 #25130 is a duplicate.

 jllover: I assume this issue shows up due to us enabling sandboxing
 support for Windows with 7.5. Alas, this did not get caught in our testing
 and seems to be only affecting Windows Vista which is not supported
 anymore from Microsoft.

 Not sure if you still can open new tabs but if so, open one and enter
 `about:config` in the URL bar and then you can test whether disabling the
 sandbox solves the issue for you by setting
 `security.sandbox.content.level` to `0`.
