Since I started syncing Firefox on my IPhone, every time I close and open my Windows desktop Firefox, my sync account gets disconnected and I have to login in and put the annoying verification code every time. It gets disconnected only on the desktop side and not on the Iphone. It's pretty annoying. Any ideas why this happens? Thanks in advance.

Firefox is not loading on my desktop full sceen. I can see a small page minimalized when I put my curser on the Firefox icon. This has happened once before and I had to uninstall and install and I lost a lot of settings doing that. Please advise. Picture on the left is what I see, not the other.

My google search suggestions aren't working in the firefox awesome bar. Search suggestions are turned on. Opening the console gives this error, "SearchSuggestionController found an unexpected string value: Non-200 status or empty HTTP response: 403" I've tried using troubleshoot mode, making a new profile, etc. I still can't get it to work.

i can't watch a streaming movie without it stopping to buffer through out the whole movie . I never have a problem watch TV shows. It wont upload the stream long enough to keep playing . Can i increase the streaming a head so the movie doesn't stop playing till the end.

I had to do a clean reinstall of MacOS. I've copied my old profile info from Time Machine to /[user]/Library/Application Support/Firefox/Profiles, but when I open Firefox, it doesn't find the data. What am I doing wrong?

When trying to log onto YouTube on my Windows 11 laptop through Firefox or Edge, I input my name & password then Google says, "Couldn't sign you in. Google couldn't verify this account belongs to you." I was on fine yesterday. I can get on with some other gmail accounts that I have, but my main gmail account only works on Chrome now.

Respected Sir/Madam, I found a problem to use Mozilla Firefox (137.0.2 (64-bit)) on Windows 10, problem shows in attachment.

Already uninstall Firefox and reinstall it but problem not solved. After restart PC Firefox works and it browsing speed is very very slow but after close Firefox problem start again.

Please give me the solution. I am a die hard lover of Mozilla Firefox.

Hello, a locally hosted application has a web interface which tries to send a data (POST request) to a remote resource (which is under my control) yet the web browser (Firefox ESR 128.9.0esr) blocks this resource request saying in a developer console (F12) this:

• NS_ERROR_GENERATE_FAILURE(NS_ERROR_MODULE_SECURITY, MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT)

• Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://myRemoteServerIP/request.php. (Reason: CORS request did not succeed). Status code: (null).

I suspect that the CORS blocking is a result of the first (SSL) error, AI also told me that I can configure my remote server/resource (e.g., using Apache, Nginx, or PHP) to include the necessary CORS headers in its responses and indeed the remote server of mine has such lines inside a PHP script that is receiving the request: header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: POST'); header('Access-Control-Allow-Headers: *');

The remote resource (server) is using self-signed SSL certificate and it is referenced using IP instead of a domain name.

When I try to do the same request via Private browsing window (without extensions), there is no NS_ERROR about self-signed cert. but only CORS one. When I try browser Librewolf 137.0.2-1 (my FF version is older: 128.9.0), the request is NOT blocked, is OK..

My main aim is not to avoid blocking in my browser, but in all main browsers for everyone.

Is it so that this kind of blocking is default behavior in browsers? Is there please any way to avoid that, beside getting a domain name and CA signed SSL certificate?

'bold textSince Dec 2024 my Folders are scewed, not related to the folder names. Most are not accessable. Your wonderful up grades have nearly left my computer useless. I have used thunderbird for many years. Now my system is useless. I have an excellent computer, but because of your previous upgrades nothing works. My folders names don't match what is in the folders. Many folders are not accessable. I am 85 years old. I don't know where to go to get help. THis new upgrade has left me without a browser. I couldn't get on my regular Zoom meeting this morning. I;m happy some of your super techs are happy with your changes. I can't get it. One more thing my computer doesn't have. Your changes have made my computer useless. THanks! Winston Hatt john316win@gmail.com
