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'm running v100.0.1 (64-bit) on Win10. I've seen others report this problem but haven't found a fix listed anywhere. <Ctrl-P> or Menu->Print results in the same problem. The print overlay starts up (say Print in top right corner), spinning wheel above Preparing Preview in the center of the overlay... Never ends. I have to Esc to get out of it. Happens on any page. Print dialogue works fine on same pages with Chrome and Edge.

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

I use a laptop with Fedora 36 installed. Firefox is version 104.0.1

Until a few days ago, there were no problems with video display. But since a few days, video content that is offered by the news site from NOS (Dutch television) is not displayed anymore. I only get this error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

Also some content on Youtube aborts. For example loading https://www.youtube.com/watch?v=qq0BUiEs3JM results in this error: Er is een fout opgetreden. Probeer het later opnieuw. (Afspeel-ID: Ui0fzPxdSexgYcZ4).' (An error occured, try later again).

When using the Chrome Browser both websites can be used without giving errors implying that all the codecs are available.

How can I detect why video is blocked?

(Twitter also gives problems. After a fraction of a second, it stops displaying video)

Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

I was directed here from Mozilla Connect. Since the update a few days ago, my Firefox browser keeps freezing permanently. It seems to happen mostly when I interact with Google Search (sometimes just loading Google will cause it) but it does happen occasionally on other sites. When it freezes this way, the only fix is to End Task and reload. It will successfully reload to the state it was in just a few seconds before freezing. I'm on Windows 10. I keep everything (OS, browsers, etc.) up to date, so I doubt that would be a factor. I wonder if there could there be an issue with a Google-based script (hence it occurring on other sites)? I don't know how I'd test for that.

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

This sounds like it's a Meetup problem, and in fact it may be, but now I am having doubts.

The problem is that I can't upload photos to a Meetup event. (This will mostly just be a problem for Meetup organizers.) When I click on "Save photo", nothing happens. No error message, nothing. It's as if the "Save Photo" button has been disabled. Firefox is my browser while I access Meetup.com, and I have the latest and greatest version of Firefox.

I contacted Meetup and they haven't been able to solve the problem; they suggested that I clear my cache and my cookies and try again, but I get the same result. HOWEVER, when I go into Microsoft Edge, I can upload photos with no problem. So I have a work-around: use Microsoft Edge to upload photos. So my question to you centers around: why does this work perfectly in Microsoft Edge, but it doesn't in the latest version of Firefox?

To test the possibility that it's a bug on my personal desktop computer, I went to the public library and tried the same experiment, with the same result. So I don't think it's problem with my personal desktop computer.

One other piece of information: the exact same thing happens (failure to update photo, that is) when I have the photo open in another application (Photoshop), even if I try to "save photo" to Meetup in Microsoft Edge. Then when I close the other application (Photoshop in this case), Microsoft Edge lets me "save photo."

I know that Firefox really doesn't want me to try to revert to a previous version, and it makes me nervous too, but I am suspecting that something in the latest Firefox version actually introduced a problem. (Or maybe triggered a Meetup bug of some sort; I still haven't located the problem.) I've been on Meetup.com for years, I've had Firefox for years, they've worked together to upload photos in the past for years.

If you want to get into the details, below, for what it is worth, is my initial question to the Meetup support people (with whom I am still in a conversation).

- - - - - - - -

I can't upload a photo for my event. In fact, I cannot upload a photo for any event at all. I deleted a couple of photos and an album because maybe our group had too many, but that didn't work. I can't even upload a photo that I had previously uploaded to a different event, so I don't think that the problem is with the photo itself.

Here's what happens. 1. Edit the draft of my meetup. 2. Click on "upload photo." The photo is 1827 x 1009 pixels, total size 63 KB. 3. I click on "Upload photo", then in "add photo" I click on "upload photo" again. I browse for the photo and select it. 4. The "crop your photo" screen appears, with the selected photo in it. It's already the size I want, so I click on "Save Photo".(Cropping doesn't help either.) 5. Nothing happens. No error message, nothing. The only think I can click on is "cancel," which takes me out to the previous screen. - - - - - -

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

I am using firefox v104 on linux mint. This problem happened this evening. Every tab i open shows the same error.

I tried the solutions suggested in other similar forum posts like >safemode (tabs still crashed) >driver update (my drivers are up to date as far i can tell) >deleting cache and reinstalling firefox (tabs crash). I took a backup of my bookmarks and extensions as suggeated in another forum post. > one youtube video (https://youtu.be/F9VaXwSB_po) suggested toggling media.cubeb.sandbox in the config section. The tabs started loading after that but it wasnt that useful as i wasnt able to get any videos to play in the browser.

Also, i don't really know if the issue is related, but chrome tabs were also not loading or responding ('Page unresponsive' error).

Please help. Thank you :)

For the past 8-10 days, every time I try to log-on to: https://selfservice.telkom.co.za/rococo/public/content/interstitial I click "Login" under the Mobile & Home heading and I receive the following message returned.

Bad Request The request could not be understood by server due to malformed syntax.

I have used MS EDGE browser and do not get the same problem, it log's-on OK.

As such it seems that it is a Firefox problem.

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

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

I noticed some peaks of usage on both internal and dedicated GPU while watching videos on YouTube. This happens only when watching videos not on Full Screen mode. I tested also with chromium but there's not this issue. What is causing it? How can i stop this behavior?

I recently got a new computer, and in trying to get all my old accounts and what not synced up, I noticed that Twitter videos weren't playing for me and giving me a generic "The video could not be played", which was odd and annoying, but not the end of the world. I then went over to Twitch and got the "Your browser encountered an error while decoding the video. (Error #3000)". Meanwhile, Youtube works perfectly fine.

I tried clearing cache/cookies, tried on incognito mode in case it was an issue with one of my extensions, all to no avail - when I swapped over to Edge just to check if it was a computer issue versus a Firefox issue, both sites functioned in Edge just fine. Is there anything else I can try troubleshooting in Firefox to see what's causing this short of trying to uninstall/reinstall again?

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.
