I am using the same account (my school email), and everything else sync successfully.

Tab groups saved on my Windows PC didn't show up on my Macbook; tab groups saved on my Macbook didn't show up on my Win PC. Is this a feature or bug?

Hello, I recently learned that browsers will condense spaces written in HTML down a single space. As someone who thinks putting two spaces after a period is more legible, I was wondering if there is a way to disable this, either in settings or with a browser extension. I know this will result in a less consistent browsing experience because not everyone types this way, however it will make my browsing experience better when reading things written by people who also believe in using two spaces. Thank you.

Hello, I am using mozilla built in VPN but I have an issue as for some sites my internet download manager can't download videos while it can when I use my other VPN app.

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

Hello, I am facing a very strange and frustrating issue with my website https://biografieblick.de/, and it is only happening on the firefox browser other browsers like chrome, edge or safari are loading the site perfectly fine. The Issue is it occurs occasionally, Yeahh IDK why. When I try to visit my site, Firefox gets stuck on a screen that says "Checking if the site connection is secure" and it looks like an loop sometimes.

This looks exactly like a cloudflare turnstile loop but I am NOT using cloudflare. I have double checked my DNS records and explicitly confirmed this with my web hosting provider. This block only triggers when using firefox.

I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

When there is a field to fill in my credit card info, the info will appear and let me select the CC I want to use but when I move away from the field the CC info goes away.

Hello,

I am returning to Firefox after many years and have recently reinstalled the browser. I logged into my old Firefox Account, but it immediately started syncing my old data (passwords, bookmarks, extensions) from years ago, which I no longer want.

Here is my dilemma:

I cannot simply turn off Sync. I want to use Sync for my new data (new passwords and bookmarks) moving forward, so keeping Sync enabled is necessary.

I cannot find an option to manually delete old data on the Mozilla account website. The "Delete Synced Data" option mentioned in some older guides does not seem to appear on my current account management page.

Is there a way to completely wipe the historical Sync data from the Mozilla servers so I can start fresh with a clean cloud, while still keeping the Sync feature active for my future data?

Any advice or solutions would be greatly appreciated. Thank you!

12 hours ago Firefox stopped working .No reason ; no changes just the following message including access to this site.So now I have to access with edge . Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
