"Expect-CT is a new security header which is, at the moment, only supported by Chrome and Opera browsers. It allows a website to instruct the browser to reject any certificate not found in Certificate Transparency, a read-only public log of certificates which can be audited. Because Expect-CT is an HTTP header, it is a trust-on-first-use protocol that relies on long-term caching to ensure security. While Expect-CT does not prevent a compromised Certificate Authority from issuing a fake certificate, it does limit the damage by forcing the addition of the certificate to the log. The domain owner can then report the fake certificate and attempt to get it revoked." [Protonmail]

Ever since installing Firefox 70 I have been having problems with various programs seemingly changing on their own. I have a personal finance program which has dropped the last 3 months info and I have no idea how to recover it. It has also somehow changed the entire program to a different version, but has still kept the version I have of this program, so now I have 2 personal finance records which I need to watch. All I know is I only want the original version, but I'm not what will happen if I delete the version which I believe was installed when I upgraded to Firefox 70. I have also had problems with pages loading and freezing up. If this is all caused by upgrading I do not want Firefox 70! Also, I really don't like the new colors of the "fox". Can they be changed?

In the Gmail client, I often go to the drop down menu (3 vertical dots) and choose "Filter messages like these" to sort future emails into one of the many "labels" I use. I tried to do that earlier today, and the dialogue box that normally opens when I chose "Filter..." did not appear. I tried it with several emails - still no dialogue box. I then opened Google Chrome (see attached image), went to the same email in my Gmail client, and the feature worked. I suspect that the issue with using the feature in Firefox is that I upgraded to macOS 10.15 Catalina last night. I am using Firefox 70.0 for my browser as I prefer many of its features over what I have in Chrome or Safari. Please let me know if you are aware of this issue, or whether I am an outlier, having a one-off problem.

Firefox 70.0 x64. I have a number of add-ons installed, but have reviewed their options and don't seem to find an explanation.

As shown in the image, there is a down arrow character, more like an inverted caret, at the right end of my tabs bar. When I mouse over it, it says, "List all tabs." If I click on it, that's what it does: it lists the currently open tabs. But it seems to exist only after I've added a newly opened tab, as distinct from restoring previously opened tabs. In Customize, it is grayed out and refuses to be dragged away.

Any ideas where this might have come from, or how I could proceed to find out?

This solution https://support.mozilla.org/en-US/questions/1171243 still leaves a narrow strip under the navigation bar. Is there a way to get rid of it as well?

Previously, I would use this code snippet in userChrome.css: [#PopupAutoCompleteRichResult {display: none!important;}] Then, starting with version 68 it stopped working and I found out I had to change it to this: [#urlbar-results {display: none!important;}] And after Firefox updated to version 70 it quit working.

My computer becomes unresponsive at times while Firefox is running. I restart it. When it is back up, Firefox with all the open tabs prior to the computer is still running. Every other application has to be restarted. Why is this? How is it setup to do this?

I successfully downgraded from FF 70 to FF esr 68 in my soho. Alas, I the esr version doesn't resolve the address of my office server, whereas FF70 does it and so does chrome. When I try something like http://myserver.myhome.xx:myPort , FF esr responds with an error page "The requested URL could not be retrieved". I can use the local IP as a workaround but that is not what I am looking at. Is there a setting that makes FF esr resolve local addresses?

The "i" icon to the left of the address on the address bar that can be used to drag to the desktop to create a shortcut to the page has disappeared and has been replaced by an "Enhanced Tracking Protection" icon. How do I get the "I" icon back? (Deskcut, unfortunately, is no longer available as an add-on to create shortcuts).

In Full Screen mode, all the icons in Bookmarks bar is not responsive, as if being freezed.

"Show web developer tools" and "Downloads" Icons in Toolbar malfunction in the same way.

All the Icons boxed in red lines malfunction.

I have many folders to keep my mail organized. Some of the folders have diapeared. Help! I need them. I try to make a new folder, it says that folder already exists.... That's good where?

There is no Address option in my Firefox Sync as described in the documentation. Can you enable it or is the documentation for a future version of Firefox Sync?

I am a blogger and while doing some work in Firefox browser my browser automatically opens some unwanted pages. While doing some research in the profile setting, I found some codes in profile config. setting. I am keeping only one default browser " 43xkzuc9" but another one also there(c1z1xvoz). I suspect that may be the reason. Kindly somebody help me to resolve the issue. I am copy pasting the code found in the profile configuration setting below.

[Install308046B0AF4A39CB] Default=Profiles/43xkzuc9.default-release Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/c1z1xvoz.default Default=1

[Profile0] Name=default-release IsRelative=1 Path=Profiles/43xkzuc9.default-release

[General] StartWithLastProfile=1 Version=2

Thanks in advance,

The only thing that really differentiates private mode with normal browsing is the little purple circle in each end of the menu bar. I'd like the whole menu bar to get a different color - is this possible in any way?

All the extensions I've found that claim to do this don't play well with dark themed firefox. (Technically default theme on dark win10.) Also they don't work well with the latest versions of firefox.

YouTube HTML5 1080p@60fps videos in full screen are choppy, independently if the hardware acceleration is turned on or off. I've tried clean profile, I've tried these methods: https://old.reddit.com/r/firefox/comments/amy7j6/its_been_years_since_firefox_has_stutters_on/efpuhc5/ Nothing works. How can I fix this?

That is not a hardware issue - I have no problems with watching 1440p@60fps videos in chromium.

In this case newsletter links from "The HIll" is routed through some intermediary site, click1, and there is some https issue in the switch.

I take a lot of newsletter and I'm finding FF more and more unreliable in opening links associated with newsletter services like MailChimp, Click1, or Constant Contact.

Hi guys,

I am having some trouble on this topic, could someone help me?

Let me explain, when i left the tab of onedrive and reopen it's already sign in. Is this usual ? There's other form to sign out ever time that you leave the page?

Of course, besides WHAT WE ALREADY KNOW ABOUT CLEAN COOKIES , HISTORY , CACHE AND PASSWORDS.

Computer opens up on my Facebook homepage. Then, if I open another tab and try to open any other website, nothing happens - I'm on Facebook and that is where I stay. I should add that I have the same symptoms on Microsoft Edge (including as a private page), Firefox as a private page, and Avast Secure Browser.
