Firefox Support Forum

I try to login on Firefox or google the the sight of "sigsauer" but I get a forbidden you don't have permission to access this resource. I can certainly use safari. Why can't I use google or firefox

Good morning :-) All of a sudden my gmail no longer opens in Mozilla Firefox. All other sites work, and my gmail works in Chrome and Safari. I don't like to use any other browser. I've tried the bookmark and went outside the bookmark, and neither works. It just spins and spins. Can you please help me?

How do I update Firefox? Or is this system out of date? I run OS X Yosemite 10.10.5

Hello,

I'm looking to download and run the most most recent version of Firefox that will work on a Mac running OS 10.10.15. Where can I find it, and is there anything special I need to make it work?

Thanks in advance.

From my adobe account, I try to launch my web based apps so I can use the web based adobe acrobat, and the browser page opens as a blank screen only. I am on an older mac book w/ Yosemite 10.10.5 and Firefox is up to date wiht 78.15.0esr (64-bit). Please help! I need to be able to manipulate pdfs. Thank you
