xfs, what version of IceCat were you trying to install? Did it match the architecture of your CPU?
What is your device make and model? What's your device CPU architecture and clock speed, and how much RAM memory does it have? Also, is there enough storage space to install stuff? Why do you still have Android 4.1.2? I have Android 4.1.2, too, so I can relate. I've only installed IceCatMobile 52.6.0, but that install included about a dozen add-ons that I'd never have any use for, and which almost prevented me from using IceCat, because all those add-ons were active by default, were chugging precious amounts of RAM (updating?), and were nearly impossible to deactivate. I cannot say, if these add-ons were included by upstream, or by the package maintainer at F-Droid. If you're worried about strange JavaScript, then you can install NoScript. It blocks most JavaScript by default, and has a tiny whitelist that you can clean up later on. If you have a pre-57 version of a Firefox derivative — including IceCat — then you can install NoScript Anywhere from https://noscript.net/nsa/ But it's quite difficult to modify that whitelist on a subdomain level: you need to know your way around about:config, and you'll need good knowledge of Vim (VimTouch for Android), which was once available at F-Droid, too. IceCat 60.x and newer require the WebExtension edition of NoScript. It's less functional than classic desktop NoScript, but with a more functional user interface than NoScript Anywhere. You can get that from https://noscript.net So, anyway, in the WebExtension NoScript, you can set NoScript to display full domains, you can clean up the built-in whitelist, you can temporarily allow certain Google domains (if need be), and then not worry about JavaScript at all for sites that you won't want to track your device. NoScript is the least-resource-intensive blocking tool. If your device has 1 Gb or more RAM, you can also add uBlock Origin for adblocking and for more fine-grained permissions, but it has a steeper learning curve, and uBlock Origin does not default to blocking everything. For pre-Quantum Firefox and IceCat, I can recommend the following extensions: * Console (1.1.1.1) * Cookie whitelist for Fennec (0.9.5.1) * Copy Profile (1.1.1) * PageInfo Viewer (1.0.0.1) * Privacy Settings (0.2.4) * Proxy Mobile (0.0.10) — you can use apps that present a proxy in your device * Stylish (2.1.1) * View Source Mobile (0.1.1.1) * AddCertificate (1.0.10.01.1) All of the above extensions are not resource-hungry. But these are pre-Quantum versions of extensions, and addons.mozilla.org no longer hosts them. If you feel adventurous, then you can search for them on the Interwebs, if you've decided on a pre-Quantum version of IceCat. Also, to prevent automatic updates to WebExtension versions, then in about:config, set extensions.update.enabled to false. Do keep in mind, that pre-Quantum versions of IceCat are less secure, and do not have as good support for newer web standards. Many sites may hang your browser pre-Quantum IceCat on what I see as malformed CSS, fonts, and terrible JavaScript. Sites that use these fonts, or which increasingly rely on CSS variables (such as the new Skype for Web), will make pre-Quantum IceCat Very Slow. And if you want a device without Android, then see, if you can install Sailfish OS. For secure Android-based stuff, I could have at one time suggested CopperheadOS, but its original developer was kicked out of the project amidst deep acrimony. Devices with non-Google Android are rare. The Nokia X family — from before the Nokia mobile division was sold to Microsoft — is the only such series of Android devices, but they separately promoted Nokia and Microsoft products. Nokia X devices are now rare, and might even be considered collector's items. -M. 2019-04-01 23:45 GMT +03:00, x...@riseup.net <x...@riseup.net>: > Hello, > > I cannot install IceCat using F-Droid on Android 4.1.2. > > The app gets downloaded and when it comes to > installation, the required permissions are shown and I > have to choose between "Install" and "Cancel".
