I am writing a WebExtension to communicate with a server using XMLHttpRequest.

I load this WebExtension temporarily by about:debugging. It works well if I do not login into my Firefox account. It can get data from the server.

But after logining into my account, it returns "xmlhttp.status: 0" immediately when I trying to do the same thing.

I removed all other add-ons and WebExtensions, But still I have this problem.

Any suggestions will be appreciated.

Is there a way to change the location of the default storage directory? I'm talking about ~/.mozilla/firefox/tjdaag57.default-release/storage/default which gradually fills with files from all the websites I've visited. That directory slowly increases in size and I don't want that, so I'm looking for a way to change the location where these files go.

Greetings. I have scoured the web and read all the community posts on this robot head, under remote control, and orange stripes in the address bar problem that so many people seem to be having. There are a few answers, but almost all of them use very technical terms that are way above my head and not defined. None of them provide a sequence of steps to fix the problem that a browser novice might be able to follow. Surely there must be a way to fix this or to explain to frustrated users why it is there and not removable. None of my other Firefox browsers have this on other machines.

Is there a series of steps to solve the problem? That would be so helpful especially without undefined terms. Thanks so much. This type of answer will help so many frustrated users (me included of course) :)

I browsed a clothing website for less than 5 minutes by typing in the address and not using any links. Shortly after I receive an email asking if I was still interested in what I was looking at. Does Firefox share my email address with websites I'm visiting? I believe the email is coming from SafeOpt, not the website I visited. I do have "do not track" options selected in Firefox.

Before I close the Firefox browser i go to Settings>Clear Data> Cookies & Site Data>Cached Web Content. I clear all and the Cached Web Content is lowered to 45kb. History is deleted. There is nothing in Manage Data or Manage Exceptions. The computer is turned off. A day later the computer is turned on and Cached Web Content is 2Mb.

Windows Defender anti-virus malware scan and full scan have been run. The computer is up to date, Win 10 Home, version 21H1, OS build 19043.1237.

Any idea what is causing Cached Web Content to grow from 45kb to 2 Mb when the computer is turned off?

Firefox will not update, but continuaaly load unstoppable popups suggesting I download and install a new copy. This is "Firefox for Acer". One other question about this was answered "I assume that you can ask this at the Acer support forum as they should know this best." wgich means, I suppose, that the responder doesn't knowm but likes answering questions.

Does anyone know? Is this why Firefox fails to update? Will re-installing eliminate the problem? Is there any way to stop the popups?

I set up a Jitsi Meet server, and when starting a call, it asks for permission to use my Blu Snowball microphone.

I click yes, and it says microphone permission allowed, but Jitsi never gets access to it.

I believe this is an issue related to Firefox because I've tried multiple other browsers and it seems to just be Firefox that this issue happens with. Every other browser lets Jitsi Meet use my microphone just fine.

Please let me know if you have a solution to this or have also experienced it!

Thank you, Cross

I just fired up a computer I have not used in like 6 months.

I tried to login to my CURRENT Firefox account which I use with 3 devices.

I go through the email + password + verification process but when I finally enter the verification code (sent to the RIGHT email address) Firefox says "wrong password" and shows an OLD email I used to use.

I changed this email twice at least in the past 1+ years so I am not sure what's happening.

Hi.

Two things keep happening in the Firefox preferences menu on my MacBook Pro, Every couple of days or so.

  1. The default setting for Home > Homepage and new windows reverts to Firefox home (default) even though I have set the URL to which i want FF to go when I launch it.
  1. Likewise, I set the Default search engine to Google, but it (along with the above) defaults the Browser default (Yahoo!). I have to reset it + go to the Search Shortcuts list and remove the Browser default.

This started happening suddenly a few months ago. Finally, I got irritated enough to ask for help here.

Thanks for your help.
