Version

129.0.6668.58

Have you tested that this is not an upstream issue or an issue with your configuration?

• I have tried reproducing this issue in Chrome and it could not be reproduced there
• I have tried reproducing this issue in vanilla Chromium and it could not be reproduced there
• I have tried reproducing this issue in ungoogled-chromium with a new and empty profile using --user-data-dir command line argument and it could not be reproduced there

Description

I click the Reading mode menu button and nothing happens.

How to Reproduce?

1. Go to a website with articles that browser reading modes generally support. (I used this URL.)
2. Follow the instructions to use Reading mode by clicking the three-dots menu > More tools > Reading mode.
3. See error (nothing happens).

Actual behaviour

Nothing happens. (Tried on multiple sites with articles that Firefox's reading mode supports.)

Expected behaviour

Reading mode opens.

Relevant log output

No response

Additional context

Updated via Chromium Update Notifier extension

Can confirm the same behavior on 129.0.6668.70 version, Linux, Slackware 15 64bit.

Did it work before? At which version did it stop working?

I'm sure it worked on 106.0.5249.119, but that's a very long time ago :')

This was the first time I've tried reading mode in Unloogled Chromium, so no clue sorry 😅

On 126.0.6478.61 version would open Reading Mode window, but will not display anything. On 128.x and 129.x won't even open Reading Mode window.

I think it is being removed here:

ungoogled-chromium/patches/core/ungoogled-chromium/fix-building-with-prunned-binaries.patch

Lines 695 to 702 in 477f402

	- // Install ReadAnythingAppController on render frames with the Read Anything
	- // url, which is chrome-untrusted. ReadAnythingAppController installs v8
	- // bindings in the chrome.readingMode namespace which are consumed by
	- // read_anything/app.ts, the resource of the Read Anything WebUI.
	- if (render_frame()->GetWebFrame()->GetDocument().Url() ==
	- chrome::kChromeUIUntrustedReadAnythingSidePanelURL) {
	- ReadAnythingAppController::Install(render_frame());
	- }

as it was depending on some of the pruned binaries from screen-ai.

Unfortunately I'm very limited with Internet access and computing power right now, so cannot tell if/when I could investigate further :(

I just realised that there's a separate Windows repository, where someone also opened a ticket: ungoogled-software/ungoogled-chromium-windows#373
