User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20171206182557 Steps to reproduce: Every day I get (from my workmates) an (plain text) XML report with size between 100kB - 2MB. Actual results: When I click on the mail TB hangs for almost half an hour before it reacts on any input. On small attachments (100kB) the reaction time is ~ 1 min. Expected results: Reaction should be somewhat (linear) depend on the message/attachment size, but not expotentially
Similar sized attachments with different mime types work fine, e.g. ZIP files. In a test mail the attachment was just added (sent from TB to Outlook and then returned back to TB) manually. This has no effect on the hang-up (the daily mail is generated by a tool).
This is bug 736951, which depends on resolution of core bug 197956
