Firefox Support Forum

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I'm having a number of issues with my Firefox out of nowhere.

1. My mouse will no longer scroll, nor will my keyboard arrows. I must use my touchscreen. 2. I have "new tabs" instead of "new windows" selected, yet if I click anything, it goes to a new window. 3. I cannot close tabs without right clicking. 4. I cannot SWITCH tabs at all. 5. I cannot close Firefox without going to my start bar and right clicking. 6. Firefox seems to be aware something is wrong, opens up in a troubleshooting mode... and then doesn't troubleshoot.

(It is entirely possibly my infant slammed on the keyboard and changed a setting I can't find.)

Hi, my Firefox keeps crashing on using youtube (on openening youtube.com or any site which integrates a youtube video). My crash report ID is as follows: bp-d25e9417-a29a-4ce2-ac69-1e8460220329 Is there anything I can do? Thx a lot, Maike Scotland

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

I got a new computer recently and it was already upgraded to windows 11. I downloaded Firefox because it is my main go-to. It worked for a few days then all the sudden, it just stopped loading, if I tried to search something it would just load forever and never show up. Even dev tools would not display, it just was like in a frozen state, I tried downloading the Developer version of the browser, nope! Deleting all program files, Nope! Then when I tried to use edge, smooth as can be. What the heck is going on here?

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.

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?

Hello! After updating to the latest version of Firefox (100.0.2, 64-bit), I notice that Google search stops working every now and then. By stops working, I mean I can't use their website https://www.google.com or search using Firefox's address bar or search bar. Searching with other search engines like Bing is working normally. In order to get Google search working again, I have to close and restart Firefox. However, after some time, it stops working again. How can I fix this problem?

After I log in to the Office and try to enter Word online (https://www.office.com/launch/word?auth=1) , I am constantly redirected to the home page , (https://www.office.com/?trysignin=0). I already deleted cookies and add-ons, reinstalled firefox

I'M trying to open Realtor.com and I get this message: Application error: a client-side exception has occurred (see the browser console for more information). Can't seem to fix it. Can you help?

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.

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

A white screen occurs when browsing the web. If you turn off "Use recommended performance settings" and "Use hardware acceleration when available" the problem is fixed, but then the browser slows down. Can this be fixed in another way?

Hi, I'm having a problem with my Firefox where it doesn't let me change some of my settings. This is my home PC and I've already tried running Firefox as admin and the settings are still locked. I have reset it many times and haven't installed any extensions. I can't find anything online about this.

Just recently, I've been having problems with websites run by Cloudflare. Whenever I attempt to access ANY website that is operated by Cloudflare, I'm often presented with a blank page, or a Firefox error message. Sometimes I'm even presented with the DDoS protection error, even though my computer is clean having being scanned by Kaspersky and Malware Bytes.

I reiterate this and say that it's only Cloudflare sites that are causing problems. Very occasionally they will work for up to an hour or so but most of the time it is error messages or blank pages. Interestingly, other web servers such as Amazon, OVH SAS and Akamai all run with no problems so I wonder what is Cloudflare's problem? Is this something to do with my browser or the web hosting services?

Firefox always uses excessive GPU memory when I watch video and livestream. about:memory shows that the explict GPU memory allocation is only about 200 MB but in the task manager the GPU memory usage is 1GB, and the latter doesn't decrease even if I close the tab. I suspect that this is a memory leak. I searched for Bugzilla and found a similar issue that has been existing for years: https://bugzilla.mozilla.org/show_bug.cgi?id=1386177

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

Hello,

When I try to log in to my one of my bank's secure website, firefox is not connecting. I can connect with chrome and edge. Firefox does connect with other bank and investment accounts websites. I am having the problem with this particular site. I had faced this problem with another website (non-banking, but secure), but it corrected itself in a few weeks.

I appreciate your help.

Thank you.

Dave

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.
