Thunderbird Zoom problem

Making moves

Am currently using Thunderbird on v115.3.1.  For a couple of versions at least, attempting to zoom the text of an incoming mail using Ctrl/+ does nothing until I zoom once using the View menu, then Ctrl/+ works for subsequent zooms.


Edit:  I have found that the Ctrl/+ will start working just by opening and closing the View menu without even selecting Zoom from there.

I'm running v115.4.1 for Linux and have the same problem. Tried what you mentioned in your edit (just clicking on view menu) and it starts working, too. Ctrl+scroll works and after doing that, the keyboard shortcut starts working also.

I have also raised this on Bugzilla, but there has been no response so far.

This issue is broken on 15.5 as well. A real Irritant. Thanks for reporting this.

Making moves

A real hassle. I have many e-mails that I cant read unless I blow them up, which means I have to press many keys to do it like CTRL-V-Z then Enter, then CTRL-+ repeatedly for the right zoom. The next email defaults back to the original zoom to have to do all over again. It's bad when you've got 50 emails to open.

I'm on Fedora Linux 39 using Thunderbird 115.6.0 as a Flatpak and this issue is still present. The fix of just clicking on the View menu and then doing Ctrl/+ works, but what is working for sure is holding Ctrl while moving the mouse wheel up/down for zooming, so this is an alternate shortcut you could use. I'm on a touchpad so this is a little less convenient but still works.

Works also using Ubuntu 20.04. Thanks so much for posting that. I was just about to dump Thunderbird due to the broken ZOOM function and the frustration it causes. I may stick around and see if it is ever going to be fixed now that your workaround functions.

On my Windows 11 partition with the same version of Thunderbird Ctrl/+ also does not work, and you still need to hold Ctrl while scrolling. This is probably just a Thunderbird issue and not OS-related.
