Firefox Community Forum

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:

Device name LAPTOP-AI6N0TEJ Processor 12th Gen Intel(R) Core(TM) i3-1215U (1.20 GHz) Installed RAM 40.0 GB (39.7 GB usable) Device ID BDD80B46-B5E1-4B25-9FA0-3F833BD30C05 Product ID 00356-07436-33870-AAOEM System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display Edition Windows 11 Home Version 25H2 Installed on ‎11/‎7/‎2025 OS build 26200.7840 Serial number PF4RQKQJ Experience Windows Feature Experience Pack 1000.26100.291.0 Manufacturer Lenovo

On my first PC, I have this specific sidebar icon in my toolbar. When I click it, the sidebar opens with Gemini ready to go. Perfect.

But on my second PC, that specific icon is nowhere to be found. Even when I go to "Customize Toolbar," it’s not in the list of available buttons. The only thing I can use is the generic "Sidebar" button, which is annoying because it doesn't open Gemini directly, it just opens the general sidebar and I have to click again.

I provided an image, where the first icon is what I want, but only second icon is available.

thanks for looking into.

Just recently when logged onto Hotcopper.com.au have been getting a message that reads "This page is slowing Firefox down. To speed up this browser, stop this page." There is a STOP button, that helps for a moment or two only. When I open the program with MS Edge, the problem does nor occur. I was going to remove the Firefox App but saw the repair option. Repairing did not stop the problem. Any suggestions? John I have a near new Acer laptop running Win 11.

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

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?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

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
