Firefox Support Forum

I'm having a problem using my bank website with Firefox - I get a message when I move from one page to another, and that message closes the bank website - Here is the message: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." It is very important to me to be able to view my accounts and investments daily - please help me solve this!

Hey,

My name is Alex. I'm currently using Doxy.me for telehealth purposes. The past couple of appointments I've had have had issues with microphone access. Whenever I connect to the site, I get prompted to request microphone access from Firefox, but when I press the button the browser doesn't give the permission prompt. I've tried refreshing the site/browser, checking permissions on the address bar and in privacy & security settings, but there's nothing there, and I can't manually give permission to the site.

The only change I've had is that I've recently built a new PC with Windows 11, I'm not sure if there's a compatibility issue and I can't find anything about it. I've considered using another browser but I don't like the alternatives and would really like to just use my default. Any tips?

I will be moving all of my data to a new laptop and want to know if I need to have both my personal Firefox profile and the "default-release" profile backed up. The "default" one is over 3GB and has over 20k files in it, and my personal one is only 113 MB with 1300 files — and my thumb drive needs all the extra space it can get. (Why would the "default-release" profile be so much larger than my personal one?)

The old laptop runs on Windows and the new one will have the Linux OS. Will that make a difference in using a backed up Firefox profile? I mean, will the data still work in the new OS?

What's disturbing is how many websites you have blocked my access to? We may never know. USAA is one of the most important websites I use. Hell, I've been a member since 1985. But you don't allow me access. I have to use a Microsoft program like Chrome (I also hate) or Edge is what my Dell laptop came with, so you force me to use that when you don't allow me to use USAA.

I'm about ready to switch permanently to Edge. All I need is 1 browser, not headaches. You're not reliable.

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Hello At the moment I is not able to log into an official Spanish WEB-site using Firefox version: 113.0.2 (64-bit) /Windows 11. I have sent the following question to the certificate issuer (accv.es):

I have a certificate issued by you which is verified OK. It works fine with:

https://sede.agenciatributaria.gob.es

https://www.suma.es

but with dgt: https://sede.dgt.gob.es/es/ I get this message when trying to log in to 'mi DGT': XML Parsing Error: no root element found Location: https://sede.dgt.gob.es/es/mi_dgt/index.shtml Line Number 1, Column 1: Can you help find the solution to the problem.? I can not find a DGT-contact to ask for help Best regards Morten Brinch

Accv.es have so far not given me any clues to what I can do.

Anyone having suggestions how to fix the problem ?

best regards Morten Brinch

Screen goes black when some videos play - audio continues, but screen is black. I am sire this is a Firefox problem - I have successfully watched videos using BING browser - same videos go black on Firefox. I have refreshed Firefox, cleared cache, restarted Firefox - cleaned cookies. Turned accelerator off then back on - because nothing changed. Does not do this with all videos, just some - some You Tube videos play, others do not. I have Windows 10 and McAfee Live Safe - all programs are current and up to dated.

Hi,

I have a policies.json file that acts as a white list for me (black listed all urls and then white listed needed urls). I was wondering is it possible to create a second .json file that will act as a black list. I want to give access to a partial admin. user to the policy.json file to be able to edit the file and add websites if needed but I want a another black list running as well to block out specific websites (this one the partial admin. will not have access to).

So to start off the first question would be is firefox only limited to one .json file for policies or can you have multiple .json files (I want to call the second file blacklist.json)? Btw I use Debian and Firefox-esr.

Thanks.

Hello! When I try to log into my Microsoft 365 Outlooks, I get the following message:

'Your browser is a bit unusual...

Try disabling ad blockers and other extensions, enabling javascript, using a different web browser or turning off your VPN.'

I did go in and turn off the ad blocker. I do not have a VPN, and I could not find anything about Javascript on the Preferences page.

Please let me know what to do so I can log into my email.

Thank you! Christine

In a simple HTML file containing an Arabic / Urdu / Persian phrase: "با نشئہ درویشی در ساز و دمادم زن", Firefox in Linux (Ubuntu, to be more precise) uses the default font (DejaVu Sans) for the whole phrase except for one character (UNICODE: 6C1). Font used for this character is Noto Sans Arabic UI. So the text looks broken due to different fonts.

Please have a look at the attached screenshots for better understanding.

I've tried to search but could not find how exactly Firefox resolves preferences in Font Settings and CSS "font-family" preference to local fonts in Linux. Does this have to do something with "fontconfig"?

How can I make Firefox use only the default font for the whole phrase?

Hi,

All of a sudden I need to click the bookmark this page star twice to get the drop down menu. I've cleared the cache, stopped hardware acceleration, & disabled addons in trouble shoot mode. No joy.

Any help appreciated. Thanks.

Hello, I have a situation I cannot explain. Firefox has created over 47,000 bookmarks to the same location. This happens in multiple folders. One is just google. Another is a website I use for work. I delete them and they keep coming back.

I have sync turned off.

Any other ideas?

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

tried searching for this but unfortunately i didn't find any relevant posts
