Hi

Please appreciate that the Nightly version of Firefox for Android is a work in progress and may have unresolved issues from time to time.

Typically issues like this get resolved very swiftly so checking for updates is a good idea.

Further to this, if you type about:crashes into the address bar and select the latest Socorro link, a web page will open. If you copy and paste the address of that page into a reply to this thread we may be able to look into this further for you.

Thanks for the reply.

I installed Firefox Nightly only because it was not possible on Android to use a particular add-on anymore with the regular Firefox .

Further to this, if you type about:crashes into the address bar

It's not possible unfortunately because Firefox doesn't start.

You may wish to install the beta version as well - it can also support a wider range of add-ons using the same method.

There are only 15 extentions compatible with Firefox Beta and mine isn't one of them.

As with Firefox for Android Nightly, you can use this process which might help:

My extention is installed already. I just need to start Firefox Nightly without crashing.

Okay, in that case you may have to wait for an update that fixes the issue. The Nightly build is designed for testing and developers and not really as a main browser.
