Hi
I tried to replicate the issue using Linux Ubuntu 18.04 64bit and the latest Firefox Nightly release 74.0a1 and firefox beta 73.0b11
opening new tabs and browsing did not crash.

Can you try with the newest Firefox Nightly release from here: https://nightly.mozilla.org/ and let us know if you experience the same problem?
Also after it crashes can you go to about:Crashes and provide us the link?

It might be good also to create a new profile, you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

I'm afraid there is no debug symbols (and firefox-dbg package missing at this moment in Alpine Linux).

Most of times it dies in "/usr/lib/firefox/libxul.so" but few times I saw just failure in musl (it's like 8:1 failure ratio, it shouldn't be musl issue, since musl version didn't changed + other application are 100% stable). I'm not alone who was able to reproduce that (on armv7 machine it didn't worked for another guy).

Feel free to defer looking into it until I get all required information.

hi, I'm using firefox >=70.x all the time on my rpi2, and can't see any failure with this binary. I'm using gcc and bfd linker, but it's a glibc based toolchain. I was tinkering around for a while with musl based toolchains, and this binary would always segfault at startup. Since you're not providing any information about how you compiled your binary, I still hope this is helpfull for you.

"this bug is fixed in newer firefoxes (forgot which version) and firefox works fine on armv7 in last few months and (iirc) on 3.14-stable alpine release." - Milan P. Stanić @mps
