Opening an additional new window opens up my last session?

more options

If i open an additional window (new window) what opens up is every tab from my last session. I like to have my session restored when I open firefox again, but I don't want it to restore in every window I open up, any ideas?

A new window opens with the home page(s).

You can check the home page setting:

Firefox supports multiple home pages separated by '|' (pipe) symbols.


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Rename (or delete) the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

correct, case closed.

This is an oversight by the developers of the latest FireFox revision: a great shame, as the overall feel of the browser has patently been improved.

Xabolcs has come up with a nice fudging idea; if it were to work; but sadly it doesn't for me....

As mentioned, the latest version of FireFox (May'14) now opens one's "homepage" instead of a new blank window. As my "homepage" is almost a dozen tabs; this is worse than useless. It's like starting FireFox again; and then having to close a whole string of unwanted tabs!

To compound my frustration, the "move to a new window" option disappeared on another recent FireFox "upgrade"; but I managed to get round that by copying an url from a tab, then opening a new blank window, to paste the url into.

So, is there any possible way to open a new window in this latest version of FireFox?

I just want to be able to open a new FireFox window; and I'd be happy with it being either blank, or duplicating the url of a currently-showing tab. But preferably both options should be available.

This would allow view of one trimmed-size webpage in front of another one, showing in a selected tab in my normal-use multi-tab window: useful when comparing complex images, for example.

Meanwhile, if the developers are watching out for feedback..................................... please sort this, by putting back at least one of these:

"open a new blank window" or "move page to new window"

After all, I do NOT want to have to use Gugl-Krohm!

Firefox has always opened a new window the the home page(s), so that is not a recent change.

Easiest to open a blank window is to create a bookmark with the location set to about:blank on the Bookmarks Toolbar and hold down the shift key and left-click this bookmark.

You can tear off a tab by dragging the tab slightly down in the browser window and that tab will be opened in a new window.
This is the same as the "Move to New Window" item that you have in the right-click context menu of a tab on the Tab bar.

I'll concede that I may be remembering the "open new window" (drop-down menu) option; giving me a single tabbed window; from the days before I had a multiple-tab home-page.

But the bookmarked blank window idea is inconveniently complicated: at my age, it is difficult to remember new command sequences: even if I thought that bookmark suggestion would save any appreciable time....

Also I can't get the "dragging the tab slightly down" suggestion to work at all: only some rearrangement of the tabs' order, left-to-right.

Thirdly, you refer to a "Move to New Window" item, claiming it is there in the right-click menu from a tab. This illustrates that you missed the point of my complaint: it ain't there!

There is NO "move to new window" or "open in new window" option

So my question remains: why-oh-why did the developers decide to drop this "open (current page) in a new window"????? It was working fine before: so why did they "fix" it???

We mere mortals need a drop-down menu option that's simple: not some clever shortcut, with-holding a shift key whilst balancing our three braincells on a slippy pogo stick!
