After last mac update i have not been able to get onto my Farmille2 game ive been using firefox on my macbook air no matter what I have tried hasn't worked going directly to zynga just brings up chrome info which doesnt work can you please help ?

I cannot get into my online accounts, as I have always done for years. After I select the site, the screen looks like it is working, but then a new empty window pops up: the tab says "citi 400 Bad Request" At the top of the empty screen it says: Bad Request. Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I want to remove Paypal from my Mozilla VPN subscription and add a credit card, but I can't figure out how to add a payment method.

I tried removing Paypal, but it forced me to restore Paypal as the payment method.

How do I switch to a credit card?

I've suddenly had an issue crop up when trying to access Twitter on Firefox. I get an error message that says "Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com", but the problem is Im not using Strict Mode. I have standard protection on.

Getting around 20ms for DNS lookups so thats not the issue. Why do I see Error Code: NS_ERROR_OFFLINE maybe once every several days when this Firefox has never been in offline mode and never will be? Env is MacOS 26.5.2 with current Firefox installed.

Hi, My browser won't save the open tabs. I lost my tabs multiple times now, I don't even bother opening them back up now, but it's annoying. I have activated ( and disabled/enabled ) the setting to open previously open tabs on startup.

What can I do ? thanks

I am suddenly getting ads across websites in Spanish, and my Amazon account flipped to Spanish. I used several IP geolocation services which identified my IP address is assigned to Mozilla Corporation in Queretaro, Mexico, despite my Mozilla VPN being designated United States. How do I solve this problem?

This is a recent problem but when I try to open new tabs they don't load or take a very long time to load. I wind up shutting down my computer and resarting but sometimes that doesn't help. it seems to be getting worse. I do not use any other VPN but yours and Duckduckgo to search. I use a macbook air. Any suggestions? Thanks

Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!

When a link from outside Firefox opens the desktop browser, it displays the default home page but does not continue on to the URL specified in the link. This is new for me in V 152.0.6 (aarch64) . Mac OS 26.5.2 (25F84)

unable to load X.com. Shows Firefox Enhanced Tracking as "strict". in FireFox settings, it show i'm at "standard, not Strict". Have refreshed tabs as instructed. No change. Still cant load X.com.

When checking out the new features the ' Learn More' link under Tab Groups directs to the article explaining Pinned Tabs, there is no way to get to the explanation about Tab Groups

http://www.portal.lincare.com. When I typed that www. and it shows firefox cannot open it for me to order the supplies for my CPAP.
