Our Customer care agent may request that you record an **HAR file** (stands for HTTP Archive), or a log of network requests, at the moment when that issue is occurring and provide it to them for further investigation. Below are the instructions on how you can generate an HAR file in a few most popular browsers. If your browser isn’t listed, try searching for a guide on generating an HAR file in the web. #### In this article: 1. [Google Chrome](https://learn.fcrmedia.ie/knowledge/generating-an-har-file#chrome) 2. [Mozilla Firefox](https://learn.fcrmedia.ie/knowledge/generating-an-har-file#firefox) 3. [Safari](https://learn.fcrmedia.ie/knowledge/generating-an-har-file#safari) 4. [Microsoft Edge and Internet Explorer 11](https://learn.fcrmedia.ie/knowledge/generating-an-har-file#edge-and-explorer) ### Google Chrome To generate a HAR file in Google Chrome: 1. Open Google Chrome and go to the page where the issue is occurring. 2.
