Map Viewer issues when using Firefox Version 145.0

TheaBlock — Thu, 13 Nov 2025 22:02:41 GMT

I noticed that when using Firefox version 145 the toolbars to edit a map are not there. When working with the same map logged into the same account in Edge or Chrome the toolbars are visible. A coworker with Firefox version 144 checked and they could see all the toolbars. They then updated Firefox to version 144 and were no longer able to see them. Based on this it seems that Map Viewer is currently not fully operational in the latest version of Firefox.

What I see using Firefox version 145

What I see in using Chrome

Wow- that's interesting. I just noticed that same behavior on my end. Also, the Map Viewer keyboard shortcuts do nothing (Alt B opens the Bookmarks Browser Menu instead of showing the Basemap Gallery)

Hi, Yes Firefox is aware of the browser update causing issues in Map Viewer and are working on a patch that should address it. In the meantime, everything should be ok in other browsers and FF versions.

Unfortunaley the bug seemingly reappeared in the latest Firefox version (145.0.2). Our map viewer and apps do not load in Firefox anymore. In Chrome and Edge they work fine.

I have updated my Firefox to 148.0.2 and the Map Viewer is still very buggy. Many functions either have display errors or do not appear at all while they do in Chrome and Edge.

Are there any news on this mattter that ESRI could share with us ?

Hi, I just downloaded FF 148.0.2 and am unable to reproduce this issue. It may be worth contacting support if this issue persists for you. We haven't received any similar reports yet, but will keep an eye out.
