I love these icons and have been using them for years. Since 115 though, I couldn't find an easy way to slightly enlarge the toolbar icons, but I did manage that in the userChrome file. But the icon for deleting mail is now different. It's now a bucket with the arrows in the corner that looks like the recycling symbol, instead of the email blue envelope with the red X in the lower right. Is it something in my cache messing it up or a way to change it back to what it was before 115?

This will be fixed in the next version.

I avoided updating Thunderbird past 52 because I hated the flat, uniform looking icons... it just makes it harder to quickly click the right one without thinking about it and hunting through them. I was forced to update though finally to v91 because of Gmail's changes. When I found these icons though, it was the perfect fix. Yes, the newest Tbird update turns the icons off whenever you start Tbird, but just shutting it off and back on quickly fixes it. The folder sort extension I use is still working fine, Manually Sort Folders, so I don't have that problem others have mentioned with it.

In case it helps, the extensions I have are:
Manually sort folders
Open Google Calendar
Phoenity Icons

I am using a theme, but even when using a default theme, the icons don't show on a Thunderbird restart until you turn off the extension and then back on again.

Sorry for the inconvenience, there are a lot of reports like yours so I backed out Phoenity Icons 3.6 and went back to 3.5.
To install Phoenity Icons 3.5 go to the add-on page in the Add-ons Manager, click the Homepage link and install it again from there.

I can't reproduce it here so I do not yet know what causes it.
