I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

I've imported bookmarks to Firefox, however the Bookmarks bar doesn't show on a blank tab (I'll raise another forum post about this). If I manually add the Bookmarks toolbar, it permanently shows only a few Bookmarks, not the original Bookmarks that have been imported?

I imported the Bookmarks 3 times as shown on the attached screenshot, but somehow they have been stored by default, in the wrong location. The correct location would be so the Bookmarks appear in the Bookmarks toolbar.

Today I've noticed some horizontal lines on youtube videos. Upon further investigation, I've traced it to a single div element:

The base64 encoded image is the lines I'm seeing.

Initially after starting a new private session and navigating straight to youtube.com I had no lines. Then in that private session same element doesn't have an image:

What's odd about this is if I opened a private window and copy pasted the same video URL I would get the lines. After testing multiple times I started getting the lines even after navigating straight to youtube.com.

So I did another test: changed my IP with a VPN in a private session. Navigated straight to youtube.com, watched multiple videos without any lines. Then I logged in to my account and boom, the lines are back...

Opening the same video on google chrome browser I get a smooth gradient line image:

The browser is functioning as intended, but youtube is intentionally making their website unusable. What the f###? I have youtube premium, adblocker disabled on their website.

I had two profiles, was in the process of trying to learn how to use the 2nd profile (as seen in the link below), which I still have no answer for. Somehow, maybe I held down SHIFT for too long and clicked on something by accident, idk, but somehow, I ended up REFRESHING the 2nd profile, causing it to delete everything I had done with it, and it backed up the old profile onto my desktop in the process. I figured I could just simply delete the new profile folder it had created and put back my old profile in the profile folder, but now, Firefox will not open at all, saying "Your Firefox profile cannot be loaded. It may be missing or inaccessible." How do I get it to recognize the profile folders again? OMG, I'm using Microsoft Edge, please, get me out of this!

I have just got a new laptop and installed everything in relation to Firefox onto it. I have used the Nordpass extension for a couple of years and on the old laptop this is version 5.23.13 updated 16/10/24. On visiting the add-on and extension site today there is only a legacy version 4.33 updated 2y ago which clearly no longer works. Where has it gone. Clearly I am going to ask the same question of Nord, but I hope you can help.

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

For the past week now, every time I go to this link https://marketplace.secondlife.com/ , it is in another language. Usually Spanish or Portuguese and now and then French. I'm always having to translate. Even though my settings says English and i have no other options.

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?

Thanks,

DC

I have forgotten the purpose of the green outline around the page's border. What does it do and how to turn on, after turning it off. Thanks in advance. Let me know if this is an extension or some other feature. Thanks, JJE

I have been setting up Passkeys to log in to the websites which allow them. But I have noticed on Paypal, they do not allow me to use passkey when using firefox, it only seems to allow chrome

Is there an issue with firefox which deems it not suitable for passkeys?

I noticed that sopmeone asked this question this time last year and it was advised that firefox is now able to create and store passkeys Paypal still dont seem to allow it?

Since April 5th I have lost spell check in the message pane of the emails I type on outlook.live.com It still works in the subject line, but not the message area.

Windows 10 pro 22H2 updated to end of March, when spell check was still working well. Firefox 137.1 English Canada Language selected (has worked well for years)

I go to outlook.live.com to read and answer my @hotmail.com emails.

When right clicking on a misspelled word in the message area I get only these options, Firefox does not give me the usual options.

I am currently having other problems on that site, clearing outlook.live.com cookies does not clear the problems.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

Why are these showing up now? They were never there before. Is there a way to hide them or make them disappear? They are ugly, distracting to look at and unnecessary. I tried one about:config solution, but it did not work. Please fix this. See screenshot. The black tacks should not be visible, but now they are.

Running Win11 on desktop PC. Sync option offers QR code to scan but Firefox on android does not have sync scan option on settings. Despite instructions to contrary, that option is not listed on mobile. Yes I'm logged in and yes I have synced previous versions of firefox

I get a different UI when I open NotebookLM from google. My pixel tablet uses Chrome and it loads with the standard 3 panels but in Firefox I only get one screen. Everything else works in the program.

When using Google Meet in Firefox browser, I am only able to share my window, not my screen. When I choose "share screen", it says I must change my permissions - but my permissions settings have not changed and this is a problem I have started having only in the last few days.

I do not know where I am supposed to change these permissions settings.

I have checked my permissions in settings > privacy & security > permissions - there is nothing there about screen sharing.

I have checked my permissions in padlock > connection > more information > permissions and the only options I have for screen sharing are "always ask" (default), which is set. The only other option I have is "block" which is not set.

My Firefox browser is up-to-date.

Can anyone help? Thanks!

Bookmarks have been intermittently disappearing for weeks but I could always see the blue star when I visited favorite sites that I use upon starting my day that I had bookmarked. This morning all bookmarks were missing. I tried clearing cache which had worked to restore some bookmarks that were missing. Now everything is gone and I cannot recover them. There is an error that appears when I open Firefox re: bookmarks and I followed the steps but it did not work. I really need my bookmarks to do all the things I need to do, like everyone else, including medical information websites. I hope you all can get this figured out as it has been a problem for a month for me, on a PC. I know my favorites are stored somewhere on this computer but I cannot make them populate. If someone would like to take control of my computer and fix it for me, I would happy to let you do that. I have run sfc/scannow and chkdsk/f as well as a total virus scan with Norton. I have restarted my computer several times as well as done a complete shutdown several times.

I'm on Firefox mobile, and I keep having this issue, and trust me, I've searched for solutions, but they just haven't worked out. Wverytime I open the Firefox app, it asks me to "get started". I've had Firefox for nearly a year now and it's my default browser. The only thing I can think that could be causing this issue would be me recently syncing my account onto my computer, but that was a little while ago and it used to not do this every time. Now it is. Please help?
