Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

Hello,

My firefox has started glitching like crazy. It's like it's trying to constantly resize itself. It has been happening since I opened it on pop-up mode on my Samsung Fold 5, but I've tried reopening it in pop up mode, and all other modes, restarting my device, reinstalling firefox, everything I can think of and it's still doing it. Some of my icons are a mess too. I really don't want to switch to another browser... Anyone have any bright ideas? Adding screenshots to show issue.

Kindest regards,

Matthew Trigg

I'm running Firefox 116.0.2 on Xubuntu 20.04.6. A day ago, it started loading at startup for no apparent reason. I don't want it to that. It's not my default browser, and it is not selected as such. It is not listed in any startup folders or in application autostart in system settings. I tried the winregister and auto update fixes using about:config, and no joy.

Does anyone have any suggestions? It's past annoying.

Since a few days, it is not possible to copy-and-paste any external text or content into the text field of WhatApp Web on Firefox. It works fine on Chrome. Also text manually copied from a previous WA message can be pasted.

We tried on other PCs with Firefox and Chrome, same situation. So it seems to be a problem of Firefox latest version.

I can go to xfinity email but when trying to access email it will say the service is not available right now. Before the latest firefox update I had no problem with accessing comcast email with Firefox. I can access email thru chrome without a problem. I have cleared cookies and cache but it made no difference. What do you think is going on. Thanks.

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

When I open `about:preferences` tab, `Downloads` directory is created in my home directory, despite my downloads directory is different. I've read issue 474718 which states that it was fix but i still experience it. Linux x86_64

I was told to ask for support here rather than at bugzilla.

User Agent: Mozilla/5.0 (Android 10; Mobile; rv:109.0) Gecko/116.0 Firefox/116.0

Steps to reproduce: 1. Install Fennec from F-droid 2. Open browser 3. Observe splash screen 4. The original logo is back

Actual results: 116.2.0 changed the startup splash screen back to the regular logo. I actually rather liked the minimalist splash screen logo we had for a few weeks prior.

Expected results: Is there a flag in the config that I can change to get back the minimalist logo?

typing does not match keyboard When I type a character I get a sequence of qwerty keyboard symbols from hitting the same character. for example when hitting "a" I get the following (I must cut and paste to get my typing in this support page. 34567890-=qwertyuiop[]asdfghjkl;'`\zxcvbnm,./-+\123456789

After a recent change of my website's name registrar, Firefox (both on Linux and Android) has been running into issues finding the server/address. I suspect this has something to do with DNS, whether it be DNS over HTTPS (DoH) or otherwise.

Specifically, this seems to happen when DoH is on (as shown by about:preferences#privacy). I have confirmed that `curl --doh-url <cloudflare DNS query> <my website>` also fails to resolve the request.

This leaves me with a few outstanding questions:

• Do I have any control of whether the DoH request fails? Is this something I can fix through my host or name registrar?
• The TRR mode shown in about:preferences#privacy appears to be different than the one shown in about:config (2 versus 0, respectively).
• Shouldn't Firefox be falling back to normal DNS? I have confirmed via `curl` that my website works fine over https.

Firefox and curl results for Linux confirmed on two machines on the same network.

I also posted this under "Tabs."

All of a sudden I started getting a strange download message, a download which didn't show up when I looked for it. Since then, when I press "+ New Tabs," a new tab doesn't open. A new tab opens only when I've clicked on a new link for a topic.

I cleared the cache, restarted my phone twice and un-and re-installed Firefox twice. I was originally synced with Firefox on my other phones, but I don't want to sign in again with that email until this problem is fixed. I haven't opened Firefox again on my previous phones since this all started. I'm going to cry if those versions are "infected" with this problem as well. I just can't erase all the data I've previously accumulated within Firefox on those devices, either.

Now I've looked in Firefox Support for this problem and I've looked again and again for a way to restart in Safe Mode, but I can't find it. Could someone please help me diagnose and fix this issue?

Im using Firefox android on my new pixel 7. I found that the 'add to home screen' option is not available on the ... List. I searched for solution. Someone say click on Install option. But there's no install option either.

The add to home screen is available on my old moto phone

Does anyone have this same issue and have a solution how to fix this? I very much appreciate all your help!

Using MX-21.3_ahs_x64 Wildflower. Since upgrading Firefox to version 116.0.3 all links within www.onlinetvrecorder.com do not work anymore. No messages, no hints what happened, just not working. Vivaldi has the same problem, Chrome works. I have asked in mozillazine, but did not get an answer.

I have an account at Walmart.com. After the last time I placed an order, something changed. Now, just for simply going to their online site to browse, the page immediately rolls over to a login page. I cannot access the site simply to shop at all, without Walmart forcing me to sign in. This is annoying enough that I am considering canceling my Walmart account and shopping with other retailers. There is plenty of competition out there. This does not happen (as far as I know) with Chrome or edge, the browsers that do not prefer to use.

Hi, I have tried to create a google account two times. Each time Firefox didn't save the google account name.

Firefox did save the password though. Just the username is empty. So, the third time I will write down the username.

I know how to create a Google account. Pretty sure it will work. My question is, why is this happening? Am I paranoid thinking Google doesn't like to support Firefox?

Best regards

Since a week or two my Firefox tabs are crashing more and more often. At work on MacBook and at home on PC.

Deleting the cache and cookies and even starting in Safe Mode are not helping - in fact while writing this very message had 5 crashes meanwhile!

Don't know if you can access the crash report: https://crash-stats.mozilla.org/report/index/4cd570db-d90d-4fcb-aee6-0a1660230818

I am using Firefox for windows on my laptop and I have this issue where it stopped filling in my credit card information. I tried to follow the steps of turning it on/off in settings, except no "Forms" or "autofill" appear anywhere in my settings, nor privacy & security. Going into config, it appears that form and autofill for credit cards are both switched on and available. My browser is updated and everything else seems in order. How do I fix this?
