In
%TRIDION_HOME%\Web\WebUI\WebRoot\Configuration, open the file
system.config, update the line with <browser name="Google Chrome ...>
For example:
<browser name="Google Chrome 50+" regExp="Chrome/([5-9]\d+|\d\d\d+)"/>
For versions of Firefox 100 or above
In %TRIDION_HOME%\Web\WebUI\WebRoot\Configuration, open the file system.config, update the line with <browser name="Mozilla... .
For example:
<browser name="Mozilla Firefox 47+" regExp="Firefox/((4[7-9]|[5-9]|[1-9]\d)\d+)" />
Note: For Microsoft Edge
The name attribute is only to indicate to developers/implementers what browser the regExp is meant to match against, it's not used in the check itself. The code will iterate over (test against) all the regExp values.
If using the Edge browser console and check the window.navigator.userAgent, a similar string to the following will be seen:
userAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.134 Safari/537.36 Edg/103.0.1264.71"
So by updating the Chrome regExp entry the Edge browser will also be handled by passing the check of the same regExp.
