I’m hitting this reliably several times per day, FWIW; I’ll glance at my phone and notice a notification telling me “Sorry, Firefox Nightly had a problem and crashed”. Logcat shows “ActivityManager: Background start not allowed: service Intent { cmp=org.mozilla.fenix/.downloads.DownloadService (has extras) } to org.mozilla.fenix/.downloads.DownloadService” which is what brought me to this issue here.

Looks like the Play Store has a update for Nightly available for me right now. Not sure if it has the fix mentioned above yet (I’m guessing yes since it was merged 23 hours ago). In any case, I can report back regarding whether this seems fixed or not.

Looks Downloads related, @Amejia481 or @kglazko could you coordinate/take a look? If this is in Nightly, it may be in Beta too so if it’s a problem we’ll want to uplift this fix.
