What do you mean, 'a short period of time' ? Firefox Password Manager should save all recorded passwords until you remove them.

Password Manager - Remember, delete, change and import saved passwords in Firefox

firefox is not saving a lot of website passwords. must be some safeguard restriction. But is there any way to force it to save all of them regardless going forward until yeh - I delete them??? tx!

Short of a refresh and a new Profile to see if it is the issue you can use a Password Manager like Norton (not shown) https://addons.mozilla.org/en-US/firefox/search/?platform=windows&q=password+manager

If wanting to fix Firefox for the error on passwords : SAFE MODE

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

In Firefox Safe mode these changes are effective:

• all extensions are disabled (about:addons)
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored (chrome folder)
• default toolbar layout is used (file: localstore-safe.rdf)
• Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
• hardware acceleration is disabled (Options > Advanced > General)
• plugins are not affected
• preferences are not affected

TEST''''is issue still there ? What adblockers are you using as that could be the issue is your not getting the cookie to be able to set the password.

please try a Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st: Delete your Cookies and Cache and TEST.

Would you please take a look at these articles :

The Password Manager, as mentioned by FredMcD, should be able to do what you want, even if you only want to do this for a short period of time - in which case you can uncheck 'Remember logins and passwords for websites' (Options => Privacy & Security).
