I cannot connect with my on-line banking site. When I try, I get the message "Bad Request--Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. I am able to access the site using another browser, so there cannot be a problem with the site itself. This situation has only existed since Firefox did an update. So, the problem must lie with Firefox. If it is not fixed, then I fear that I will have to discontinue using Firefox as my online browser. Please have someone from technical support contact me. [edited email from community support forum]

Copy & Paste stop working on my Firefox. How can I get it back? It does work on Chrome but I prefer to use Firefox. You can email me at [edited email from public community support forum] TIA, Barry

I am interested in going to Windows 11, but I don't know what procedure to use to do that; all the info is confusing To me, the info makes it look like I need to buy another Computer, even though I have a perfectly good operating DELL Inspiron 1 that is not that old, 4 years old with a new hard drive.

Hello- Wondering how to turn off the "skip to main content" that continually pops-up on some web sites. This is a problem on a single Firefox installation and I cannot figure out which setting this could be.

Thanks in advance! -BD

Now that my browser is Firefox I cannot get to my email or anything else on my computer. What must I do??? At one point I was signing in to Mozilla Firefox and it said that account already exists. This is very frustrating for an older geriatric. Please send me instructions to get back where I was. My present email address is [edited from public] @gmail.com.

Can we get a setting that disable the Quick Find feature or at least its keyboard shortcut.

It breaks keyboard shortcuts on multiple sites, as it is often used to select the search bar(Youtube, Github, ...)

'I am posting this for a third time, because I am absolutely sure it is caused by the latest Firefox update.

I am typing this into Notepad and copy/pasting it to the text box on the site.

I am legally blind, and I am very dependant on the Windows Magnifier. Yesterday I took the latest Firefox update and after installing it, the Windows Magnifier will no longer follow the text cursor on web pages rendered in Firefox. It will follow typing in the address bar and the search bar on the task bar, but it will not on web pages rendered in Firefox.

I do not have this problem with Chrome or Librewolf.

I had made two earlier posts with no response from Support. I have been trying desperately to figure out what waws going on as I was moving links, bookmarks & passwords into Librewolf.

I tried to refresh Firefox. It didn't work. I tried safe mode. It didn't work. I even tried a different profile. It didn't work. I even tired uninstall & reinstall Firefox. It didn't work.

I even called the Microsoft Disability desk and had them check my magnifier settings, and they are fine, and yet even if I toggled them on & of--it still didn't work.

So finally, out of desperation, I did the dreaded System Restore.

I rolled it back to August 18th and sat and waited.

And though I had to relog into Firefox--it worked!

and i have been surfing happily all evening until I loaded the Spotify player page and it wouldn't play. Okay this was weird because I had been using it all week and suddenly it wouldn't play. I did a search, and apparently it wasn't just me. I opened the About Firefox and there it was--the dreaded update.

Believe me, I really didn't want to restaret the browser, but it was doomed to happen anyway.

And guess what--the Windows Magnifier view won't follow the text cursor in web pages rendered in Firefox--Again!

The Spotify player plays again but.....

If you don't believe me, open the Windows Magnifier, dock it on your task bar, and try to type into a web page. The view just goes cockeyed.

So yes, the update has a bug. And for all the people who are visually handicapped and use the Windows Magnifier we are cursing you right now and hoping for a quick fix before we all have to move to Chrome.

You sighted people have no idea how frustrating this is.

At least I'm glad it's not my PC.

But if it doesn't get fixed, I"m absolutely done with this browser. It is now unusable for people with visual disabilities.

Good luck.

Thank you. '

Hi, I was asked if I could contact you by google disability.

I'm having a huge problem creating a channel on youtube with a live.co.uk account when using NVDA.

I press b until I hear account menu button button submenu, pres enter or space, then arrow down to create channel and press enter. Nothing seams to happen.

Google disability has shown me a couple of video or audio files proving that it can be done, they've even said that they tried creating an account with an outlook account, what live.co.uk is called now from my understanding.

SO I'm really confused as to why they can do it and I can't.

I can't show you with OBS because it messes with my screen readers speech so if you have another way I can show you; please let me know.

I've already tried the following, suggested by disability support: 1. uninstalling and reinstalling firefox.

2. making sure addons are disabled, the only one I left enabled was a volume booster but I doubt that would be the issue.

3. Setting NVDA back to factory settings and disabling all addons.

This has been confusing me on and off for up to a year now.

I love FF and I appreciate the intentions behind the new update for quick/custom search engines in Firefox 140, but I can't help but notice that the new UI for custom search engines requires the user to manually click on various buttons and does not allow one to navigate the process via keyboard only. (Unless I'm missing something?) Prior to this UI update, I was able to fully navigate the drop-down and select my custom search engine of choice using only my arrow keys and enter key. Now, the "search with XYZ" button that pops up if you type the site name is only selectable if you click on it, and cannot be highlighted with the arrow keys.

I am not personally disabled in a way that prevents me from using my trackpad, but having to stop what I'm typing and go out of my way to click on various UI elements is a real stymie in terms of flow, ease of use, and efficiency. At least for me.

Is there some kind of secret key combo I can use? Or an about:config setting to enable keyboard navigation in custom searches? Is it a bug? Or simply the removal of a feature?

I hope I will be able to use my arrow keys to select my search engine again in the future— Thanks

All of a sudden, the text in my Bookmarks bar has turned black making it unreadable on the black background. Any idea why this happened and how I may revert the text back to white? Thank you for your help.

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

F12 opens the inspector - How to change th eshortcut of remove it completely

F12 is near the backspace key on my asus laptop and I keep accidently hitting it and would like to remove this fuctionality. I can just use ctrl shift c if I need it

My sanity is at stake here!

Я пытаюсь использовать сочетание клавиш ctrl+shift+c, что бы скопировать текст, но, вместо этого открывается devtools, я не могу использовать другое соччетание, пробовал отключить это в настройках devtools, но это не сработало, так же пытался выключить devtools, но не помогло

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.
