1. In the upper left hand corner of the browser you should have an orange "Firefox" button. You won't see this if you have a navigation menu bar there. By default, FF now comes with this button, but if you have an older version, you will probably have the navigation menu (this is the File, Edit, View, History, Bookmarks, Tools, Help menu.
Right-click
after the "Help" option. In other words, any of the open, unused part of the blue strip to the right of the menu. If you click above or below this you will get a different menu from right-clicking. As shown...
2. On the drop-down menu you get. turn off the menu bar (top selection) when you do this, you will get the following...
3. Note that the menu is now replaced by the orange button. You can always change back by bringing up the pop-up menu you got by right-clicking and then just turn the menu back on.
Click on the orange button to bring up the following dialog box...
4. When you hover your mouse over the "Options" selection, you will get a drop-down menu to the right. The left margin of this box shows in the image but not the rest of it.
Instead of using this drop-down, click on "Options" to bring up a dialog box as shown below.
5. Click on "Saved Passwords..." You will get this...
From here, I can't help you any further. I don't have any saved passwords, but it is probably self-explanatory from here. Simply select "Show Passwords" at the bottom right just over the "Close" button.
From here you will be able to find your password if it is captured by the browser.
What if none of these methods work?
This final option should do the trick ... if you specified an email address when you installed the WordPress installation...
I do like telling Chrome to save my passwords, so if I have to I can use its retrieval list in the chrome menu . I realize there's a security problem inherent in doing this. (If I can access this menu, so can anyone who gets access to my computer. Far too easy.) So I am careful about what sites I let Chrome save passwords for.
Second, I do the send-myself-an-email trick for each user/password combo. I collect them in an oh-so-cleverly-named file. And I think I am so very clever when I just say in the email, follow algorithm. i hope my attempts at being sufficiently paranoid are never tested.
Thirdly, the algorithm itself. I never write it down anywhere, It's my own and I better never forget what it is. It does let me generate a password that is unique to each site. And i guess I could recreate it by looking at some of the passwords I have asked Chrome to save.
Fourth, when a site gives me an impossible-to-remember password, I go in and change it to my algorithm.
Last but not least, banking sites are an exception to all above rules.
And oh dear, just writing this makes me feel paranoid !
