6 Starting from CLI allows more options, see:
10 After copying the profile from another computer, start with the profile manager
11 and select the desired profile, after which normal starts will use it:
13 thunderbird --ProfileManager
17 I copied a profile from 4k resolution computer to a 2k one, now icons and text
18 are huge. How to scale it back down? Don't see anything relevant-looking in the
19 settings; I looked for "scale", "zoom" and "size".
23 In config editor, find property:
25 layout.css.devPixelsPerPx
27 then change its value from 2.0 to 1.0,
28 or to -1.0 (which means match current X11 settings).
32 Make a fresh profile and examine `prefs.js` diff until something looks promising.
34 $ thunderbird # Looks bad. Close it.
35 $ mv ~/.thunderbird ~/.thunderbird.bak
36 $ thunderbird # Close it. Now we have a fresh profile.
37 $ vimdiff ~/.thunderbird/newxxx.default/prefs.js ~/.thunderbird.bak/oldxxx.default/prefs.js
38 # Examine every difference until something looks promising. Value 2.0
39 # looks like a zoom value and it is refering to some pixel-to-pixel
40 # ratio - looks promising!
41 $ rm -rf ~/.thunderbird
42 $ mv ~/.thunderbird.bak ~/.thunderbird
44 # Open config editor, look for devPixelsPerPx and change to 1.0.
