Both latest Firefox and Thunderbird fail to open and show crash report just after initialization with macOS Catalina Version 10.15 Beta (19A526h). I can not operate Firefox in Safe Mode because it crashes whenever I try to start it.

Firefox and Thunderbird ? ! ?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thanks Fred. Unfortunately, it is still crashing the same way.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

If you can't get Firefox to open, you will have to do this the hard way.

Hi Fred and thank you very much. Put both the MacBook Pro (late 2016) in Safe Mode and tried to start Thunderbird and Firefox - both still crashed. Tried running both Mozilla programs in Safe Mode - still an immediate crash. I am using macOS Catalina 10.15 beta 5, build (19A526h). Catalina was fine with both Firefox and Thunderbird until this last Beta 5 update. I also tried the Firefox Nightly 8/2/2019 and latest beta of Thunderbird - still immediate crash. I reported this to Apple Developers as well.

Apple responded indicating this is a macOS bug and they'll be fixing it. We don't have a time frame yet.

Bug 1563631 may have similar describe similar issues. However, I didn't have any issues with Firefox or nightlies until I installed macOS 10.15 beta 5 (Build 19A526h). Prior builds worked well with Firefox and Thunderbird, until I installed 19A526h.
