a warning box when it encounters script errors, which are often helpful to developers but of limited use to regular users. Disable script error messages in Internet Explorer by opening the cog menu and clicking Internet Options. Open the Advanced tab and tick the check boxes next to Disable Script Debugging (Internet Explorer) and Disable Script Debugging (Other). Untick the box next to Display a notification about every script error and click OK to save your settings.
Scan Your Computer for Malware
To get rid of malware on your computer, run a full system scan using Windows Defender, an anti-malware application built into Windows. Alternatively, consider installing a free anti-virus program such as 360 Total Security, Avast Free or AVG AntiVirus Free 2015.
Disable Add-ons and Extensions
Press Ctrl+Shift+N and visit the Web page that previously displayed an error or failed to load. If the Google-owned Web page displays properly in incognito mode, close the incognito window and disable your add-ons and extensions one by one to find the extension responsible for the script errors.
Open the Chrome menu and click Settings.
Select Extensions from the sidebar and untick the Enabled check box next to the extension you wish to disable. After disabling an extension, visit the Google page in normal mode and check whether it displays properly.
Launch Firefox in Safe Mode -- a mode where all extensions are disabled -- and visit the page that previously froze or displayed a script error. Open the Firefox menu, click the Help icon and select Restart With Add-ons Disabled. If Firefox properly loaded the page in Safe Mode, launch the browser in normal mode and disable its add-ons one by one until you find the one that causes script errors.
Open the Firefox menu and click Add-ons.
Select Extensions from the sidebar and click Disable next to the name of the extension.
Disable plugins by clicking the Plugins icon in the sidebar and selecting Never Activate from the drop-down menu next to the name of the plugin.
Microsoft Internet Explorer
Launch Internet Explorer with all add-ons disabled by opening your Start Screen, typing cmd in the search field and selecting Command Prompt from the list of results. Enter "C:\Program Files\Internet Explorer\iexplore.exe" -extoff in the Command Prompt window and press Return to launch Internet Explorer without add-ons.
While using the Command Prompt is the only way to launch Internet Explorer with no add-ons under Windows 8, Windows 7 users can start the program by opening the Start Menu, typing Internet Explorer in the search box and selecting Internet Explorer (No Add-ons) from the list of results.
If you can load the Google page with add-ons disabled, launch Internet Explorer in normal mode and disable its add-ons one by one to identify which one is preventing your browser from correctly running the page's scripts.
Open the Tools menu and select Manage Add-ons.
Select the name of the add-on you wish to disable and click the Disable button.
Upgrade Your Computer
Older or slower computers may lack the processing power a browser needs to properly run scripts. Consider upgrading your system to prevent tab freezes when loading script-intensive pages.
Alternatively, shutting down unneeded applications before browsing and limiting the number of tabs opened at the same time may help your browser load pages faster.
