The compatibility matrix for multiple versions of Liferay Digital Experience Platform (DXP) lists Edge (latest) as tested and compatible with Liferay DXP. However, Microsoft has two distributions of its Edge browser: EdgeHTML (also called Edge Legacy) and Edge Chromium.
Edge Chromium
Liferay DXP 7.3 and Above
Edge Chromium is the Edge browser tested as compatible with Liferay DXP 7.3 and above.
Liferay DXP 7.2 and Below
Liferay will default to ensuring that Edge Chromium is tested as compatible with Liferay DXP.
EdgeHTML or Edge Legacy
Liferay DXP 7.3 and Above
EdgeHTML or Edge Legacy is not tested as compatible with Liferay DXP 7.3 and above. The resolution for issues reported while using Liferay DXP 7.3 and above with EdgeHTML will be to use Edge Chromium.
Liferay DXP 7.2 and Below
Liferay will default to ensuring that Edge Chromium is tested as compatible with Liferay DXP. However, we understand adopting a new enterprise-wide browser takes time, planning, and user training.
Liferay will maintain this level of effort until March 9, 2021. March 9, 2021 was the end of life date for Edge Legacy also called EdgeHTML. Lifeary only tests compatibility with products in active life. Since Edge Legacy has reached end of life only Edge Chromium will be tested for compatibility.
Until September 10, 2021 Liferay will seek to resolve issues reported while using Liferay DXP 7.2 and below with EdgeHTML using a commercially reasonable effort and determined on a case-by-case basis. If the level of effort to resolve the issue is not commercially reasonable for Liferay Subscription Services then Liferay would seek to resolve the issue in Edge Chromium.
