Firefox Support Forum

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

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

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.

In the last week or so, iPlayer, All4, and Spotify (that I know of) have stopped working in the Firefox browser. All4's error suggests DRM isn't enabled, the others just say try again. Roll20 hasn't been working for even longer (more like months). They work in Microsoft Edge and Chrome. Youtube is still working, as are video players in social media.

I have tried the following solutions:

• Firefox is up to date
• Windows is up to date
• Updated graphics drivers
• 'Widevine Content Decryption Module provided by Google Inc.' is set to 'Always Activated' and is up to date
• 'Play DRM-controlled' content is ticked in about:preferences
• Checked if anything changed if either of the above were turned off (it did not)
• media.eme.enabled is set to true in about:config
• Put Firefox in troubleshooting mode
• Turned off my addons (including uBlock Origin) manually
• Tried in a Private Browsing window
• Turned off Tracking Protection
• Restarted my laptop

Nothing has fixed the problem, or given me any more indication of what is wrong. I don't know how to a) fix or b) find the problem. All I can think is that it may be related to the recent changes to Chromium regarding ad-blockers? But no one else seems to be having the same problem so I doubt it.

Hi, can you help? I can't access morphy richards website from my phone and my pc through Firefox. I can access it through Microsoft Edge on my pc and my Samsung Internet app on my phone but not through my Firefox app or windows 11 Pro desktop pc. I get this message on my pc

Hmm. We’re having trouble finding that site. We can’t connect to the server at www.morphyrichards.com. If you entered the right address, you can: Try again later Check your network connection Check that Firefox has permission to access the web you might be connected but behind a firewall

and this message on my phone through the Firefox app

Address Not Found. The browser could not find the host server for the provided address. Check the address for typing errors such as ww.example.com instead of www.example.com.

If you are unable to load any pages, check your device’s data or Wi-Fi connection. 

Steps I have taken is clearing data, history and cache on pc, turning off mcafee firewall. I use my pc through a wired Internet connection and my phone through Wi-Fi and data and it's the same on both I can't access the website. Like I mentioned I can access it no problems through Microsoft Edge on my pc and Samsung Internet app on my phone so I have now pinpointed it to Mozilla Firefox being the issue, also this is the only website I have issues with. Please can you help? Regards, Steve

I was having trouble with Firefox freezing and needed to close it with Task Manager and reopen it whenever this happened. On one of these restarts, only a few of my windows opened up with the new session. All of the other open windows vanished. They're not in my history or my recently closed windows at all. There are three specific windows of the lost windows that had data I was actively using and don't want to lose. The URLs would be enough. I was also using the other windows, but I can re-find that information easily enough.

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've recently switched back to Firefox from Edge and have run into a frustrating issue.

When I try to print documents from Firefox, the "Color Mode" in the print settings is grayed out so I can't select B&W.

This same problem exists both on my MacOS laptop + my Windows 11 desktop. Additionally, they are connected to different printers on different networks. It also occurs whether I'm trying to print a PDF or anything else in Firefox.

Based on this, it appears Firefox is the culprit here.

Any ideas on how to fix this?

Firefox Version: 108.0

Twitter not working properly on Firefox (Volume on videos can't be changed, hovering over buttons doesn't do anything and font looks a bit off, could be just Firefox font or something) works on chrome and other browsers.

Video link that shows this of: https://youtu.be/3Lk83z-ozVI?si=uWYjGhFk294Hn9Dj

I've set custom fonts through Settings > Fonts > Advanced, but the fonts I have specified are not being used on any websites even if I uncheck the box that says "Allow pages to choose their own fonts, instead of your selections above". For example, I've set the default sans serif to Source Sans 3, but websites use Arial regardless of the settings. The only custom font I've gotten to work is Segoe UI (the UI font on Windows); all other just fall back to Arial. The problem persists even if I disable all extensions/add-ons. I'm also experiencing the problem for non-Latin scripts; I've tried to set the default Bengali font to Noto Sans Bengali, but websites are using Vrinda instead.

I'm running Firefox version 120.0 on Windows 11, any help is greatly appreciated!

I get this message when trying to access this site: "We can’t connect to the server at www2.optumrx.com"

I can then go to another browser, like Edge and I have no problem accessing the site. I am using a Windows 11 Lenovo computer running Firefox 120. This problem just started to occur.

It is ABSURD https://bigthink.com/neuropsych/tab-overload/

Why browsers UI didn't change from 1999, when we know it causes tab overload, brain has to constantly filter everything it sees and how we engage with information is cruical in this age. All we get after 24 years are 4 categories to group tabs. I had even 3000 tabs peaking, average 1000+ reading philosophy. Einstein said: "human stupidity is infinite"...

Bookmarks are atrocious, you cannot even scroll panel with mouse holding bar, cannot cltr+f for existing folders, bookmark manager doesn't find existing folders, it sorts folders with bookmarks together contained under a folder... Doesn't have even tags, with thousands of bookmarks and folders, it would take 10 minutes to find fitting folder... I didn't also find any good 3rd party solutions really...

There are tab manager addons, but if you have again a lot of different tabs, it won't help you, it is useful for short-term workloads, but then you have nothing to store things in more permanent way. Also making notes all the time with reading would cost too energy especially if you need to research many things together... There is prototype of AI that saves all things based how you hover cursor over text etc. It would be great if it supported AI tracking and then highlights important info and makes notes, it is not publicly available yet in some solution...

Note taking programs suffer from same issues, missing core features, chat with AI is still very rudimentary and won't help you bring some small notes or piece of info you read 2 years ago, or something specific on-demand... When note taking program cannot even collapse notebooks on main view and you have seeing like 100ths different entries, or doesn't show available tags and selecte multiple of them quickly together under each notebook...

bottom line: there is no tab management really and all addons are really basic and doesn't support long-term intelligent storage for a lots of tabs so you find what you look for later, bookmarks are unuseable after certain amount (again no good third party solutions i saw...). Note taking programs all suffer from same issues, missing core features, again it is impossible to navigate any else way except using tags, but then if you have many then what, you cannot use tags to find thing nested under 20 other things, some specific bit of info, it will still be vehement to sort, if you cannot use multiple things together like jump to notebook and then see all tags what are there available, which would work better, you cannot remember all tags in each notebook you have... All solutions that exist missing core features and are overly simplistic and vehement... This gave me executive dysfunctions...

And if i give feedback to devs of absolutely logical core things, or what could be better and is missing and what stems from purpose and function and is self-evident: they tell me i am brilliant, it is ABSURD... Don't know what to say... 2023 there is still not way to efficiently make notes, capture knowledge... Even my former 160IQ friend said he had millions of files on disk basically has no idea where anything is... Learns everything from memory as he reads it before he goes to next things... It is really dumb in information age, so much interesting things from what we read is permanently lost, there is no really good way to capture info and link it and bring it easily later... Just diet, or healthy lifestyle can be complex and many different areas that are related and are under 20 other things... IT is impossible to find something later... It is absurdly bad how devs don't realize these things and normal ppl tell you you are crazy if you have over 10 tabs, while it was shown today work can generate easily over 100 tabs and it is important to manage information well... Yet there are no solutions, would have to hire programmer for every small thing i notice somewhere is missing, or is vehement useless basically...

Greetings!

This is so strange.

My Screenshot Icon in FF 120 is gone. Tried adding it back, but it's not there under More Tools -> Customize Toolbar. Overllayed Firefox with a new install - no change. Disabled/enabled extensions and themes. No go.

Am I the only one? Any ideas?

Thanks. :)

Hi,

On September 15, 2022 I created this thread here on Firefox Support Forum and now I finally have an answer to the question, but as we can see my thread was archived and I can't update anything, so I decided to create a new thread just to mark my previous question as solved and bring it an answer.

I contacted Mozilla Firefox developers and got a response: Firefox is no longer integrated with Gravatar. Considering this, I can tranquilly say there is no bug or problem with my account as I thought. It's a pity that Firefox no longer support Gravatar integration, and even if I use an old version I will face the same "issue" because the Gravatar integration was a online feature linked to the Firefox account*, not to the browser itself.

Info source: https://github.com/mozilla/fxa/issues/15665

Admins can now archive and close this thread, I only ask to keep it online to help who may need this information in the future. Thanks.

• Actually I made a mistake when I wrote this, the Gravatar integration was an online feature linked to the Mozilla account, not Firefox. James explained the distinction on #4 post of the current thread.

Last edit: On January 31, 2023 I created this thread on r/firefox but no one answered precisely. This current thread here on Firefox Support Forum also solves what was asked on reddit. The thread created on January 31, 2023 and posted on r/firefox was archived as well, like what happened to my thread with the same theme here on Firefox Support Forum, then I also created a new thread on r/firefox to mark my question as solved.

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

When switched to mobile hot spot from wifi [and viceversa] Firefox can't load websites but other browsers can. I am facing this issue recently like from a month or so. Before that all working fine. I have already tried the troubleshooting steps from here https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can, Still no luck! Edition Windows 11 Home Single Language Version 22H2 OS build 22621.2506

Note:Whenever i switch to mobile hot spot i have to restart laptop to make Firefox work.

Is there any permanent solution for this problem?

I want to be able to start a live stream in Mighty Networks - all seems to work, except the go live button is blanked out. I tried all the usual up to reinstalling firefox and generating a new userprofile in windows 11 and getting a brand new firefox version running in the new userprofile. With other browsers like chrome it just works fine.

On my latptop running windows 10 firefox does not encouter this problem.

Any suggestions are very welcome, I can of course switch browsers but would prefer to see this issue resolved.

Curious to hear if any other users encounter the same issue,

Thanks for any help provided,

Bart
