I do not know how to access the developer console in Firefox mobile

[hungrymonkey]

Navigating from Firefox mobile beta and release from https://drafthouse.com/](https://drafthouse.com/) to food & drink will show an "OK"

This website have so many random behaviors.

I cannot reproduce this behavior as directly navigating to https://drafthouse.com/food-and-drink fixes the "OK" only page behavior. This behavior requires a fresh firefox install.

[softvision-raul-bucata]

We appreciate your report. I was able to reproduce the issue using Firefox Focus (Release and Nightly) and on the latest Firefox Fenix Nightly. The drop-down menu does not respond.

Tested with:

Browser / Version: Firefox Focus Release 117.0 (372332003-🦎117.0-20230821145345🦎)/ Firefox Fenix Nightly 118.0a1 (2015970787-🦎118.0a1-20230827090435🦎)/ Firefox Focus Nightly 118.0a1 (372400408-🦎118.0a1-20230827090435🦎)
Operating System: Samsung A51 (Android 11) -1080 × 2400 pixels 20:9 aspect ratio (~405 ppi density)
Operating System: Google Pixel 3 (Android 12) -1080 x 2160 pixels, 18:9 ratio (~443 ppi density)

Notes:

1. Reproducible regardless of the status of ETP.
2. Reproducible on the latest build of Firefox Fenix Nightly.
3. Works as expected using Chrome.

Moving this to NeedsDiagnosis for further investigations.

This error becomes spit out.

@hungrymonkey, @softvision-raul-bucata is this still not working for you? I just tried it on my phone and it's working fine. The site does seem to be using FastClick, but it isn't breaking anything on the page for me. Does it maybe only happen on Android 13 somehow?

Edit: @ksy36 says it reproduces for her, so hopefully we can figure out why it's not consistent.

[wisniewskit]

Ah! We found it. FastClick has a special case in its notNeeded function:

documentElement.scrollWidth <= window.outerWidth

It seems that on my devices, this is true, so FastClick doesn't activate, but for some reason on Ksenia's device it's false, so FastClick does activate. Weird! At least we should be able to work around this inconsistency.

@wisniewskit Why don't you try to contact the website?

@hungrymonkey we do generally attempt outreach, but there are many other sites using FastClick, and it and some of those sites are no longer actively maintained, so finding out how to deal with it without having to contact every site is also worthwhile.

Would you happen to be a dev for drafthouse.com?

[hungrymonkey]

Nope. Some user.

[hungrymonkey]

If I was a dev for drafthouse.com, I would had already debug and fixed it.
