Firefox keeps displaying '400 Bad Request Request Header Or Cookie Too Large' when trying to read articles on www.bloomberg.com.

It only happens when using this site and only on Firefox and not on Safari or Chrome.

How to fix this and be able to use Firefox as default browser for this site?

regards, Arjen

A few days ago I found that Captcha was not working in Firefox on a Mac. I click on the relevant squares but get a new screen to work on. It just goes on and on and no matter how many screens I complete it won't let me through. It works fine on other browsers.

I hate Captcha and can't understand why webmasters can't use a better system to check that a viewer is a real person.

Is anyone else having this problem?

Hello, I use Firefox on my Mac, and I'm a seller on Etsy. For several days now, I have not been able to get to any page on the Etsy site (my shop, Etsy home page, Etsy help, other shops...). I can get there on my iPhone (Safari) and by using Chrome, which I would rather not use.

I've tried shutting down my Mac, and I've tried quitting and re-starting Firefox.

This is not the first time I've had this issue, but this is the longest it has lasted. I checked with a friend who is also an Etsy seller, and she's experiencing the same problems. It occurs to me that the intersection between Etsy sellers and Firefox users might well be a large group.

The details: MacBook Pro 2015, MacOS Catalina 10.15.7; Firefox 83.0. Today is 2 Dec 2020.

If this is about clearing the cache, I'd appreciate some info about how to do it, as well as what might else could be impacted.

Thanks for any help on this!

How can I sign up for Mozilla (firefox) forum?

I have an account, but won't recognize my credentials. They ARE correct.

I try to set up a new account and the security question "how many letters in Mozilla" doesn't work. The answer is 7, but says it's wrong. WFT?

Bluetooth headsets continuously toggling call mode when using microphone

In recent weeks, calls with audio have become buggy in Firefox. Whenever I engage in a call that accesses the microphone while I have a bluetooth headset connected, the headset starts continuously toggling call mode on and off for an extended duration. This can be anywhere from 10 seconds/3ish toggles to never-ending (meaning I got tired of waiting after about 3 minutes/55ish toggles).

Today I finally decided to debug further. Here are my findings:

  • Problem only exists in Firefox. I tested with Safari, Chromium, Slack and Discord, with no trouble presenting itself in any of them
  • Problem relates to all bluetooth headsets. I have tested with Sennheiser Momentum 2 Wireless and Steelseries Arctis Pro Wireless, with both exhibiting the problem in Bluetooth mode. If I have no bluetooth headsets connected, the problem does not present itself. There is also no problem if I connect the Arctis using the wireless base station (which in turn is connected to the laptop by USB) instead of bluetooth. Using the base station, call and non-call are exposed to my mac as different/simultaneous channels — this may have something to do with it.
  • Problem persists with hardware acceleration toggled off
  • Problem persists in safe mode
  • Problem persists in private mode
  • Problem persists both on Whereby.com and Discord.com. On Whereby, it also interferes with the camera. This leads me to believe it might have something to do with WebRTC, as I think both websites use it.
  • Problem persists after reinstalling Firefox
  • On a possibly related note: if I end the voice chat session after it has stabilised, call mode toggles off slowly and always sends a "start playing media" signal to my Mac, even if it didn't pause anything when toggling call mode on.

In sum, this leads me to believe there is some sort of bug in Firefox causing this, but the lack of other topics on here with the same problem makes me skeptical. I am open to any suggestions with regards to further testing I can do. This is obviously very annoying, and I would like to have bluetooth calls working again.

Recently, I have been blocked from visiting certain websites by Firefox, which are perfectly fine websites. I have to close out of Firefox and use Safari to connect to these websites. One of the websites is my City of San Bruno website: https://www.onlinebiller.com/sanbruno/index.html.

This is just one of several websites in which I'm told the website there is a potential security issue. Did Not Connect: Potential Security Issue: I copy and pasted the warning below: "Firefox detected a potential security threat and did not continue to www.onlinebiller.com because this website requires a secure connection. What can you do about it? www.onlinebiller.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem."

I contacted the City of San Bruno and was told it's a browser problem. As I mentioned above I can connect to these sites through Safari with no problem.

Thank You for any explanation/assistance on how to connect to these websites using Firefox.

Hello,

I'm posting because I found nothing on the internet about this.

When I want to drag and drop a file from Firefox (for example : an image) to my desktop, the file always get placed somewhere decided by Firefox instead of the place I wanted.

Example : I want to drag and drop an image from Firefox on the bottom left of my screen, and it gets placed on the top right.

This is really annoying because Firefox always decide a different place to put the file, and I always lose time looking for the file on my desktop.

This is the only application that I use that does this.

Is this possible to fix ?

Thank you for helping !

I've been having this issue ever since the latest release of firefox.

Essentially it will be fine for a while and then all of a sudden firefox is unable to retrieve any headers from the fetch response. If I refresh firefox this fixes the issue, but only for a small amount of time. The same bug doesn't happen on chrome and I haven't had it happen to me yet on firefox developer edition. It happens if I use this browser on private browsing with no plugins as well.

Note that we do use a fetch wrapper but it essentially returns the entire response object in the screenshots below.

Also note that it doesn't seem to happen anywhere but localhost. Is there anything I can do here?

Hey y'all,

First, thanks for your attention. This has been driving me nuts over the last few weeks and if I can fix it I'd be very happy.

I switched to Firefox a few months ago and immediately set up the password manager and a bunch of bookmarks. Unfortunately, the next time I shut down my computer and restarted, Firefox said this browser was a new installation and had totally reset, with nothing saved.

This happened again a second time, so I set up a Firefox Account so I could have the settings saved to a profile rather than an installation.

Every time I restart the same thing happens: Firefox has a 'new installation' and none of my settings. The first time I logged in to my Firefox account to sync it, it worked. But I've just installed Catalina, previously using Mojave, and on that restart it happened again, but the Firefox account sync isn't doing anything. Now, every time I open up the browser, even if I haven't restarted the computer, it brings me to the same 'new installation' screen. When I log in to my Firefox account as prompted, none of my previous information syncs. Nothing happens at all after I get the "This Firefox is connected" screen.

I know the sync is at least somewhat connected because I can sync tabs from my phone to my computer.

Any ideas? I can re-do all of my passwords and bookmarks, but I don't want to bother if it isn't getting saved anywhere, or if I can't stop this factory reset whenever my computer shuts off.

I'm on a Macbook running Catalina 10.15 if that matters. Thanks!

Current preference settings are increased font size to 14pt and zoom 110%. Since I set those preferences some websites, mainly ones with form fields, come up as a boxed question mark. Also when I do an internet search is comes out crazy alien like text / weird code. See attached screen shot of a basic search for 'books'. I prefer using Firefox over Safari and would love to remedy this.

Using current version 83 on Mac OS 10.15.7.

Whenever I have to go to a videoconference hosted through the browser (like GoogleMeet or Theranest), Firefox asks me to choose a camera, but it doesn't allow me to choose the built-in FaceTime camera on my iMac. The only option it offers is EpocCam, which I have installed on my phone but never use. (I've attached a screenshot so you can see that I can't choose any other camera – it just doesn't give me the option!) I must have selected EpocCam once several months ago, but I cannot figure out how to get rid of it as an option on Firefox and I can't choose the built-in camera. I've searched for hours to find a solution but can't figure out how to deal with this. I don't have a similar problem on Safari, which is the only other browser I have installed at this point; and I don't want to migrate all my stuff to a new browser just because of this presumably easy-to-solve problem. Help!

Hi- i'm a little confused about the "collections" feature on my pixel. is it supposed to carry over onto my computer? I'd love to access my collections on my desktop. I also recently upgraded my phone- my collections haven't transferred over to my new phone and that's also frustrating. I might just be an idiot but i can't seem to find any documentation on whether collections syncs between desktop and mobile; an indication that this is generally thought to be so obvious it needs no documentation.

Firefox had been telling me I needed to do an update for a couple of weeks. So like a fool, today of all days, I said yes. But I did look at what the update was going to do to make my final decision. It looked good so I said OK.

What it actually did was download the complete app and ask if I wanted to keep the old version as well. So I kept the older version (which had been up to date to this point) and opened the new one. It appeared to be totally "plain vanilla" with none of my bookmarks or windows, etc. I looked for my Bookmarks and all it had was some of my bookmarks from the Bookmarks Bar, none of my tons of years of important and properly organized bookmark folders.

I immediately quit, rebooted my computer, and went back to my older app - remember the one I did say to keep - and I got exactly the same behavior from it. I then completely trashed the "new" version and rebooted my computer again . . . then tried the older version . . . but that time things got worse. I did not even get the old Bookmarks Menu bar.

I then rebooted and went to my backup, brought back the copy from my last backup a month ago, and tried to run it. This time I got a message saying that opening the older version could destroy all my settings . . . but I did not care as I would rather go back a month ago than be where I am now! However, it would not allow me to open the older version because of the possibility of destroying . . . nothing!

HOW do I at least get back to my older version that would have probably 90% of my older Bookmarks/Folders and settings? I have that older copy and a full backup of my HD . . . but I do not know what, other than the Foxfire Application I need to look for and replace on my system. I assume there are some files stored in System folders that I need to replace, but I could not find them as I can't find anything in the Library or System directories that are identifiable as Firefox files.

All help appreciated . . . guess there will be no Cyber Monday shopping for me!

Thanks!
