Hello Korwin,

Thank you for your feedback.

"Tooltips are not displayed..."
Tooltips in the Options page are designed to appear on hover, not on click. I tested this on Win10 with Firefox versions 140.0b1, 139.0, and 141.0a1, and I wasn't able to reproduce this issue. Tooltips were displayed as expected.
The only two scenarios I can think of are if the browser window is not currently focused while hovering or if it is of a disabled setting. For instance, if the setting "Use custom style sheet for Feed Preview" is off, the tooltip for "CSS source code" will not be shown.


"No language selection..."
The extension isn't multilingual at this time. Sorry, but it's on my to-do list.


"No 24-hour time format..."
If you're referring to the inconsistency between the format in the "Every Day at..." dialog and the format shown in the dropdown, then you're absolutely correct. I will fix it.


"Feeds (in my case, there..."
I chose to store feeds in the browser's bookmarks to leverage Firefox's built-in Sync feature. This enables the extension to provide feed synchronization across multiple devices without relying on an external server.
While this approach does clutter the bookmarks searches results, it provides synchronization without sharing your data with a third-party.


Thank you for taking the time to provide feedback.
