Browser Settings

Adjusting browser settings to cache pages in your Web browser enables you to quickly access the pages you visit frequently. These adjustments make pages load faster and reduce the possibility of JavaScript error messages. NetSuite recommends that you adjust browser settings in order to maximize your NetSuite performance.

Internet Explorer

1. In your browser header, go to Tools > Internet Options.

2. On the General tab, in the Temporary Internet Files or Browsing history section, click Settings.

  • In the Check for newer versions of stored pages section, select Automatically.
  • In the Temporary Internet files folder section, set Amount of disk space to use: to 50MB.
  • Click OK.

3. Click the Security tab.

  • Click the Trusted Sites icon, and then click the Sites button.
  • Enter the address http://* and click Add.
  • Click OK.

4. Click the Privacy tab. The Settings section should not require any changes. We recommend setting the slider to Medium or Medium High. Setting privacy to High will require that you manually enter https://,, and as allowed sites by clicking the Sites button.

5. In the Pop-up Blocker section, if the Block pop-ups box is checked, click Settings.

  • Enter the address, and click Add.
  • Click Close.

6. Click the Advanced tab.

  • Under the HTTP 1.1 section ensure that both the Use HTTP 1.1 and Use HTTP 1.1 through proxy connections boxes are checked. These settings guarantee that all content on a page is delivered as rapidly as possible.
  • Under the Security section, clear the box for Do not save encrypted pages to disk. If you must ensure that none of your cached content is ever accessible, check the Empty Temporary Internet Files folder when browser is closed box instead. This will cause NetSuite to perform more slowly upon login, but all subsequent pages will perform well.
7. Click Apply, and then click OK.


1. In the browser heading, go to Tools > Options.

2. Click the Advanced icon.

3. In the Cache section, edit your settings to “Use up to: 50 MB of disk space for the cache.” Close all open browser windows after changing your settings, and then open a new browser window before logging back in to your NetSuite account. If you encounter JavaScript errors after making these changes, hold down the CTRL key on your keyboard while clicking the Refresh button in your browser. This forces an update of your cached JavaScript files. If this change does not result in performance improvements, you can check to see whether the caching of secure pages currently is enabled. Note that client performance can be adversely impacted because of the default setting in FireFox not to cache secure pages.

To enable caching in FireFox for secure pages (href="">

  • Open a FireFox browser window.
  • In the address bar, type the text below, and then click Go: about:config.
  • Scroll down to the preference browser.cache.disk_cache_ssl.
  • Right-click on the preference line and select Toggle, to set the Value to “true.” FireFox now caches secure pages, including all pages. By caching these pages, FireFox can load pages more quickly.

Clearing Browser Cache

Sometimes you may experience temporary performance issues due to the contents of your Browser cache (temporary internet files). If you have never cleared cache before, it may take 5 minutes or longer to clear your cache files the first time. Subsequent attempts to clear cache should take less than 1 minute if done on a regular basis. Because this process takes a very short amount of time, you may want to clear cache as needed whenever you notice slow performance or multiple Java script errors (Errors on Page) while working in NetSuite.
