Firefox Prevents Local Machine File Access But Firefox Dev Ed Allows It . . .

Local Machine: Dell Inspiron i5-7200 / 16 GB RAM / Local Op Sys: Ubuntu 20.04LTS Firefox version: 99.0 FFDE version: 100.0b5 Node.js version 14.18.1 npm version 6.14.… (read more)

Local Machine: Dell Inspiron i5-7200 / 16 GB RAM / Local Op Sys: Ubuntu 20.04LTS

Firefox version: 99.0 FFDE version: 100.0b5

Node.js version 14.18.1 npm version 6.14.15


I had a Node.js web app running on my local machine all usual browsers like Firefox, Firefox Dev Ed (FFDE), Chromium, Edge, Opera, etc till recently.

Recently it shows an error when run on Firefox (also on Chromium, Opera and Edge) although continuing to run okay on FFDE.

Firefox Error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/sandbar/Desktop/nodeapp-local/undefined. (Reason: CORS request not http).

Edge Error: Access to XMLHttpRequest at 'file:///home/sandbar/Desktop/nodeapp-local/undefined' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, edge, https, chrome-untrusted.


Naturally, I need to test the web app on my local machine using several browsers before I should upload it to a server and trial it there.

So how do I configure the browser and/or app to allow access to local machine files ?

Whenever I click on a web search link that goes to Facebook, my Firefox browser back button is cleared. This makes it impossible to go back to my original search easily.

When I remember and notice, I open link in new tab to retain my history.
This started happening several months ago and can be frustrating when doing deep searches.
 I hope there is a security setting I am missing that is allowing Facebook access to my browsing history!
Thanks for your help!

I want to be able to close Firefox and have all cookies and site data removed - but I want to keep my history.

Checking the box to do just this in 'Privacy & Security' will delete cookies when I close Firefox - but all the site data remains. Under 'History' I have 'use custom settings' enabled, as well as 'remember browsing and download history'. I've tried various permutations of this, but can't get it to do what Firefox says it will.

Being able to do this is one of the main reason I want to use Firefox, but it doesn't seem to work. I have to manually delete both cookies and site data.

Any suggestions to try to delete cookies and site data when Firefox closes, but remember history?

The reason I'm asking is that the minimum TLS 1.2 restriction (no override in the error page) was previously stated as being part of the 102 release. Here is my original question

Release Schedule: https://wiki.mozilla.org/Release_Management/Calendar

Just would like to know for sure, if possible, thanks!

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

Hi.

I need to print out my saved passwords. I have no cellphone to access, just my laptop and printer. I only use Firefox and no other browser. If my laptop gets hacked or breaks down, then I need to use someone else's computer to access my passwords in an emergency, and can't access my passwords to do so...so printing them out periodically is the smartest thing I can think of.

Help, anyone? This is pretty important to me. Thank you!

Hi there. I'm in the process of switching from Chrome and I want to import my passwords.

I first tried the 'import from Chrome' option - it says it's successful, but nothing has actually been added. Same result after several attempts.

I then tried the csv route. I found out I had to change the config settings, so I did just that, but the 'import CSV' option still isn't showing even after a reset.

So now I'm at a dead end. Any bright ideas please? TIA!

FYI I'm using Firefox 99.0.1

My macbook is a 2019 16", running Monterey 12.3.1, and has the touch ID sensor on the top right of the keyboard. I love having it for all my log-ins, but can only make it work in Safari. When I look online I'm told to go into settings> privacy > and then just choose the toggle to turn it on. My version of Firefox (which says it's up to date) does not have that option in the Privacy and Security section of settings. Any thoughts? I'd rather use Firefox than Safari, but that is a HUGE feature to me. Thanks!

I'm trying to make it so I can require a password to open firefox settings menu. I'm not talking about primary/master password settings for sites, I mean clicking settings from the upper right three bar requires a password.

I'm setting up a laptop for my daughter, and I don't want her to be able to fiddle with them, and all google will show is the master PW thing that has nothing to do with what I'm trying to do

Hello,

The pop-up blocker exceptions are not working for some sites which I, of course, use a lot. The sites are listed in the exceptions, but Firefox stubbornly continues to block them. I sincerly consider walking away from Firefox (notwithstanding I love it and being a long term user), because it happens with sites I frequently use on a daily base.

I've looked around but none of the solutions work for me as those articles are rather old.

My version of Firefox: 99.0.1 (64bit) running under Windows 10 Pro

Hoping to find a solution here.

I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

Hi, I tried to download a script but Firefox warned me it had a virus / malware. So I immediately put it in trash, emptied trash, restarted my Macbook and used Bitdefender to scan my Mac. Fortunately it detected no viruses. So I think I'm good (Hopefully!)

But, every time I open Firefox now, a little window appears at the top showing my last download and telling me it had a virus or malware - I'm posting a screenshot of this. I removed it from my history, and cleared the preview panel, but it still pops up. To be clear, this only happens when I completely close Firefox and reopen it, not when I just open new windows or tabs.

How can I get it to stop popping up with this message? Also - one other oddity, each time I open Firefox, it says the time this script was downloaded matches the time I open Firefox (as opposed to when I actually downloaded the pdf - about an hour ago)
