Hi I am trying to change the default homepage Firefox logo to my own, but i could find no tutorial on how to do that. I only found 7-9 year old posts, that did not work. So my question is: Is it possible to change the default firefox logo on the homepage to my own one, and if it is then how?

I can't sing in to banking accounts with newest version of Firefox. no problem with Microsoft Edge. I keep getting this message.

Hi, I've just spent all day trying to follow all the different suggestions here regarding these issues. Adding all sorts of things to the userChrome CSS but 95% of the suggestions have no effect at all [I'm seriously non-technical, so I have no idea if I'm doing it correctly though...probably not] The only thing that I can change is the Tab Height...nothing else changes regardless of what numbers I put in there. The only way I've been able to make the Bookmarks folders usable at all is to enable Compact mode via about:config. But that actually makes it way too compact now...from one extreme to the other. At least it's usable now...so not the end of the world, but the right click menu still has way too much space between every entry [Compact mode made no difference to that at all]. I don't know how to make a screenshot of those menus :) so I took a couple of pics of the screen...can someone please show me what to add to the CSS file to make these ridiculously big spaces between the menu items way smaller...like they used to be before this Proton came in? I tried tons of things that people said to add to the CSS to fix this menu spacing thing but none of them changed anything. I'll include the CSS file that I have below. Thanks a lot

ps: for some reason the pics always come out sideways here

I wanted to print out an order placed online but could only print part of it.

The order took up about 1.5 pages when displayed in Firefox, but I could only print the upper 2/3 of it. That’s all the Print Preview displayed. It was cut off at the bottom. There was no option to print the missing lower third or a second page.

I can scroll Firefox to display the lower part but Print Preview still shows only the upper part.

I can change FF’s scale to 80% in order to show the whole order on the screen, but Print Preview still only shows the upper part.

I can scale Print Preview to 70%, but then it’s difficult to read.

I don’t recall having this problem with earlier versions of Firefox.

How can I print my order on 2 pages so that I can read it?

hi,

i'm using FF (version 98 at the moment) to print local files. It is key to me to edit header and footer for each print! the only solution i found so far to edit them at all, is to go to about:config and for example search for print.print_headerleft. Besides that is not usable at all, it simply doesn't work! The header and footer remain the same. Please tell me how can i change header and footer?

If you delete the, in my opinion much better "page setup", why don't you include all it's funktions in the new print dialog?

another problem is the size of the new print preview! it's much to small! make it resizeable please.

Or just give us back the "page setup". That would be a big advantage over chrome and edge, which suffer the same printing problems.

Thanks

I just bought a new laptop and installed the firefox browser on it. I was trying to log into my account for Elder Scrolls online so I could download the game onto my new machine, but the sign in window would blink and a little white box in the lower left would briefly read "javascript;"

I have no trouble logging on to my account from the site on my older computer, which presumably does not (yet) have the same version of firefox as the newer machine. I was able to log in to the ESO site from my new computer via chrome, so at least I can download the game.

But I'm puzzled as to why Firefox is suddenly incompatible with this site when it never has been before to my knowledge.

Hi, I have set Firefox to "Open previous windows and tabs" and to "Open links in tabs instead of new windows". When the system opens Firefox for me because I've clicked a link in a document, I would like the link to open in a new tab of that previous window which Firefox opens at startup. For many years this was its behaviour. In Chrome for example, this was not and is still not the case.

Recent upgrades to Firefox have changed its behaviour to that of Chrome. When I click a link, Firefox now opens the link in a new window and then opens the previous window on top of that. The link I wanted to follow is behind and invisible.

Could someone check and see if this is related to my system (I'm running Monterey) or if it's reproducible? I can't think of a reason for this change so it feels like a bug, either on my system or in the app itself.

Thanks for any help!

Previously to a mac OS upgrade to 11.6.1, the browser worked fine. Now, nothing loads even though all the other browsers work fine. Pages just display "Secure Connection Failed." I have gone through and executed the adjustments on the "Websites don't load - troubleshoot and fix error messages" page but it still does not work.

I have a website that has MP4 video in a HTML5 video player, with subtitles done in the WebVTT format (*.vtt). I just noticed that, when testing my pages locally on my C drive, the subtitles no longer appear on the movies. They do appear on the website (thankfully). Does this mean that lately Firefox has dropped support for local VTT files? Chrome has always ignored local VTTs, for some reason, which is why - until now - I used Firefox to test subtitles off the C drive. Note: If I link the local page to the VTT file on my website, subtitles still do not appear in Firefox. It could be something else, of course, so just need to know if VTTs are now unloadable locally in FF.

Operating System Ubuntu 20.04.4LTS on AMD® Ryzen 3 pro 3200g 64bit processor. Firefox Web Browser version 100.0.2 (64-bit)

The method I can reproduce sound distortion:

I have clear sound playback through both system HDMI speakers or if earphones are plugged in, verified using the Ubuntu Sound Output test left/right (without distortion)

Then if I open a normal Firefox window and listen to YouTube video for example I have no distortion, if I however open I private window, say to access training material on Microchip University site I suddenly have distorted playback.

Please advise why private window opened suddenly distorts my output sound. Sound suspicious.

in startpage of my ms account all ms apps can be opened...........EXCEPT the app Onedrive. What to do to make this work?????

using MS Edge all is doing well!!

thanks in advance

Issue When opening a link from any other app, the Firefox switches to another virtual desktop if there's an existing Firefox window open.

Reproduce the Issue

1. Set Firefox to default browser
2. On Windows 10, open 2 virtual desktops. Use Task View button in Taskbar or use keyboard shortcut Win + Tab and then click on New Desktop. Now you should see 'Desktop 1' and 'Desktop 2', if Task View is opened again.
3. On Desktop 2, open a new Firefox window.
4. Switch back to Desktop 1 from Task View.
5. Open any link (E.g.: https://www.mozilla.org/) from any other app like MS Word, MS Teams, etc.
6. The virtual desktop would switch to Desktop 2 and open the link on exiting Firefox window.

Question Is there a way to open the link on same virtual desktop in a new window?

Improvement - If it already doesn't exist. Instead of opening the link in existing Firefox window on Desktop 2, open a new Firefox window on Desktop 1 to open the link.

I'm using it for megamenu. It's working fine on Google Chrome, Edge, Brave, and Opera.

It's not working on Firefox only.

I have also put this jQuery between <head> tag. Still, not working.

/*jshint esversion: 6 */ jQuery(document).ready(function($) {

   "use strict";
   // Mega menu (with tabs)
   $(window).load(function(){
       $('.megamenu-tabs').each(function(){

'); $( '.tab-content', this ).wrapAll( '
'); $( '.tabs-nav, .tabs-content-wrapper', this ).wrapAll( '
• '); $('ul.sub-menu', this).show(); $('.tab-content:not(:first-child)', this).addClass('tab-hidden'); $('.tabs-nav li:first-child', this).addClass('nav-active'); $('.tabs-nav li', this).hover(function() { var tabId = $(this).attr('id'); $(this).closest('.tabs-nav').find('li').removeClass('nav-active'); $(this).addClass('nav-active'); $(this).closest('.submenu-content').find('li.tab-content').addClass('tab-hidden'); $(this).closest('.submenu-content').find('li.'+tabId).removeClass('tab-hidden'); }); var highestTab = $('.tabs-content-wrapper', this).outerHeight(); $('.tabs-nav', this).css( 'min-height', highestTab-40 ); }); }); });

Hi folks,

I've asked this same question of Microsoft, as I cannot tell if this is a quirk in Firefox 100.0.2, or in Windows 10 Home, or something to do with what they put in the water here (besides flouride)...

Over the last few days I've had to reinstall Office on this Windows 10 Home system, and had a Firefox update to 100.0.2 as well. Everything working fine up through last night -- URL shortcuts on the desktop would open Firefox (default browser) just fine.

Shut down. Cold boot this morning. Manually open Firefox as usual. Double-click on desktop URL shortcuts (or right-click, Open) gets a real quick hourglass and then nothing. No error, no browser tab.

So I checked: default browser still set to Firefox; .URL filetype still set to "Internet Browser."

I toggled the default browser to Edge, and the links work just fine. Same links. No changes to them.

Toggle it back to the much more privacy-protecting Firefox and... they won't work.

This seems spooky.

Note that the desktop icons for these shortcuts correctly show either the Firefox icon, or the logo/icon for the web page itself (ie, Google Maps). And the toggle of default browser did NOT update the icons.

Any ideas?

Thanks!

latest browser shuts down when I open a new session. After a few seconds it shuts off, I reopen it and its ok until the next time I open my notebook. The without fail it happens again. Began I think with the last update on a Windows 11 notebook.

Just to serve notice that I will no longer be using Firefox as for some reason it no longer reopens ios full screen. It is hugely inept every time I go to Firefox, which I like, to have to open in fullscreen. Why have you done this. I will bet I am not the only one frustrated. Also: why not support line. Communities are a gross cop-out and waste my time. I want to speak to the company and expect them to provide me with a service: not amateurs.

Dear Sir/Madam I have recently started purchased an Oculus Quest 2 VR headset. In order to purchase apps and games for my headset I want to use my PC so I can peruse the software available in the Oculus Quest store However when using the Firefox browser I find that when I link to the Oculus store I end up with a constantly rotating wheel and cannot access the apps/gamessection of the store (Now known as METAQUEST) However when I use the MICROSOFT EDGE browser the Oculus website works perfectly This disappointing as I much prefer to use FIREFOX Could you advise if there is a setting within Firefox which may help or could you comment on why Microsoft Edge works but Firefox does'nt Thank you Regards and best wishes Edward

I guess I crammed it all into the "Subject" line. Working with Windows 11. Outlook appears to be the default for this activity, but I cannot find it in the list of "Default" files for email. Another "gift From MS. Any ideas about how to get Outlook "view in browser" to use Firefox? I have screenshots if they can be used here. Thank you. Greg Schultz

Hi, I use the Outlook web interface on firefox. I keep running into a strange bug. I'll start typing an e-mail message, and all of a sudden, my keystrokes are interpreted as commands instead of text. For instance, I'll type a word with an "n" in it, like "and", and somehow after I type the "a", the interface starts grabbing keystrokes away from the text field, so when I hit "n", it creates a new message, and the "d" ends up going into the text field of this new message. It's very frustrating, because I can't type more than a couple of sentences before the message and interface get screwed up. I've seen this misbehavior for a while, through several updates of firefox. No other web app behaves this way.

There is a very descriptive thread of the problem: https://answers.microsoft.com/en-us/outlook_com/forum/all/working-with-outlook-web-interface-on-firefox/4212cac3-4be3-4295-b325-369ea3d46f2a?page=1

This has been happening to me for many months and through many browser updates. I/ going to have to get rid of firefox soon
