Firefox Support Forum

When I want to publish an ad with Mozilla on the wall site, it gives this message while receiving ... Exception calling application: unsupported operand type (s) for +: 'NoneType' and 'str'

Hello,

I have been a long-time FF user and have been generally well satisfied with it.

I have also been a long-time user of RT.com for news & opinion so I was dismayed when in April 2019 I could no longer access RT from my FF (V 26.0.1). This was a major inconvenience to me although I could still access RT.com via the FF V 81.0.2 which I run separately, I could not store links its links with the Tab Groups option I use on my older FF version.

Note: I use an outdated version of FF in order to use the Tab Groups add-on V 1.0.2 which I've used since making FF my browser since the versions available on FF Quantum are profoundly inferior to it and don't allow access to literally 10's of thousands of my stored .json files from the older program.

Happily, in January this year I found that access to RT.com via my old FF had been restored… until yesterday when it seemed only intermittently available, and today, appears inaccessible.

I am writing to ask why this has occurred and what can be done to restore access to RT.com via my FF V 26.0.1.

Thank you.

Starting 24 hours ago, Firefox loads a blank Facebook page. Whether using my homepage bookmark or simply entering http://www.facebook.com, all I get is a blank page.

I've tried: Starting Firefox in safe mode, Clearing cache and cookies, Deleting/reinstalling Firefox, Restarting my router.

Firefox opens all other websites without issue. Chrome opens Facebook as expected. I'm using Firefox 81.0.2 (64-bit) Windows 10 Home 64-bit Version: 18363.1139

I've tried reading through the over 2,000 "suggested" help topics related to Facebook loading a blank page, but none of the ones I read address this issue. What am I missing?

Thank you in advance, Don

I have recently updated to version 81.0.2 of Firefox, and have noticed that for some reason, twitter will randomly sign me out for no reason even if I don't sign out of the site when I close the tab, forcing me to sign back in every so often. Curiously, something similar happens with gmail, as it will make me sign in both of my email accounts, even though normally when I bring up the gmail website it usually just asks which account I wish to sign in to. I have not cleared my cookies in the last few days, nor my cache, so this shouldn't be happening. What exactly is happening here? I didn't have this problem in the previous version of Firefox. Can anyone help?

I'm unable to open google documents in the Firefox browser. I had the same issue in Google Chrome and contacted the support, and it was associated with an extention that allowed offline viewing of the document. Unfortunately, the issue persists here, and I don't know how to fix it.

I am not able to login icloud.com and pass 2 step authentication process. After filling up login and password, message "Failed to verify your identity. Try again." appears. Althrough in mobile phone message with code appears. Firefox 82 unable to change from icloud login page to code input page for authentication.

Tiktok and YouTube bypass my Firefox autoplay settings. By default, I set Firefox to disable autoplay of audio and video. I seldom use the website, but when I do, it blasts music at me the moment I visit the site. As a headphone user, that's really annoying!

To a lesser degree, YouTube does as well. If I'm not subscribed to a channel, it will autoplay the channel's featured video on the Home tab. Example: https://www.youtube.com/user/carolinaeyckvideos

Проблема с поддержкой сертификатов безопасности возникала и ранее: Firefox не корректно подбирает сертификат для соответсвующих защищенных сайтов в автоматическом режиме. В последнее время использовали ручной выбор сертификата, т.к. зачастую Firefox подставляет первый из импортированных сертификатов. Теперь в версии 81.0.2 и ручной выбор не работает. Был момент, когда Firefox выдал окно с запросом сертификата, но был выбран "не тот", который нужно. При повторных запусках - данное окно более не появлялось (почему?). В настройках безопасности - Сертификаты - установлен режим "Спрашивать каждый раз" но окна с выбором сертификата не появляется. Firefox отправляет первый попавшийся сертификат, сервер его не принимает, возникает ошибка защиты. При этом те же самые сертификаты работают без проблем с теми же страницами в Gogle Chrome и Opera как в автоматическом, так и в ручном режиме, и подставляются корректно.

"Microsoft to-do" isn't loading correctly on Firefox, it's stuck on a spinning wheel, however it works on Firefox private.

I've cleared cache and cookies but this hasn't helped. Enhanced Tracking is off for this page, there are no extensions on my browser.

All other Microsoft apps work correctly, it's just this one.

What else can I try to fix this?

I have been using Firefox to log into the ADP site ever since my company changed to them.

Firefox version 76.0.1 (64-bit) will no long log into https://workforcenow.adp.com

Not sure if this was after an update or not. It has worked until a few days ago. Chrome and IE works, but not FF.

ADP gives no errors, just comes back to the same login screen.

My Facebook page is blank in Firefox. I have purged cookies and cache. I have purged Firefox from my computer totally and reinstalled and the problem persists. Safe-mode does not help. I can see Facebook fine with chromium. It is a Ubuntu 20.04 system.

Hi and sorry for the vague subject line.

Here is the situation. On one page of the site an iframe is rendered. The src element of the iframe is a local url. The src url will render an html page which is simply an html form that posts to a remote url. The remote site will do some internal posts and then finally sends a get request back to my app. The final step is to render a local page from my app. All that should happen within the iframe.

With Firefox the final page is not rendered. I can debug the site and I see the final get request is processed on the server but Firefox doesn't display the page. I've tried returning a redirect to the final page instead of returning the html and then I can see in the dev tools a get request to that (local) url however I just get a blank page in the iframe.

All this is using https urls. Any suggestions are appreciated.

Thanks. Sean

why does firefox take "https://www.msn.com/de-de/" when i type in msn.com? which is foriegn language?

For some strange reason Firefox is not logging me into my favorite websites automatically any more. I have to manually log in every time. The websites' login pages are automatically filled when I move the cursor to the Username and Password fields, but I still have to click Log In. As soon as I log out and log in I am asked to "Sign In" again. I tried manually adding a website to the "Saved Logins" but that did not help. Using Windows 10 64bit.

My church website doesn't function when I open it on firefox unless I open it in private browsing: None of the tabs that open other pages appear and videos that are posted are listed but do not appear

I used to type (for example) amazon into the address bar and it would go right to amazon.com. Now it goes to a search page where I can click on amazon.com. Why add this extra step? This is so annoying!!!
