Firefox username editing

My Firefox browser is unwell. When logging into websites that I have used before, Firefox shows the username. A few days ago I forgot to move to the password field and keyed the password into the username field. This should not be a problem - highlight or right click on the text that is to be deleted, press delete, and it's gone.

For reasons that are unclear this is no longer possible. I do not know if it's due to a FF upgrade, a Win 7 upgrade, or a bug. I cannot find advice on the Mozilla website about how to fix this; all information I found is dated and refers to old versions.

So it may come down to delving deeper into Win 7 to edit or perhaps delete the file that remembers all the usernames. Advice to resolve this issue would be valued. Thanks.

Hi Tharwatime, To find Firefox Profiles first go to


Local Disk C

Users

User Name

App Data/Roaming/Mozilla/Firefox/Profiles


In case it is a hidden file, from the start menu, click control panel, type in folder options, view, and

check show hidden,files,folders and drives. Hope this is of some help.

Ethel, thanks. All I can see in ~ Firefox/Profiles is one folder, ff.default. I've selected show hidden, and nothing else comes up, not even in Total commander. Asking via dir *.* /A:H has nothing either. I'm unsure what to do now. Firefox has been quite good until now. I have should old versions going back years on full backups.

Hi Again, You may have already looked, but Firefox is also under

App Data/Local/Mozilla/Firefox/Profiles


Local Disk C

Program Files x 86/Mozilla

Hi again, One more place I just remembered.

In the start menu search box

Type in firefox.exe -P

A box will come up with Profiles, maybe something is there that may help.

This is ~Mozilla\Firefox\profiles.ini

[General]
StartWithLastProfile=1

[Profile0]
Name=default
IsRelative=1
Path=Profiles/ff.default

It was last altered in June 2016. I cannot see what to do here. The folder ~ff.default has about 20 folders and 50 files, some recent. I cannot identify any as being germane to editing the FF settings.

Hi again, Have you tried under the Firefox menu, click options and up the top you see about preferences,

change this to about profiles, and see what is listed there.

Competing priorites of late.

I found ~ff.default\logins.json, which says
{"nextId":1,"logins":[],"disabledHosts":["http://www.non-ffwebsitename.com.au"],"version":1}
I cannot see how this relates to a Firefox login

Advice above says to go "Firefox menu, click options and up the top you see about preferences". This brings up a screen called General, with a list at the left General, Search, Content and five others. There is no "about preferences".

I cannot see from the screen shot where Saved logins is located, and it does not come up on a search from the start button or the command line.

It's hard to know what to do next.
