Unable to download add-ons with FF version 59.0.2 (32bit) I do not know when it happened but suddenly I could not download any add-ons from https://addons.mozilla.org/en-US/firefox/ http://prntscr.com/j9jh1e FF has been re-installed but still No! I used Norton Security with FF for a long time. The extension is just like this: http://prntscr.com/j9jj8q when i go to https://addons.mozilla.org/en-US/firefox/themes/ I can only see this: http://prntscr.com/j9jk58 Photos can not appear. After installation, the image can not be displayed. I can only download and install the noscript from https://noscript.net/getit http://prntscr.com/j9joh7 Also, it is not possible for any add-ons. How do I do? I also use chrome and it's still normal.

There are several possibilities for this.

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

  • Clear the Cache and
  • Remove Cookies

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Thank you for the coded certificate. Weirdly, it says:

This could be a side effect of "Norton Safe Web" but unless your Norton software is very out-of-date, you should at least be getting a valid certificate when it intercepts your connection.

I must remove Norton ConnectSafe settings?

This is my norton security. I keep updating normally. http://prntscr.com/jaftub Just recently I could not connect the FF add-on because Norton ConnectSafe has blocked mozilla? :<

Could you put in a request to Norton to explain what is going on? I don't think all Norton users are blocked from installing add-ons for Firefox.

more options

The Norton page you showed us says; Setup Required. That is up to you.

To its left, press Security. Then LiveUpdate. Any problems?

more options

Yeah, thanks for everything that was resolved. My only problem is Norton ConnectSafe.
