Yeah, seems to me that it's a brewser-side issue, though that's also a bit weird since than it should be easier to reproduce, right? I've had a fair share of front-end programming experience, but this seems like one of this 'magic' things... I think I'll try reinstalling FF, see what that does.

So, I disabled all my extensions, restarted the browser and opened brewersfriend in a new private window. The same bug occurred. See screen recording: https://gyazo.com/335d3ae197b4ecaea4a7fc5e3e799cb7 The crash only triggers with the onClick event and only when selecting the refractometer...

Well, darn. For some reason it's working fine now. I'll keep an eye on it the next few days and see if I can reproduce. Edit: restarting the browser did the trick. It's broken again.

I noticed today and yesterday that while adding or editing a log entry, if you want to change the gravity unit (in my case from Specific Gravity to Refractometer), doing so will completely freeze the webpage. This bug does not occur on Chrome AFAIK. No screenshot here scince that's frozen anyway.
