Ungit crash on Firefox

[dregad]

Greetings,

I am running Ungit on a Cloud9 workspace (Ubuntu 14.04). This has been working just fine for many months, but today I am getting Whooops Something went wrong, reload the page to start over. There haven't been any changes on the system . I tried upgrading Ungit (from 1.10.3 to 1.10.11), but the problem persists.

It's worth mentioning that the error occurs only with Firefox. When using Chrome Ungit loads just fine, no idea why.

I am not seeing any errors on the server side (with --logLevel=debug)

Not sure what to do next (except using Chrome 😉) - your advice would be appreciated. If you need further information, please let me know.

Thanks in advance

Maybe this is a problem with some of your browser extensions. See #887
We are currently getting a lot of issues about this...

@campersau many thanks for the hint. After reading #887, I tried Firefox without extensions (why didn't I think of that before !?), and it worked perfectly. Then I re-enabled them one-by-one, to find out that Adblock plus was causing the issue. I will analyze this in further details and report the problem to them. Thanks again.

For the record, the block is triggered by the easyprivacy filter, offending filters are
