Floating Firefox Extension's Windows

General
1

Regular rules do not work with Firefox extensions because Firefox sets the title of the window after spawning it.

The workaround for this is using Hyprland’s events:

hl.on("window.title", function(w)
    if string.find(w.title, "Extension: (AliasVault)", nil, true ) then
        local monitor = hl.get_active_monitor()
        if monitor == nil then
            return
        end

        local win_size = {
            width = 500,
            height = 530
        }
        --[[ local win_pos = {
            x = monitor.width * 0.5 - win_size.width * 0.5,
            y = monitor.height * 0.5 - win_size.height * 0.5
        } --]]

        hl.dispatch(
            hl.dsp.window.float({
                action = "enable",
                window = w
            })
        )
        hl.dispatch(
            hl.dsp.window.resize({
                x = win_size.width,
                y = win_size.height,
                relative = false,
                window = w
            })
        )
        --[[ hl.dispatch(
            hl.dsp.window.move({
                x = win_pos.x,
                y = win_pos.y,
                relative = false,
                window = w
            })
        ) --]]
        hl.dispatch(hl.dsp.window.center({ window = w }))
    end
end)

You can use the commented section if you would like the window somewhere specific.

That is all, cheers.

After trying unsuccessfully various methods including timers to script a solution to:

I applied your function and it no workie for the noscript window.

This is just a curiosity as I don’t use Firefox for other than testing.

That is odd, I have tested this with Bitwarden, AliasVault and some others and all of them worked. Does it work for other windows on your side?

NoScript is certainly more finicky.

I ended up writing a rule that tames NoScript.

hl.on("window.open", function(w)
    if w.class ~= "firefox" then return end
    if w.initial_title ~= "Mozilla Firefox" then return end

    local ff_windows = hl.get_windows({ class = "firefox" })
    if #ff_windows <= 1 then return end

    hl.dispatch(hl.dsp.window.float({ action = "set", window = w }))

    local sub
    sub = hl.on("window.title", function(tw)
        if tw.address ~= w.address then return end
        if tw.title == ""
            or tw.title == "Mozilla Firefox"
            or tw.title == "about:blank"
            or tw.title:match("^about:.*Mozilla Firefox$") then return end

        sub:remove()

        if tw.title:match("^Extension: %(NoScript%)") then
            hl.dispatch(hl.dsp.window.resize({ x = 800, y = 600, window = tw }))
            hl.dispatch(hl.dsp.window.center({ window = tw }))
            hl.dispatch(hl.dsp.focus({ window = tw }))
        else
            hl.dispatch(hl.dsp.window.float({ action = "unset", window = tw }))
        end
    end)
end)
