I cannot pin the extension to the toolbar. The extension is not shown in the puzzle icon dropdown, and it is not in the overflow. Please add an automatic pin to the toolbar when a new extension is added! How do I pin it now?

I can't upload videos to YouTube via Firefox. Uploading progress stays on 0%. Using the Edge browser videos upload normally. It has always worked with Firefox previously.

It is really very strange and unbelievable! No page is open, but the memory occupies more than 700 MB and uses more than 20% cpu! What should I do exactly? I use Windows 11 24 H2

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!

Ever since a few weeks ago, some of my add-ons as well as every new add-on I added after that are unavailable at the start of Firefox. I then have to click into the application menu, click on the warning message for that add-on and enable it again. Since this is quite tedious and frustrating, I tried looking online for any info. I tried updating everything, disabling and enabling manually and removed and re-added some if the add-ons that cause issues.

I am loath to set up a fresh profile or reset all add-ons as that would cost a lot of time to configure everything again. In hopes of a solution that avoids that I am asking here now.

I am running Firefox 132.0.2 on Pop_OS, using Gnome. I have a dual monitor setup, with my leftmost monitor being a 1080p set as portrait, and my main being a 4K set as landscape.

Every time I open Firefox, the window is exactly 1080 pixels large, no matter what I do. I can of course resize it, but it's frustrating having to do that every time.

If I tell Gnome that my secondary monitor is on the RIGHT side of my primary, everything works perfectly: Firefox stays the size it is when I close it.

It seems that Firefox uses my leftmost monitor's size to determine the maximum windows width, and even overwrites my xulsettings.json every time I close it.

I tried different builds, and even different forks suck as librewolf: no difference. I can´t of course change the position of how my monitors are placed on my desk.

Any ideas?

Hello! My download settings are (and have always been): always ask where to download files (in all options). In the latest versions, Firefox automatically opens downloads in a new tab without asking and downloads them to the default folder. This is an inconvenience for me. Thank you for your attention

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?

Firefox won't load videos that other browsers will. Typically, when I load a page, there's a big blank spot where the embedded video should be -- where the video shows up on Chrome or Safari. I've tried clear the cashes and reloading Firefox, but the problem persists. For many reasons, I'd prefer to use Firefox, but if I can't fix this, I'll stop using it at all. Can anybody suggest ways to fix this?

Is there a way to block pop-ups on Meredith Dotdash websites, e,g. seriouseats.com, foodandwine.com, etc. Please see attachments

I don't know what's happening but since a couple of days, let's say Wednesday 13th November, my firefox got incredibly slow: everytime I insert a url or a link in the address bar and press enter it takes a lot of time to completely load the website.

I tried to use Edge instead, and Edge is working flawlessly, while Firefox is not.

I also did a fresh install, wiping the %APPDATA% folders too, but nothing changes.

Setup:

• Firefox version 132.0.2
• on Windows 10
• Firefox and Windows are 64 bit

Firefox is a browser but not a search engine correct me if I'm wrong. Also now when typing in the search box down by the start button searches come up but I cannot get links to open when I click on them and even if I right click on them nothing happens

Firefox history contains youtube videos I didn't watch (and that aren't in my google youtube history). I've realised they go back May, roughly when I got my new linux machine and installed Firefox. However, they also seem to have been watched outside the time any of my devices apart from my phone are on. They're mostly just junk videos about minecraft etc.

See attached pic - the ones this morning between 5.48 and 7am I didn't have the laptop turned on. My phone was on though, but by the bed.

How has this happened and how can I track down how to stop it?

I'm writing this on my Windows desktop, can send details of other devices if useful.

Firefox does not seem to be properly configured for Wayland on KDE Plasma 6.x systems. The generic "Wayland" logo appears in task switcher instead of the Firefox logo. Firefox is the only program I have with this issue. Setting desktop name (org.mozilla.firefox) as a property in the Window and Application Manager settings does not resolve the issue.

I have a problem on the aliexpress website. (in other browsers everything works fine) When I open tabs with goods on aliexpress. and start switching between them, then at the moment of switching to another tab, my previous tab itself is updated and opens the main page. And there is no way to even press the “Back” button. The browser seems to reload the page completely. The chatgpt was unable to find a solution. All hope is on you. There are no errors. It's just that the aliexpress page reloads by itself when I switch to any other tab.

Firefox was crashing so I found the folder in C:Program Files and renamed it before a new install. I downloaded the new Installer and installed Firefox again thinking all would be saved, but now, my bookmarks are missing and the history from the last few weeks are gone and started with the date I re-installed it. I have an old AT&T email that is now Yahoo and been using it for years. I tried to log in and I get a different screen asking about an ID which I don't have. Firefox always launched showing this icon to start yahoo as well as Chase Ect...ect and all are gone.

Is there a way to point to the old folder, after changing it back to original name and get back to previous version?

I did find another Mozilla file under Users,ComputerName,AppData, Local. I don't know if it was created with the new install or there before and just updated because I renamed the first file I found and now it's using C:Users to start Firefox. Any help getting back to where I was is appreciated.

Thank you

Tony
