All my attempts to pay online with 2 out of my 3 cards have failed in the last 2 weeks. The Mastercard says it has connected to my bank and I'll get an SMS - but the SMS never arrives, and when I phoned my bank, they said they had no authorisation attempts reach them at all! The Visa card simply says it failed at the first step, without saying why or serving up the usual security dialogue. (The other Visa card just works).

I suspect the Autofill may be the problem here. I've recently had other scenarios where FF filled in a field for me, but the Javascript behind the website refused to accept it, eg saying it wasn't a valid phone no when it clearly was. The only way to get round this seems to be to type in the complete value yourself, which rather defeats the object. It could be something else, but it's clearly dependent on which software's running behind the card, as the third card succeeds.

I am attempting to copy a FF profile from a Windows 11 machine I created it and am using it on to a brand new windows 11 machine on which I have also just installed FF on. Both machines are at FF 150.0.3. I have done a search online for the methods to do this but they have both failed for me.

The first one I tried was simply copying the profile from the existing (source) machine to the profile folder in the new machine however FF never recognized the copied profile on the new machine (I am using profile manager on both machines).

I then tried copying the profile using the method we used to use a while back to copy profiles which is to let profile manager create a new profile in the new machine, open FF so that it creates that new profile in the profiles folder then delete the contents of that profile leaving it as an empty profile (with the name of the newly created FF profile). Then, I selected and copied the *entire contents* of the source profile I was trying to copy and pasted them into the newly created profile I had just zero'ed out on the new machine so that the new profile now had the exact same contents as the source profile. I knew this copy was successful because it took a while to copy all of the data from the source profile to the new profile and the indicator showed it copying.

Again, FF did not recognize the new profile when I opened FF with the name of the new profile in the prof mgr.t.

Could someone tell me what I am doing wrong or what the problem may be? One problem I had when I first copied the source profile to my 32GB USB drive was a message saying "inbox folder is too big for destination system. " The source profile is 12.72 GB so there is plenty of room on the USB drive for it to fit. I have no idea why FF would have an inbox file so I just skipped it. The rest of the profile copied to completion once I did that but its size after copying was now only 7.65 GB, about 5 GB less than the original. Could this be my problem and if so, how do I fix it? Thanks for any help.

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

This past Friday morning, May 29, I tried to access www.healingwell.com which I have always been able to do. But this time Firefox gave me a red screen with message: "Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience, for example, by changing your homepage or showing extra ads on sites you visit." And same message again over the weekend. But yesterday, Monday June 1, I was able to access that website, and all seemed normal. Why did Firefox give me that message on Friday, but not yesterday or today?

I edit a newsletter substack and sometimes I have links embedded in it. Mozilla denies me access to those links when I check the newsletter. Do I have to cancell Mozilla protection to have full access to the links in my newsletter from substack?

I don't know why Firefox made my homepage so messy, with so many junk suggestions. It used to be a lot of thoughtful / interesting stuff about science / nature / health / politics / philosophy think-pieces and now it is all just "(unkown celebrity name) clashes with (council) over (something I don't care about)" or "(american president) shocks defense community with late night Truth Social Screed (BROUGHT TO YOU BY TABLOID PAYWALL)." Everything is suddenly UK only, and it is all from the Metro, the Mirror, the Independent or Sky News. I never, ever read any of that. I am sometimes in the UK, but not now. And my VPN is never set there.

I don't want to block whole themes - Health? I might be interested in some of that, but I don't need ten stories from the UK health sector gumming up my feed every day. Food? I used to occasionally get good recipes on the home page, but now it's a whole section of choco-banoffie protein smoothies and fried chicken, which I would never, ever click on or prepare. Money? All of these things have potentially interesting options, so I don't want to block them, but I'm definitely not interested in getting loads more of any of it.

Is there any way to go back to region neutral 'this is interesting' stuff? I find the current home page to be really unpleasant.

Privacy Policy from TD Bank (https://easyweb.td.com) appears at the bottom of every page change, no matter if "Accept All" has be selected. Moving from one account to another causes this pop up to appear. This does not happen with Chrome. With Chrome, one "accept all" has been chosen, the pop up no longer appears

If I turn off Enhanced Tracking Protection the problem seems to stop.

Hello! Is it possible to recover older open tabs from a broken device that had sync activated? For a while they appeared in the hamburger menu in the top right, but now they suddenly disappeared, and under the "connected devices" I cannot click the device or anything. It went broken 2-3 months ago. Best wishes!

Hello brothers and sisters, i am need help! I'm experiencing performance issues when surfing the 9GAG website. The amount of RAM consumed by this page is growing exponentially. It's gotten to the point where this tab can consume up to 5GB of memory, and that's not the limit. This issue hasn't happened before. I can't figure out what's causing it.

What I did to fix the problem: I reinstalled the browser. I reinstalled add-ons. I reset my old profile, saving only bookmarks and passwords. I reinstalled the operating system. None of this helped. However, my friends don't have this problem with this site. Please help.

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Prior to the latest release I could easily log into the site https://fun.chicagotribune.com/game/tca-jumble-daily. I can login in but once at the player page I must enter command shift R to reload the page afresh. The response is very slow relative to the previous edition of Firefox. There are other examples I could site with similarly odd behavious. Just today I tried to make a reservation with resy. I got a total runaround to my entries. I eventually gave up and used Safari and everthing proceeded as expected and I made my reservation.

성인사이트가 크롬과 엣지에서는 정상적으로 열리는데 파이어폭스에선 보안 연결 실패라고 뜹니다. 원래 파이어폭스에선 성인사이트를 차단하고 있는 건가요? 아니면 차단을 해제할 수 있는 방법이 있는 건지요 Adult sites open normally on Chrome and Edge, but on Firefox it says security connection failure. Is Firefox originally blocking adult sites? Or is there a way to unblock it
