Crash Data
Crash in TF_Notify with epclient64.dll from Citrix Workspace by Citrix Systems (C:\Program Files (x86)\Citrix\ICA Client\epclient64.dll).
Example crash report: here
This is the same crashing instruction as bug 1777960 (ZoneAlarm Anti-Keylogger), and also from Windows 11 22H2 users. Starting with Windows 11 22H2, Microsoft has made internal changes in msctf.dll. The TF_Notify function, also known as CtfImmNotify from imm32.dll, uses a new convention for its third argument. These changes would be incompatible with current versions of Citrix Workspace, resulting in crashes in the Firefox main process. This is presumably linked to their anti-keylogger feature.
This is should be very impacting for the affected users as it presumably makes they crash as soon as they type. I will forward the information we have to Citrix Systems.

We managed to reach the App Protection team and, even though they are unable to reproduce the issue, they acknowledged the change in msctf.dll and are therefore working on a fix based on the information we forwarded. It will take several months for the fix to reach users because of the slow release cycle of the product.

Just checking in on this - the latest epclient64.dll in this signature bucket is 23.8.0.13, and this is also the latest version we see across all third-party-modules pings, so it doesn't appear that this is fixed yet.
(note that the crash volume for the TF_Notify signature has gone down significantly, but this is because bug 1777960 is bucketed together with this, and that has been fixed)

Since the crash volume is low (less than 15 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

According to the vendor this issue should now be fixed in the latest versions of Citrix products. If the fix does not work, new crashes should have a new ctxapclient64.dll DLL (or ctxapclient32.dll), in version 23.11.0.6.
