Anyone else had problems the last two weeks with performance? I'm on a macbook (Tahoe 26.3.1) and in the last two weeks tabs are constantly crashing or freezing. I have never had this before. It's doing my head in and I'm about to make the painful move over to Chrome if nobody has any ideas how to fix it?! I don't want to do that as all my bookmarks etc are set up on Firefox...

While launching Firefox VPN browser all of my bookmarks were erased. Additionally, my backup copy of my bookmark records was also deleted. I have not been able to reboot or restore the system. I need help.

Hello. I have a problem with the chat.deepseek.com website - every time I launch the browser, the language settings are reset from the system (or Russian) language set manually to English. Interestingly, this problem only occurs in Firefox, while other browsers work as expected. Additionally, the test profile created again also works properly. What I have done: 1. Reinstalled the browser, but it did not help 2. Deleted the folders responsible for Local Storage in the profile folder - didn't help 3. Cleared the cookies - helped until the first restart, then it was the same. History is enabled, and cookies are not cleared when the browser is closed. How can I solve this issue without deleting my profile? I don't want to lose my bookmarks, passwords, and website settings. Thank you in advance for your assistance.

I keep getting this message at the top of each site I go to: "You must log in to this network before you can access the Internet" It thinks I'm on a captive portal?? I'm at home on my own internet network. Why am I getting this message?

I was getting popping in audio both in Smplayer & videos on other sites. I discovered the problem went away completely when I closed the X tab. When it was open, I noticed another glitch. I keep a small video windows to keep track of my sleep time. The elapsed time is displayed on them. Only when X was open it was throwing it off by about 3 seconds a minute. I closed it in Firefox & signed onto X on Chrome & all these problems went away. This is the only web site that has ever done anything like this. What is Firefox's problem with X?

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.

How do I update Firefox on my rand McNally tablet When I factory reset it ,it went back to the original version and I can't get it to update to the version I had beforehand

I currently have Firefox 149.0.2 rapid release channel on Win10 Pro ESU.

I want to switch to the ESR channel.

How do I do that?

Is there anything I should be aware of to avoid problems?

Thanks!

Firefox for iOS. After most recent update, when I open new tabs I get

"Oops, something went wrong loading this content. Refresh and try again"

I went to settings to make sure Firefox Home was the default loaded on New Tabs, which it is. How do I fix this?

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

Dear Firefox friends, I am rather computer illiterate and use the internet only for emails and purchasing from Amazon. I have avoided installing Firefox updates, as they disable my sound and change language to Albanian, where I live, but don’t speak Albanian. Can you solve this, or will I have to just avoid installing updates? I have no concern for security; anyone can hack into anything they want, but it will do them no good; I don’t have anything that is sensitive, and my bank has everything well secured (and minimal funds anyway). Do you have a permanent solution – I don’t want to fix every update? I know you hate non-nerds like me, but I'm 80, and have neither the time nor inclination to be one!!!! Thanks, and have a great day,

Dear Firefox.

I've now got 2 VPNs. One's called Proxy VeePN (that's how it spells it!) and the other one's your new one.

Proxy VeePN lets me use Pandora Music. Your one doesn't. Pandora can tell I'm in England on your one, it can't with Proxy VeePN (it thinks I'm in Switzerland, pretty sure.)

Why doesn't your one work with Pandora? I haven't tried it with anything else yet but then I really only use a VPN for Pandora Music anyway. Sometimes there's a couple of American games I play, but mainly Pandora. Why is it Proxy VeePN works with Pandora and yours doesn't?

Yours respectfully,

Chris, Windows 10 user cos I can't afford to buy a new computer that works with Windows 11 (I know there's a registry hack but I don't think this one's fast enough anyway, was designed for XP and tends to die a death with 10, let alone 11! Too slow. The computer, not its owner!)

Yours puzzledly,

Chris.

Searches using the provided Amazon search feature found in settings will always have "tag=admarketus-20" in the url. Example: https://www.amazon.com/s?tag=admarketus-20&ref=pd_sl_ [bunch of letters and numbers] &mfadid=adm&k= [search query] Now, if this were an affiliate tag for Mozilla specifically, I would understand, but googling the "admarketus-20" tag turns up posts showing that users on various other browsers (Vivaldi, Opera, Chrome) also reporting seeing this tag popping up in their searches too. I wondered if this was due to malware, but I did a fresh Firefox installation on a newly installed Win10 machine and it happens there too. Who/what is this tag for?

Just found Firefox's (v149.0) VPN button in my toolbar. I turned it on and entered whatismyipaddress.com. I got the message

"Unable to find the proxy server. Firefox can’t connect to the server at whatismyipaddress.com"

If I turn it off FF brings up the page correctly. I get this error msg for any other urls I try to bring up. Ideas?

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?
