--- Comment #6 from null <n...@lab12.net> --- I agree the code generated by some mail apps (GMX app in particular) is often problematic, sadly some senders insist on using them. However, it leads to KMail displaying the whole multi-paragraph quote without any linebreaks whatsoever, which is not what was intended by the sender and which is very hard to read. As you can see from the screenshot, Thunderbird is able to display the mail just fine. I just retested with Thunderbird 91.2, it still works there. If "t.html" does not work in Firefox, it means Thunderbird (which also uses the Gecko engine) might have added a workaround, e.g. transforming "blockquote" to "pre" (while making sure to copy over other styling such as the use of a non-monospace font). It would be great if KMail was able to reach the same level of compatibility, even for "broken" mails. -- You are receiving this mail because: You are watching all bug changes.
