My Adguard add on was disabled by Firefox about midnight May 3, 2019. Now when I try to install Adguard or any other add on I get the message, "Download failed. Please check your connection." The message occurs whether or not I am signed in to my Firefox account. My security package is Norton Online provided and updated through my ISP Earthlink. Thanks, in advance, for your attention to my problem.

Suddenly while browsing, I got a bar notification saying that some of my addons had been disabled because they were unsupported. Clicking the button took me to a page that showed no addons, but linked to a page for Legacy Addons in which I found 25 of my addons (That's literally all but 2) have been marked as "not verified for use in Firefox" and disabled, despite literally all of them working mere seconds again and a large majority of them being obtained directly from Mozilla's official addon website! Firefox didn't even receive an update or anything, they just all randomly got flagged out of nowhere for no reason. Why are all of my addons suddenly marked as unverified and disabled, and how can I enable them all again?

(The uploaded image doesn't seem to be showing in the support thread, so here's a direct link https://puu.sh/Dnxlm/b471b782d7.PNG )

I have just downloaded Firefox for the first time, as Internet Explorer support has ended and some web sites activly make their pages not work properly, plus I hate Edge. All is good so far, except I am constantly closing a Firefox Privacy Notice tab. This appears to pop up when I select my home page (set to google.co.uk).

Just today Mozilla suddenly reported that several of my extensions where outdated and had been disabled. When I checked the 'legacy extension list' is showed every single extension as being unsigned, the list includes:

Add Block Plus IDM Integration module Malwarebytes browser extension

I have gone to the add on page and tried to install (or re-install) the latest version of each of these and it fails with the error "Download failed. Please check your connection." As I know my network connection is good, this is clearly bogus. So far all I have done otherwise is run a full virus scan with malwarebytes (and got nothing) and reboot just in case. Some searches on the web have turned up installation failures like i am getting, but most of them where a year ago or more and specific to a given add on. I haven't found anything on mass disabling all extensions.

Currently running version 66.0.3 (64 bit) of mozilla.

Thanks for any help you can provide, Eric Hough

All of my add-ons were suddenly blocked and disabled while watching a video on Amazon's Prime Video service. When I go to the Add-Ons manager they are all listed under the Unsupported section. Clicking the More Information link for each takes me to https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox

Now, I can't vouch for each of the Add-Ons I've listed below, but I know that the HTTPS Everywhere add-on (2019.5.2.1) has a valid signature and has been working for months for me on the up to date version. All of the add-ons I have are still up on addons.mozilla.org, I just can't use them. Any attempt to download them from addons.mozilla.org results in a "Download failed. Please check your connection." error message:

The address bar is a simple concept. You type an address in, you hit <Return>, and the browser takes you there.

Not in Firefox 66.0.3!

In 66.0.3 you type in an address (meanwhile the bar is giving you random crap to "help" you and there's no way to turn this off), you hit return, and....nothing!

The only way to actually go where you want to go is to type the address, *click or tab OUT of the bar*, and then *re-enter the bar*. Then and ONLY then will <Return> actually do something.

Based on other questions, this has happened before too.

Why can't you just have an address bar that works as an address bar?

Just minutes ago I got a message that One of more of my add-ins cannot be verified and have been disabled. That turned out to be all of them! On the add-in screen they also only show up under legacy add-ins, even though I've been using each of these WebExtensions for over a year now. Add=ins include PasswordMaker X, uBlock Origin, YouTube Video and Audio Downloader, Reddit Enhancement Suite, ViolentMonkey, all of my skins, and much more. Some of them I just got from the add-on store last week! What's the deal here?

1) Avast Online Security could not be verified for use in Firefox and has been disabled 2) Avast Safeprice could not be verified for use in Firefox and has been disabled 3) DuckduckGo Privacy Essentials could not be verified for use in Firefox and has been disabled

These three items are not working now, and they are important to me.

Kindly contact Avast and DuckduckGo, and figure out a COMPROMISE to make these items still work on the latest Firefox version 66.0.3. If you can't do that, then I can no longer use Firefox.

My safety is more important than whatever weird idea your update guy had, and who apparently used the "ZERO nada zilch microsoft method of testing" before unleashing it on the unsuspecting user. When will you guys learn about TESTING!?

Firefox Is Changing The Default Paper Size For All Printers When One Is Selected

Hello!

A little background info on what we're dealing with here. I work in a store and we own two workstations. Each workstation shares our two printers. One is a Star Receipt printer, the other is a Brother full size paper printer. Now Workstation2 is working without issue. We are able to print with the system specific default printer settings and nothing changes between printer. All good to go.

Now the issues stems from Workstation1. Our Star Receipt printer is set to print '77MMXRECEIPT', however when we select the Brother printer from the drop down menu then switch back to the Star Receipt the default paper size is forced to 'Letter' which causes the Receipt to print like a large sheet of paper which means we only get a portion of what we are printing.

This wouldn't normally be a problem, but due to some undefined steps(I'm not the only user and we don't always print from one website) the Brother printer is changed to default in Firefox which means that when we select the Receipt printer for printing, the default is again set to 'Letter' until we go to File>Print and set it to default again with '77MMXRECEIPT'.

Here's what I've done to test where the issue is this. I've changed and confirmed that when the Receipt printer is forced to 'Letter', the windows printer settings for both printers does stay on the default settings. I've also confirmed that the printer settings work on all browsers but Firefox and within Firefox I have gone into the .js settings file and deleted anything mentioned as 'print_' as well as going to Help>Troubleshoot>Refresh and completely setting all settings to default with nothing changing. I've also gone into About:config and tried resetting the default printer to no avail. The setting is always forcefully changed to 'Letter' when first switched to Brother printer and back to Star Receipt printer.

My take on it is there is some saved cache or settings file that has recorded and saved the Brother settings along with the Star Receipt settings and sets them both when switched to Brother. I've attempted to check both workstations and compare settings, everything appears the same. I have no idea where else to go on this as I don't know Firefox that intimately. Short of reinstalling Firefox I've done all I can think of.

My current version of Firefox is 66.0.3 (64-bit) labelled as Firefox Quantum.

Please let me know if there is anything you can think of! Thank you for your help.

I have looked in the browser for profiles, and it shows only the one currently in use, no old profiles show.

Any help would be appreciated!

On the extensions page, all of the adblocker extensions show up after a search, however when I attempt to install any of them I get a message that says "Download failed. Check your connection". This occurs on all ad block extensions that I have tried. I tried AdBlock Plus, UBlock, and Privacy Badger.

I also tried some other extensions on the main extensions page. None of them work. Is your extensions server down for maintenance or something?

I am obviously connected. I have attached a screenshot of the issue.
