I tried to reproduce the issue when...
Description
Viewing the filter lists contents in the uBO interface, I've found that the "header" of the "RU AdList: Counters" filter list ("cntblock.txt" file), instead of a specific modification date, contains just the "%timestamp%" string.
Primarily, I've opened the issue in the corresponding filter list repo, but one of its maintainers responded, that it is a problem on an uBO side, something with list update automation.
The wrong behavior looks like this:
[Adblock Plus 2.0]
! Title: RU AdList: Counters
! Last modified: %timestamp% <<<<<< this
! Expires: 2 days (фильтр обновляется автоматически каждые 2 дня)
The expected behavior is for the variable's name to be replaced by its contents, something like the example below (it is from the main "RU AdList" filter list, "RuAdList-uBO.txt" file):
[uBlock Origin 1.0]
! Title: RU AdList for uBO only
! Expires: 4 days
! Last modified: Mon, 25 May 2026 04:47:43 +0000 <<<<<< this
This problem is started from the moment when "RU AdList: Counters" ("cntblock.txt") was added to uBO's default filters :)
Maybe, this will come in handy :)
A specific URL where the issue occurs.
moz-extension://<some_uBO_UUID>/dashboard.html#3p-filters.html
moz-extension://<some_uBO_UUID>/asset-viewer.html?url=RUS-1
Steps to Reproduce
- Open uBO dashboard.
- Go to filter list page.
- Scroll down to the regional filters.
- Find "RU AdList: Counters" there, and tick it's checkbox.
- Press "Apply changes" button, which is floating at the upper part of the uBO interface.
- Wait till the "RU AdList: Counters" filter list will be downloaded by uBO.
- Press "show contents" button (which looks like an eye) in the end of the "RU AdList: Counters" string in the uBO interface - new tab will open, showing the contents of the filter list.
- Check the header strings of the list in this new tab, find the "! Last modified:" one - it will have the "%timestamp%" after it.
Expected behavior
Instead of the "! Last modified: %timestamp%", there should be the actual date (something like "! Last modified: 2026-05-26, 22:54:15").
