I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

Hello,

My name is Grey, and I'm experiencing an issue using Firefox as a browser to open my Outlook mail. For the past three days I have not been able to open any emails as a network error screen appears. Using other devices and other browsers like Edge, the emails open fine, so it is not actually a network issue. This problem only occurs using Firefox, and specifically with Outlook emails. Everything else functions fine and I have not made any changes, besides the regular Firefox update. My computer is also up to date.

What can I do about this issue? I appreciate the advice,

Yesterday I was unable to sign into The Guardian website (https://profile.theguardian.com/signin?INTCMP=DOTCOM_NEWHEADER_SIGNIN&ABCMP=ab-sign-in&componentEventParams=componentType%3Didentityauthentication%26componentId%3Dguardian_signin_header and https://profile.theguardian.com/signin? )

The problem is that after I click "Sign In", that little circling line becomes the Energizer Bunny, circling away and circling away, but not logging me in.

I have no problem logging in using those login pages on Edge, so confident of username/password combo

I have (repeatedly) turned off tracking protection, Adblock Plus & Privacy Badger for the site, cleared history (cookies and cache, as well as all), followed the complete set of instructions at https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords, and refreshed Firefox. Still the same problem.

HELP - I don't want to be forced to use Edge :)

How do I get Firefox browser to stop from loading automatically upon booting up or restarting?? This has been happening since the last browser update. I checked the Firefox controls but could not find a button to toggle this off. Please advise. Thank you.

Hello,

I am trying to force two or three websites to detect my timezone as UTC, even though my local system time is not UTC. I figured out how to do this with ALL sites by setting privacy.fingerprintingProtection to "true" and entering "+JSDateTimeUTC" in privacy.fingerprintingProtection.overrides in about:config.

Now according to docs, privacy.fingerprintingProtection.granularOverrides "can be used to add or remove features on a domain granular level if privacy.fingerprintingProtection is enabled," but I can't figure out how to get it working.

Any input is appreciated.

Hi, I have been using firefox for many years and never showed me an UAC popup requiring permissions to update firefox as soon as i clicked the firefox icon in the taskbar. Today suddenly required it. I am administrator in windows 10, and have automatic updates enabled as always. I am using 125.0.3 (64-bit) version. This could be a bug or a virus? i am worried that could have given permission to a virus to install something else when i pressed the firefox icon.

What's the best way to set up Startpage private search in Firefox? Should I manually change the settings or install the extension? Also, it seems like Firefox could improve the process for us.

When on the Princess Cruise web site looking at various cruise options, the Firefox browser will not let me open the list of excursions for the ports on the cruise that we were looking to book, but I can see them when using Google Chrome. Why won't Foxfire allow me to view the excursions - it use to allow me to see them.

Firefox - latest version, in Win 11 updated version, on my home server, will not load google.com pages, but intermittently works OK - frustratng. Other browsers, eg. Edge and Chrome access sites as normal on my laptop on my home network. My laptop using Firefox will load google.com pages when on another network. Is it my server, or Google, or Firefox doing this ?? Please provide any advice on solving this problem.

Dear Sir:

I have used Firefox as my default browser. However, when ever I click a link in my outlook email...it opens the page in MS edge. How can fix the issue and ensure the page opens only in Firefox.

Hello,

I recently deleted pwnedpasswords.com from my cookies, as well as blocked this website; however, it keeps reappearing in my list of cookies.

I've never even visited this site (that I'm aware of), and it's a bit concerning to me.

In spite of clearing ALL my cookies (and blocking this website), it keeps appearing in my list!

Please advise :)

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

I can’t seem to open any Word files in Firefox. Doesn’t matter if it’s a new file or an old one, it just won’t open. What’s weird is that it takes me to a OneDrive page saying the file doesn’t exist or isn’t available. But when I switch to Google Chrome, everything works fine.

I use the Kindle Cloud Reader (https://read.amazon.com/kindle-library) to access and read ebooks in my Amazon Kindle library. Since the latest Firefox update something is preventing my ebooks from opening correctly. The ebooks open, but only a single page appears and none of the navigation controls load.

Amazon support suggested trying a different browser. I loaded the Edge browser and had no problems opening my ebooks. I prefer to use the Firefox browser so I hope you can fix this issue.

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My Firefox browser recently updated to 115.11.0esr (64-bit), and now embedded videos won't play, I can initially see a picture, but instead of starting to play, the screen turns dark green and I can only hear the sound. This happened once before recently, but then it seemed to fix itself after a week or two. How can this be fixed?
