Firefox Community Forum

Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

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

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude

Hey, this has been going on for a few days, but when I try to use twitter on desktop, there are no retweet/like/reply buttons. This problem doesn't exist on Chrome or the Mobile app. I can reply to things, but that's it. I also can't browse through my notifications without the page immediately displaying the "Something went wrong. Try reloading." message. I'm not sure what's causing this or if it's just me or what.

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

For a while now (can't remember when it started) rendered graphics and text on FF is fuzzy. Examples of this can be see on Google maps, Miro, Powerpoint etc. On Chrome, Edge etc the rendering is sharp at all zoom levels but in FF its fuzzy until you zoom in.

Viewing on a 4k monitor, running 115.0.2 (64-bit), using the Windows store install Hardware acceleration is turned on. Tested on multiple PCs, all Windows 11

Attached images which shows the comparison between Firefox and Edge Both browser windows are the same size and the default zoom (100%) Examples attached are for Miro and Powerpoint

So I'm using firefox on my old PC and want to export the login data to my new PC. Firefox has export passwords to CSV but there is no import CSV in firefox on the new PC. There's import HTML but... firefox exported to CSV not HTML so I'm really confused, why would it export to a format that cannot be import?

OK I am not sure this is a Firefox issue but my g-mail account is sending composed messages to the TRASH folder. I have been using Proton Mail and have a number of email address depending on who I am emailing

Tried a few changes to my g-mail account disabled IMAP and POP that did not work I have a number of blocked email address did not delete these

Is there a shortcut to deattach tabs from one browser window so it turns into seperate window, so that you don't need to deattach tabs with clicking and dragging them with mouse?

I am very happy with the upgraded Firefox library. It works great except for one feature. Maybe there is a setting for it that I have missed.

When I click on an item in my library to open it, it opens it over top of the right-most tab that I have open. That means I always have to be careful to have a blank tab open, otherwise I lose the last item I was viewing. Is there a setting, or can you add a setting, to have the library open links in a new tab, or if one prefers in the existing tab? I want to be able to open in new tabs.

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

I am receiving the message Did Not Connect: Potential Security Issue ... requires a secure connection ... when trying to access my Shopify website AngelFallsHomes.com. This ONLY happens with Firefox; all other browsers are working fine. What do I do to fix this because obviously it is a huge concern.

I cannot log into New York Times via Firefox - ms says it thinks my IP is a bot. Also blocked on a local newspaper Montreal Gazette. I am able to log in w/ no prob on Opera - please advise? thanks!

Hello

I'm trying to sign into a Microsoft 365 email account but can't get beyond a screen saying "To use this site, you need to change your browser settings to enable DOM storage or cookies."

I've enabled DOM storage and cookies but no difference. I've cleared cookies and no help. I'm running Firefox 115.0.2 and Linux Mint.

Is part of the problem that I hate Microsoft and they know it?

Thanks

I recently started experiencing errors for logging into third-party websites that use Google sign-in.

On one site (coches.net), I have the sign-in popup loop for like 3 times and then disappear but leaves me unlogged.

On the other site (etoro.com), the sign-in popup shows but then I get an error message from the site about the login. Then it won't let me reconnect since CloudFlare won't accept my "I'm not a robot" prompt and keeps reloading the same page.

This started happening yesterday. I'm not aware of any Firefox or Anti-Virus updates that have happened since, measures not existing yesterday.

I can sign-in correctly from Chrome with no issues.

Hello, so i have a hp laptop running on windows 11. I have 2 different wifi sources here at my home, one of them is a DSL zyxel modem from century link & the other is a Verizon internet gateway that runs off of cell towers. I recently logged into both of them to configure some of the settings etc. and in the past when i only had the DSL wifi, i would log into it via file explorer>network>network interface and then select the router & would automatically be taken to the login page. For the verizon wifi, i had to go into the browser searchbar ,while being connected to that network, and enter the default IP address of 192.168.0.1 and it would take me to the login page. I first logged into the DSL network and then for the first time ever, into the verizon one, and now when i try to login to the DSL network via my traditional method & also by inputting its IP address into the searchbar (both routers have the same default address to access setup), it takes me to the verizon login page regardless if im connected to it or not. If i input the DSL modems IP address into Edge browser while connected to it, it takes me to the correct login page for that network which leads me to believe that somehow something is messed up with my firefox browser. Ive already tried going into the saved passwords and deleting the saved verizon login info. Any other ideas as to what it could be? Thanks, JD

Somehow this en.softonic nonsense has made it into my windows notifications tab under 'firefox' notifications. How can I get rid of it? I can't find it in the General, Add-on or Extensions settings of Firefox or Windows Uninstall to turn it off or remove it.

How can I get rid of it? I don't want it.

Thanks
