(In reply to Oriol Brufau [:Oriol] from comment #0) > I can reproduce the problem at least since 2021-06-09 8508c35e49793fbe402ad2a706a57fabd1c2b0c4. Earlier builds instacrash any tab before I can try the testcase. If you're on linux, this is likely due to the fact that there's a range of Nightlies whose sandboxing code doesn't play well with current OS libraries (or something to that effect). Assuming you're running into this instacrash on mozregression, the workaround is to invoke mozregression like so, to disable the sandbox: ``` mozregression --pref "security.sandbox.content.level:0" ```
