Hi

Which extension is telling you this?

Webmail Ad Blocker

The app developers page is asking me to update Firefox, the Addon is updated. My Firefox is v98.0.1

On right of your first post, in your Question Details > More system details > your User Agent used to post this thread is Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

It appears you have a modified UA as either you set the UA to display as if you have Firefox 91.0 or you have enabled privacy.resistFingerprinting as one of the things it does is change the UA to be the current Extended Support Release or ESR which is Fx 91.7.1 ESR based on 91.0 Release.

I'm still trying to apply the suggested changes, without bricking Firefox!!! Will definitely keep you posted.

Thanks for your help.
