How to suggest improvements?

Firefox Solução de problemas

Hi!

How/where can I suggest new or improved features for Firefox?

The improvement I am think of is in History -> Recently closed windows. Here it is only possible to re-open maximum 3 windows, although I had closed 6 windows within a few minutes. This is very annoying! I lost approximately 24 tabs this way!

Best regards, H.R. (Using Firefox 22 on Windows 7, 64-bit)

There are several ways to suggest improvements. The simplest is to use

Help > Submit Feedback

A more complicated way is to file a "bug" in the bug tracking system, as a request for enhancement.

A third way is to subscribe to one of Mozilla's many discussion lists, whichever seems most relevant. Many have their archives online, such as the "usability" list: https://lists.mozilla.org/listinfo/dev-usability

However, in the short run, there actually is a hidden setting to increase the number of closed windows and tabs Firefox lets you access.

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste session and pause while the list is filtered

(3) Double-click browser.sessionstore.max_windows_undo and set the number of windows you can re-open. (I chose 10, because I tend to use news windows quite a bit.)

(4) Double-click browser.sessionstore.max_tabs_undo and set the number of tabs you can re-open in the current window.

Bear in mind that session information is saved to disk every 15 seconds (by default), so remembering more may slightly increase the background workload.
