Refreshed foxfire; now plugins and security (password requests) are screwed up.

Question

Recently picked up a virus. Did the things you would expect including malware and add-on elimination. The ad ware problem is fixed. I "refreshed" foxfire in the process of the above. Now I am prevented from installing any add-on. Foxfire prevents it and when I say allow, it tells me there is a communication problem. Also, I use LastPass as my password program and I can't get back to working as it should (auto login and passwords).
Also, foxfire gives a screen saying "password required" and then "please enter the master password for the software security device". I never set FFire with a password and can't understand why all these security roadblocks are now present.
I hope this helps you. I need some advice to solve this.

Answer 1

Try to set up a new profile to see if the problem is still there.
'''https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles'''
'''Windows: 32-bit''' C:\Program Files\Mozilla Firefox\firefox.exe -p
'''64-bit''' C:\Program Files (x86)\Mozilla Firefox\firefox.exe -p
'''Mac:''' Navigate to '''/Applications/Utilities.''' Open the Terminal application.
In the Terminal application, enter the following:
/Applications/Firefox.app/Contents/MacOS/firefox-bin -p
'''Linux:''' In '''Terminal''' run: firefox –P
For users who have one or more builds from mozilla.org this will not work.
It would be best to have the full path so if you had placed the untared contents
in a folder in /home it would be /home/<username>/foldername/firefox/firefox –P
An easy way would be not to do it in a terminal but in say a launcher since
you have to point it to the firefox script in Firefox folder you can then add –P
on end. You can also have the exact "profilename" after the -P so Firefox
will start with that Profile.
