No add-ons coming from https://addons.mozilla.org/en-US/firefox/ can be installed in my Mac, all because of a single issue ("Download failed. Please check your connection."). I've noticed that images in this site cannot load properly as well. I checked the console and it seems that the GET request was responded with 404. Install requests sent to other websites seem to be working. I successfully installed zotero from its website and some other add-ons via downloaded .xpi files. However, some .xpi's cannot be installed directly either. I got a message saying this add-on appears to be corrupt.

I duckduckwent this issue and tried all the following solutions (though none has helped): 1. Added "xpinstall.enabled => true" and "xpinstall.signatures.required => false" in about:config; 2. Downloaded the .xpi file directly using other browsers, but when I tried to add it manually, I got the message saying this add-on is corrupt. 3. I tried InstallTrigger.install({URL: "https://addons.mozilla.org/firefox/downloads/file/1168281/adblock_plus-3.4.2-an+fx.xpi?src=search"}) in the console and still got the connection error. I clicked on several install links in add-ons websites and they came back with 404. I think these links were redirecting me to addons.mozilla.org.

I don't have any antivirus software in my Mac, at least not that I know of. I enabled "allow site to install add-ons" and "allow pop-ups", etc.

I just updated to Firefox version 64 and noticed that you can no longer turn off update checks.

The only available options are "Automatically install updates" and "Check for updates but let you choose to install them".

I administer a public access computer lab and don't want "A new version is available!" popups to appear while our patrons are using our computers.

Is there a way to turn off update checking in this version of Firefox? Perhaps in about:config?

When I started Firefox this morning, I got the error message in the subject line this morning. The only button is "OK", which banishes the error message. The browser doesn't show up.

This evening, I checked for Windows updates, and the only ones pending were security definition updates and Silverlight (which I don't knowingly use).

A google search of the following doesn't yield anything helpful:

XULRunner error "Platform version '64.0' is not compatible with" "minVersion >= 63.0.3" "maxVersion <= 63.0.3"

If anyone can suggest anything, thanks....I am running Windows 7

I use industry specific program called resnexus for managing my bed and breakfast. Every time I search for a guest in the resnexus tab, it adds them to my saved addresses under "Forms and Autofill". I have already created 2 form fills and don't want Firefox to automatically add new items. I want to keep autofill turned on as I do lots of online petitions. Any suggestions?

That's fantastic, especially as Microsoft are moving to Chromium, you're really selling your service.

locking this thread as support is being rendered in the original thread - https://support.mozilla.org/en-US/questions/1249850


I've already asked the question and gave my email address but now didn't see how to get to the forum. I started out having a problem hearing sound on facebook and youtube videos. Checked sound on pc - fine. Had a pc expert uninstall and reinstall firefox and the sound worked last night. This morning the sound on those videos is gone so I uninstalled and installed firefox again and now it says that facebook and youtube don't have safe connections!!!!! I didn't appreciate being offered the reimage app and then finding out it would cost me something after it went through my pc. I am being as nice as my frustration allows.


Your connection is not secure

The owner of www.facebook.com 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.

Dear Community,

I recently switched back to FF from chrome and I really love it. There is one thing I cannot get to work though: I would like to have google as default search engine but without country redirect. In Chrome this is done by using https://www.google.com/search?q=%s&pws=0&gl=us&gws_rd=cr as search engine. What is the equivalent in FF?

Thanks in advance!

I am using the current version of Firefox and when using a particular website (Microsoft CRM Online) I get frequent popup dialogs . The issue I have is Firefox will ask me (in a dialog) if I want to "prevent this website from creating additional dialogs". I understand the reasoning behind this, but I don't want it. I would prefer that the dialogs behave in the same way they do in other browsers.

Can I disable this feature either at the browser

On a Mozilla How-To page (https://support.mozilla.org/en-US/kb/block-autoplay), instructions are given for going to Permissions under Privacy and Security to easily select to allow or not allow autoplay of videos.

But on FF 64, that feature simply doesn't exist! (See uploaded image compared to image on the above linked Mozilla help page.)

I'm seeing a couple somewhat recent discussions about stopping autoplay in Yahoo, but it's a bit above my head, as there are configurations talked about that I don't know how to start doing.

Also, it's unclear to me in those discussions if Mozilla intentionally got rid of this easy-to-do setting, and if so why, and if it plans to bring it back or what.

In the meantime, what exactly do I do to stop autoplay of videos?

The subject pretty well describes the issue. I have to *quickly* force close, restart Firefox and restore windows, with the multiple blank windows unchecked.

I have viewed probably thousands of RSS links without issue before this version.

I only see the issue with RSS links but not all of them Maybe this sort of html is causing the problem: <atom:link href="https://www.easternherald.com/feed/" rel="self" type="application/rss+xml" /> I can see no other redirect code, and this type of code seems to be a common factor.

All dodgy links work fine with MSIE under Windows.
