Firefox Support Forum

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS

I'm a Reddit user and until today I used to login just fine. Now I get the error message "Incorrect username or password" when I try to login in Mozilla Firefox (version 119.0.1 (64-bit)). If I use Google Chrome or Microsoft Edge I log in with no problem.

With certain pdf files, when I go to a page using the outline feature on the pdf viewer or refresh the tab on the same page, the zoom will automatically be set to "page fit". It seems to happen with the title page and table of contents pages. Is there any way to prevent this from happening?

About a month ago, I had no issues taking a screenshot of what's displayed or entire page. Now, whenever I take a screenshot, it copies only 3/5's of the page (from the left margin to roughly 3/5ths of the page both displayed or entire). My settings in about:config have not been changed (well, they are changed but at the same settings as when 'Take Screenshot' worked and now only copying 3/5ths of the page).

Hi Firefox We work in a government institution and we use Firefox because it is a unique, fast and safe program. We thank you for your efforts to develop the browser But we encountered a problem with the new update while printing the PDF files. It was showing us the option to print in portrait or landscape format, and when you updated version 14, this option no longer appeared. Where we deleted the new program, installed the older version, and stopped the update We trust you to solve the problem in the next update, and we ask you to give the matter importance

On all windows in Firefox, both normal and private, I get what looks like brushstrokes over the text. Generally they disappear when I move the cursor, but they also appear and disappear without mouse moves. I have the same extensions running on other PC's but don't get this happening, only on this newly-built PC. Using Windows 11 version 22H2, Firefox ESR 115.4.0 64-bit. In the sample the brushstroke shows about 80 % down the page. It disappeared after about 30 seconds, and other appeared later. While writing this, the same kind of thing was happening on this page. Extensions Ecosia and Ghostery.

I used to be able to use the backspace key to go back one URL in a given window. Now, even though I have gone to about:config and changed browser.backspace_action = 0 to 'true', this no longer works, at least not with my new Windows 11 computer. I tried closing and re-opening Mozilla with the new preference, and again with closing, restarting the computer, and then re-opening Mozilla. Please help if you can. Thank you so much.

I have an account with a French language news site lemonde.fr and want to read the website in French. I selected this option, to default to the French language version, when I created the account on the site. However, Firefox redirects to the English version lemonde.fr/en. I do not want this and cannot figure out how to stop this from happening. Please provide specific instructions. Thank you!

I have just upgraded my desktop to Win11 and have an issue now with Firefox.

I have When you open a link, image or media in a new tab, switch to it immediately checked, but when I open a bookmark or click on a link, the new tab opens, but FF does not switch to it immediately.

I've done a search here, but only find questions on how not to switch immediately. ;)

I have "Open previous windows and tabs" checked in the settings, And have been using firefox in that manner for years, Like I would close the browser without thinking, And coming back to what i was working on. But today for some reason, I came back to all my tabs gone, And I openned multiple tabs and closed, And opened the browser again and there were no more tabs. (I know about ctrl+shift+N, But that is not automatic) Please help I really need this feature, As i don't like closing tabs!

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

I've searched for answers. I tried the About:config and changing some settings to false and others to true as suggested (e.g. browser.search.context.loadInBackground), etc., and of course I have the option chosen under settings.

This is a new computer. My old computer would switch to the new tab when I right click it, but this new one won't.

Any latest fixes?

.... when either trying to open them by clicking "open link in new tab" or by manually opening a new tab, then typing something into the browser-line.

This has been an issue for me now for several versions of firefox ever since like 6 Months ago. It is very annoying, especially after having finished typing a rather long website-adress or search phrase, then hitting enter only to get the new tab closed right into my face without any further comments.

Help would be >MUCH< appreciated!

Cheers~

I get black and or white rectangles on web pages as I scroll or move the cursor. Some times they obscure what is on the page, sometimes a ghost of what is underneath shows through, sometimes they are like a layer between page components. I've attached a couple of screenshots to show some of the problems. I've reset Firefox but it made no difference. Any suggestions? Rhanks Tony

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Would really appreciate a solution for the issue because I really like Firefox!

An answer from legit source (longtime moderator or developer) is welcome. I'm sorry if this has been asked before. I couldn't find it and I'd like to make my point.

I didn't like the design of Firefox when they first started this design with so much space wasted for tabs and toolbar. Every time I open Firefox it feels odd with gigantic empty spaces if I come from Chrome/Vivaldi which are thoughtfully compact.

I have 14" laptop and Firefox makes the UX very less intuitive.

As of now, I'm using the workaround for compact mode that was posted in this forum numerous times. It says (not supported) beside compact mode which makes me feel like that this feature is going to be removed completely in the future. That's the tipping point where I will stop using Firefox completely.

So, coming to the question - wait - Subject is the question...

I hate 2 factor authentication. I don't want to use it.

But I was sent to https://support.mozilla.org/en-US/kb/secure-firefox-account-two-step-authentication because I dared try to make (ok alter) a theme.

Authy sent me a unusable non-windows file, so I tried KeePassXC. It has no place to put a secret key...nor does it even mention one in its guide.

I downloaded KeePassXC just for this, not that I wanted to, so how do I fix this draconian policy need? This program gave me a 16 digit code, but nowhere to enter or use it.

Every time I open Netflix in Firefox browser, to watch streaming movies, it won't show them but keeps taking me to a page asking me to log in again or pay for a Netflix account. (attached) I already have a Netflix account and can watch streaming movies with no problems on other browsers, but not using Firefox, which is my Default browser.
