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?

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.

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.)

Firefox (97.0 64 bit, windows 10) destroyed all my previous tabs (4 windows lots of tabs) when I opened it despite always having "Firefox will" set to "Remember History". It just opened one window with the Home page.

Trying to sort it out using restore all tabs and then all windows, it just made the problem worse and the restored tabs eventually stopped restoring so now I have useless json files.

The files I have in my profile are:

previous.jsonlz4 15/2/2022 18:46 recovery.baklz4 15/2/2022 19:10 recovery.jsonlz4 15/2/2022 19:10 (this file changes its name from bak to json and back to bak again, very odd) upgrade.jsonlz4-20220119190439 26/1/2022 00:23 upgrade.jsonlz4-20220126154723 29/1/2022 04:31 upgrade.jsonlz4-20220202182137 12/2/2022 17:40

Is it possible "previous.jsonlz4" may have all the windows and tabs that I lost?

If so, how could I get Firefox to use it when I next open it? (assuming if I close this browser it won't overwrite the "previous.jsonlz4" file??).

Also could I use the upgrade.jsonlz4 file to try to restore all the windows and tabs that I lost? The windows would have been much the same on 12 Feb as they were today before the destruction.

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 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 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

Hi, so I recently installed arch Linux and want to use Firefox as my browser. However ever since I installed it, it takes a long time to launch the program. It consistently takes just over 26 seconds to launch. After it's open everything works fine besides that. Also when I launch Firefox from the terminal I get this message "ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs" I have been looking at some help threads but I can't make sense of what they are talking about. Hopefully this makes some amount of sense to you.

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

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.

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 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?

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

When typing, Firefox will lag and not display the words until much later, making it hard to know what I'm typing. This applies to any app that I'm using on the browser. For example, I typed this whole paragraph before a single word appeared, and even then, it still took another 30 seconds to actually appear. I've already reset, refreshed, uninstalled and reinstalled, updated, everything like that. I have a couple extensions, AdBlock, Honey, WebRTC Lead Shield, and Return YouTube dislike. But I ran it in safe mode and the issue was still there. I'm running the latest version of Windows 11 if that makes any difference.

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.

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

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?
