Firefox Dev tools: How to persist calls in network analysis


Since Firebug is outdated with a recent update of Firefox I'm trying to work with the Firefox dev tools. As far as I read these are supposed to replace Firebug.

However there is one option I used frequently in Firebug and haven't found yet in the Dev tools: The persist option in the network analysis. The persist option in Firebug

Since I work on a project that uses AJAX Calls to send data and then redirect to another page, I need to persist the calls to analyze them after the redirect. Otherwise the time is far to short to have a look at the data that was send with this call. (This project is for work so this architecture is nothing I could change).

Is there a way to persist the network calls in the Firefox Dev tools?

(I use Firefox 56.0.1 by the way)


Solution

  • Open the Settings for the Developer Tools:

    Developer Tools Settings Button

    Then select "Enable persistent logs" under "Common Preferences."

    Starting from Firefox 57.0 the option got moved from the Settings to the Network panel:

    "Persist logs" option in Network Monitor
