How to Run OSCAR in Browser Tabs


OSCAR by default is designed to open as a series of pop-up browser windows on your desktop. For example if you click to open a given E-Chart from the main appointment screen, the new E-Chart will load into a new independent resized pop-up window. The same occurs with adding new appointments, adding prescriptions, E-forms etc.. Every time you open a new part of OSCAR, you get a new window to look at.

Some users may find the multitude of independent open windows on their desktop a little busy, not to mention clumsy to navigate, and instead prefer to look at elegantly organized tabs in a single browser window, such as in the example below:

Running OSCAR in tabs definitely makes for a more streamlined and cohesive EMR user interface. With much of the constant window switching, scrolling and resizing eliminated, you can get your work done more efficiently with less mousing. Navigating between open tabs is a breeze with CTRL+Tab (cycle through tabs forwards) and CTRL+SHIFT+Tab (cycle through tabs backwards). You can easily close an individual tab with CTRL+W.

OSCAR19 Build 19~1656 Onwards

OSCAR19 build 19~1656 and onwards includes built-in settings for making OSCAR run in tabs. setting open_in_tabs as follows:

## Set OSCAR to open in tabs
## Set to optional and each user gets the option to activate OSCAR opening in tabs via preferences
## Set it to true and all users are forced to open in tabs
## false and all users are forced to open in popups

For Older OSCAR Versions

Older OSCAR builds did not include tabs functionality so you need to set your browser to run in tabs the manual way:

Google Chrome/Chromium

Unfortunately at this time Chrome/Chromium do not have an option built-in that allows you to force pop-up windows to open as tabs within the browser so you have to install a third party extension. I use this extension which works however it opens the window in the right-most tab of the current window, so some may find this inconvenient. Firefox does a better job of opening pop-ups in tabs because the tab opens immediately to the right of the parent tab which initiated the pop-up.

I use this extension however use it at your own risk.

If you ever want to return to windowed mode, simply remove the extension.

For Firefox

In order to force pop-ups to open in a new tab:

  1. Enter about:config into the Firefox address bar and confirm the warning message in case it shows up

3. Search for the preference named

4. Double-click it and change its value to 0

If you ever want to return to windowed mode, reverse the above process (change the parameter back to 1). If you find that your still getting tabs instead of new windows opening, then go to “about:config” (type that into your address bar), click past the warning, filter for “” and change the parameter back to 2. You can read more about what that means here.

If all else fails, you can reset your Firefox installation to factory defaults by following these instructions.
