Instead of using TF&SC (currently for TB 60 and lower), try this: Edit/Preferences/Advanced/General/Config. editor, right-click the preference layout.css.devPixelsPerPx, Modify, and enter a value of 1.20 or 1.25. That will zoom everything, including the global search tab text.

Thank you! That at least makes the search results readable. Shouldn't the results take up more of the available width by default though?

I don't know why it doesn't use the full width, and haven't yet found a way to change it. Note that the 'Open email as list' button under the histogram shows the results in a Threads Pane view.

Thanks for helping and i did try to find that preference and edit it but that preference was not on the list....so i am still left with tiny fonts on the menus and folders and no way to install an updated font add on that will help. I dont want to go back to the old version of ThunderBird. Thanks

The preference is there even in a new profile created with TB 68. Type pixels in the search box in Config. editor and you will see the correct pref.

See the pictures here.

Hello There, It does help me , but I was needed to put it on 2.8... to make good font size.

Thank you all for your support. Koby Peleg Hen

It doesn't change the size and readability of the menus and message/subject list.

How do I get to "Edit/Preferences/A.../Gen/Config.editor? Is that on the command line or am I supposed to be able to reach through a menu system?

On OS X, it's Preferences/Advanced/General/Config. editor, and on Windows it's Tools/Options/Advanced/General/Config. editor.

Thank you for that clarification sfhowes. I did not want to go back to OS X Mail.app.

It's a good fix for the basics, but it's not quite correct to say it will 'zoom everything', however. It doesn't change the mail toolbar font, which I would at *least like to bold or increase the font size.

TB is still woefully behind where it could and should be, in 2020.

If you want to control specific elements of the UI, you have to apply css. Here is a sample that includes the fonts for the Menu and Mail Toolbars, the submenus and context menus, and (at no extra charge) fonts for the Threads and Folder Panes:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

/* Mail Toolbar */

#mail-bar3
{ background-color: cyan !important;
  font-size: 16pt !important;
}

/* Menu Bar font */
menubar > menu
{ font-size: 16pt !important;
}

/* Submenus and context menus font */
menupopup,popup {
    font-size: 14pt !important;
}

/* Folder Pane font */
#folderTree > treechildren {
  font-size: 10pt !important;
  font-family: Verdana !important;
}

/*  Threads Pane font */
.tree-rows {
    font-size: 12pt !important;
    font-family: Verdana !important;
}

font-weight:bold !important;

Nice. Thank you.

Thank you very much for this info, it enlarged everything for me. I have been dealing with trying to get to know Windows 10 in a new laptop and it is very time consuming and annoying, so to have Thunderbird go AWOL in my old laptop and kill TF&SC resulting in major eye pain on top of the Windows chaos had me trying to decide if I should download an older version of Thunderbird or throw all the electronics in the back pond for the fish and alligator to pee on, which still seems like a very good idea since it is taking forever to try to figure out if it is possible to terminate Synaptics touch pad from hell in the new Omen laptop. Microsoft and HP outsourced tech support both say no, it is there to stay. Some articles say to change language in the bios. Talk about a bad omen.

Thanks again for saving me a lot of time and aggravation, hope life treats you well.

I entered 1.25 and everything got smaller!

I do not see any way of increasing the size of the messages in the inbox. I have recently returned to Thunderbird after a long absence, as years ago my new ISP wouldn't support Thunderbird. I am on a mac and have gmail forward to thunderbird. I can increase the size of each message, but can NOT increase the size in the in box of incoming messages, and I can barely read them

Pathetic..... Mozilla can easily make one of 2 changes: - Build in a type size changer for the inbox. That is a minor matter. - Work with the dev. for Theme & Font Size Changer to make that compatible with TB 68... One engineer with access to that code, [estimating] 4 hours.

Appears that the dev. for Theme & Font Size Changer is not inclined to update that ad-on, although a number of users have offered to make contributions to him to make his time financially worthwhile.....
