Back button unblocks YouTube videos blocked by a keyword

[Anton-V-K]

With default settings the rules to block pages by keyword are usually ignored when the Back button is pressed on the blocked page.

Scenario:

1. Block by keyword (let it be ~roblox, don't forget about the first entry, which is *) + All Day.
2. Go to a page where the keyword is present (let it be https://www.youtube.com/watch?v=-em-iNtwvH4 or you can find other videos via search) => the page is blocked (OK).
3. Press the Back button => the page is unblocked (BUG), and if you open same video in other tab it won't be blocked.

Workaround: enable the option Immediately block pages on these sites once blocking conditions are met, which is . However now the blocking happens when you just type ro in google search, because the suggestions usually contain roblox.

Extension version 1.6
Browser: Supermium 119.0.6045.192 64-bit (should also happen in any modern Chromium-based browser, I use this browser because the extension doesn't work in the last supported version of Chromium - see #338)
OS: Windows 8.1 64-bit

Oops, the initial issue belongs to https://github.com/proginosko/LeechBlockNG-chrome (I had wrong impression that the code was the same for all extensions %).
I can't verify whether the same issue is applicable for the Firefox extension, because it doesn't block by keywords at youtube at all (Firefox 119.0 32-bit / Windows 10 21H1 64-bit / extension's version 1.6).

Are you saying blocking YouTube by keyword doesn't work on Firefox?

I checked the behavior in other environment (Firefox 117.0.1 64-bit / Windows 21H1 64-bit / extension version 1.6), and blocking by keywords seems to work on YouTube, though the Back button cancels the blocking, so the original issue report is applicable to Firefox extension as well.
