Firefox Support Forum

Since the recent update to 89.0, I've been experiencing longer than normal initial page loads from start up or wake up for my MBP. Safe mode doesn't seem to matter, and it doesn't matter if a browser window is open and a page loaded or if I'm opening a new browser window, that first page load (or reload) takes much longer than it should (up to 10 seconds to load for example, the Google home page). Once I'm past that initial page load, my browser speed is fine. I also checked Safari and Chrome on this MBE, and neither have this issue, which leads me to believe it isn't a security or some other setting on the Mac.

volume and sound will not work since last 2 updates on both windows 7 and windows 10 comuputers after 89 and 89.1. youtube videos and others will not play sound. They did before these horrible updates. what do I need to put in my userchrome to make them work? Any other fixes.

I cannot access to Facebook or Messenger on Firefox, when i open, Firefox said Secure Connection Failed. I got this error for a week,i have used Edge and Facebook still work,pls help me.

Today, whenever I close Firefox and then restart it, it brings up the tabs I had open last time before I closed it instead of my home page. I checked my settings and "Restore previous session" is turned off. How do I make it stop doing this and why isn't turning it off in settings working?

I cannot add a Zoom meeting to an Outlook meeting using my Outlook Web app. The Zoom add-in is installed and the button appears in the Web app. When I click it, I get the message "Zoom is working on your Add a Zoom Meeting request." But it just hangs there.

The Zoom add-in works using my Outlook Desktop client on the Mac and using Outlook Web in Chrome. Firefox seems to be the issue. Any idea what I can try to fix this?

Firefox on a Windows 10 (Build 19042.1052) that

It starts and seems to run without hanging or crashing. I can enter an url, but it doesn't do anything. The Viewport just stays white. Also nothing happens if clicking on a bookmark. Or the settings. I was able to open the about:support page via the menu, but not by entering it into the adress bar.

Here are the things that I already tried to no avail: - updated to the latest version - Incognito mode - Troubleshoot mode - graphics card driver is up to date - reinstallation - Cleaning Firefox - delete firefox profile - clearing the start cache - downgrade to version 88.0.1

It is weird, that the about:support page works when opened from the menu but not when entered into the adress bar, right? This means that content can be displayed, but you cannot navigate to it via the address list. But then why don't bookmarks work either?

By the way: It is not a network Issue. Chrome and Edge work, and also the problem persists across multiple different networks.

Today I tried to log in to my HSBC account from Firefox 89.0.1, which I have been doing from Firefox for several years. The HSBC home page displays as normal, but when I press the Log on button I get the following message

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have rung HSBC, who say there is no problem at their end and I should try another browser, and the website works perfectly on Google Chrome. Why should this have happened, what changes have Mozilla made to the browser to cause this problem?

I already have to use Chrome to access my M&S Money account due to incompatibility between that website and Firefox. Should I change my default browser to avoid future problems?

Here's the problem: when I try to play a Youtube or other video in Firefox, the sound cuts out after 1 second. Then silence.

I have tried everything. I updated drivers. I tried fixing sound in the sound settings. Nothing works.

This seems only to be a problem with the HDMI output, as it seems fine when I use Bluetooth. However, it is only a problem with Firefox, because it works fine in Chrome and Edge.

Some websites have this text box under their articles to write a comment and post it on Facebook (see the screenshot). But for that to happen, first you must login to your Facebook account. The problem is that when I click the button "login to post", nothing happens - as if I didn't click it at all. I suspect the reason for that are the integrated anti-tracking options in Firefox 89. So the question is: how do I get this plugin to work in Firefox 89?

P.S. Until a month ago I was temporarily using Chromium as default browser and there the FB plugin had no issues. Chromium has no anti-tracking options which is why I think this function in Firefox is the reason for the FB plugin not to work.

Hello,

I have Firefox 89 installed on my PC with Linux (Pop_OS!). The new proton interface does not change the bookmarks.

browser.proton.contextmenus.enabled is set on true.

I'm trying to access a web page from share point for work but it keeps throwing me an error code. I can open the page fine in other browsers.

error.aspx?ErrorCorrelationId=f962d49f-8000-c000-3973-9e39aeb1b0d7&ErrorText=Can't load the application on this page. Use the browser Back button to retry. If the problem persists%2C contact the administrator of the site and give them the information in Technical Details.&ErrorDetails=Error%3A Error initializing application.

I talked to the administrator and he said it was a firefox problem.

Why does Firefox seem to suddenly hate www.aa.com. When I try to log into the website I get a "Sorry working on our website - please start over" notice. I have tried deleting browsing history and I turned off the ad blocker. Any other suggestions. It works fine on MS Edge.

Cursor jumps to toolbar address window instead of staying on the Firefox home page search bar. I prefer to use the search bar, without seeing all the urls show up in a list that changes as I type. This change occurred just a few days ago, apparently when Firefox updated. I have selected Google as the preferred search engine. (there are many other unwanted changes, but this one is the most challenging to deal with)

Hello,

I delete a bookmark and after syncronizing it reappears, after I have deleted it a second time, it is gone for good.

How can I prevent that?

Greetings FloMac

FF auto-updated to 89.0.1, now a site won't work, would like to RESTORE deleted/cleared COOKIES (?!?!) for that site to see if it will help cuz deleted the cookie for it made things worse! Doesn't work under Private FF session either!!

Specifics: I am the Webmaster of (we use WIX to create/manage it) 12cdrc.org and it is working fine using Edge, Chrome, Brave, but no longer works correctly (since 89.0.1, I think happened late last night early this morning on my system) update. Most of the page loads, but the Calendar and display tweets sub-windows will not load! It will be obvious to all where they should be displaying but are not!

So, I tried removing 12cdrc.org cookies. Things got worse! Now the Login won't work either, where I was logged in as my user for the site prior to that.

I tried a Private window/session, and the Login function does work, the Calendar does show, but the tweets sub-section/window still does not display/function.

Background: This is not the first website to malfunction using Firefox... Previous version updates broke the rescuemichigan.com website (none of the pull-down menu functions work, but work fine on/with Brave, Chrome, Edge)! Also mewe.com acts up using FF at times, but a clear of the mewe.com related cookies and relogin at mewe via FF clears up the issues of things not wanting to display correctly or fully on mewe using FF - which is why I thought clearing 12cdrc.org cookies would help in this case (but did not, again, made the malfunctioning worse)!

This makes little sense. I even tried doing D/L of full 89.0.1 install, didn't help.

I'd like to try and RESTORE COOKIES (last thing I want to do is clear all data/cookies for FF) for 12cdrc.org from manual offload of all my userid appdata folder/sub-folders to an external drive (or perhaps appdata backup to Norton cloud backup done a few weeks ago)! But I do not know where to look. Was about to go to my external drive and do complete file search of "12cdrc*.*" to see what would return when I thought I could search Mozilla/FF Help on "Restore Cookies" but only very old question for very old version of FF showed up and it said "IF STILL NEED HELP ASK NEW QUESTION" so here I am doing so!!!

Again, all sites (12CDRC.org, MeWe.com, and RescueMichigan.com) ALL WORK 100% error/issues free using Brave, Chrome, Edge, so this is FIREFOX SPECIFIC and all these issues have started under/after recent FF updates and/or gotten worse, not fixed/better, under updates/upgrades!!!!

Appreciate any Help... 1) like I said, where the Cookies are hidden that I might then recover them from previous save 2) other suggestions?!?!?!

Firefox is displaying text in SOME windows so highly pixellated that it is unreadable. Other browsers display the same windows normally. This has been going on for a couple of months now. I really like(d) Firefox befo0re this happened. Since other browsers display correctly, I feel that it is not a hardware problem. Firefox also covers SOME graphics with green.bold text
