Looked on Google Play for Firefox, wanting to download it onto a Acer Chromebook There were several versions, and I selected the one the felt right. I now try to adjust settings (esp Zoom), and this version doesn't provide that option. Need it for vision-impaired wife that will be primary user on this device. I pull up support and the title of the page says Firefox for Android. So, first, is That the version that should be used on Chromebook? None of the usual settings appear (incl Zoom), or uninstall for that matter. (so I can't uninstall to start over, looking closer at which version I download). Thanks in advance for any thoughts !
