Usually, when browser updates come out, it’s obvious what to do if you’re running that browser on your laptop or desktop computer.
But we often get questions from readers (questions that we can’t always answer) wondering what to do if they’re using that browser on their mobile phone, where version numbering is often bewildering.
In the case of Firefox’s latest update we can at least partly answer that question for Android users, because the latest 88.0.1 “point release” of Mozilla’s browser lists only one security patch dubbed critical, namely CVE-2021-29953:
This issue only affected Firefox for Android. Other operating systems are unaffected. Further details are being temporarily withheld to allow users an opportunity to update.
The bug listed here is what’s known as a Universal Cross-site Scripting (UXSS) vulnerability, which means it’s a way for attackers to access private browser data from website X while you are browsing on booby-trapped website Y.
