Firefox Community Forum

I am trying to troubleshoot a problem with high CPU usage by Firefox when using Mozilla VPN - VPN ON.. Problem occurs when starting in Safe Mode, and still occurs after performing Refresh. Problem can also occur just by changing to a new tab. Problem does not occur if Mozilla VPN is turned OFF. Problem does not occur with Microsoft Edge. Mozilla VPN Support said it is a Firefox issue, and recommended contacting Firefox if safe start or refresh did not help.

Below is a link to a startup session. https://share.firefox.dev/3DEft5k

Hoping that someone can help me solve this issue. Thanks!

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

I have a new dell computer with windows 11. My other computers with windows 10/11 work fine with FireFox but this machine will not load my email website. It must be a setting on this machine.

try loading webmail.shaw.ca use the account bubbleman@shaw.ca password FireFox.

(it is a dummy account for problem solving)  When you click sign-in, the button turns grey for about 5 seconds, then turns blue again.

inspect(q) shows the following error message

Loading failed for the <script> with source “https://siteintercept.qualtrics.com/dxjsmodule/8.372e3f9662e7442947d8.chunk.js?Q_CLIENTVERSION=2.22.0&Q_CLIENTTYPE=web&Q_BRANDID=webmail.shaw.ca”.

I tried following the Configuring Windows 10 Firewall and deleted firefox, then put it back.. My ISP (Rogers.ca)says use a different browser. I have been a confirmed user since Netscape days! I am not very knowledgeable with Windows so any help that you may give me would be appreciated

Thank you for any help that you can give me

On YouTube tabs, if Firefox memory usage starts climb (ie. more than 3-4 tabs active), there are janks for a few seconds preventing me from interacting with the YouTube tab. This jank does not happen with other tabs (can even interact normally with other tabs while the YT tab is janking). Attached is a profiler report.

Running firefox 133.0.3 cannot get the review checker icon to show on amazon, bestbuy, or walmart. about:config options all "true" or enabled. Running addblock plus but turned off for amazon without any change.

Das u.a. Bildschirmfoto zeigt die Buttons der Startseite. Einige davon sind verschwunden. Das leere Button mit dem +, mit dem man neue Buttons einfügen konnte, ist ebenfalls nicht mehr vorhanden. Wie komme ich wieder dahin, weitere Buttons einzufügen?

I updated to 133.0.3 just now and Firefox will not load any pages in new tabs. The only tabs I have open are the ones that were open when the application restarted with the update. For example, I could not open https://support.mozilla.org/1/firefox/133.0.3/WINNT/en-US/firefox-help to report this bug because it was not already open (I am reporting to you using Brave). This is happening in both new tabs and new windows.

I've been using FireFox to login to nytimes.com for many years. Recently, the nytimes.com website hasn't been working properly. It works fine using Edge.

Symptoms are: (1) The zoom level at login and the zoom on going from page to page is very inconsistent. (2) Clicking the Account button does not open the account settings page. Instead it causes the screen background to become grey.

I restarted FireFox in troubleshooting mode, but this did not improve the behavior. I have a single extension (Adblock). Disabling Adblock on nytimes.com also did not improve things.

I get this an awful lot with Newmax, with or without my vpn, makes no difference, and it also makes no sense. I can't believe that a major news site is a security threat vis-a-vis my dinky linux computer in Virginia. What's going on?

Hello everybody, I'm facing an issue with an icon appearing on some sites and propagating down to the print out of the pages. Let me give an example: I'm interested in an article published on: https://www.electronicdesign.com/technologies/analog/article/55246421/modeling-on-mondays-nonlinear-spice-models-of-vacuum-tube-triodes-part-3?o_eid=9960G5790701E5D&oly_enc_id=9960G5790701E5D&rdx.ident[pull]=omeda|9960G5790701E5D&utm_campaign=CPS241216087&utm_medium=email&utm_source=ED+Power+%26+Analog When I open this page, an icon appears in the low left corner. And when I try to print the page, the icon appears on each page. If I use the simplified print mode, a kind of background of the icon (white box) is still visible on each page and can hide the text behind. On top of that the images no longer appear in the print out...

Any help to sanitize that is welcome.

I want to know how to adjust audio (treble/bass balancer) for videos playing in Firefox. Your page at https://support.mozilla.org/en-US/kb/control-audio-or-video-playback-your-keyboard#w_what-is-the-media-control-feature refers me to https://specifications.freedesktop.org/mpris-spec/2.2/ but this URL is a 404. Is there another page that might help? Thanks.

i recently noticed that my audio is stuttering a little bit on firefox desktop, expecially on youtube. i already tried the app on incognito mode withou any extension enabled, notthing worked. can be the last Nvidia driver? can be a recent (1 month more or less) mozilla update? can you guys help me please? i ve also formatted the whole pc: nothing

I followed the instructions that Eduardo from the Mozilla Support Team sent (see below) and I'm still unable to sign into Mozilla Connect.

"Before signing back into Mozilla Connect, I recommend refreshing your Firefox installation and clearing the cookies and cache for mozilla.org in order to eliminate any potentially faulty configuration files in Firefox, as these may also be causing the connection issue you're experiencing. You can also try opening a Private Window to access Connect."

I've re-linked my Mozilla account with my Google one but I still receive the 401 error when trying to access Mozilla Connect. I have also tried the disabling Windows Defender and Nord VPN & Threat Protection Pro.

I will note that I'm able to access Accounts and Support without issue.

I don't know what else I can do, this seems like I need someone from Mozilla to take action? ---

My original message:

> Whenever I try to access Mozilla Connect and Sign In, I am met with the following page: > > HTTP Status 401 – > type Status Report > Description http.401 > > I think this stems from me disconnecting and closing the account because it didn't register/sign-in through my Mozilla/Firefox account. I want to create a new one that is linked properly.

This happens when I click a link in an email or elsewhere. Firefox responds otherwise, I can open links within Firefox. It used to simply open the link in a new tab.

How can the previous behaviour be restored? so I can open a link in an existing FF window?

I have used Firefox for more years than I care to remember, but at the moment I'm forced to use Safari, which is OK but missing several vital features for me like translating Greek web pages!

The problem I have is this:- Whenever My M2 macbook Air running Sonoma 14.7.2 goes to sleep and wake it the screen is flickering and needs a hard restart. After lots of trial and error it appears to be something to do with Firefox version 133.0.3 (aarch64) as it only happens when I leave Firefox running.

I have run the Apple offline diagnostics multiple times immediately after the crash but I never get any reported errors. Interestingly I get no dialog from Apple that my Mac has crashed or needed to be restarted

I have restarted my Mac into safe mode, same problem

I have refreshed Firefox several times, same problem

Any help woulld be much appreciated!

Happy Christmas and a peaceful New Year to you all

Thank you, Peter

I have tried installing extensions on https://addons.mozilla.org. Everything else online works fine, but https://addons.mozilla.org gives me "Download failed. Please check your connection. " after 10 minutes of loading icon. Browsing works fine. I have tried with and without a VPN. It used to work. Other devices, and firefox on dualbooted linux work fine.
