Thanks for the quick reply! The amount of bookmarks indeed seems to be part of the problem, yet I also discovered something else.
First some information: I have 78 bookmarks in total, in a hierarchy that is two subfolders deep. The actual json-bookmark file exported by Firefox is 33KB in size. My Internet connection is not very fast (max. 15KB/s upload). I waited 15 minutes to see whether the initial sync would eventually complete, but this was not the case and Firefox was still unusable after all the time. So I deleted all bookmarks. With nothing to sync, the browser now was usable from the start. Then I restored my bookmarks, by loading a backup file from within Firefox. Interestingly, this time the browser remained usable, beam.smp and firefox did not consume 100% CPU, and the sync began, at a rate of about 1 bookmark per minute. There were no errors and warnings in the error console, only regular messages about the ongoing transfer. It would probably have completed successfully. But out of curiosity I did not wait that long. Instead I restarted Firefox, with the result that, once again, CPU load spiked and the restarted browser froze. In short: -Start Firefox+Bindwood with existing bookmarks --> freeze, high CPU load -Start Firefox+Bindwood without bookmarks, restore them from file --> regular sync begins I also tried to get debug information according to your instructions. But with the browser frozen I was unable to access the error console. -- With Bindwood installed, Firefox is completely unresponsive https://bugs.launchpad.net/bugs/443121 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
