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.

I've installed the 10.5.x version of Network on my Ubiquiti Gateway. I now have a problem accessing the gateway. However, this is weird. When on the local network, I can connect directly to it, no problem. Where the problem comes in is when I try to connect to it via unifi.ui.com, the web portal that Unifi Gateways connect to. I've tried a Private Window which is set to not enable any extensions. The results are the same. It will sometimes load part of the page, but never all of it. Before the v10.5.x Network Application update, this was not a problem. I've tried this on both a Windows 10 & Windows 11 computer with the same results. Everything works if I'm not trying to connect via the web portal from the local network. (i.e. If I'm elsewhere or use my cellphone's hot spot, I can connect to my gateway via the web portal without any issues.)

I would blame the Network Application update as the problem if it wasn't for one detail. It does work from the local network if I use MS Edge instead of Firefox. So, I suspect that while there was a change made in this update, there is also something that Firefox is blocking that Edge isn't.

Any ideas?

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 enjoyed the functionality of the sports widget during the world cup. Are there any plans to make it useful for other sports? is there some kind of API to mess around with to build your own firefox homescreen widgets? I'd love to see MLB schedules/scores/updates populated on the new tab page.

Hello Mozilla Community!

I've been at this for about two months and can simply not find a solution. I normally have 40+ tabs open in my desktop browser. I can put my mouse cursor/pointer over the tabs and using my scroll wheel shift visible tabs left or right (not actually switching to another tab).

All of the sudden it seemed that when I do this the tabs just absolutely fly by. Like I can't shift just two or three tabs at a time, it's shifting 10+ tabs with just a single scroll wheel 'click'.

I can see ten tabs or so and I know that what I want is just a few to the right, when i begin to scroll them the tab I want goes shooting by so far left it's gone now. I 'm left having to click the left/right arrows to move just one tab at a time, but if I click them too fast I get basically the same response. They just go flying by.

How can I slow this down without also changing the vertical scroll speed of the mouse when reading long webpages?

Thank you, John

I've had a problem for a while where Firefox tells me "Firefox is being updated by another instance" and the only way I've been able to get updates is by using the installer.

In my attempts to resolve this, I learned of the `about:profiles`. I have never set up profiles so I figures I should only have the 1 default profile but it turns out I have `default`, `default-release`, default-release-1`, and `default-release-2`.

Of these profiles, the `default-release` is the 1 that has my data while it is `default-release-1` that is able to update.

I would like to make it so that I only have 1 profile that has all of my data AND is able to update.

I already tried removing all the profiles accept the one with my data but that leaves Firefox unable to update. I restored all the profiles I removed and I am back to where I started.

Does anyone have any suggestions?

Since I have been able to proceed and complete job applications to Indeed/Glassdoor in other browsers, I have to assume there is a setting somewhere in Firefox that is preventing me from completing these tasks. I would like some ideas, theories, and instructions to correct this problem sent to my email, [edited email from community support forum]. I have included some images of what I am getting. In some cases, I just get a spinning circle. In other cases, the screen goes "grey" and won't proceed. In the third example I have provided, the screen does nothing. Clicking the "Continue" button simply does nothing. It is as if the button has been rendered inactive. Thank you for your assistance.

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.
