I had the same issue. I need the name of the HTML element. In Chrome I get the name with path. In Firefox I tried with composedPath, but it returns a different value. For solving my problem, I used e.target.nodeName. With target function you can retrieve the HTML element in Chrome, Firefox and Safari. This is my function in Vue.js. SingleFile is an extension that not most individuals will find useful. For those who actually need to have an efficient way of saving webpages, without having to deal with lots of associated files.
I should probably try this. I wonder how it will compare with what I'm doing:- SingleFile is a Web Extension (and a CLI tool) compatible with Chrome, Firefox (Desktop and Mobile), Microsoft Edge, Vivaldi, Brave, Waterfox, Yandex browser, and Opera. It helps you to save a complete web page into a single HTML file.
- SingleFile for Firefox 1.18.82. Use this neat extension if you want to save a browser page in one single HTML file, with all the r. Apr 20th 2021, 00:57 GMT.
I simply use the browser's (Firefox) save page feature (ctl-s). Then every now and then, I convert the folder with these pages to a squashfs image (which de-duplicates all the CSS, JS, image files that are saved multiple times). I then use shell tools to search (ls grep locate etc.). This doesn't save the URL, but I also maintain a private 'bookmarks' Git repository for more interesting bits where each bookmarked resource gets its own file (in a descriptive hierarchy), along with thoughts and notes.
What works well is that I am somewhat selective, complete trash doesn't end up being archived, it's pretty space efficient. It's also simple to wade through (in the shell), each saving action is just a file and folder pair. Also often I use the reader mode Firefox feature, and then save that (i.e. I save what I saw, not what was delivered). What doesn't work so well is that saving the page is often a bit of a hassle, often Firefox reports save errors then I just ctl-s again to see if the previous attempt succeeded, if not, hit the reload icon in the download task list which apparently forces it. Also, that it saves embedded videos, haven't figured out yet how to disable that, so periodically I remove videos again. Also, when saving multiple pages from the same site, links to other pages don't go to the local mirror. (In cases where it's important, I use wget -m -k.)

What add-ons are supported on the new Firefox for Android?
Currently, only a limited number of extensions in our Recommended program are supported on the new Firefox for Android (codename: Fenix) release channel. These extensions can be found and installed from the Add-ons Manager. See this article for more information.
Will more add-ons be supported in the future?
We wanted to ensure that the first add-ons supported in the new Firefox for Android provide an exceptional, secure mobile experience to our users. To this end, we have prioritized Recommended Extensions that cover common mobile use cases and that are optimized for different screen sizes. For these reasons, it’s possible that not all the add-ons you have previously installed in Firefox for Android will be supported in the near future.
Will add-ons not part of the Recommended Extensions program ever be supported on the new Firefox for Android?
Singlefile Firefox Update
We would like to expand our support to other add-ons on the release channel, and we are continuously working on increasing support while taking into account usage and feedback to ensure we are making the most of our available resources. We will post updates to this blog as plans solidify each quarter.
Can I install extensions from addons.mozilla.org to Firefox for Android?
Currently, you cannot install extensions directly from addons.mozilla.org to Firefox for Android. In the near term you will need to install extensions from the Add-ons Manager on the new Firefox for Android. However, we are thinking about how to support the installation process from AMO as we evaluate future plans.
Can I install other extensions on a pre-release build of Firefox for Android?
Yes, there is an override in Firefox for Android Nightly that you can use to install extensions listed on addons.mozilla.org (AMO) via AMO’s Collections feature. See this post for instructions. Currently, you cannot install an unlisted extension on Firefox for Android Nightly.
We’re working on building a pref for to allow persistent loading of an arbitrary extension. Once we have more details, we’ll post updates to the Add-ons Blog.

How can I test my extension’s compatibility with Firefox for Android?
You can find more information about developing and testing extensions for Firefox for Android on Firefox Extension Workshop.
What happens to add-ons during the migration from the old Firefox for Android experience to the new one?

What is GeckoView?
GeckoView is Mozilla’s mobile browser engine. It takes Gecko, the engine that powers the desktop version of Firefox, and packages it as a reusable Android library. Rebuilding our Firefox for Android browser with GeckoView means we can leverage our Firefox expertise in creating safe and robust online experiences for mobile.
