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.

The main "Firefox" menu is in Japanese, but all the rest of the menus (File, Edit, View, History, etc.) are in English.

How can I change the "Firefox" menu's language back to English? I've already tried it in settings.

I am unable to attach screenshots for an unknown reason so will instead link them here:

It's really annoying trying to close a tab only to open a new one again because you middle clicked on the empty portion of the tab bar.

I got home, turned on the PC, loaded up Firefox, and ALL my addons are disabled and tossed into their 'legacy' pool of crap. No happy colorful theme, NO adblocker, no Ghostery... it even disabled my Bitdefender add-ons. Something is NOT right here. Anyone know what's going on? Firefox has NOT updated in at least a week or two, so I doubt it was an update breaking anything.

This morning Adblock Plus was disabled in my browser.

the message n the EXTENSIONS PAGE reads: "Adblock Plus - free ad blocker could not be verified for use in Firefox and has been disabled".

I've been Adblock PLus using for years, on both my computers. And it still functions on my Windows 10 desktop. Is this because it is Windows XP? Can I do anything to reacivate it?

I tried to add Adblock Plus again on the computer - but that did not work either. I get a message that says: "Download failed. Please check your connection' - but I am using the connection without problems everywhere else!

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 )

Firefox has taken it upon itself to protect me by disabling add-ons I've been using for a long time. One of them was my speed dial with all the links I visit regularly. I didn't ask for this protection, and I'm not happy with it. I tried going through the process suggested on Mozilla support, but wasn't successful.

Any suggestions on how to get my add-ons back?

I'm on Linux, and updated to Firefox 66 yesterday. I was looking forward to the new feature that disallows websites auto-playing videos. But I found that it's not the case. For example, https://www.bloomberg.com/news/articles/2019-03-19/how-an-extra-man-in-cockpit-saved-a-737-max-that-later-crashed still starts playing the video automatically. This is just one of the many I've tried so far.

Am I missing any settings? There was none I could find having done a quick search on the preference page.

Anyone know of a hack that will turn these off? Other threads on the subject have been turned off, with no real solution. Thank you.

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:

Adblock plus is not working anymore and my virus software is not allowed to keep me safe while using your browser.

Who da fuck thought that this new safety "feature" was a good idea? what bunch of muppets was sitting in the meeting thinking to themselfs "oh well... most of our users add-ons wont work anymore, but without actually giving them replacement options and a manual disable feature we will really keep them engaged in fun and relaxing search on the web for new ones.

this was the very best browser by a longshot for me for a long time because it did not present me with any feature that i could not turn off. now it seems the development goes to chrome and google and facebook style so i cant control all the feature anymore... if this keeps up i will sadly need to switch my browser and i am pretty sure others are thinking the same.

best regards in hopes that this safety feature will be gone soon

One main reason I am asking about this is because I have to download screenshots for a group I'm in and organise tables etc... For every photo added of games played, results etc... I don't get to see the relevant information I need to be able to download it.

I've tried uploading 2 pictures to here to show what I mean but they won't upload either even though they are under 1mb. Basically, when you click on any picture on facebook, you get a distorted version of that picture, or, there are no options available for downloading it etc.. When I access the same pictures on Chrome, I can like it, download it etc...and everything else is also listed, so I don't understand how Firefox isn't showing any of it.

As both browsers are on this same computer, both upto date etc..., does anyone have any idea why Firefox isn't showing everything ?

Your help would be appreciated immensely as this really is doing my head in :(

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?
