Provide a zoom entry on the app menu similar to the one offered on Firefox, and shown in the attached file, to allow the user to specify a percentage zoom that controls the preference layout.css.devPixelsPerPx
Many users have issues with display size, often associated with changes of monitor or moving a profile to a new device, however, Thunderbird offers no user interface to handle this common issue. Instead relying on the use of the config editor.
This is a separate issue although related to the zooming of email bodies

I noticed an issue which I'm not sure if it's our fault or if it's coming from the toolkit.
I set layout.css.devPixelsPerPx to 1.25 as I'm on a large 4k monitor and I don't want to use fractional scaling on the OS display settings.
Everything looks good, except, after restarting TB the layout scales to respect that 1.25 ratio, but the font size doesn't follow.
I had to reset layout.css.devPixelsPerPx to 1, restart TB, and set again layout.css.devPixelsPerPx to 1.25 in order for the font size to follow properly. But the problem returns after every TB restart.
I need to check if this happens also on Firefox.
Matt, would you be able to confirm if this happens to you as well?
I tried with a daily build on windows and the changes were reflected in the config editor as soon as I updated the setting. No restart, no nothing special at all. Just changed the -1.0 to 1.25 and things changed immediately.

Thanks for checking.
After further investigation the issue reported on comment 1 (ui scaling not maintained after restart) seems to affect only Linux.
