I-Firefox Community Forum

For the past several months I'm unable to Login to Mozilla Foxfire from my Desktop. The URL I'm using is: http://www.my.yahoo.com - it then switches to https://signin.att.com and I get the following message: "AT&T - It's not you, it's us. We can't complete your request right now, please try again."

Regardless how often I attempt to Login, it's useless. I'm obligated to go to Google Chrome to access my Yahoo Mail & Calendar. Have gone many years without a hitch, now this. As a long time supporter of Mozilla Foxfire I would appreciate any help y'all could offer. Thank you. esaviles@sbcglobal.net

There is a preference "media.gmp-widevinecdm.visible" When it is set to true we can see the Widevine addon in Add-ons and Themes. When Firefox is close the setting reverts to false and the addon is no longer visible.

Is this expected behaviour?

We cannot get Netflix to play DRM content. We are currently getting the UI3012 error. We updated the prefererence "media.gmp-widevinecdm.force-chromium-update".

I don't have a netflix account so I can't test on my PC, but setting the above preference on my PC and visiting netflix.com seems to be enough to trigger the installation of Widevine, as I have a folder called;

F:\Users\Tanya\Profiles\ownri05i.default\gmp-widevinecdm\4.10.2891.0

On my PC.

My brother, who is the one experiencing the issue, says he does not have the gmp-widevinecdm folder in his profile folder. However, before updating the force update preference he was getting the F7701-1003 error which changed to UI3012 after setting that preference.

The problem started when I updated his PC from a very old Windows 10 21H2 patch level (2486), to the current 21H2 patch level 5854 and updated Firefox 115.9.1 to Firefox 128.11.0

Will look into OS version upgrades later in the year, but for now I'd like to get Netflix working again.

I had a whole bunch of open Firefox tabs and tab groups all carefully arranged just the way I wanted, then somehow a couple of tabs got moved to a new window (don't know how that happened, I didn't click the "Move Tab" and "Move To A New Window" menu options), and when I was trying to figure out how to move them back (not possible, apparently) the original window got accidentally closed -- and with it all my tabs and tab groups! When I reopened Firefox they just weren't there. Aagh! Clicking on History just shows the last tabs I accessed, not the full arrangement of groups and the many other tabs I haven't accessed in awhile but want to keep at the ready.

Can I get all that back? Or was relying on Firefox to organize my online work a bad idea?

starting at the update before the most recent one (currently june 30 2025) my firefox browser on my windows 10 pc simply doe not work at all. i am surprised it actually loaded the support page allowing me to write this, but every other page i try to open gets stuck in infinite loading. next thing i am going to try is uninstalling/reinstalling I GUESS. firefox on my other PC and phone are totally fine. is this bc i am running windows 10? please help :C i installed chrome and its absolutely awful

So, I was using "Firefox Color" to design my own theme. All the block colours seem to work. However, there's an option for custom background, which the preview within the creator app shows nicely. When trying one image type, it notified me that it wasn't compatible and to choose another. So the one I chose should therefore be compatible and therefore would assume it should work. Yet, when the theme is applied, the custom background isn't there, just the block colour. Perhaps the block background colour is overriding the custom background? If so, though, I have no idea how to stop it from doing that so that I can actually see my custom one. Plz halp!

Suddenly they broke after the 140.0 update, but as it turns out, this is the case everywhere. Does anyone know what the problem is?

Verified on: Firefox Desktop, Chromium Desktop, Firefox Mobile Font: Calibri (No changes), Roboto (No changes) I've scoured half the internet, as if I were the only one with this problem...

Sir ,recently I had problem with browsing of fire fox can you please restore my firefox to its earlier glory with no problems for browsing ans choosing bookmarks as I like ? Please restore all my previous bookmarks by importing or in any other way.

I suddenly have random bookmarks along the top of my screen, just below the Google search bar. I cannot figure out how this happened or how to undo it. I HATE this and have already wasted a huge amount of time. Please tell me how to get rid of this plague. It seems to happen only when I open a new tab, but it is really annoying.

I recently found that I could not log into the Freecycle website using FireFox but I could log in using Chrome. The difference between the two was a revision to the login page which appeared on Chrome but not on FireFox. I contacted Freecycle and they advised clearing the cache, restarting FireFox and trying again. It was still not possible to login so I tried clearing everything I could find but nothing worked. I tried disabling my protection software, Webroot and Malwarebytes, but again no success. Whatever I did I still got the old login page. However I started the Firefox private browser and it was then possible to log in to Freecycle. Can you please explain what is going on? John Rieley

I think I am in he correct forum - my apologies of I am "off base" but I am ignorant of computer technology I use an accounting software "reckon" - a programme that originated in America I run firefox as my default browser I run my E mails through G mail

I send invoices from reckon in PDF format attached to an e mail created in Reckon to my clients. Everything ran perfectly (and has done for years) on April 1st. Last week Reckon failed and told me I had the password wrong. (This is rubbish - as nothing has changed) After a week of talking to Reckon help desk I was told that it was Firefox/Gmail who have changed the system and will no longer accept third party interactions. (I think that is what he meant)

Can anyone give me a work round?? Other than printing and scanning and sending manually - I did this yesterday and the time it took was just mind boggling. Many Thanks for any thoughts - as I am not technically minded please be simple in your responses

90% of time I cannot connect to a website unless I go into settings, privacy security and clear the data. Sometimes this doesn't work and I have to go to a different browser. I don't have this issue with other browsers. Why is this happening?

Since the most recent update a few days ago Firefox (on my desktop PC) has been looking and behaving differently. The bookmarks sidebar has disappeared and can't be brought back in its previous form. Selecting Bookmarks toolbar - always show' does nothing. There is no 'Back' arrow to return to a previous screen. I'm finding this new version almost impossible to use. Have I done something wrong? Can I go back to the previous version of Firefox? Regards, Peter

I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N

Hi, Re Firefox browser how do you get back 2 windows with tabs that disappeared when restarting the PC. They are not in history anymore at all, they are gone. What opened up instead after the restart, was 2 lots of Windows & tabs that just disappeared in the same way, from 3 years ago, & they reappeared on the browsers. Can you tell me what is going on please & how to fix this problem in losing them in the first place? This problem has happened several times before & is very upsetting. Can you help in finding my recent loss of windows/tabs please? Regards Doug
