Dead zone on Firefox tab-bar in Linux Mint 19.2, Cinnamon

[catscratchedme]

Expected behavior: Usually, if you drag your mouse to the very top of the maximized Firefox window, the tabs and new tab button are clickable.

Bug behavior:
When using the Windows-10-Dark-3.0-dark window borders, you cannot select tabs or click the new tab button when your mouse is all the way at the top of the screen. Instead, you grab and drag the Firefox window itself.

This bug happens when:
The Firefox title bar is removed (Options > Customize > uncheck "Title bar")
The Firefox window is maximized.
Window borders for Windows-10-Dark-3.0-dark are selected

there is a 1px top border when maximized, which probably causes the bug. I'll have a look at it as soon as possible but it should be easy to patch

[Elbullazul]

in metacity-1/metacity-theme-3.xml, try replacing

<frame_geometry name="max" title_scale="medium" parent="normal" rounded_top_left="false" rounded_top_right="false">
	<distance name="left_width" value="0" />
	<distance name="right_width" value="0" />
	<distance name="left_titlebar_edge" value="2"/>
	<distance name="right_titlebar_edge" value="2"/>
	<distance name="title_vertical_pad" value="2"/> <!--
							This needs to be 1 less then the
							title_vertical_pad on normal state
							or you'll have bigger buttons		-->
	<distance name="bottom_height" value="1" />
</frame_geometry>

with

<frame_geometry name="max" title_scale="medium" parent="normal" rounded_top_left="false" rounded_top_right="false">
	<distance name="left_width" value="0" />
	<distance name="right_width" value="0" />
	<distance name="left_titlebar_edge" value="2"/>
	<distance name="right_titlebar_edge" value="2"/>
	<distance name="title_vertical_pad" value="2"/> <!--
							This needs to be 1 less then the
							title_vertical_pad on normal state
							or you'll have bigger buttons		-->
	<distance name="bottom_height" value="1" />
	<border name="button_border" left="0" right="0" top="0" bottom="0"/>
</frame_geometry>

@Elbullazul Fixed it for me. Currently using Cinnamon v4.4.8.

[catscratchedme]

That fix is not working for me.

Linux Mint v19.3
Firefox v73.0
Cinnamon v4.4.8

@vroop do you have the client-side titlebar enabled?

in settings>customize, on the botttom, is the titlebar checkbox checked?

[leogx9r]

And this broke again. Also using v73 of Firefox.

FTR, @Elbullazul I do have the title bar checkbox selected.

[Elbullazul]

@leogx9r if you have CSD enabled, then yes, it won't work since it's a GTK headerbar and not the metacity titlebar. Try unchecking it and restarting

@Elbullazul

do you have the client-side titlebar enabled?

I'm not sure what this means, sorry :(

in settings>customize, on the botttom, is the titlebar checkbox checked?

Yes, I have the Firefox titlebar checkbox unchecked.

My intention is to have the Firefox tabs on the top, so I can throw my mouse up to the edge of the screen and select tabs without concentrating on aim.

[Elbullazul]

client-side titlebars (CSD) are window borders drawn by the app itself, instead of the window manager (server-side decorations, SSD).

ex.

left is CSD, right is SSD

can you post a screenshot of the problem? I can't say for sure which one is enabled when the toggle is unchecked

[SakiiCode]

Same problem here

How it works now when maximized (clicking doesn't change tabs rather wants to move the window):

How it should work:

I have the title bar disabled

[catscratchedme]

The screenshots SakiiCode posted describe my situation as well.

Firefox 140 (ESR) has completely deleted any and all GTK styling from Firefox (barring colour palettes), meaning this should no longer be an issue.
