"AttributeError: 'YahooBackupScraper' object has no attribute 'br'" when running with Firefox driver

Running yahoo-groups-backup.py scrape_files $GROUPNAME fails with the following message:

This particular problem does not occur when using the chrome driver instead, though this driver fails for other reasons (for which I will file a separate report).

pip install -U selenium got me past this, though now something is failing in Firefox on the login page. (Still, a step forward!)

Stackoverflow where I found this.

[hrenfroe]

I can't find the citation now, but FF 53 changed a default setting so that it uses the JSON viewer by default, which confuses Selenium. I tried to initialize the temporary profile with the setting to disable it, but gave up and used Chromedriver instead.

This is exactly where I'm at re: firefox failures

Dumb question, but possibly useful to people who end up here: how do I make selenium use the chrome driver instead?

You want ./yahoo-groups-backup.py scrape_messages --driver chrome your_group_name_here. You are likely to run into issues detecting the login page after that, and I recommend my fork to deal with that.

Thanks! Hope to get your fork working.
