Firefox コミュニティフォーラム

I have Firefox configured with auto-expanding vertical tabs. Sometimes, when the mouse cursor leaves the Firefox window through the same border where the tab bar is located, the tab bar expands and stays in that state until the cursor returns to the Firefox window. This is especially annoying with two displays; if the cursor hovers over the tab bar right before moving to the second display, the tab bar remains expanded, overlapping part of the browser content.

I had an issue with v141 showing only pinned tabs but got that straightened out with a change to my userchrome.css file.

I noticed that double clicking the tab bar does nothing, but specifically, does not open a new tab.

browser.tabs.drawInTitlebar in about:config is set to true title bar in customization is checked

I have disabled a Tab Mix extension and confirmed that all pertinent about:config settings were set correctly but still I cannot double click to open a new tab.

Please advise. Thank you!

With latest Firefox Desktop 141.0 I found an odd behavior of pinned tabs which now are scrolling left and disappear from view site in a top tab bar.

• Is this a new feature or bug?
• Any setting to prevent them from scrolling?
• How to prevent this from happen?

Hi Mozilla Support,

Platform: MacBook Pro, Mac OS 12.7.6 Browser: Firefox 141.0 Tab Session Manager installed and configured

I had approx 150 tabs open. Closed Firefox in an orderly controlled manner.. Restarted machine.. Opened Firefox.. It failed to restore my tabs after restarting.

Selected from Firefox menu -> History -> Recently Closed Tabs (greyed out). Tried everything, but cannot get the tabs back. I shall be grateful for any help and advice.

Thanks and kind regards.

I don't know what's changed, but now whenever I press Ctrl + Left or Ctrl + Right, the next tap opens. How to disable these keyboard shortcuts? This happens while text editing and it's a problem.

Thanks
