Firefox Community Forum

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.

Firefox version: Latest version on Mac. MacOS: Latest version. Issues: After a certain date, I did not know what happened. After that date, I was unable to drag the local files to my Synology Nas via its "Quickconnect" service in Firefox. I made several attemps trying to have this issue solved but in vain. Eventually I had to switch back to Chrome. By the way, I am able to log into Quickconnect in Firefox and delete files.

I want to move my whole folder and to backup and move it to a new PC. But it says when moving a file called activity-stream.discovery_stream I need a permission from myself.

i have been using the old yahoo for years and now it seems they changed the layout to resemble google. it sucks. if i wanted googles layout i would use my google email. if i use this term https://mail.yahoo.com/d/settings/1 i get the old yahoo setup screen and then i have to click return to mail and the old screen stays until i either restart the pc or restart fire fox. i do not see in fire fox setting an area that lets me put in a startup term like chrome has that will restart yahoo in the view i like. being that view is still there.

the old view that i like with the blue on both sides

hello! this may not be an emergency, but im still curious. will the sports widget be updated after the world cup? i think this would be cool if after the world cup people could choose a sports they want to follow (tennis, soccer, formula-1, etc.) and the widgets will show the updates of the following sport. what will be after the world cup ends?

I have always accessed my LinkedIn account on Firefox. Suddenly today, my PW does not work, and my email address for PW reset does not return a PW reset link. Cleared cache without success. I can access LinkedIn on Chrome. Can you suggest what I have done to my Firefox to cause this? Thanks!

I'm using Windows 10 on a PC. Norton Security app is preventing web browsing by Firefox. The message I get is: "We prevented your connection to ful.hartonly.com because it is a dangerous webpage. Threat category: URL:Blacklist" I can still web browse using Google Chrome without any problem. What is ful.hartonly.com and how do I clear it?

Just made a new profile and wiped everything from my history following another issue which isn't strictly speaking resolved. I am unable to load image-dense websites with any consistency. Issues do not occur on other browsers. I receive similar errors on Twitch:
