Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

thanks for looking into.

Is there anyway in the setting to stop a shortcut from being added every time I visit a site? I only want sortcuts that I use. I have attached a screenshot circling the ones that keep popping up as an example.

Respectfully, Rhonda

just installed thunderbird on my new windows11 laptop and tried to add my comcast email account. i entered the email address and password and it sent me to a comcast web page to validate my email on imap.comcast.com. i am not on my home network so they sent a code to my phone which i entered successfully. it then asked for the address on my (comcast) account. i entered it and it told me it didn't recognize the address. I called comcast and finally got a human to talk with. we verified that my comcast account was set to allow third party access to my email. that's all the help she could give. i've run thunderbird on my windows 10 desktop with my comcast email for years with no problem. Has anyone encountered this problem?

I have 18 shortcuts that I have added to the Firefox desktop, but every time I open a new link, a shortcut is added to the desktop. How do I keep these unwanted shortcuts from being added to my Firefox desktop?

I have left Shortcuts toggled on, since I want to see the 18 shortcuts that I have manually pinned. Fine so far.

I have unchecked Sponsored Shortcuts, but I still am seeing sponsored shortcuts. What am I doing wrong?

Sometimes, I cannot click on an option on a form (on my up-to-date Firefox, on Windows 11 - help, please! Its usually only when the options are shown as little buttons or squares to tick off. Its not my mouse because it works for the usual mouse works.

I can't enter the tick/click necessary on this form to say "Email me when someone answers this thread" Cheers, Carol

Due to an internet outage, I got forcibly signed out of my Firefox account. I signed back in, but all my login info and passwords are just gone. I still have my browser history, and I'm even still logged in to some of my accounts, so I know some of my cookies and cache are intact.

I am using Firefox on Windows 11, in the process of switching from Chrome.

I run Cockpit (https://cockpit-project.org/) on web servers that I manage, and when I log into it on Firefox the screen flickers constantly, making it unusable.

There is no issue with any other web sites I have visited, and I can still use Cockpit when in Chrome. So ay suggestions on how to troubleshoot and resolve the issue with Cockpit and Firefox?

Bonjour,

depuis le début de la semaine lorsque j'ouvre firefox mes marques pages de ma barre personnelle sont disparu et ne sont pas non plus dans l'historique de récupération. il faut que je "répare firefox" pour qu'ils reviennent. mais le problème revient. parfois plusieurs fois par jour. Je n'ai jamais rencontré ce problème auparavant. J'ai un message de firefox qui m'indique que firefox est ouvert ailleurs. mais je ne sai pas où. merci de bien vouloir m'indiquer ce que je dois faire

господа,здравствуйте,помогите пожалуйста,любое видео разворачиваю на полный экран на мониторе HDR,а оно тусклое,никак не могу победить эту проблему,я бы отказался от всех остальные браузеров,но вот это единственное что меня останавливает

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

BT yesterday misspelt my email address with an additional 'h'. Although the original address has now been restored, firefox will no longer accept the original version (displaking a red sticker saying 'email address or user name misspelt') and I can only read my emails using on my Windows laptop using Microsoft Chrome. As I dislike having anything to do with google, please can someone explain how to resolve this problem (by removing cookies or whatever else).

Many thanks,

Oliver Crichton
