Firefox Support Forum

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 ?

I've been through the usual listed issues, refresh, disable add ons (only one), disabled AV, clear all history, passwords, etc. Checked that the latest update is installed. Have done malware and virus scans with no ill reports. This can't be normal. What else can I try to resolve it b efore moving on?

I just updated last night to version 98.0 of Firefox, and have noticed that when I click on manage bookmarks that the boomarks now open at the bottom of the various bookmarks folders by default instead of opening at the top like they used to. What happened here? I am including a picture to show where the manage bookmarks section is going by default now instead of where it normally does. Can anyone help fix this?

Lately I am getting a lot of spam emails. Is there a way to get rid of them permanently? Are there any free add=ons to install that will block them out? Please reply.

Since Firefox 98, whenever a file is downloaded or a page is captured (using add-on Page Saver WE) a display/pop-up appears in the top right-hand corner of the screen (or possibly under the 'Display Download Progress 'button'). Previously, this prompt/display/pop-up would disappear after a few seconds. Now it stays there until there is a mouse click anywhere on the screen (including outside the Firefox window). This is presumably a bug and it is also extremely irritating. Please change this back to the way it used to be (disappearing after a few seconds) or provide an option to specify how long the prompt/display/pop-up should be visible - like the 'new mail' prompt from Thunderbird. Many thanks.

The option "always open similar files" is not shown in the downloaded file context menu. This occurs on 2 machines running Windows 7 64 bit. A third machine also running Windows 7 64 bit shows it correctly. All three machines have Firefox 98.0.1 installed.

Please advise how to resolve this.

I got into Firefox and Poof! All of the Tabs at the top of the screen were gone. The "Recently Closed Tabs" offering in History is not highlighted. I've used that before to get them back. Now, how do I get them back? I was saving them for reading later. I'd like ME to be in charge of Tabs. Seems like I'm not. All tips welcome! Thank you. CD Happel

Hi,

I was working on my work on a Google Doc, and when I tried changing the font, Firefox immediately crashed after clicking the font box. When I restarted, Japanese characters turned into boxes with codes in it. I have the Japanese language installed on my system and it works fine on my system. I also have the Japanese language installed on my browser. Other characters appear as the same thing, but I don't know for sure what they are other than Chinese and Korean. My cursor also changed to what looks like a hand pointing at something whenever I hover over something, however I am unable to provide a clear screenshot of that so I can only provide pictures of the messed up Japanese characters.

How would I fix this?

System OS: Ubuntu 21.10 Firefox Version: 99.0

I see the thread was closed without a solutuion. The CIRCUMVENTION being 'fiddling' about with 'config'. Just to re-state.... Since Firefox 98, PDF files that are OPENED within Firefox are also automatically (and INCORRECTLY) downloaded. If the PDF file is subsequently requested to be downloaded (using the 'button' within the PDF display/window), Firefox will either: Prompt stating that the file already exists; or (if the user picks his/her own filename) a 2nd copy of the file will be downloaded. Sorry to be direct but THIS IS A BUG THAT NEEDS FIXING.

Hi, I received notification of a breach, including password compromise. I've checked and don't see the app. What is next? What to check? What to do? (if the auto reply is 'don't sweat it', what does that indicate about the service?) Thanks!

I recently installed a theme that I really like, but the search bar by default is a blinding white color and it contrasts heavily with the dark blue colors in the theme I picked.

Is there a way for me to edit the background color and text color of the search bar to be a different color? I've tried looking at different solutions and most of them make reference to userchrome or something else I have absolutely no idea how to work. Can someone explain to me, in the most simple and hard to get wrong terms as humanly possible, how to change the background and text color in the search bar? Is this something I edit the theme itself for? How do I do that?

Thanks in advance. Attached image shows the part of the browser I'm talking about if it somehow wasn't clear enough. I'd like to turn the white color into, say, dark blue or gray, and change the text color to a light blue or white.

Help me fix Firefox so it reaches the English version of www.ebay.com. I uninstalled Firefox and reinstalled it and this still happens. Ebay is the only site at which this happens,'

when I input www,ebay.com in any other browser, I am brought to the correct version of eBay.

PC goes to sleep and app running is Firefox with webpage for Facebook the focus when it is awakened my system crashes. I have spoken to Microsoft and they have checked out my PC but cannot say that what they have done will resolve the issue as the machine wakes perfectly when the web page in focus is anything else. Do not know if it is a firefox or facebook problem but a problem it certainly is. One of you or both in combination causes windows to crash in these circumstances. As Microsoft has done its thing with reguard to windows and my PC and because it only seems to happen with a combination of firefox and facebook they don't think they have a problem but it is with their development team for further investigation. You now need to investigate. I have the report problems to firefox box checked so if you need anything further please get in touch.

I think someone tried to hack my account. I was stupid enough to order a product online and give all my info. Firefox locked me out. I can't log in. I changed my password but can't let Firefox know I did. I REALLY need to get back in to Firefox! I trust it and don't trust the other browsers!
