Luckily Thunderbird is a really expandable client, so a possible solution would be to edit the userContent.css
file which allows you to specify custom CSS rules for messages.
Try the following steps:
- Go to your Thunderbird profile folder (follow the instructions in the page and select your OS). It should look like this (obviously with a bunch of other files):
- Create the
chrome
directory if it does not exist. - Create inside the
chrome
folder a file nameduserContent.css
as a plain text file (be sure to show file extensions if necessary, otherwise you may end up with auserContent.css.txt
file and it is not what we want) Edit the file with any text editor (notepad should work too), and put the following line in it:
* { word-wrap: break-word; }
- Restart Thunderbird and you should be good to go.
This is a test I did locally, before and after applying the rule:
As you can see the text is not wrapped and there's the scrollbar you are talking about.
Now, with the userContent.css
applied, the text is wrapped automatically (thus there are no scrollbars) and this looks like it's what you wanted.
