On principle I don't use Chrome/chromium, unless a project requires it. It's not a bad browser but I wonder if running a google executable on your computer is like inviting a thief into your home. I still remember when chrome first launched and they would check for updates multiple times a day, every hour or something like that. And what's this virus scanner they offer?

Anyway, I run ff most of the time, and there's a site that I use daily that requires a login. Used to be I would receive a recaptcha challenge maybe one or twice a week, even though logged in. No problem, probably using recaptcha to throttle bots I think.

For the last week plus there's been a fundamental change and I'm receiving multiple recaptcha challenges in the same session, even though I'm signed in, max so far has been 4 in the same session covering maybe 30minutes or so.

Not sure if it is the site itself which is to blame for a poor implementation, or if this is google.

But co-incidentally this happens just as google announces recaptcha 3. Conspiracy nuts might say this is google leveraging their effective captcha monopoly to drive users to chrome.
