Why doesn't Ctrl + F5 work in Firefox?

Question

I'm using Xubuntu 11.04, and with a Windows XP in my VirtualBox. Both have latest Firefox 4 installed. But inside my Ubuntu, Ctrl+F5 never works, and because I don't know what else I could do to force refreshing a page, I have to copy the link and paste them into my Windows XP to get the newest results.

Is there a way that I could solve this?

Thank you very much if this problem could get a solution.

EDIT: Even though Ctrl+F5 doesn't work, I just found it can also be triggered by Ctrl+Shift+R too.

Full shortcuts reference here.

Solution 1

_{Moving the comment from Grzegorz into a Community-wiki answer.}

This problem occurs because Xubuntu uses Ctrl+F5 to switch into fifth workspace (if you don't have as much workspaces, then simply nothing happens), in fact whole F1-F12 range is reserved.

There are two possible solutions:

• Redefine (clear) shorcut in Xubuntu (via Settings→Settings Manager→Window Manager→Keyboard) or
• Use alternative i.e. Ctrl+Shift+R.

Solution 2

You must press Ctrl+Shift+R to overwrite the cache in Xubuntu

Turned out to be my exact problem. (Just switched to xfce desktop from MATE to facilitate better response on my VM).

CTRL+F5 doesn't use cached files.

there are only several shortcuts in my system and none of them are CTRL+F5, is there a way to set firefox's shortcuts?

Had the same problem using Lubuntu 20.04 with LXQT. The solution is largely the same. I truly don't remember this happening with my old Lbuntu setups with plain LXDE.
