I have seen multiple copies of this question, some unanswered, some with the same "answer". All the questions are closed so I cannot reply to them. The "answer" does not work.

I have the "Show tabs from other devices" sidebar. I also can access from "Open application menu" > email address > list of synced tabs. Both methods show me the device name and all of my synced tabs. Neither method has an "open all tabs" option. If I right click my device name nothing happens. If I right click a tab, it opens that one tab. I don't know how many tabs I have on my Android. I have enough tabs that it only shows the infinity symbol instead of the number. It has shown the infinity symbol for a long time and I've opened many more tabs since. It could be hundreds or even thousands of tabs. I have 224 tabs on my laptop. I want to open all 224 laptop tabs plus all however many Android tabs on my laptop at the same time. I'm aware this will cause significant lag on my laptop. I'm not looking for a solution for that or people telling me not to do that. I want to know how to open all of my synced tabs at once on my laptop, without having to click through one by one.

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

I've just had to completely reinstall windows without being able to backup my files (I couldn't launch my computer in order to actually back them up) meaning I've lost my recovery codes. I thought this would be fine as I could just sign back into firefox on this new install of Windows but as it turns out I must've forgotten to put my sign in information into my password manager. Again, I thought this would be okay as I still have access to the email I used to sign up to my firefox sync but I got the message saying I'd lose my data which isn't fine and now I'm at a bit of a loss. I've had to use a spare email to make an account and ask here but I'd really love my old account back. Is there any way at all I can get back into my account without losing my bookmarks and passwords? If not, how much information would I end up actually losing? I'm slightly unclear on that part. Do I lose absolutely everything? I'm a bit stressed about all of this ontop of losing all of my old computer files so I'm sorry if this is a commonly asked question but I was struggling to find anything that helped me D:

Any advice at all would be really appreciated thank you so much!!

Firefox opens with a new tab containing 8 links per row. However, all subsequent new tabs have only 6 links per row. They used to always have 8 links per row. Why? A bug or a configuration change? I have made no changes.

Hello all,

I am having problems with video playback on some websites (see screenshot attached). The problem is that the video options start to "multiply" - for example, when I start the video there is (as is normal) one 'Speed' and one 'Quality' button, but then every second these buttons start to multiply. This happens only on some websites - for example, it does not happen with normal videos on YouTube, although it happens on YouTube Shorts sometimes.

This is my first question on the Mozilla Support page, I thank you in advance for your help and I hope I follow the community guidelines. Please feel free to leave any suggestions or feedback concerning how I should proceed for asking for help in the future.

i cant move the tabs around in the task bar. my firefox version is up to date, but yesterday-ish my laptop forcibly updated itself. its still on windows ten, but thats the only thing i can think of other than installing a kidpix four emulator that may have caused the problem

When I type about.config in the address bar, I just see search results for it, instead of going to the config page. I tried enabling a separate search bar in settings, and also turned off all suggestions, but that did not help. I still see the spyglass search icon on the address bar. How do I get past it?

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

I have adblocker plus and is not blocking my facebook ads. (I am using it on my iMac). So I removed it, then reinstalled it and it still does not block the facebook ads.

I tried refreshing firefox 3 times but it got stuck in the "almost done" part and I had to quit firefox each time since it would not complete the process.

What else can I do?

Thanks, Martha

Since the last Firefox update (I'm now using Firefox 113.0.1 64bit on Windows 11) when I play a video on Twitter, it plays with the right colors until I fullscreen it. When I fullscreen it, the video becomes darker and the colors are wrong.

• The same happens to youtube videos (both fullscreen or normal size): the colors are not right and they looks darker.
• The same problem happens using both my laptop's internal monitor and the external monitor.
• I tried to reinstall Firefox but it didn't fix it.
• I also tried to take a screenshot of the "wrong colors" videos using the Windows screenshot tool but the output image is displayed with the right colors and not with the darker ones.
• Using Chrome the colors are correct and I never had this problem before the last Firefox update.

When FF (113.0.1) is maximized clicking on the first (left hand) pinned tab does not open the tab. Hovering over the tab doesn't change the background color of the tab.

If I restore down the window, hovering over the tab changes the background color of the tab from light grey to a slightly darker grey and clicking the tab opens it.

hello i have around 30+ themes and i want to delete all of themes (because i want to keep the favorite ones ) but if i delete them one by one takes time , is there any option to delete them all at once i haven't found anything on internet

When I right click a tab I do not get the option to "Send Tab to Device" that I am used to on Windows. Is this missing from the Linux version? Or is there a setting for it?

I have searched the internet for this problem and could not find such things. I would appreciate any help!

Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

We have set up exceptions for mail.google.com and accounts.google.com in Settings. Yet, Gmail is still asking for passwords to log in and saving them. I thought I had done all it would take to have Gmail remember them. Am I missing something?

Also, we cleared cache.

Thank you, Meg

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Just recently, in the past day or so, when I do a search in the search box, all the results get redirected to Bing instead of Google, that I have in my settings as default. I have checked my settings, I even removed Bing from the list, and I still only get Bing results. Even when I go to Google and use their search box on their domain, I get Bing results. I did a virus scan without finding any problems. I'm stumped and don't understand why this happened and nothing I do can detect uncovers why this is happening.

Really irritating when I have to spend my time fixing stuff that is lurking in cyberspace!

Hey there,

I have been using the arrow keys to scroll pages more and more often and was wondering if there is a way to increase / decrease the speed when holding down the arrow keys to scroll the page?

Thanks in advance. :)
