"Server Not Found

Firefox can’t connect to the server at info.bnf.fr What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi."

I've spent a lot of time doing all this, to no avail. If I change browser I don't have the problem. I've been using Mozilla browser since before Firefox was invented and never had a problem before. You've changed something in your latest upgrade which has caused this problem.

I am unable to download a bank statement pdf from my online banking, using Firefox. I AM able to downoad it using Google Chrome. I am able download OTHER pdfs on Firefox - just not my bank statements! I HAVE been able to download bank statements successfully in the past, using Firefox, but now am unable to. When I try to download statement from the bank website, firstly I get a black screen with small message saying "No preview available", and an invitation to download. On clicking Download, I'm taken to a white page saying "Error No API key found in request. request_id: a2ad87061f2bed614b1d53708d35cb26", but no further options. I've exchanged messages with my bank, who've found no solution, and advised me to look into it with you guys - ie, Firefox browsing. I've played around with Firefox settings, cookies, security settings, etc, but all to no avail.

Any clues how I can resolve this?

Seit kurzem kann man in der WhatsApp-Web-Version keine Bilder mehr einfügen. Es erscheint nur ein schwarzes Feld. In Chrome und anderen ANDROID-Geräten funktioniert das. Nur nicht in Firefox. Die WhatsApp-Hotline schreibt, dass es an Firefox liegt.

YouTube is playing 4K videos like they are in slow motion. If I lower the quality they work fine, but switch back to 4K and it's slow motion stutter-fest again. I have seen several topics about this but it's still happening to me despite all of the "fixes" I've tried. This is a list of everything that I've seen and tried, and not a single one or any combination of them fixes the problem for me.

In about:config I tried changed the following to False: gfx.webrender.layer-compositor media.av1.enabled media.wmf.dxva.d3d11.enabled

Tried uninstalling all extensions.

Tried a complete uninstall and reinstall of 149.0.2 with a fresh profile instead of updating from 148.0.2.

Tried installing uBlock Origin and used the following rule: ||www.youtube.com/web-reports$xhr

Tried unchecking the uBlock "Quick Fixes" filter.

Tried disabling hardware acceleration.

Tried disabling DNS Over HTTPS.

All that said... what DID fix it was reverting back to Firefox 148.0.2. I tried again to update from that to 149.0.2 using the FF built in updater but the same issue immediately came back. Zero issues at all playing 4K YouTube videos on FF 148.0.2 or the latest versions of Chrome and Edge. Issue is ONLY on FF 149 and 149.0.2.

I have had an email account for the last 28+ years. (*.msn ) For several months, I have not been able to access my account directly on Firefox. I can access it on Microsoftedge. To log in, I enter my email address. I then enter my password. I have recently replaced an old password with a new password. Microsoft does not accept it directly. At first it (Microsoft login) asked me for the first 2 digits of my cell phone number, then a puzzle. Sometimes this works, sometimes not. More recently they have rejected any attempts because I have tried unsuccessfully too many times. That may be as few as 2 times. I have gone through several variations of solving this problem within Microsoft help. Each attempt ends at either going onto a loo[p or Micosoft asking for a code, pass key, or proof through another email I have. I have accumulated a list of codes, PIN numbers, all of which do nothing. I have been at this since 3 April.

On Firefox I can no longer access some sites e.g. IRS.id.me and some bank accts - what to fix? I have been forced to use Microsoft Edge to get access.

I have always been able to watch "NPR Watch" video clips. It was not functional on my new iMac with a new install of Firefox 149. I checked my laptop and it was fine on v147, but when updated to 149 it too was not functional. Please provide a step by step fix. I tried fixes available on internet without luck

I am using windows 11, after the latest update 149.02 I am unable to log into CIBC (Canadian Imperial Bank of Commerce) account it gives me error message 0001 with an exclamation mark on the screen, tried disabling all add on no luck,

Thank you, Esti

For the past week everytime i use the search whether by using the address bar or context highlight a word i get a blank page as first result, if i search again i get the result. I use yahoo search engine as my main search engine for the past 10+ years. This doesnt happen if i set the google engine as i tested it in case it was an search engine issue.

bold text I contacted Directv.com via chat. After trying to sign in to my account on Firefox (which was successful), I could not go to either MY ACCOUNT INFO. or any other page without being signed out AUTOMATICALLY upon clicking any further tab (such as MY TV Package). Their chat technician said that FIREFOX is no longer supported! Is there any way to fix this?

Recently (within the last month, March 2026) when pasting links into emails on Microsoft Outlook online a pop-up window appears which prevents you from continuing typing unless you manually click on the window with your mouse cursor (hitting enter isn't sufficient). This is extremely aggravating and significantly slows down workflow. As far as I can tell, this issue only happens in Microsoft Outlook. I have ensured my Outlook settings aren't to blame, in part by failing to recreate this issue in Google Chrome and Microsoft Edge on the same account with the same Outlook settings.

Here is a screen capture of this happening I recorded tonight: https://imgur.com/Qte3N6b

I have ensured my Firefox is up-to-date (Version 149.0.2 64-bit).

It looks like others have had similar issues. Some examples follow.

1: /u/TyDraniu reports this issue on Google Docs here: https://support.mozilla.org/en-US/questions/1567972. (I do not have this issue on Google Docs, only Outlook.)

2: A year ago a reddit user reported this issue and a config altering "fix" that a Mozilla engineer said was very bad advice: https://old.reddit.com/r/firefox/comments/1dofgd2/pasting_into_web_outlook_popping_up_little_paste/. (I have not tried this fix given the engineer's response.)

3: That reddit post links to a 2023 Mozilla Support thread noting that same "fix" but containing no actual solution: https://support.mozilla.org/mk/questions/1411533#answer-1579497.

Hi Team,

Since yesterday I am observing the issue while accessing Whatsapp which is asking for Quick security check with passkey and same was observed in Google which was resolved within few clicks but not Morzilla.

Currently using with Google.

Both amazon.ca and mec.ca emails do not show anything in the body of an e-mail. If I use a different browser (duckduckgo) everything is ok and I can read the whole e-mail. This only started with the Firefox version 149 but is continuing with version 149.0.2. My email is handled by yahoo.ca via rogers.com. So far I am seeing this only with the two companies listed here.

Any assistance is greatly appreciated.

Running on a Macbook with Tahoe OS. Certain websites will not display my responses to a checkmark box. Certain websites will not permit changing a checkbox default setting. Specific example: https://cards.barclaycardus.com/ has a checkbox with remember user name defaulted to a check. Attempts to click to remove the check do not work. Also, on certain websites when entering login information that is incorrect, the message indicating to correct the item(s) in red or highlighted does not display the incorrect items in a highlighted condition. In fact at the bottom of this page, the response box labeled Email me when someone answers the thread does not display a response when I click on it, even though the "response" is accepted.
