I've been trying to access some resources hosted locally with a web extension for testing, but I've been encountering CORS errors. I've added localhost to the permissions field of the extension's manifest.json, but I still encounter the CORS errors. I saw that bugs 1220810 and 1488740 addressed similar bugs in FF84, but Firefox still won't let me send the requests. If it helps at all, I've been trying to access the resources hosted on localhost from an https context, but I was under the impression that those bugs should have fixed that issue?

Ideally I wouldn't need to implement having the server respond with the CORS headers since it only seems to be a problem with Firefox in a local context. Accessing the local resources through Chrome works, and accessing the resources through the internet with the domain name in the permissions field of a production build of the extension's manifest.json works in Firefox. Is there a way to make Firefox disregard CORS enforcement for localhost for temporary extensions?

When sending email messages to my HP officejet pro 8720 I find that it prints Firefo" instead of Firefox and it omits the letter y so words like flyer are fler. Other places on screen where font is another size the letter y does print.

Mac OS X El Capitan version 10.11.6

Hello everyone,

looking for some help with Firefox after recently making the switch from Chrome. Firefox (on Mac) simply doesnt save my tabs and does not reopen them after closing Firefox or restarting. I have checked all the help sites, settings and whatelse but cant find a solution for this.

I just started using Firefox recently. I can't get my search engine to stick. Every time i change it it changes back to Google. Every time I delete Google it shows back up . It's like a bad infection. How can I change my search engine and not have it revert back to default? I have performed all of the recommended procedures with no success. And I have no add-ons installed.

I work with a MacBookPro, system macOSCatalina 10.15.7 and the current Firefox browser 84.0.2.

I am currently having problems downloading documents.

Since yesterday I can no longer call up and download the online edition of a newspaper that I have subscribed to.

This is still possible without any problems using the Safari browser.

I updated the Firefox browser on January 7th, 2021 (to 84.0.2).

I haven't changed anything to the Firefox settings since January 7th, 2021.

What should I do?

Hi to everyone,

I de-Synced my account and unfortunately click on the dialog box that asked something like Do you want to delete your bookmarks and settings locally stored on your dvices ? So i lost my bookmarks.

My Question is : Does Firefox keep a backup of my bookmarks ? Because I want to restore them on my my browser

I've been using new fonts to customize my firefox, but I found that the fonts I installed won't show up in the dropdown menu in preferences, I have to create a new profile to let the new ones do.

I don't want to change my profiles from time to time, so I turned to userContent.css, but I found it either cannot cover enough contents, or cover too much, causing some icons to break.

So the only way to change font for me is to find a way to let the newly installed fonts to show up properly in my current profile, but no matter I restart my browser or my computer they don't. The fonts I have must be read at the time I create a profile, and I guess the list is stored in either somewhere in my profile or under the firefox program folder.

I made every effort to search for it but failed, all I know now is it's not in any text file under profile folder, I wonder if anyone can help me with locating the list of fonts. My firefox version is 84.0.2 on MacOS Catalina 10.15.7.

I have configured FF to block all cookies under "Browser Privacy" the custom setting allows "Choose which trackers and scripts to block. and I selected "all cookies". Knowing that all cookies will be blocked I logged into office 365 and allowed manually cookies through "view page info" I then selected "set cookies" to allow expecting full access to office 365 mail, but this did not occur. What happened is I logged into office 365 and could see the icons and my login name but could not read the mail.

Office 365 gave the message "we couldn't sign you in please try again" yet I could see my log in name and the office 365 icons for mail, calendar etc.. just not the actual data. If I allow cookies in Browser privacy (which i take it allows cookies always) it woks.

I bring this up because it seems like something is missing in cookies that is not represented in FF.What is the difference between browser privacy cookies and allowing it through view page permissions? Can anyone offer an explanation?

On 1/5/21 at about 1200 PST, Other Bookmarks popped up in my Toolbar. I am trying to remove it but have had no success. I deleted the one website that was in Other Bookmarks but it is still in my Toolbar. How do I remove, Other Bookmarks from my Toolbar?

Question: Is there a way to save the personalized session screen under a reference name?

I have created a screen with some 10 fixed tabs that i use each day in a fixed order. It enables me to quickly swap from 1 tab to another.

In preferences I opted for restore sessions, and it works, but sometimes (e.g. after OSX upgrade) i loose the session set-up and have to re-organize all the tabs again.

Thks in advance for helping me out. EvK

No I have no main password on the firefox yes all the credential options are properly setted that this firefox have to import the other passwords from the device.

Anybody there able to give simple instructions no geek expressions step by step guide AND RELATED to my problem not other things?

Thank you

As captured in the long thread "What's the difference between ALLOW and ALLOW for a SESSION?”, with a lot of handholding from jscher2000, I managed to set custom choices for privacy and security the way I wanted on my mac computer (blocking all cookies in all windows, with exceptions saved for ALLOW, ALLOW for SESSION and some for BLOCK). To accomplish this, required enabling deletion of cookies when Firefox closes.

My assumption based on information I got in the above mentioned thread, was that even when deletion of cookies is checked for when Firefox is closed, cookies for websites identified as exceptions with ALLOWED, are not deleted.

However, this is not what happens. A specific example is tripcheck.com, which stores custom itineraries for cameras in cookies. I setup quite a few of these custom itineraries and saved them and they were OK until I closed Firefox, when they were deleted, as the cookie was deleted. This website is setup as ALLOW in the Exceptions list.

As explained in the above mentioned thread:

"(2) Scenario Two

[X] Delete cookies and site data when Firefox is closed (checked)

Firefox shortens cookie expiration to session only unless the site has an ALLOW permission in the exceptions list. “.

I am more confused than ever, the settings do not appear to be working the way they are meant to work, not only for session cookies but also for what should be "permanent".

Am I doing something incorrectly or am I misunderstanding how setting should work?

If cookies of websites setup for ALLOW are deleted when Firefox is closed, the setting is defeating what I am trying to accomplish: saving cookies for websites that I use and save data in cookies (such as recognizing the computer, what’s needed for 2 step authentication, etc.).

Thanks.

Every once in a while the Firefox browser will close down (I'm assuming for an autoupdate) when it does it clears my chosen search engine as well as the information of recently closed tabs and windows. This means that when it restarts I have to search through my history for the sites and pages that I had open before it closed down. Why is this happening? and is there a way I can stop it?

I want to load a website. It is listed in the URL with the Red Anti stripe through the Padlock Icon. I try to Google Allow Unsecure Site Firefox. I also try to rearrange my search words, over and over. All of the "solutions" suggested in Firefox support blog require changing 9 security settings in 3 different sections of the preferences for the Browser. That is not that difficult. Note, I do not see any "solutions" suggested since 2018 or earlier. Caveat. I have to go back into the settings and change them back and restart Firefox for security to move on to UnSafe mainstream sites.

Is there not an "Allow Once" button, or Site Exceptions option? If so, how may steps is it to get there? How many steps to return to save browsing? This choke occurs with low skilled, low tech Pages, not sites.

I am attempting to view http://www.fortvan.org/pages/pearson-air-museum I can find no way of allowing this site/video to load without redesigning the browser, running 40 miles, cooking a cake, and painting the neighbors barn?

Should I just got to Chrome, who I hate, or Brave and get free crypto tokens?

I use the firefox browser with my macos big sur. I disabled the spell check, but I keep on seeing red underlines when I type in the search bar. I thought when spell check is disabled, this should not be possible. (excuse my English). How can I get rid of the red underlines?

Hello someone, anyone. I'm trying to import Bookmarks from a Time Machine backup. I've looked everywhere and tried everything I know and I'm not new to computers, although I have not had to import bookmarks in a long time. I'm on an Imac Catalina, backup is on High Sierra, current OS is 10.15.7 Catalina, lost my bookmarks when I upgraded to Catalina because I had to do a clean install. Any help would be greatly appreciate and I may consider putting you in my Will. Robert

This question has been around for years... Isn't anyone else annoyed by having to clean up UNPINNED Top Sites one at a time? I posted over four months ago about trying to find out where Top Sites stores those unpinned sites... no one seems to know, except to say they are placed there by Firefox internally. I presume that means it is hidden in the code somewhere. Someone on the development team must know where? Maybe if there was a poll of users about this annoyance?? I wish I was younger to be able to get back into coding... my old brain just isn't up to it... ________________________________________________________________ You can lead a horse to water, but you can't make 'em think...
