Prevent Accidental Close on Firefox Tab with PermaTabs Mod
Sometimes, having too many Firefox tabs opened at once can lead to an accidental close. You can restore the tab easily by making use of the history recording feature, but if you often accidentally close tabs this will soon become an annoying problem. To prevent an accidental close on a Firefox tab, you can install Permatabs Mod.
Permatabs Mod is a Firefox extension that protects selected tabs so you cannot close them. Press the hotkey and the current tab will be made permanent. Open a new tab, press the hotkey again and the tab will also be protected. Even if you accidentally select “close other tabs” the protected tabs will not be closed.
Prevent Firefox Tab Accidental Close with Permatabs Mod:


“Turn tabs of your choice into permanent tabs. PermaTabs can’t be closed accidentally no matter what you click (even actions like “Close other tabs” will not affect them) and will stick around between sessions.”
Install Permatabs Mod from Firefox extension gallery to prevent accidental close on Firefox tabs
Files that are compressed within zip or rar format can be downloaded faster, but the disadvantage from such an archive is that we cannot view the content before we download it. To view the content, we have to download the archive first and then open it with a zip or rar opener like Winrar or Winzip. What if you find later that the files you’re looking for aren’t within the archive that you have downloaded? If you just want to get a file with only 10 Kb in size from the archive, do you really have to download the whole archive to be able to get it?
The close button is indeed available for each Firefox tab that you only need to click it once to close the tab. If you think it isn’t fast enough, then the combination of Ctrl + W as the keyboard shortcut to close tab can be used instead. But some users think these two aren’t enough yet, so a Firefox extension called Close Tab by Double Click is created.
