I’m using Thunderbird 115.13.0 (32bit, ESR) on Windows 10 and have had problems with the Quick Filter Toolbar for quite some time now. Taking a picture from the Mozilla Support page, this is how the Toolbar should look like:

Now, this is how my toolbar is displayed:

As you can see, the “Filter message by: Sender, …” beneath the search field is not showing up anymore and this is absolutely driving me crazy. Even worse, one of the not showing filters is seemingly checked, which renders the toolbar completely useless for me at present.

If you have any idea what is causing this and how to fix it, you would absolutely make my day because this is one of the main ways of me searching my e-mails.

Thanks

Sebastian
