Recently started having odd behavior from FF, crash sometimes when opening a video in PIP, crash every single time I open a new private window with hotkey.

Had some freezing as well as right-click menus not showing options, those went away by enabling HW acceleration.

Submitted crashlogs and found a bugzilla link refrenced. https://bugzilla.mozilla.org/show_bug.cgi?id=2000475

Can I downgrade to 144.0 without losing profiles/settings/passwords and history? Do I just download the 144.0 installer or is there a different process for downgrading? (I am assuming this could help exclusively based on the bugzilla refrence, it might not)

Not sure what else to do, FF is still freezing after watching videos for a few minutes, I am not even sure if this is strictly a FF issue or a Win 11 issue.

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

  1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) Crash Reports will appear, similar to the one shown below.
  2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Took my time to collect a few more logs. Originally it was happening consistently while windows was running a scan in the background, but as it turns out it happens regularly anyway.

Some WindowsOS library is crashing here. Can you try to switch widget.windows.windowsappsdk.enabled to false in about:config + restart the browser, for testing?

Hi, I made the change some time ago and continued using the browser. I noticed that memory usage increased significantly (around 10GB more usage from what used to be the maximum), I also experienced "desktop window manager" dwm.exe crashing twice.

However the crashing itself stopped, I can open and close FF windows normally.
