I’m encountering an issue with ArcGIS Experience Builder: after upgrading to Mozilla Firefox version 145.0, the Layer (or Map Layers) widget fails to display. Has anyone else seen this behavior?
our 11.3 instant apps apps won't load with firefox 145 either (and they will load with 144).
does it help to uninstall and install a previous version on the server itself?
yes just discovered this with an experience builder app today. 11.5. exactly as you described, new firefox update and now the layer list widget opens but fails to display any actual layers.
Happens to us on both AGOL and 11.5, and also affects the map viewer (only the map itself loads alongside the usual site header, but none of the usual side panels).
also seeing UI not visible on left side of map viewer w/ 145.0.
esri support saw issue after updating to 145.0
Also seeing the same behavior after updating to Firefox version 145.0.
This isn't just happening in Experience Builder nor is it limited to the layer list widget. I have a custom JS application built with Esri JS 4.33 and I am experiencing the same thing with my arcgis-layer-list map component.
I have also experienced these issues. Only on Firefox. Also tested on Enterprise with all patching done last night. Has this received Bug status yet?
I just opened up a similar support ticket with ESRI for Enterprise 11.3 Map Viewer. They did confirm the behaviour was reproducible.Also interesting is that it works again in Firefox 147 (Nightly Build) so hopefully Firefox will release soon.
Interesting. Yes, I hope Mozilla moves quickly on this. It's one thing for me to shift to other browsers. But asking clients to do so is not a good option. Looks bad on the developer.
I will add that in hope of solving the issue, I have started to migrate my applications to the new Esri JS SDK 4.34. And the issue persists there - so upgrading to 4.34 does not solve the problem. And besides components like arcgis-layer-list and arcgis-legend being wonky, some of my responsive behavior is not cooperating. I use the Bootstrap front-end framework for my applications. I have JavaScript in place that moves specific components around depending on either initial page size (like a mobile device vs a desktop) or even page resizing actively carried out in a desktop browser. This code has worked for years. And in both 4.33 and 4.34, it still works in Edge, Chrome, and Safari. But it does not work in Firefox v145 and above. I downloaded Firefox Nightly (v147) and the layer list and legend components seem to work again - but the responsiveness still does not. And the application on a mobile device does not load properly at all.
Yes, I can confirm also Map Viewer is definitely affected both on ArcGIS Enterprise 11.5 and ArcGIS Online using Firefox 145. Hope to see soon any updates from Mozilla.
Same issue.
I noticed my Chrome users having issues after the latest update to Chrome covered at https://community.esri.com/t5/arcgis-online-questions/message-asking-for-access-to-local-device-when/td-p/1662179
The Chrome issue is due to a security feature added in the latest update of Chrome, could this be related to a similar update in Firefox?
Hi, Yes Firefox is aware of the browser update causing issues in Map Viewer and other applications and are working on a patch that should address it. In the meantime, everything should be ok in other browsers and FF versions.
Hello, Firefox released an update in that fixed this issue https://www.firefox.com/en-US/firefox/145.0.1/releasenotes/ Please let us know if you continue to see issues with the updated version.
Hi @BrantGossett
This is known limitation, we have a bug logged for the same
