- What’s wrong with snap? - It’s really slow on my older Chromebox converted to Ubuntu. Starting Firefox would take longer than 30 seconds to start when on snap vs native binary. - Snap caused me to move my older PCs from Ubuntu to Debian or Linux Mint 
- Nothing. Like there’s nothing wrong with Flatpak either. - However, the Flatpak/Snap version of Firefox have some issues. Especially with some browser extensions that need to communicate with tools/apps installed on your system. Their sandboxed nature prevents them from doing so. - For example, a browser extension for a password manager won’t be able to communicate with your local password vault app. A video downloader extension won’t be able to use the download tool or access the folders you want. Etc. - And the problem here is that in Ubuntu flavors, Firefox is exclusively available as a Snap package from Ubuntu’s official repos. So you can’t install a .deb. You have to add the external mozilla repos to your sources to do so. - This becomes a bit too technical for most users who are not very tech literate. - Snap provides ways for extensions to communicate with other apps (and AFAIK Flatpak does too, but I haven’t used a browser Flatpak in a while). The Plasma Integration extension uses these. 
 
- Firefox snap on raspberry pi was mostly unusable, the deb worked fine, as an example.
