Why am I getting the message below every time I try to go on the The Great Courses website? The Great Courses Customer Service Dept it is Firefox that is blocking me from accessing their website. Please tell me how to correct the problem.

"You don't have permission to access "http://thegreatcourses.com" on this server.

Thank you.

How do I get sound back on the add on extension "Check4change" ? it has always worked and then stopped one day. I have tried all the suggestions of reloading the extension and even removed and reinstalled Firefox, it was no help. I have sound in Firefox, just not while using the check4change add on extension.

How do I recover sound while using the extension?

I'm using Floorp and its working perfectly aside from this one or two pixel thick line of white that completely borders the left side of my screen every time I open the Browser. Is there any way I can fix this?s

When I open my youTube home in Firefox browser is completely blank nothind is showing I don't have this problem in other browser. I have tried in the settings to turn the history on and off but nothing has changed.

There has to be a way, but I can't find it. How do we enlarge the font size for tabs, toolbar, favorites, search bar etc. I like that we can customize the colors but the font size seems to have been left out. I know we can ctrl + to enlarge what's in the browser window but this has no effect on the actual browser fonts. They are wayyyy to tiny. Is there a fix for this?

Firefox will not run on my Apple Desktop any more. I have re-installed several times - still comes up "not responding" and I have to force quit.

I am running OS 12.7.5

I am using a primary password. However the password is required when I open Firefox as well as for password protected websites I visit. Is there a way to not have to put in the primary password every time I open Firefox? I feel duplicate protection is unnecessary and time consuming.

Thank you.

I cant log into x.com. Whether tracking is set to strict or not. I just get the same error. I have tried re-starting my browser and computer. I currently have it set to strict and have it turned off for this site. Why cant I go to this web site?

no matter what i do, every website is now dark. I want it turned off and it won't. Since this can't be turned off, how do i switch all my bookmarks to another browser? Chrome, yahoo, etc all of those don't have the dark background

I run G-mail in a Firefox tab. It worked perfectly until 48 hours ago. Now I cannot attach any files to my emails, and Gmail's "Help" is useless. Is there anything in FF which could be preventing this? Any clues as to why GM has turned nasty?

Recently I have been getting this message and being blocked out of sign in ability at some sites after the last update. Error: Google reCAPTCHA verification failed, please try again later

How do I get rid of this? Please be specific.
