I’ve been a long-time professional user of both Thunderbird and Firefox — going back to the Netscape era — and recent updates have introduced several frustrating regressions that slow down everyday workflow.
1. Thunderbird (macOS 15.7.1, v140.3.1 ESR)
The long-standing ability to hold down the Delete key to continuously remove messages has been disabled.
This was one of Thunderbird’s most practical time-savers when cleaning large folders or reviewing Trash mail.
The new single-tap-only delete behavior makes large-scale cleanup painfully slow.
Please consider restoring a preference in Config Editor to re-enable “continuous delete” for advanced users who need it.
2. Firefox for iOS (v143.2 build 62218)
Tab titles now appear below thumbnails, reducing visibility.
Drag-reordering is inconsistent: dragging upward can suddenly drop a tab to the bottom of the list.
A simple “scroll-to-top” arrow at the bottom of the tab list would greatly improve navigation.
These changes may seem minor, but they directly affect speed, precision, and usability for serious long-term users.
Re-introducing small but powerful workflow options would make a big difference.
(Note: This post includes cross-product feedback so that both Thunderbird and Firefox mobile teams are aware of similar usability regressions.)
THANKS IN ADVANCE
