Where are firefox extensions stored
Export/import passwords in firefox browser
I’m aware that there are many “proper” ways to install Firefox plugins. I’d like to know where the folder for linking shared-object (.so) files like libnpjp2.so and libflashplayer.so is so I can install plugins the “old-fashioned” way. I would have placed it in /.mozilla/firefox/*[profile name].default/browser/plugins in Firefox 21, but that folder no longer exists. When Firefox evolves, it continues to hop around. All of the plugins that I would have placed there are still visible in about:plugins.
Ubuntu 16.04 LTS is the version I’m using. This article describes how to allow Flash Player in Mozilla Firefox in Ubuntu. If there isn’t a lib64 directory, simply copy the appropriate file to /usr/lib/firefox/browser/plugins/. It also works well, in my experience.
How to backup & restore bookmarks in firefox
They store their data, like all apps, below the /data/data directory, in a directory named after their package name — which is what you will see after the “id=” in the playstore URL. As a result, data for Firefox should be stored in /data/data/org.mozilla.firefox.
Firefox might (or might not) use some storage on the sdcard for userscripts and other profile details, so you might check if you see a similar directory structure there. Certainly not with the “doubled” /data, and possibly only called “firefox” — I can’t verify because I don’t have Firefox enabled, but it’s worth a look.
All of the data is stored in /data/data/org.mozilla.firefox, which means you can only read it if your computer is rooted, as Izzy said. The path files/mozilla within that directory has a layout very close to your /.mozilla/firefox directory on a Linux desktop: it has a profiles.ini and a directory asdf12yz.default that contains all the interesting files.

Adobe Flash Player support will end on December 31, 2020. As a result, none of the browsers support the NPAPI and PPAPI plugins. There will also be no further bug fixes or security patches for the project. 1st
The flashplayer-standaloneAUR kit can be used to install an older standalone version. This kit predates the insertion of the hard-coded end-of-life clock in Flash Player and thus continues to work.
Gnash is a free (libre) Adobe Flash Player alternative. It supports the SWF format up to version 7 (with versions 8 and 9 in development) and about 80% of ActionScript 2.0 and is available as a standalone player for desktop computers and embedded devices as well as a browser plugin.
Lightspark is yet another free alternative to Adobe Flash that aims to embrace newer Flash formats. Lightspark will fall back on Gnash for older content, allowing users to install both and get a wider range of coverage. While it is still in early stages of growth, it currently supports a range of popular websites.
How to backup and restore your profile in mozilla
Your Firefox profile contains your personal information and settings, including your home page, bookmarks, extensions (add-ons), toolbars, and saved passwords. All of this data is saved in a profile folder that keeps your data isolated from the Firefox software, ensuring that your data is preserved even if Firefox crashes.
If you’re having trouble with Firefox, switching to a different profile will help you troubleshoot. You’ll have to track down your profile folder if you have a customization that includes it.
Copy the folders in the Profiles folder to an external hard drive or a cloud service to back up your profile(s). If you want to start Firefox from scratch, you can also delete your profile folder.
You can build several profiles with different settings, bookmarks, extensions, and toolbars in each if you really want to get your hands dirty. If you want to test plugins or troubleshoot problems in Firefox without messing up your main profile, this is a good option. You might also create separate profiles for different users or circumstances, such as “Work” and “Personal.”
