Internet Explorer tabs freezing or open slowly

The performance of Internet Explorer has improved over the years especially in version 8 onwards. It now opens quickly, is secure, and renders webpages very well. But sometimes you may find that its new tabs freeze while opening or are slow to open. If you are facing this problem, this post may help you.

Internet Explorer tabs freezing or open slowly

If you find that your tabs open slowly, try some of these troubleshooting steps:

First and foremost, check if you have a bad add-on. Run Internet Explorer 9 in No Add-ons mode and see if makes a difference.

If it does, then its probably one of your add-ons creating a problem.

Through Internet Options > Manage Add-ons, you can enable/disable each add-on to identify which, if any, add-on is creating problems. You may also want to monitor your browser add-ons and disable those which may be hitting performance.

Do you have a Java Plug-In’s SSV Helper 2 plugin installed? It is know to cause such delays. Disable it and see if it helps.

Do you use Spybot? Or have you added many websites to the Restricted Zone? Remove all sites added by Spybot’s Immunize. To do so, open regedit > Navigate to the following key:

HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Internet Settings \ZoneMap

Delete the following sub-folders:

Domains, EscDomains, Ranges

Next, go to this key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\P3P

Delete the sub-folder


Do the same for this key:


Also try the following, if you are still perplexed.

From an elevated Command Prompt window, Run the following command:

regsvr32 actxprxy.dll

This re-registers the ActiveX Interface Marshaling Library.

As a last option you may want to Reset Internet Explorer.

Hope something helps!
