When I signed on to my computer this a.m. and clicked on the Firefox icon from my Task Bar (on the bottom of the page) to bring up my homepage, it wouldn't go. I rec'd a msg stating it "couldn't find" a .dll file or something. When I clicked on the icon on my desktop, it started a whole new page - I lost all my "saved" pages and my "favorites" menu was gone! What happened and how can I get my "normal" Firefox page ?

I am on Catalina OSX and when I press the maximize button (Alt + the green button, just so you know I am not making it full screen), or double click the top bar of firefox, it stretches the window all the way down resulting in the dock hiding a portion of it. This is the only app that has this behaviour and I tried looking around in firefox's settings to no avail :(

I can manually resize the window so it won't overlap with the dock but as soon as I quit and come back to it, it resets to the original problematic size.

Please help ! Pretty pretty pleeeease!

Thanks for your time and I hope every one of you is safe in these dire times!

The latest update of Firefox includes an incredibly annoying "feature". Clicking in the address bar brings up a drop-down list of sites: youtube, facebook, reddit, wikipedia, twitter. This is distracting and I don't like Firefox shilling for these other sites. How do I get rid of these?

Good afternoon. The site is not loading https://www.healthline.com/nutrition/hot-dog-calories?slot_pos=article_1&utm_source=Sailthru%20Email&utm_medium=Email&utm_campaign=authoritynutrition&utm_content=2020-07-03&apid=25358168. Throws error 502 Bad Gateway. The site used to load normally. What is the problem.

As of about a week ago I have been unable to connect to https://weather.com using Firefox 78.0.1 64bit on Windows 10 Pro. As far as I have found in my regular browsing this is the only website with this problem; other websites open properly. The problem with https://weather.com occurs no matter how I try to connect - selecting a bookmark that worked in the past or typing directly in the address bar. If I am using an empty blank window what I see is a window that remains blank. The name that I typed in shows in the address bar but there is no padlock icon and no trackers shield. I am attaching a screen shot.

If I open Firefox in a private window I AM able to connect to https://weather.com as I could before in the ordinary window. I am also able to connect to https://weather.com using other browsers.

Any suggestions as to what has happened and how to fix it would be greatly appreciated!

When using the "Checkout with PayPal" button on websites the PayPal popup window appears however it's impossible to progress to the checkout.

When OneTouch is activated, the text 'Securely logging you in...' appears overlayed with the spinning wheel in the popup window. This continues indefinitely.

When this is not activated the window doesn't progress further after entering the email as prompted by the window and pressing Next.

It's possible to login to PayPal in a separate tab however that doesn't influence the popup behaviour.

Looking at the console in the popup there are a few 'Unable to find window by ref window.js:148:14' errors.

In the 'host' window where the popup was called from the console displays the 'Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://www.paypal.com’) does not match the recipient window’s origin (‘https://www.paypal.com’).' error.

I believe this could be a recent issue because I was able to make several payments last month with all settings the same. I have a separate user.js file that I keep my settings in (I can send it over if required). These settings have not been changed since the file has been created.

The following actions have been tried and didn't improve the situation:

- refreshing the current profile

- disabling all addins

- adding paypal.com into exclusions for 'Block pop-up windows' and Enhanced Tracking Protection

- cleaning History and cookies

I then launched Firefox with a separate 'clean' profile and was able to make the payment successfully. Sure enough, importing my user.js file broke PayPal. I went through the settings commenting them out by groups.

The following setting was causing the issue:

user_pref("privacy.firstparty.isolate", true);

Setting it to 'false' made the PayPal popup window work correctly again.

Thought that this would be helpful for anyone experiencing similar issues. Cheers.

Windows 7SP1. With the Firefox 78.0.1 update, search with Amazon.com, You Tube, Facebook, Reddit, Wikipedia and Twitter appear below the address bar when I start to type the url. I only have as default DuckDuckGo and Start Page HTTPS selected in options, and no alternatives.

I saw the one reply to this issue to use the about:config, browser.urlbar.oneOffSearches, change to false. This did not work.

Why has this been done? I don’t want them and I don’t use them. How do I get rid of this?

I get this error when I try to sign into my microsoft account on Firefox: AADSTS50196: The server terminated an operation because it encountered a client request loop. I am using my home computer which is updated to Windows 10

FF 78.0.1 installed. Why is FF search now forcing a drop down list of these undesirable websites: youtube, facebook, reddit, wikipedia, twitter. I never use these websites, I don't want to interact with them, I don't want to be told about them, I don't want to be directed to them. I don't want to be distracted with extraneous 'options' that divert my attention from the task at hand. This overrides my Preference settings. I already turned off or deleted all the alternative search engines "that appear below the address bar and search bar when you start to enter keywords." None of these new website additions are in that list.

Is there a simple way to get rid of this without monkeying around with internal settings? Company and public libary users are locked out of this.

PLEASE!!! Firefox is not doing anyone favors by forcing new features without warning or explanation in mandatory updates. We keep losing basic functions like the ability to see URLs in the address bar -which I do need - and then spend a lot of time trying to figure out why something unwanted like this started happening and whether it can be stopped.

1. I had downloaded previous PDF files using Microsoft Edge. They came up on Firefox with no problems. I was able to highlight PDF text with no problems. 2. Today, I flipped a switch to download a PDF file using Firefox and to always display PDF files in Firefox. All previous Edge PDF files immediately had their icon changed. 3. Now, I can define the PDF text I want to highlight, but there is no action to click on to make the highlighting happen in a color of my choice.

I had IMDB as a custom search engine in One-Click Search Engines but it suddenly disappeared and now I cannot find any way to get it back.

Any help or info will be gratefully received.

Firefox upgraded to 78.0.1 but my extensions are now inaccessible/invisible. They show as enabled in the about:add-ons tab but no longer appear at the top of the main window - so I casn no longer access them.

Ever since ver 78.0.1 64 bit Firefox was installed, the browser is memorizing ID's and passwords. "Logins and passwords" say NONE have been memorized. MOST DISTURBING, Lastpass is signed in and stays signed in even if I shutdown my machine. My settings for this in Lastpass are being ignored!!!! Please help.

In firefox 77 I could choose different search engine for example duckduckgo as default search engine in private mode. In 78.0.1 this setting is missing, no way to search selected text privately or set different search engine for private mode. Only workaround is to go to about:config and enable "browser.search.separatePrivateDefault.ui.enabled". This fixes both problems. Is this still in beta and not officially available or are my settings wrong?

Hi,

I am running Firefox 78.0.1 64-bit on MacOS Catalina 10.15.5.

I get these unwanted advertisements for Google and Amazon whenever I go to type in the address bar (see attached images). How do I disable them? I can't see any option in the "Search" section of Preferences or searching Preferences in general. My search engine of choice is DuckDuckGo, and I do not have an Amazon account. Why does Firefox think have a desire to interact with these companies?

Thanks in advance for your help!
