1714186 - Thunderbird font size preferences don't work everywhere

Status: RESOLVED DUPLICATE of bug 570442

(Thunderbird :: Disability Access, defect)

Description

[MarjaE]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

1. I have an astigmatism and can't read very small text on glowing screens.

Actual results:

2. I have tried using the Preferences > Language & Appearance to set a larger font size. I think this affects the Message Pane, but this doesn't affect the rest of the interface, leaving folder lists and message lists unreadable.

3. Standard advice is to use an add-on to fix this, but it periodically fails.

4. My current solution is to use userChrome.css to fix this, but it requires separate css for each part of the interface. When I run into a new section, such as add-on descriptions, I can't read them until I find a new css fix.

Expected results:

Preferences > Language & Appearance font preferences should work everywhere.

This was closed as a duplicate of bug 570442

Which was closed as a duplicate of bug 1715364

Which relies on finding and using a setting in the preferences, which aren't readable because of this bug.

MarjaE,
With the version 115 front end redesign, does this issue still reproduce?
I tested with beta version 118 on Mac, where zoom, density and font size all work.

The main preferences, under Thunderbird > Preferences, do not affect these. The other corner menu preferences, if you know where to find them, do affect these. Neither affects about:config.

Thanks so much for reporting this bug and sending updates. I've opened bug 1854607 to address comment #4.

Our policy is to open new bugs rather than reopen older bugs when a name change and change of scope is needed for the older bug. It sounds like the older bugs did not address fully what you need. Let's address that in bug 1854607.

There have been significant updates in 115 to improve the ability to adjust the font size throughout the application.

You can reach the font size settings in two locations:

• From the application menu, you can go to View > Font Size and Increase Font Size from there.
• From the Thunderbird menu, which is the upper right icon of three parallel lines. Next to font size, select the plus icon to increase the font size. This icon is in the upper right for left to right reading preferences and upper left for right to left.
