indexedDB Unkown Error

I'm working with a private system webpage (only a minor set of people may see it). Since I updated firefox to firefox 35, it has been showing the error:

"IndexedDB UnknownErr: ActorsParent.cpp:412"

This also happens in safe-mode and if I turn every extension off.

In the only bugzilla bug I could find, it was set as fixed. ( https://bugzilla.mozilla.org/show_bug.cgi?id=1093223 "IndexedDB UnknownErr: ActorsParent.cpp:413" on indexedDB.open)

Firefox 35 has been out for some days now, so I believe if this was an actual bug it would already had been reported.

How do I solve this error?

Meanwhile, I'm rolling back to version 34.

I've called the big guys to help you. Good luck.


Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Make sure that the dom.indexedDB.* prefs have the default value on the about:config page.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

In about:config for IndexedDB, all values are the default.

can you try if the same problem is happening in firefox 36 beta. (the bug from the report you have mentioned should be fixed there): https://www.mozilla.org/firefox/channel/#beta

The mentioned bug looks like it will land in version 36. This is the current beta version. Does this error still happen in beta? If so, it is possible to reference this bug in a new one or make a comment on the bug with mention of all the troubleshooting already done. With in mind the etiquette

Ups. I lost the e-mail warning about the other post.

Anyway, I've just tested on firefox 36 beta 1. It is still not solved. I don't think that there's any filed bug about this specific one, so I'll file a new one.
