2018423 - Buttons ( minimize, miximize, close) are missing after first FF start

Status: RESOLVED DUPLICATE of bug 2010552

(Core :: Widget: Win32, defect)

Description

[Stephan]

Attachment: ff_control.JPG

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:147.0) Gecko/20100101 Firefox/147.0

Steps to reproduce:

Turn on the pc ( Win10 latest updates) and start Firefox...

Actual results:

Most time ( 80-90 %) when I start Firefox the Buttons in the upper right corner for minimizing , maximizing or closing are not visible( Picture 1. ), as long as I minimize Firefoy by clicking the FF Symbol at the taskbar.
After one time Mini- maximizing it everything is fine (Picture 2. ) no matter how often i minimize or bring it back again.
This behaviour is since ca. 2 month, and was also within the last two FF versions. A complet uninstall and fresh installation of Firefox didn't help, neither disabling the two Addons ( i dont care about cookies & uBlock)

Expected results:

I would be happy about any helping hand with this Problem.
Anything more I can provide please let me know.

Thank you

Hello, thank you for the bug report!

Unfortunately I could not reproduce your issue. Would you be so kind as to answer a few questions so we can investigate this further?

• Can you please provide more details? Are there any other settings needed to reproduce this issue? Are you using High Contrast Mode?
• Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
• Does this issue happen with latest nightly? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/

Moving the Component to 'General'. Please change if there's a better fit, thank you.

I think this is a duplicate of bug 2010302, but answers to comment 1 are still helpful!

Actually closer to bug 2010552, which was resolved as a duplicate of the earlier duplicate, but there is some debate over whether they are the same (because one involves the Windows titlebar and the other doesn't). Switching the bug reference.

Sorry for my late reply, had some problems with the Internet connection.
@Ardelean Oana
About your first question, no I'm not using the High Contrast Mode. I've tried your second hint ( new Profile ) and then the Problem "was" gone, but then the look was totaly different. ( Bars having different hights, TAB Bar over the Adress Bar...)

How can I attach a Picture to my reply??¿¿??

After that I rememberd that long tima ago I created a userChrome.css file to get the Tab Bar under the Adress Bar including the following Text, which worked fine for the last xx Month/years

`#TabsToolbar {
position: absolute ;
display: block;
top: 85px !important; /Abstand nach oben/
width: 100% !important;
}

.tabbrowser-tab {
margin-top: 2px !important;
max-height: 35px !important;
}

#tabs-newtab-button {
padding-top: 5px !important;
padding-bottom: 0px !important;
}

#tabbrowser-tabs {
width: 100vw !important;
}

#main-window:not([chromehidden*="toolbar"]) #navigator-toolbox {
padding-bottom: 37px !important;
}

#navigator-toolbox:not([tabs-hidden])

#nav-bar
:is(.titlebar-buttonbox-container) {
display: flex !important;
}`

After doing some search on Google and in different Forums I ended up today with a new Version for keeping the TAB Bar under the Adress with the following code:
#TabsToolbar { position: absolute; display: block; bottom: 0; width: 100vw; background-clip: padding-box; color: var(--toolbar-color); } #tabbrowser-tabs { width: 100vw; } #navigator-toolbox { position: relative; padding-bottom: calc( var(--tab-min-height) + 8px ); } #main-window[tabsintitlebar][sizemode="maximized"]:not([inDOMFullscreen="true"]) #titlebar { height: 36px; } .titlebar-buttonbox-container { position: fixed; right: 0; visibility: visible; display: block; } #TabsToolbar .titlebar-buttonbox-container, #TabsToolbar #window-controls { display: none; }
For me on my Screen both are doing the same Job, but with the new Version I didn`t have the mentioned Problems the whole Morning no matter how often I opened/closed FF.
Maybe you can undrestand the code and see if there were changes in one of the last FF-Versions which can cause the Problem.
No matter how thank you all for your help. :-)
