How To Remove Saved Usernames and Passwords from Firefox

Have you ever wanted to remove a wrong username you typed in a webmail login screen with your Mozilla/Firefox browser or just what to remove it from your friends browser you just used ?

Unfortunately, only usernames that actually have a saved password show in the "saved password" option menu.

So this is a quick "how to" delete a username from a login screen when using Firefox:

1. Go to the website that has the username that you wish to delete.

2. Type de first letter of the username

3. When you see it pop up in the dropdown menu under the username field (as seen in the first image on this page), simply make sure the username that you wish is highlighted by rolling over with your mouse

4. With the name selected highlighted let the mouse rest and hit the SHIFT+DELETE

it's that simple.

Cheers!

Firefox bookmark JSON file extension

The JSON file extension is used by Mozilla Firefox web browser. Used by Mozilla Firefox from version 3.0 for bookmark backup in JSON format. Firefox version 1.0 - 2.0 stored bookmark backup in HTML file.

JSON is a part of the ECMAScript standard since ECMA has defined in 1999 the eval function that parses the format. It has been popularized with the success of Ajax. The JSON word appears often when one is speaking about Ajax. We know this is another data format, that can replace XML, and this format is supported by a lot of programmers.

You do not need to open the *.json file, you can use Firefox to import the backup file. You can import them using the Library.

Open the Library - Bookmarks → Organize Bookmarks

To import the bookmarks from the json backup, in the Library choose:

Import and Backup → Restore → Choose File

Note that importing a *.json file will replace any existing bookmarks with those in the *.json file.

Firefox automatically creates 5 backup files, and these backups are stored in the bookmarkbackups folder inside the profile folder. On Windows Vista the usual location for the profile folder is:

C:\Users\"Windows login/user name"\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default\

xxxxxxxx is a string of random characters, the second half of that part of the folder name is normally .default but may be something else. The Application Data folder is usually a hidden folder. To show hidden folders, open Windows Explorer and choose:

Organize → Folder and Search Options → Folder Options → View and select Show hidden files and folders

MIME: application/json

Firefox: View Source Code using External Editor

Would you like to view the source of a page on your favorite editor ?

To do this, there are two entries to modify at the "about:config" page of Firefox.

Search (filter by) for "view_source.editor" then change the following keys:

view_source.editor.external: Change this to true (just click over it two times).

view_source.editor.path: Change this to the explicit path to your editor of choice.

Example: I have Notepadd++ installed so, in this case I used "C:\Program Files\Notepad++\notepad++.exe" without the quote marks.

Have fun!

Remove Microsoft .Net Framework Assistant From Firefox

Remove Microsoft .Net Framework Assistant From Firefox

Have you noticed one of these problems:

1. popup saying that NET Framework cause stability problems
2. strange firefox crashes
3. yahoo mail (the classic version) doesn't respond correctly when you choose things and send messages (that "loading" message an slow response or nothing)
4. some times just can't load new URLs.

Take a look at the installed add-ons in Firefox search for an add-on called Microsoft .net Framework Assistant.

That add-on is different from most other installed add-ons. The first thing that you will notice is that you cannot uninstall it as the uninstall option is inactive in Firefox, specially for versions "0.0.0" or "1.0.0".

First try to disable it if it's active. Start Firefox again and check.

You might also realize that you did not install that add-on actively which means it must have been installed by another application.

If you use Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 , you can go to this page: https://addons.mozilla.org/en-US/firefox/addon/9449

and upgrade the .Net Framework Assistant, and then you can uninstall the extensions or just keep it "disabled".

If you uninstall and after restart it still is there try this: http://support.microsoft.com/kb/963707

The pop up from Microsoft's framework error message or the "Just in Time Debugging" from Microsoft is annoying but a very easy fix.

Go to the control panel under the Start Button. Click on Internet Options Turn off the Microsoft Debuggers and your Firefox will never have any more issues.


Have fun!

Firefox lento com dificuldade para abrir urls

Eu pessoalmente gosto muito mais do Firefox do que do IE.  Uso no ambiente Linux e também no ambiente Windows.

Se você notou que ele está ficando lento ou com dificuldade para abrir algumas páginas que estavam abrindo normal antes das atualizações, a causa pode ser o plugin-container.exe que foi criado para dar mais proteção ao ambiente do Firefox que está cada vez mais "cheio" de plugins (programinhas que adicionam funcionalidades extras), mas que pode derrubar seu desempenho se seu micro tem poucos recursos (eu uso um Pentium III de 1GHz com 1,5GBytes de memória até hoje).

Como então podemos desabilitar este "protetor" de plugins, bem você terá de mudar algumas preferências na configuração do Firefox usando o "about:config".

Atenção: antes de continuar a ler, informo que ao modificar os parâmetros do Firefox, você pode travar o browser e se der tudo errado terá de reinstalar.  Avisado!

Abra seu Firefox e digite o endereço de url: "about:config" (sem as aspas).  Vai aparecer um aviso e se tiver coragem de continuar escolha "sim" ou "continuar" ou qualquer outa coisa do tipo.

Digite na linha do "filtro" o seguinte: "dom.ipc" (sem as aspas)

Basta clicar nas linhas indicadas abaixo (na imagem em negrito) para ficar igual e pronto!

Resolvido, agora o desempenho deve melhorar muito.  Mas em contrapartida ficou sem a proteção de "plugins" que podem travar seu browser.
