If you use Firefox for Android, you may have noticed that the Google search results are not displaying the usual “Mobile Friendly” tags that normally display before all mobile friendly search results.

This screenshot was taken with the Firefox for Android app, with a version that hasn’t been updated to the newest release.

It isn’t known why the mobile friendly tag isn’t being displayed, but multiple support threads reveal that Google reportedly sends a different version of the search results to the Firefox Android app than they do to Chrome’s app.

Here is the same search on the same phone with Chrome.

She also tried the search on a lesser known browser, Dolphin, and it showed the mobile friendly tag.

The loss of mobile friendly tags in the search results has the potential to hurt websites, especially if searchers are used to seeing the tag and mistakenly assume those sites are not mobile friendly.

As a related note, they are being displayed on Bing results in the Firefox for Android app.

These results were also confirmed on another Firefox for Android device, this one upgraded to the current Firefox that was just released – 38.0.1.

H/T to both Kristine Schachinger, who noticed and sent the multiple screenshots and to Danny Goodwin, who downloaded the latest version to confirm the missing mobile friendly tags.
