There are two things for you to check.

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

• Make sure your Internet security software is up-to-date (i.e. you are running the latest version)

• Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

Many site issues can be caused by corrupt cookies or cache.

• Clear the Cache

Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

and

• Remove Cookies

Poke around safe web sites. Are there any problems?

Then restart.

@FredMcD, Did you read my post? I said I didn't updated Firefox before it happened. One version. It just worked and now it just doesn't works.

Today it works again. WTF? Did restart solved the problem? Do you think it's because of cache?

@FredMcD thanks for answer but it's too late. Problem fixed by itself, as it began.

Thread isn't closed. IDK why it happened.

P.S. this browser is pretty shitty but others even worse.

I would just observe that you are using Aurora 34.0A1. My understanding is that it is updated almost every day.

If you have further problems I suggest you retreat to Fx 32.

@alan_r did you read text? I saying third time: I DID NOT UPDATE IT FEW DAYS. What's wrong with you, people?

You are on a development channel which updates regularly and automatically.

Such channels are usually used by experts for testing purposes(they would often have a stable version as well). If you don't update it there is absolutely no reason to be a couple of versions ahead of the stable release. Your opinion of the Firefox browser is based on misuse. You will find a stable version much better for general use.

Users like yourself who are trying to help would appreciate a little more respect.

@alan_r >> and automatically.

I TURNED IT OFF. I UPDATING MANUALLY. Please, stop posting here. You're useless.
