Last night I was installing a software and it tried to install SEVERAL viruses on my pc that I successfully managed to stop the installation. But I got another serious threat that I want to know whether it's still there and how can I get rid of it.

When I opened the software I was trying to install, it automatically opened a new tab on my Firefox opened window and in that same instant I knew something wrong was happening. The thing is that it loaded some pages in the same tab, using a full redirection so I couldn't go back to them and it ended in a modified Google (www.google.com/"something"). The thing is that I tried to go to the download page and Firefox started telling me THAT IT DIDN'T EXIST, then I knew something heavy was going on. I used the Reset tool (about:support) and parts of the virus got lost in the process. But the thing is that even when Firefox is set to start at https://www.google.com.uy or even when I put the blank page option for starting, it ALWAYS redirects me to the page of the virus ( http://www.istartsurf.com/?type=sc&ts=1412823435&from=sky&uid=WDCXWD5000AAKX-00ERMA0_WD-WCC2EHK4239242392 ) and if I then open another tab/window without closing the main, it justs do as I configured it (home: google, new page: blank).

Since I already reset Firefox, I want to know whether I should use another mechanism (likely deleting the entire ...\AppData\Roaming\Mozilla folder) or just reinstalling Firefox? I have already passes a full scan of my PC with AVG Internet Security 2015 (found 23 virus on the virus main folder and some Windows folders) and passed Ccleaner against every Firefox component.

If I forget about adding anything, please let me know.

Since the last update, according to Avast, Firefox tries to open the malicious url https://p2.dntrax.com on startup. Is this a false positive, or is there something wrong that I need to fix?

(The startup page is my home page, a simple non-scripted plain html file that resides on the hard drive. This has not changed in years.)

Firefox 19 seems to have dropped the warnings about insecure HTTP(S) contents, i.e. warn about submitting form data over HTTP (no S!), mixed secure and insecure contents, leaving a HTTPS page and so on. How can I get these warnings back? Or are there now different warning mechanisms (e.g. showing an insecure form submission in adance, that means at the time of filling it in)?

Since several months I have successfully used "lockPref" to lock settings (specifically, proxy settings) on Firefox 17 and Firefox 18.
I am running Ubuntu 10.04, and I have used the file:
/etc/firefox/pref/firefox.js.
Firefox 17 did not always honor those settings. Often it did, sometimes it did'nt. I also found that there is another file location some people are using (?), and this is:

usr/lib/firefox/defaults/preferences/vendor-firefox.js 

To be sure, I put my settings into both of them. With Firefox 18, it did honor those settings. So this was working well.
(Note - I have NOT used any byteshifting or anything, as one can read was necessary for old versions of Firefox. There being no clear documentation by version, I feel I have no way to tell if this is actually still required or not. It was working without any byteshifting on Firefox 17 and 18.)

I just upgraded to Firefox 19 - and voila (of course, I might say) again the settings are not being honored. This time they are NEVER honored. They are JUST IGNORED, EVERY TIME.

This is very upsetting - can someone please point out what is now changed?
Do I now need to use yet another configuration locking file location?
Or do I suddenly need to do this byteshifting thing - if so what is the procedure right now for this?

Settings I am trying to lock are:

//set proxy server settings
lockPref("network.proxy.http", "a.b.c.d");
lockPref("network.proxy.http_port", yy);
lockPref("network.proxy.https", "a.b.c.d");
lockPref("network.proxy.https_port", yy);
lockPref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");
lockPref("network.proxy.type", 1);

We are now using Chrome as much as Firefox, but we need to copy the Password logins from FF to Chrome.

Chrome wants a HTML file. Firefox exports as XML or CSV.

So how do we export to use on Chrome? Is there some clever little app that can do it and SEE Firefox from Chrome to export?

We use Firefox a lot for developing, but need Chrome for other purposes.

When I turned OFF RC4 and 3DES Firefox can't connect to some SSL-server. But Internet Explorer and Opera with the same (absence of RC4 and 3DES and to the same server) can do it.

Why? I think this is the BAD implementation of SSL/TLS or a BUG!

And why in Firefox there are no cipher suits with SHA-256? I see in ServerHello a cipher suite(choosen by server): TLS_RSA_WITH_AES_256_CBC_SHA256 (0x003d) But this cipher suite absent in Firefox!


Firefox cipher suits:

TLS_EMPTY_RENEGOTIATION_INFO_SCSV (0x00ff) TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a) TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014) TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA (0x0088) TLS_DHE_DSS_WITH_CAMELLIA_256_CBC_SHA (0x0087) TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x0039) TLS_DHE_DSS_WITH_AES_256_CBC_SHA (0x0038) TLS_ECDH_RSA_WITH_AES_256_CBC_SHA (0xc00f) TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA (0xc005) TLS_RSA_WITH_CAMELLIA_256_CBC_SHA (0x0084) TLS_RSA_WITH_AES_256_CBC_SHA (0x0035) TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009) TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013) TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA (0x0045) TLS_DHE_DSS_WITH_CAMELLIA_128_CBC_SHA (0x0044) TLS_DHE_RSA_WITH_AES_128_CBC_SHA (0x0033) TLS_DHE_DSS_WITH_AES_128_CBC_SHA (0x0032) TLS_ECDH_RSA_WITH_AES_128_CBC_SHA (0xc00e) TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA (0xc004) TLS_RSA_WITH_CAMELLIA_128_CBC_SHA (0x0041) TLS_RSA_WITH_AES_128_CBC_SHA (0x002f)

Firefox Passwords Not Being Saved

Running Firefox 45.0.1 on Windows 10 Anti-virus: Avira Anti-Virus Free Firewall: same

As stated, Firefox is not saving my passwords (or form information or maintaining Sync connection). I HAVE already read through the FAQs and other community questions and answers. I do have a Master Security password. I do know the password. But passwords are not being saved. I cannot find any other software that would interfere with this. I cannot find any setting in my anti-virus/firewall software (Avira) that has anything to do with this Firefox function. I am NOT using any other password saving software or extension or other application. There is no issue with the password manager exceptions file.

I do NOT have a problem with password saving on my Win XP PC. I DO HAVE SYNC SETUP AND TURNED ON but this does not populate the password manager on the Win 10 PC. It does sync everything else (although not all extensions seem to be configured to share all setup data and usage information, particularly tab group extensions).

Also, on the Win 10 machine, it periodically loses the Sync connection. This is very annoying. How do I prevent this? It never happens on the Win XP computer.

Also, on the Win 10 machine, it does not seem to populate form data boxes (name, address, email address, etc.) when I visit websites. Why? Is this also a Firefox issue or is this an issue with the individual websites? It doesn't seem to happen very often on the Win XP computer.

Please help.

Locking duplicate thread.
Please continue here: [/questions/967949]

Every time I log onto Firefox I get the following message:

"Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features."

I would like to fix whatever is causing this error message to appear, but I haven't found my, "application's profile directory" so that I can check for "read/write restrictions". My hard drive is 640GB with 554GB free space remaining.

I am running Windows 7 - 64 and am using Avast Internet Security 2013.

I was going to follow the manual troubleshooting as recommended, but I can't get online using Firefox. It starts to open but then stops with a "New Tab" that looks like it is trying to load (arrow going around in circle) but never gets past that point. I am using Google to connect with you for this help session.

What on earth are you thinking? We spent ages searching for malware & viruses because every time we open a new tab/window another tab opens with adverts! And we discover this is an actual firefox addition. (and "its clearly labelled as an ad" is a total lie!!!!!!!!!!!!!)

well $%^*(# you very much. Of course we are angry - what did you think would happen!

Thankfully we found a solution: about:config -> browser.newtab.url -> set it to about:blank

BUT WE SHOULDNT HAVE TO

v30 of firefox is a disgrace. My question? Why are you making us return to Internet Explorer?

I came across this and thought to pass it on; Java vulnerability: What you need to know Norton has been monitoring a vulnerability in Java that allows cybercriminals to lure Internet users to virus-infected websites. This vulnerability puts users at risk for malware attacks. Here’s what you need to know:

   All versions of Java SE 7 Update 17 and earlier are affected.
   Norton recommends all Java users download and install the software update released by Oracle as soon as possible.
   Users may want to disable Java if it is not required.
