• Do you have more than 5k bookmarks?

There is a limit to the number of bookmarks that can be synced to Android mobile devices with Firefox for Android. However it should not be crashing.

The crash signature that you posted is an out of memory error. What steps are you taking before this crashes? Also, if you disable Sync temporarily on the device can you visit other sites?

Start Firefox in Safe Mode {web Link} by holding down the <Shift (Mac Options) > key, and then starting Firefox. Is the problem still there?

Reported bugzilla error for Win 7 vers. FF 34.0.5. Unable to access any websites not already being accessed by bookmarks or Firefox Sync setup. Ran Norton this is not a virus issue or spam issue. Would like to access other websites, ie ebay, paypal, etc.. This issue started appearing about a couple weeks ago and I thought it would fix itself. Here is the url for more info from Mozilla https://crash-stats.mozilla.com/report/list?product=Firefox&range_value=14&range_unit=days&date=2015-01-08&signature=OOM+|+small&version=Firefox%3A34.0.5. Dumped cookies/cache. Would prefer not to reset FF 34.0.5.

Is anyone looking at this for Windows 7 64 bit users and not Android and OS users?

Read the blog, this is a Windows 7 64 bit desktop issue for FF 34.0.5

Ok, version 35 is coming out tomorrow, however it is also possible to try safe mode as Fred has suggested above.
