I think I’m finally finished with edits on my Firefox Customization Post.
To recap:
- introduced fully functional landscape mode
 - introduced several optional dynamic popups configurations
 - fixed extensions and the new Unified Extensions Menu
 - fixed and redesigned 
aboutpages (about:addons,about:preferences, etc.) - created a style to mimic Firefox for Android, complete with colors
 
I realize there is a lot of code, but I did make sure that there are sufficient comments.
I am hoping that someone from Purism can review my code so that it can be incorporated into PureOS. I also think it could make a cool blog post or video on puri.sm/posts demonstrating the progress made on the browser and the customizability of the Librem 5.
@dcz, @dos, and @guido.gunther, what do you think?
Edit:
I’m really sorry, but I did make another round of edits to all of the files listed in the “Updated on November 5th 2023” section of October 2023 Haloween Update (post 55).
