I've set a master password for Firefox. When Firefox starts, it strangely opens two separate password request windows. When I type in the master password and hit enter, Firefox opens without problems, but the other password request window stays there. I simply close it but it's annoying. Why are there 2 windows as it's enough to type the password once? I've upgraded Firefox from 3.5.5 to 3.5.6 but the problem remains. Any comments?

The latest news from this issue can be followed from the related Mozilla Support Forum.

The problem re-emerged when I downgraded Firefox from v4 to v3.6.16. Then the new version (3.6.17) was released, I upgraded to that version, and the problem was solved.

Do you have just one tab opening on Firefox? – admintech Dec 21 '09 at 15:19
Yes, a blank tab opens when I open Firefox. – Mehper C. Palavuzlar Dec 21 '09 at 15:21
I've only had this happen when updating a component that tries to open a "what's new" page on restart, or sometimes Xmarks (Foxmarks) being too eager. Seems like you're not alone though, so I'd keep an eye on this thread:… – MetalMikester Dec 21 '09 at 15:59
I've had this happen when multiple tabs are opened on startup, and several of them require a password. Ganesh's answer seems to be a fix for that one. – ℝaphink Jan 6 '10 at 11:52
The problem seems to vanish on Firefox 3.6. – Mehper C. Palavuzlar Jan 26 '10 at 9:44

A possible workaround is to use: Startup Master - A Firefox Addon.

The issue may be that some addon is trying to access a site for which you have saved your login credentials in the password manager. Hence when it tries to access the site, it prompts for a password. (may be 2 addons doing that the same time)

Its not related to Weave as I also have the same problem but I do not use weave. – phaedrus Jan 4 '10 at 18:39
As per what I know, everytime firefox encounters a website for which it has credentials stored, it will popup a master password box. You can simulate it by starting firefox & open Orkut & Facebook in two separate tabs. – Ganesh R. Jan 5 '10 at 4:46
Startup Master was a good workaround. I've set this as the accepted answer. However, the problem was gone after updating Firefox to version 3.6+. – Mehper C. Palavuzlar Mar 28 '11 at 10:46
