1332209 - HTML/CSS Bootstrap menu of one-page website does not work

Status: RESOLVED INACTIVE

(Firefox for Android Graveyard :: General, defect)

Description

[David Bourguignon]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161208153507

Steps to reproduce:

I opened http://lesenergiques.org/ on my Samsung Android tablet device (Galaxy Tab III Lite) using Firefox and Chrome.


Actual results:

On Chrome for Android, the HTML/CSS Bootstrap menu (top-right corner, three parallel bars) of this one-page website worked fine.

On Firefox for Android, the very same menu did not work at all (you click on an item, and nothing occurs).

I suspect two things:
- Firefox for Android ignoring anchors
- Firefox for Android introducing some "optimization" on that prevent reloading the same page programmatically (which is necessary on this one page websites)

Nota bene : using a Firefox for Windows, and the development tool called "adaptive view", I simulated the same screen configuration. And this time it worked fine!

Therefore, Firefox for Android "optimizations" are certainly the root cause of this problem.


Expected results:

Chrome (for Android) is the reference browser nowadays. Firefox for Android should deliver the same user experience on such a straightforward case. Unfortunately it does not. Thanks in advance for your help!

Mike do you or someone from your team have time to look at this?

David I assume that you are using the most recent version of Bootstrap v3.3.7 or the 4.0 prerelease?

Kevin, I do confirm that this website is using Bootstrap v3.3.7. Thanks in advance for your help!

Hey David, we can't reproduce on our devices (or on emulators) -- have you tried in Nightly on the same device? None of us have a Samsung tablet though, it's not impossible for it to be a device-specific issue.

Hi Mike, thanks for the feedback! In fact, I do confirm that the bug does not show up on emulators.

I suspect an implementation issue in the Android version of Firefox but I do not have tried in nightly on my device. On your side, did you try on a Samsung tablet?

I suggest we let this open, and wait for a potential improvement with a future Firefox release.

I don't have access to a Samsung tablet, unfortunately. If you're willing to install Nightly to check, that would be really helpful:

For the record, it seems it's not happening on my Google Nexus 7 tablet or Samsung Galaxy phones either (Androids 4 and 6). I just tried today's nightly and Firefox 51.0.2 on my tablet and phone, and the "hamburger" menu is working as expected. I don't see any notes in the error console, either.

Hi Mike and Thomas, thanks a lot for your feedback. I just tested again on my Android tablet with FF v51.0.3 (unfortunately, I do not have time to play with nightly builds).

The behaviour has changed slightly: the hamburger menu works once, then stops working when I try to select another menu item. If I switch to another tab and do something there, the hamburger menu gets a reboot (so to speak), and starts working again... once.

IMHO this is definitely a FF issue on the Android tablet. On the very same tablet, Chrome handles this perfectly.
