Recently I stumbled upon a statement that new Opera 18 does not remember most recently used tabs when switching between them with Ctrl+Tab. In classic Opera, the last version 12.16, pressing Ctrl+Tab switched to the previously used tab: this way it’s easy to switch between the two tabs just like between two applications with Alt+Tab in Windows.
I still use the classic version of Opera, and I didn’t see the change. In Firefox, pressing Ctrl+Tab switches between the tabs in the order they were opened: from the first to the last tab as they appear on the tab panel. But you can change the behavior.
- Open a new tab in Firefox (Ctrl+T).
- Type about:config into the address bar and press Enter.
- Click I'll be careful, I promise!.
- Type ctrl into the Search field above the list of settings.
- Double-click the line with setting browser.ctrlTab.previews.
The value in the Value column would change to true, and Status — to user set.
- Close the tab (Ctrl+W).
Now when you press Ctrl+Tab, Firefox would switch you to the most recently used tab. If you hold Ctrl for a while, you’ll see a window with tab previews; if you press the keys fast enough, the preview window won’t appear and the browser will switch to another tab.
