Hi jpitkow, Firefox doesn't provide a way to remove right-click context menu entries, except in a very few cases.

You can use custom style rules to modify menus. This involves creating a userChrome.css file, putting it in the right folder, and setting Firefox to look for it. But perhaps most importantly, it requires finding the correct selector or selectors to identify the items you want to remove from the menu. Is it just the one? Would it be better to remove it and have the next one slide up, or disable it somehow (if it can be disabled)?

I'm having this problem as well. For me, it's not a matter of removing a menu option - it's disabling this feature entirely. If I close one tab I only want that tab to close. The default behavior for Firefox is to close tabs to the right. This is not the desired behavior.

No, that's not normal. How are you closing the tab? For example:

• click the "X" close button on the tab
• right-click the tab > Close Tab
• Ctrl+W (Mac: Command+w)
• some other method

Firefox allows multi-selecting tabs. In that case, when you right-click, you'll notice that the menu has changed from Close Tab to Close Tabs (plural). Ctrl+w will also close all selected tabs.

Multi-selecting tabs is similar to multi-selecting files from Windows/File Explorer. With one tab (file) selected, you can either:

• add a tab (file) to the selection by Ctrl+clicking that tab (file)
• add a range of tabs (files) to the selection by Shift+clicking the last tab (file) in the range

Firefox will show a light blue line on the top of all tabs in the selection.

Could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?
