Enlarge the text of the selected message

Post by steve48 »

The recent upgrade to 68.3.1 changed something I'd like to change back :)

My screen has a list of folders on the left, a list of messages on the upper right and the text of the selected message on the lower right.

After the upgrade, the font of the text in the lower right pane is a lot smaller. How can I configure Thunderbird to make the font of the selected email larger?

Thanks.

Is the too small problem with all emails or just some emails?

Just some of them, I should have pointed that out in my original posting.

Roughly half of them are "normal" while the rest are "too small".

I believe that prior to the recent Thunderbird revision I occasionally saw the "too small" problem. It is much more frequent after the revision, that's why I linked it to 68.3.1.

Thanks.

Go to tools options display formatting advanced and select 17 for serif fonts and 14 for sans serif fonts. Set minimum font size to none. Note. You have to do this for both Latin and other writing systems. Then clise and restart thunderbird.

I see how to set font size for Proportional and Monospace fonts. But neither Serif nor Sans-Serif have the Size fields to the right of them like the Proportional and Monospace fonts have. So how do I set the font size for Serif and Sans-Serif without a Size field available?

They are irrelevant to what you want. They will change when the following is changed.

What is important is that Fonts for box at the top and setting fonts for both Latin and Other Writing Systems.

Also, uncheck that Allow messages to use other fonts box - it doesn't mention that allowance includes any size font they want, even tiny ones.

17 for proportional and 14 for monospace. Set that for both Latin and Other writing systems. None for minimum font size. Sorry for the confusion. My bad. Let us know if that doesn't fix the problem. Try just these changes first. If they don't work then in addition to the above try Frank's recommendation to check or uncheck as necessary to "Allow messages to use other fonts".

I have configured Thunderbird per the advice above. I do not see any difference in the incoming emails. Some are "normal" while others are "too small". I haven't counted them but it is about a 50-50 split.

Create a text file named userContent.css (note name is case sensitive). Put this in the userContent.css file.

/* Put this in Thunderbird userContent.css file */

body {
font-size: 100% !important;
}

.moz-text-html .MsoNormal {
font-size: 120% !important;
}

.moz-text-html .MsoListParagraph {
font-size: 120% !important;
line-height 1.4 !important;
}

.moz-text-html {
font-size: 120% !important;
}

pre, code, kbd, samp, tt {
font-family: monospace, monospace !important;
font-size: 120% !important;
}

After you have the userContent.css file created and filled in then place the userContent.css file in the chrome directory under your thunderbird profile directory. If you don't have a chrome directory under your profile directory, create one. Note the name is case sensitive. The name is " chrome " .

This is mine:

You must restart thunderbird for the changes to take effect. You can play with the percentages and with deleting entirely each code subsection. Don't eliminate the Body section or change it from 100%. The .moz-text-html section effects all html messages and the pre, code, kbd, samp, tt section effects all plain text monospace messages.

You may also need to set the following preference by clicking tools options advanced and then selecting the config editor:

Unlock custom CSS usage in Thunderbird 68 and newer

Settings/Options > Advanced > General > Config Editor...
toolkit.legacyUserProfileCustomizations.stylesheets > set to true.

I installed the userContent.css in the chrome directory. The toolkit.legacyUserProfileCustomizations.stylesheets was already set to true. I have little grasp of what it all means, I am not a computer guru by any means.

It has been several days since I made the changes. I have not done a detailed census of incoming emails, but it *seems* that there are fewer "too small" fonts. They haven't gone away, there are still a significant number of them. But fewer I think.

Appreciate the help.

Next time you get a couple of too small emails, open them in a separate tab and then click view > source in the menus. Copy the source code for the too small messages and paste it into a post here.

Also under tools > options > display > formatting > advanced did you set 17 for proportional and 14 for monospace. Set that for both Latin and Other writing systems. None for minimum font size.

Confirmed that proportional is 17, monospace is 14. For both Latin and Other.

Here is the source code for a "too small" email received today:

There are no example configuration files for DXP.

The serial ports in DXP are *hardware* ports - applications should
be configured exactly as if using native hardware ports (i.e., there
are no virtual ports to configure).

Re: Enlarge the text of the selected message

In the userContent.css file try the following:

Change the percentages (other than the percentage for the "body" section at the top which should stay at 100%) from 120% to 160%, then tell me which parts of the above message got too big, if any, and which didn't change, if any. Restart TB for the changes to take effect.

Also, let me know if you know how to use developer tools and can tell me what the name of the paragraph formatting is for the normal sized text and too small sized text. Finally, is the too small sized text plain monospaced text or is it html text or both types?

FYI,

/* Put this in Thunderbird userContent.css file */

/* The following should be left as is */
body {
font-size: 100% !important;
}

/* The following affects email messages formatted by Microsoft Office/Office 365 */
.moz-text-html .MsoNormal {
font-size: 120% !important;
}

.moz-text-html .MsoListParagraph {
font-size: 120% !important;
line-height 1.4 !important;
}

/* The following affects ALL html formatted messages and might need to be deleted for many users */
.moz-text-html {
font-size: 120% !important;
}

/* The following affects all plain text monospaced messages */
pre, code, kbd, samp, tt {
font-family: monospace, monospace !important;
font-size: 120% !important;
}

The above css setting could also be altered to affect not just the size of the text but also the font-family of the text and the colors of the text.
