Firefox Support Forum

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

From today 4 march when I try to record a voice message on chat from facebook appear an error saying an error as occurred. On Chrome it work, from facebook app it work

I even tried other facebook ids and firefox profiles and ever the same. Even disabled the anti popup ublock

In all case I haven't added any conf or adon or other inside firefox, I use same conf as ever and from many years.

Today messages from microphone in chat does not work and facebook say an error occurred Is written in italian but say what I said

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

I set up my Home Page with 3 rows of my own shortcuts (sponsored shortcuts are turned off). All were pinned and alphabetized. If I go a couple hours without using Firefox, about half of my shortcuts will have been replaced with others. None will be in order. Have tried setting up the Shortcuts several times, is really getting exasperating. Is there a simple fix in about:config?

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I always set Firefox to open the previous sessions tabs when starting. For some reason during the start up over the past several days Firefox opens to the home page only. I then have to search the history to find the closed tabs. Except for this problem, Firefox is working perfectly.

Does anyone have any suggestions as to why this is going wrong and a possible way to fix it?

The layout on the Roblox website, https://www.roblox.com Has appeared to break, I've seen the website on Google chrome and Microsoft Edge and it's good to go. I am not aware as to how this has happened. I have disabled every Addon I have, This issue is not caused by the Addons I have installed.

CTRL + F5 has Fixed My Issue! Thank You cor-el!

As I said in the Subject I just bought Total AV this month, now its disabled on Firefox. Is this a permanent action? or is this a temporary action? How can/will I get my Antivirus back in action on Firefox?

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

i have just downloaded Firefox and i go to open in and it flashes open an close immediately. the occurs every time that i open the program. i have reinstalled it multiple times to see if that's the issue, used the Microsoft store to download it, the website, i tried to get the beta that didn't help and i was just wondering what the issues was and wondering if you could. i looked in the error message folder as well and its empty.

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

Hello,

Clicking to open Firefox gives me the following error message:

Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0

Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631

Thanks! Julie

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 understand that the "Bookmarks Menu" Icon (see attached pic) can be used and then: 2) "Manage Bookmarks" can be selected (to get to the "Manage Bookmarks" <selection> screen).

But is there a 1-click Icon solution to access "Manage Bookmarks" (other than the keyboard one)? Or is there a link address that would access the "Manage Bookmarks" screen directly?

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

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
