Firefox 71.0 crashes on launch...

Just updated a TW install (20191202) with Firefox 71.0, FF consistently crashes on launch:

with the reason as “MozCrashReason: MOZ_CRASH(OOM)”

Anyone else seeing this?

Reverting back to FF 70.0.1 (with a saved 70.0.1 profile) and all is OK again, for the moment I’ve locked FF at 70.0.1 and am holding off updating my other TW install.

I normally run firefox on Leap 15.1. But I started it on Tumbleweed (in a VM), and it ran fine. This was with a relatively new profile (created in November).

Hmm… Thanks… Yes, I’ve updated a couple of Leap 15.1 installs to FF 71.0 and they both start and run fine.

I don’t have too much time right this moment, I’ll investigate more fully tomorrow. The TW machine’s both have new(ish) profiles also, but it could be a profile issue, or extension perhaps, although FF on the Leap machines have the same extensions as TW. :\

A quick “google” came up with a few *buntu users with similar problems, but that was on the beta release of FF…

I have not added any extension to firefox on Tumbleweed (the firefox that I tested).

I’m having the same problem, and it seems to be a widespread issue since several users on reddit are reporting it. For me crashes even with a new profile. For the moment the “solution” is to downgrade to FF70. You’ll need to run firefox with

export MOZ_ALLOW_DOWNGRADE=1  && firefox

to allow downgrade the profile you were using.
Here’s the reddit thread: https://www.reddit.com/r/openSUSE/comments/e5xy5m/firefox_71_close_on_tumbleweed_kde/

Yes, thanks.

Indeed it does the same with a new profile, I tried deleting ~/.cache/mozilla and temporarily renaming ~/.mozilla and upon start FF still crashes. Updated a second TW machine to FF 71.0 and the same issue, as I wrote earlier I’ve two Leap 15.1 systems and they’re fine with FF 71.0…

I’ve reverted both TW systems to 70.0.1 (using a restored profile, so no need for the “MOZ_ALLOW_DOWNGRADE”)

Edit: Was about to create a bug report, but have found one already: 1158466 – Firefox 71.0 crashes on startup

Appears to be fixed in build 3.1, not yet published on OBS but for those with an OBS account can be downloaded from:

https://build.opensuse.org/package/binaries/mozilla/firefox71/openSUSE_Tumbleweed

Launches OK and appears fine so far, using it now :wink:
