Firefox Support Forum

One site that I use often is only showing JSON 404 error code. The site works fine on another browser, on a cell or tablet. Doesn't work on my computer on Firefox browser. I tried refreshing the page and the browser - problem is still there.

How can I sign out of my Firefox account in browser automatically when I close the window? So that I need to login to my Firefox account the next time I open my browser.

Thanks!

Hello you good folk out there.

My issue is with facebook login. I accept cookies and then the accept cookie screen comes back, and back etc.

If I start in safe mode I am OK. I would like to start in full mode all the time!

Apple Mac, Big Sur 11.2.2 using Firefox and Duck Duck Go

I was switching my browser from Brave, a chrome based browser, back to Firefox because Brave doesn't can't run some of the stuff my uni learning management system (LMS). I tried importing my browser bookmarks and passwords to Firefox but the importing feature on Firefox doesn't show Brave as one of the browsers it can take the data from. I want to know if there's anyway I can fix this or if there's no hope for importing data from chromium browsers to Firefox.

I've been using Firefox to do my internet banking for years, but last week suddenly it doesn't work any more. I get a message saying "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

Please can someone sort this out as I rely heavily on Firefox for this purpose.

Using Microsoft Edge it all works as normal, so that is my work-around, but would prefer to use Firefox if I can.

Hello all, I regularly open up pop up windows to do my job, containing lots of column data. Until recently, the columns would squeeze down as small as they could - depending on data field and font size - meaning the bottom scroll bar was unnecessary. However, in last 1-2 weeks(?) the data columns seem happy to spread themselves out menaing I always have to scroll right to see the last few columns. Is there anything like a 'make the columns fit if they're capable of doing' command/shortcut? Thanks all.

And I have tried what others have suggested. I tried the keyword thing and changed it to false. It won't let me delete all the other search sites. Should I go back to using chrome again?

Hi all, i'm having an issue where everytime i start the browser, a facebook "tile" shows up in the first empty square in the main page shortcuts section, i disabled the sponsored shortcuts, and removed it, but it keeps coming back, no idea what to do.

I am trying to disable Firefox notifications whenever I take screenshots, and googling for solutions, I found the commonly suggested solution is to uncheck the "Pause notifications until Firefox restarts" box in Permissions:

How to turn off forever the "screenshot" splash notification

"shot Copied" window

This option is not available in my browser version; thus, I'm hoping there's a newer workaround for this.

For the last 2 months, I get this response from HSBC UK when I try to log in.

"Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

HSBC says that Firefox is not compatible and I should use Google Chrome etc.

My Teenager made some changes to Firefox settings to do some Roblox stuff. I dont know what she did and she is not sure either. since then, I cannot use Netflix. If I try to view a movie, then i get a page asking to install HTML5 or the silverlight plugin I have tried doing all the suggested workarounds but nothing works I have Chrome as a backup browser, and Netflix runs OK on chrome. I prefer to have everything on firefox as, - up to now - it does everything i want or need any advice please

Windows 10, laptop, FireFox version 90.0.2 (showing up-to-date)

Firefox browser 90.0.2 64-bit under Windows 10 build 18363.1016

There remains a blinking text cursor after mouse click in graphic environment, like if it was a text element... Two images added, an example in facebook and in youtube.

Local TV Station Radars and Bing maps will not load anymore. However, the weather channel radar does work. Weird. Running Firefox 90.0.0(64bit) on Win 10. Tried deleting all cookies and cache- no joy. Tried safe mode- no joy. All Radars and Maps work in Edge, but not Firefox. What else can I do?

Thanks!! Jon Abel

I can't access macys.com. I get the following message: You don't have permission to access the requested URL on this server. Reference: 18.1c2c2d17.1627421167.20bcf057

I've noticed I've had a number of new Firefox updates recently. I've also noticed it takes much longer to load my initial web site when I log into Firefox. That web site is my head page, MSN. It now takes much longer to load that site than before. Is it possible these updates have caused the problem? How can I see what is causing the lengthy wait time for my head page to appear. It takes much longer than it used to. Appreciate input into the issue. Thank you.

I have a laptop that I used from 2012 to 2015, and sometimes I start it up in order to check my Firefox history and find some URL that I visited once. Today when I tried that, I couldn't get the history. Ctrl+Shift+H didn't work, and when I hit the History menu, the option "Show All History" was gray. What should I do?

I opened the profile folder and saw that there's a big file called places.sqlite, which I think is the history file.

I did set up Sync once, though it didn't seem to do anything -- the history was still what it was when i stopped using that laptop. But I notice today that if I start to type in the address bar a URL that I have used recently on my present laptop, then it suggests the whole URL. In other words, it knows what I've been doing recently on my present laptop.
