On various sites, e.g. DuckDuckGo search results, parts of the text are missing. Sometimes it's one or more complete lines, sometimes it's part of the line (left, right, middle, upper, lower part). It looks like rectangles in background colour hide the text. Zooming changes the affected zones and generally makes more an more text visible again. Selecting the missing text also makes it visible. This happens on only one device. Complete deinstallation and reinstallation of Firefox for Android didn't help.

Some text disappears on both Firefox and a Firefox Focus on a CAT S22 Flip phone. I am able to glimpse at the text by long-pressing to evoke the menu. Please see the demonstration video linked here: https://youtube.com/shorts/ZxKtVFrvQkU?feature=share

having a problem on many websited including wikipedia on android firfox, unless zoomed in much of the text is inivisable, cutting off half way through words, as you soom in text reapears in bits and pieces as if gradulally being uncovered
