Hi,

Sorry to hear that the websites don't work as expected. In order to troubleshoot the issue, please follow the steps below for each of them:

  1. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield Fx89ShieldIcon icon at the left of the address bar.
    • If ETP is enabled, try disabling it.
  2. If the problem is not fixed, try clearing Firefox cache.
  3. If it does not help, also try clearing cookies and data for the website you experience troubles with (warning: you will be logged out on this website).
  4. If it also does not help, try running Firefox in Troubleshoot Mode.

Did it help? Looking forward to your update!

Popup says "FAIL_SYS_ILLEGAL_ACCESS" when wanting to reply to seller messages in AliExpress and disappears too quick for me to screenshot it. There are other AliExpress problems also.

That all happened after computer restarting and updating. Was okay before the computer doing that.

ETP disabled didn't change anything.

Error message AliExpress

Other browsers don't cause the problems I have with Mozilla Firefox.

Messages yet to be replied to for a valid solution.

None of the problems solved.

Hi there,

Have you tried all the steps above?

Deleted.
