Vivaldi Web Browser
is a free web browser built on the Chromium
code base (which is the same code base for the Chrome browser). CLASSE-IT
has chosen to support Vivaldi because of its focus on privacy and its stable release schedule. Also, Vivaldi's rendering engine is widely compatibile with modern websites.
Tips & Tricks
Vivaldi default bookmarks
Vivaldi ships with a complete list of example bookmarks. If you want to clear them out before adding your own bookmarks do the following:
- Go to the "Tools" Menu and select "Bookmarks" from the drop down. This will open the Bookmark management page.
- Within the "Bookmarks" Folder, Select the top bookmark entry.
- Shift + click on the bottom bookmark entry (do not select the "Trash" entry).
- Press Delete on your keyboard.
Importing Firefox Bookmarks
For help on importing bookmarks from other web browsers, please see the importing and exporting bookmarks

Some websites (most notably CULearn) require pop-up windows to be enabled to function properly. You can allow pop-ups by following these 4 steps:
- While visiting the site that needs pop-ups, click on the "lock icon" next to the URL.
- Then click on "Site Settings".
- Under "Permissions" look down for "Pop-ups and redirects".
- Use the drop-down menu to select "Allow".
How to use the computer’s default PDF viewer
- Go to the "Tools" Menu (either from the Vivaldi menu, or the top menu bar depending on your configuration).

By default, Vivaldi users hardware acceleration where available. We've found that in some cases this causes vivaldi to hang on cesrtain sites (for example, when viewing PTZ cameras). To disable hardware accleration:
- start Vivaldi, and go to Tools -> Settings
- search for "Hardware" and look for "Use Hardware Acceleration when available”.
- Uncheck that box
- restart Vivaldi
Go to Start
Menu -> Vivaldi
, or Double-click
the Vivaldi icon on your Desktop

Multiple Login Prompts
If you’re using a personal windows computer from home, you may find that you need to login repeatedly when accessing CLASSE web services. To work around this, you’ll need to:
- become an admin
- create an
[HKEY_LOCAL_MACHINE\Software\Policies\Vivaldi] registry key, that contains the following String value:
AuthSchemes = basic,digest,ntlm
This is automatically set on all CLASSE-managed Windows laptops.
A similar workaround should exist for all Chromium-based browsers. Please email firstname.lastname@example.org
with problems or questions.
Go to Applcations
menu -> Internet
at the command line.
From the command line, use
, to use (or create if it doesn't already exist) a profile named "test".
By default, typing "vivaldi" on a CLASSE linux box will start vivaldi using the CLASSE CachingProxy
server for additional security (or to reach offsite from a private subnet).
If you're creating your own vivaldi script or running on a non-CLASSE managed computer, you can launch vivaldi and use our CachingProxy
server by typing on a command line:
By default, typing "vivaldi" on a CLASSE linux box will start vivaldi with the cache size limited to 24MB. Additionally, we recommend making sure ~/.cache is a symlink to /cdat/tem//.cache. This can be done as follows (replacing "" with your CLASSE username:
If you're creating your own vivaldi script or running on a non-CLASSE managed computer, you can launch vivaldi and limit the cache size by typing on a command line:
- logout of any desktops
- ssh lnx201.classe.cornell.edu
- mv .cache /cdat/tem//
- ln -s /cdat/tem//.cache .
