Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT an issue with YouTube, Facebook or Twitch.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

By following the Thunderbird "Get the Add-On" button on https://github.com/gorhill/uBlock/blob/master/README.md, which indeed leads to the correct destination, it appears the uBO version on that page is listed as 1.49.2 and is shown as last updated in April. https://github.com/gorhill/uBlock/releases shows that Thunderbird uBO builds continue to be built, so the Add-ons page would presumably need an update to reflect that.

I am all too aware that Mozilla's work on Thunderbird has been very messy (potentially affecting their add-on store as well), and that it's as such anyone's guess how fast their approval process for 1.53.0 or later would be, but I feel it's worth a try to submit an update.

A specific URL where the issue occurs.

https://addons.thunderbird.net/en-gb/thunderbird/addon/ublock-origin/

Steps to Reproduce

1. Visit https://addons.thunderbird.net/en-gb/thunderbird/addon/ublock-origin/, which is the official page on Thunderbird's Add-Ons store for uBO.
2. See that the version number is listed as 1.49.2, and that the "Last Updated" info is shown as 28 April 2023.

3. Installing uBO directly into Thunderbird from visiting that page within Thunderbird itself, and going to uBO's settings → About, shows it's indeed v1.49.2.

Expected behavior

uBO on Thunderbird's Add-Ons subdomain gets updated at least once every 2 or 3 months or so.

Actual behavior

uBO on Thunderbird's Add-Ons subdomain has not been updated for around 6 months or so at the time of writing.
