Firefox Forum di supporto

I have been having this issue for months now. Every time I search for something which contains terms like "rogue", "malware", "virus" firefox closes without any notice. This first happened when I searched these terms on youtube and google.

Is some sort of malware trying to prevent me from searching the term "malware"? Also, there is a similar question here which also states that firefox closes when the term "rogue" is searched for but I can't view that question because every time I try to open the question my firefox crashes because it contains the term "rogue" ...

How do I fix this issue? Please help me out, thanks.

Chugging along just fine as usual, in the early part of today(using Firefox several times). With Firefox closed, I went to open it and it took ages to open fully. When it did open, the familiar toolbars were there, including my Bookmarks toolbar. The Bookmarks toolbar is showing the icons of sites that I have put there, and it is showing my self-created folders on it (containing various website shortcuts etc). The only difference is that the folders are grey instead of yellow. However, nothing is actually HAPPENING. No matter what I click on, I am not reaching any website whatsoever. I cannot actually go anywhere at all with Firefox. My internet connection is working just fine. I can open email software and I can open (and use) Internet Explorer. Why has my Firefox just stopped functioning on my Windows 7 PC? It is Firefox Quantum ESR 60.2.0esr. I am typing this support request on my Windows 10 laptop where Firefox Quantum 62.0 is working ok!

Wanted to update to newest version but was told it is not possible. Downloading of new version is blocked with message shown in attached screenshot. How to proceed?

After updating to Firefox Quantum 62.0, when I launch the browser I get an insecure connection warning....on the mozilla Firefox start page!

Your connection is not secure

The owner of start.mozilla.org has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

Is Firefox trying to prevent me accessing it's own web page???

Help!

... and every other site I visit (cnn.com, google.com, etc.) How do I fix this, or is an issue with 62.0? I had to use Chrome to even access mozilla.org. I can't get to any website.

After a last update of Firefox, Kasperksy told me, that firefox websites are not protected by this security software and they force me to use google chrome for to be protected. But I want to use firefox because of its tracking protection and privacy sites. Is there any reason to bar Mozilla from protecting. In former times there was an add-on, which doesn't exist any longer.

I have several months with this problem, sometimes when I open a new tab from a link is stay with icon of loading but nothing happen. If I open several times finally it loads, but is very frustrating.

I have last version of Firefox, I tried a clean install still happen.

Please let me know how to fix it.

I've just done a Firefox Refresh which has been a bit of a disaster as any attempt to connect to any sites now gives a message to say that they don't have the right certificate and are insecure. The same goes for your own site!

Any help please??

Hi,

Yahoo Secure Search disappeared from my Firefox browser after a Firefox update. Do you know how I can get it back?

McAfee Web Advisor (which I believe secure search came with) is enabled and I have added Yahoo Search to the search box but I can’t see how to get Yahoo Secure Search back. I found this very useful because it would flag up dangerous sites in a search list thereby preventing me clicking on them.

Advice appreciated.

Thanks.

I use Windows 10 Version 1803(OS Build 17134.228). I use Firefox Quantum 62.0(64-bit). After the most recent update to Firefox, Firefox can no longer open 75% of the websites I routinely surf. All of the offending websites supposedly have certificates with invalid signatures. Oddly enough, those same websites are no problem to Internet Explorer, Google Chrome, Opera or Microsoft Edge. What are you guys trying to do, Shoot Yourselves in the Foot Again? Get this crap fixed.
