My computer has Ubuntu 16.04.2 LTS 64-bit and Firefox 52 64-bit.
For one of the government web sites, because it is using browser Java plugin to sign documents, I need to install:
- Firefox ESR 52. Ordinary Firefox 52 does not support Java as browser plugin anymore, because NPAPI was removed (source).
- Firefox ESR 52 32-bit. I know for sure Firefox 32-bit only supports Sun Java on Windows, but not sure if this is also a limitation on Ubuntu. If it is, I need Firefox 32-bit version and not Firefox 64-bit version. 2
I know I can install Firefox 32-bit like using:
install Firefox 32-bit in terminal:
sudo apt install firefox:i386
but installing Firefox 32-bit will uninstall Firefox 64-bit, which I would like to keep.
download and extract Firefox 52 ESR 32-bit from 2.
Is there any other was to install Firefox ESR 52 32-bit and also install Sun Java 32-bit on Ubuntu 16.04.2 LTS 64-bit without uninstalling Firefox 52 64-bit?
