How do I increase the width Thunderbird scrollbars ?

more options

This is regarding TB 91.13.1 on Windows 11. I know with later versions of TB you can change a setting in Preferences > config editor to make the scrollbar wider. But this doesn't work with TB 91.13.1. In fact you have to add that preference, which I've done, along with several others. So far nothing makes any difference.

I've also added the text as mentioned here but it made no difference. https://support.mozilla.org/en-US/questions/1251403

Any suggestions would be appreciated, Thanks

All I can surmise then, is that maybe the CSS doesn't work with that release.

check that the file is userChrome.css and not userChrome.css.txt - that happens if you have defined suffixes to be hidden.

Mine does not have the .txt extension.

An easy way to check is to look at profile folder to see if it shows a prefs file or a prefs.js file . Click help>troubleshootinginformation' scroll down to 'profile folder' and click 'open folder' look for prefs.js

if found, then I think there still may be an error in the userControl file. to verify, can you post a screenshot of the userChrome.css file? That may help in case the CSS needs adjusting.

Hello

According to my test, apparently, it's not working.

I have a prefs.js file. Here's the userChrome.css screenshot

I tried adding some Preference config entries that didn't exist. IOW the entries from other versions that people said to modify. Nothing made a difference. I know it can be changed in vers 102.15.1 because I tried it. Guess I'll be updating TB.

Thanks for all your help.

Hello

A test.

scrollbar { width: 50px !important; }

And. Go to configuration editor https://support.mozilla.org/en-US/kb/config-editor Enter a search term toolkit.legacyUserProfileCustomizations.stylesheets Double-click on the preference, to set its value to true

And restart Thunderbird.
