Install older versions

Hello compis1, It’s 3 years later but I am going to add what I found out in case someone else finds this.

First, find out the app id. For example I searched “flabhub firefox id” , yes I am a googler lol. In any case, Firefox flathub ID is “org.mozilla.firefox"

Second, you use terminal and type “flatpak remote-info --log flathub org.mozilla.firefox” This will display to you information along with previous commits (Git commits I assume).

Lastly, if there is a version you would like to revert on that list, which is unlikely due to pruning but if the version is recent you might be in luck. Copy the commit and add it to the line that frank.fh provided. For example, for Firefox I found 7 commits. One of them looks like this:

Commit: 5a35aad47195f8e172eef169fd0b6a7cf251c4caaaec4df0911920ed3f96bb9c Subject: Export org.mozilla.firefox Date: 2025-12-09 13:47:52 +0000

the line would be : sudo flatpak update --commit=5a35aad47195f8e172eef169fd0b6a7cf251c4caaaec4df0911920ed3f96bb9c org.mozilla.firefox

I hope this helps
