Thanks for the additional information, it is very strange.
Can you try to follow the instructions in the "Shutdown" part of this documentation: https://profiler.firefox.com/docs/#/./guide-startup-shutdown?id=shutdown
Hopefully you'll get the raw json file on disk, that you can then compress and attach here. You can also send it to me by email using a file service such as https://wormhole.app/ at: julien at mozilla.com.

01:56:04.783 The following profiler information is available via the console:
window.profile - The currently loaded profile window.filteredThread - The current filtered thread window.filteredMarkers - The current filtered and processed markers window.selectedMarker - The selected processed marker in the current thread window.callTree - The call tree of the current filtered thread window.getState - The function that returns the current Redux state. window.selectors - All the selectors that are used to get data from the Redux state. window.dispatch - The function to dispatch a Redux action to change the state. window.actions - All the actions that can be dispatched to change the state. window.experimental - The object that holds flags of all the experimental features. window.togglePseudoLocalization - Enable pseudo localizations by passing "accented" or "bidi" to this function, or disable using no parameters. window.toggleTimelineType - Toggle timeline graph type by passing "cpu-category", "category", or "stack". window.retrieveRawProfileDataFromBrowser - Retrieve the profile attached to the current tab and returns it. Use "await" to call it. window.saveToDisk - Saves to a file the parameter passed to it, with an optional filename parameter. You can use that to save the profile returned by "retrieveRawProfileDataFromBrowser".
The profile format is documented here: https://github.com/firefox-devtools/profiler/blob/main/docs-developer/processed-profile-format.md

Here are some updated instructions if you can still reproduce reliably.
1. go to profiler.firefox.com and update the app by clicking the "apply" button in the notice at the top (if you haven't done that this week yet) 2. reproduce the issue. 3. open the web console in the devtools 4. run this in the WebConsole `saveToDisk(await window.retrieveRawProfileDataFromBrowser()) ` 5. share the file with usThanks
Can you ran this ^ this should have saved a file on your computer. Can you please find it and share it with us? You can use https://wormhole.app/ and send it to my email julien AT mozilla.com. Thanks!
