Firefox Support Forum

The Pop-Up for the radio-player of my favourite radio-station is always too big. When I open it, the lower part of the Pop-Up is hidden by the taskbar. When I try to pull the upper part down, to pull the whole Pop-Up-window into the screen, the upper part suddenly jumps down. With a screen ratio bigger than 100% it can happen the whole Pop-Up disappears below the taskbar. The radio-station writes that it is a problem by Firefox. In Chrome the Pop-Up has the right size. (here the site with the problem https://www.srf.ch/radio-srf-virus/ press on "Jetzt Hören")

How can I replace the crappy Linux home page (using Mint 20.0) and replace it with the traditional Firefox homepage? Firefox and Mozilla have been no help at all, which I feel is pretty sorry support for their users. They know exactly what the problem is and why it exist.

services.sync.prefs.sync.browser.startup.homepage = true already

Please contact me at jlannex@gmail.com if you have a solution.

I often find duplicate bookmarks in my folders and with tags. If I have two identical entries and try to delete only one of them, both bookmarks disappear. Why is that, and how do I prevent it fom happening?

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

Hi Guys 'n Gals, As of today, I am unable to log into the Australian Tax office Business Portal or Business Services (BETA) through MyGov using Firefox browser. I can log in through Edge, no problem to both. I've cleared histories, cache etc on Firefox, and it is up to date. I've logged out, and logged back in. When I attempt to enter the email address to log on to ATO using Firefox, I can type the address as far as ".com". The moment I type ".", I lose the entire address, except for the ".". I don't get to the "com.au" part at all. I've contacted the ATO, they have no updates at all regarding issues with Firefox. We are getting close to Plan C (Sledge Hammer LOL). Any and all help gratefully accepted, I do not like edge....... Thank you Trina

I am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

Does anyone know if the screenshot issue with Firefox 88 resolved in version 88.1? I had to rollback to a previous version as screenshot wasn't working properly in 88.

I use a Logitech MX Master 3 mouse, without any custom Logitech or other mouse software. When I press the mouse's back/forward buttons, instead of navigating back/forward, Firefox enter Scroll Mode (more info here). This is the same behaviour as when pressing the middle mouse button. However, I already have the middle mouse button for that! I want the back/forward buttons on the mouse to navigate back/forward. See the attached image for the back and forward buttons I'm referring to: they're directly under the horizontal scroll wheel.

Is there a way for Firefox to register the back/forward button presses as back/forward navigation commands?

When i try to go on addons.mozilla.org it says the connection timed out and sometimes it says i cant access due to page not being secure and some problems with certificate, i tried with another browser but its same thing.

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

My print preview is no longer available, and the new one is too small to see what's on the page. It's useless! Also, simplify page is gone (I understand "Reader View") is the work-around. Also, it's many extra clicks to get to my system print controls to print properly.

Solving the print preview too small would go a long way towards keeping Firefox usable. The other things could certainly use fixing, however.

Thanks in advance! L.

(I have restored the old functionality temporarily with print.tab_modal.enabled preference set to false. Thanks community for showing me to do so! See https://support.mozilla.org/en-US/questions/1322623 if you want to know how.  However, usually Firefox takes these options away soon.  )

Hello, im a web developer and have come accross a problem which only occurs in the firefox browser.

When i design a website, i use the www version of it always, and have redircts for all other instances, eg; mydomain.co.uk > https://www.mydomain.co.uk http://www.mydomain.co.uk > https://www.mydomain.co.uk https://mydomain.co.uk > https://www.mydomain.co.uk

So they all end up at the secure www version of the website. This is done in the .htaccess file and works great in Chrome, Edge, Explorer etc just not firefox.

In firefox i get the error

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to boothandco.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the web site, and there is nothing you can do to resolve it. You can notify the web site’s administrator about the problem.

Ignoring it then procceeds to the full https://www. but that warning screen will be enough to put potential visitors off no doubt.

Is there an "easy fix" for this or is the only way to solve the problem to use up more SAN's and double up on www and non-www versions of each website?

Any help is greatly appreciated.

Thanks Chris

On old tabs, where I have opened google.com, there is infinite captcha! Once I solve it, it will immediately return back. I tried delete cache and cookies and restart PC. Nothing helped! I read on reddit it is known issue with Firefox!

Hello-

I recently did some house cleaning and removed cookies, cleared cache, etc within firefox on my desktop. Since then, gmail.com website will load but when I click to sign-in, no accounts will work within the browser. It continually has the spiraling blue bar above the login screen and gives a "Something Went Wrong" message, which I've attached as an image.

I did some searching through the forums and found a standard response given by the community:

------------------------------------------------------ "You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button
   press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
   press "Command + Shift + R" (Mac) 

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" for websites that cause problems:

   Options/Preferences -> Privacy & Security
   Cookies and Site Data: "Manage Data" 

"Clear the Cache":

   Options/Preferences -> Privacy & Security
   Cookies and Site Data -> Clear Data -> Cached Web Content: Clear 

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

   make sure your extensions and filters are updated to the latest version 

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

   switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
   do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again. " ---------------------------------------------------------

I have performed all of these tasks to no avail. Chrome (in the same desktop) works, my android pixel 2 works, as well as an ios device. This only happens in firefox. I have done a full refresh, removed all add-ons, turned off hardware acceleration. I don't use themes.

Has anybody else ever had this issue or can offer any advice? To be clear: all other websites and their respective logins seem to work. Haven't run into any other problems except gmail (and google accounts tethered therein).

Thanks!

I'm running Mojave 10.14.6 on a MacMini (late 2018) with 64 GB 2667 MHz DDR4 and Firefox v86.0 64-bit.

I need to disable Command+D that's currently used to "Bookmark This Page".

I need Command+D for another use.

I've searched about:config for "bookmark" and get a lot of hits, but I can't tell which one controls the setting for Command+D.

Or . . . am I barking up the wrong tree?

I want to disable Command+D.

Leaving the ability to mouse up and click Bookmarks > "Bookmark This Page" is ok.

I just need to disable the keyboard shortcut Command+D for "Bookmark This Page".

Anyone got a "howto" for this?

Thanks!

When I try to open a word document from a website via firefox it will not open. Constantly gives me an error message. Been in touch with microsoft word and its not an issue on their side.

I can open the documents via microsoft edge but not fire fox.

I keep getting the same error

hello there and good evening:3 my husband and i are having this repetitive and extremely frequent bright yellow pop up with a robot that states "a webpage might be slowing down your browser." then the option to wait, or stop it. i've ran out of patience with this notification to the point to where even though i'de hate to, i would have no choice but to switch back to chrome just to stop being spammed by this pop up while im trying to relax. it happens more frequently on youtube and walmart.com, and i just want it to stop because it seems as if when it does show up, once it starts it never stops, and it actually slows down my webpage to the point of becoming unresponsive and stalling/crashing my only webpage open at the time. my husband has the same issue and we both use windows desktop. it only started appearing after the latest update. please, can someone help me make this thing go away? its very stressful and i cant browse in peace anymore on firefox. yes we have turned off all background processes, and we both have scowered settings troubleshooting for hours at a time to no avail, it just never stops and it behaving like a really bad bug.

hi all, please help. from version 89.0 every time I print a PDF document (portable document format), firefox print to center page, how to set the left margin ?

Suddenly Outlook has added two columns to the left hand pane.

Is it possible to get rid of them as they just clutter up the page?

I have attached a screenshot and hope it comes out.

Thank you for your help.....Anthony
