Firefox Support Forum

No videos on any platform will play when I try to open them in Firefox. They are forever stuck on the thumbnail image of the video, and nothing happens when I hit play. I've had this happen a couple times and was able to resolve before by installing updates and uninstalling my Mozilla VPN, but this time nothing has worked. I've tried pretty much every solution I could find online:

• Updating Firefox
• Updating my computer
• Running in Incognito
• Running in troubleshooting mode
• Allowing autoplay
• Disabling hardware acceleration
• Disabling addons
• Clearing cache and data
• Enabling/disabling DRM content
• Installing Windows Media Pack

I'm running Windows 10, and videos seem to work fine in Edge, if that makes any difference.

I have been dealing with problems with Firefox and YouTube for a long time. Every time I open a YouTube video in a new tab it would always give me this grey screen that goes away after a long time waiting.

I have tried:

• Refreshing Firefox
• Reinstalling Firefox
• Troubleshoot Mode, which the problem persist in troubleshoot mode so its not an addon
• Tried creating a new profile
• User-Agent Switcher which doesn't work all the time.

I want to avoid going chromium-based browsers but this is making me consider.

Firefox is my favourite browser so I prefer using it in all my online activities. When I go to Adobe Firefly though, I consistently get a warning that this browser is not compatible and they suggest using Chrome, Safari or the latest version of Firefox !!! I am using the latest version available, 127.0.2 but Adobe does not detect it correctly. I have to switch to Chrome, that I'm not very fond of. I saw that a similar issue was posted 10 months ago but it's now archived and I can't even include a link to it here :( So, I hope this comment helps in case others have the same problem. I also hope Mozilla can fix the bug or whatever gets in the way. Lenovo laptop - Windows 10 updated Thanks!

Hello, when in the library, pressing F6 is meant to "Focus Search Field". This is documented at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

However, since a recent update this no longer works. Instead, pressing F6 now switches the keyboard focus to the lefthand tree pane. A further press of shift+tab is needed to move to the search box.

My questions are: Has F6 stopped jumping to the library search box for anyone else? If so, was this a deliberate design choice? Does anyone know of an alternate keyboard shortcut to jump to the searchbox? Finally, is there anyway to revert to the old F6 behaviour?

Even if you can only answer the first question that would help, so I can determine whether or not it is just my Firefox. Although I have already tested in a brand new profile with the same results.

Thanks.

I am deleting or updating accounts linked to an email that was hacked. However, I cannot make changes to this Firefox account that I no longer use because the email that was hacked no longer exists. I wish to delete the account because of suspicious activity. Thank you for your assistance.

I used to use chrome. There, when i add a bookmark, the title and the URL are prefilled. Which is very comfortable. Why is this not a feature in firefox? I always have to copy paste the URL and enter an own title. Chrome has become very slowly on some websites, while firefox does not slow down on those websites at all. So i want to stay with firefox. Good job, team. But the bookmarking UX is improveable.

On 18 June in the morning my bookmarks were all listed to the left of my browser and I shut down my laptop. That evening I turned on the laptop and bookmarks were gone the browser got brighter and my bookmarks are now only accessible thru a tab in upper right hand corner called other bookmarks. I want them back to the left side of my browser and do not know how to do it.

Hi,

Every time I attempt to login to YouTube or Google sites, this site pops up and I'm unable to log in using my personal account. I no longer work at this place and need it removed from my browser. https://launchpad.classlink.com/srcschools?chromebook=1

Thank you for your help in either removing it (if you can) or providing directions on how to remove it myself.

Thank you, again, Kay

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

Hello, I Signed into and began using a New Firefox ACCOUNT Yesterday.Today,I found that I had forgotten that I formerly had a Mozilla account which is apparently still ACTIVE from 10/14/2021. I'm confused as to WHY it's called MOZILLA... Is it called Firefox or Mozilla for this Browser... and I don't want two Accounts... so I need to eliminate one. My iMac is Auto inserting My Password and I'm not familiar yet with whatever Browser I have, to locate a way to see the Password it signed me in on... ? the one I created yesterday... or the one that was created in 2021... So.. please tell me what the Browser is called today... Firefox or Mozilla... or Mozilla Firefox... ??? and I'll begin AGAIN... OR CAN YOU FIX THIS FOR ME WITH JUST ONE ACCOUNT, and I'll create another Password. My email has NOT CHANGED for either account... ey47ey@yahoo.com Please advise me how to establish my Account ASAP so I can continue my work. I HOPE I can thank you in advance for clearing this up for me. I'm trying to "Run-Away" from Everything... Google!

Hi, I have been having this issue for a while. The search suggestions in the address bar are missing. I mean that the entire drop-down box never shows up. There are no search engine suggestions. There are no history based or bookmarks based suggestions.

The search suggestions is ticked in the settings. And I also disabled hardware acceleration.

Steps I took to troubleshoot: 1. Refreshed Firefox through troubleshoot mode. 2. Restarted firefox in add-ons disabled mode. 3. Tried creating new profile. 4. Tried using Firefox nightly and Dev builds. 5. Got fed up. Switched to Floorp. 6. I also tried a bunch of about:config modifications, that were suggested in earlier such support posts. None to any avail. 7. Tried it on an entirely different windows. And again, the minute I log in, the search suggestions are gone.

This is when I realized, the issue was popping up whenever I log in using my mozilla account. I tried any firefox alternative without logging in and the search suggestions work. The minute I log in with firefox account/mozilla account. The search suggestions stop. This has to be something due to sync is what I guessed. And I stopped sync. And reinstalled. Then the issue resolved. But the minute I log in it reverts back. And no search suggestions.

The search suggestions do not work on any windows based system. I checked my android device and suggestions are working. Sadly, I do not have access to any other platform.

So at this point I was very much frustrated. So someone please help me out. I will give whatever logs you need. But fix this. I need search suggestions. At least bookmarks and history. I believe it to be a core part of the experience.

Not even recently searched are in suggestions. That drop-down box itself is missing.

The address wasn’t understood Firefox doesn’t know how to open this address, because one of the following protocols (javascript) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address.

Im getting this message on my newspaper site. It will not let me open the whole page just one article at a time but only after clicking above message

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.

Out of nowhere a couple days ago Firefox started loading local html files extremely slowly. I was using Live Server to render the pages, so I turned that on and off, uninstalled and reinstalled to no avail. I tried dragging files in from the original folder on my computer, but even that doesn't work. I tried updating firefox, and then my computer (which is running Fedora Linux 40), but still nothing.

When I try hitting inspect on the page, it only loads the HTML but doesn't let me inspect the JS as it wont load, and it's saying I have a ton of errors too. I can't look at the errors because they wont load, but I know it doesn't have to do with the original file as there was only one error which the page was working fine with before and each time I try opening the file it gives me a different amount of errors.

I tried clearing my cache and cookies, which didn't work either.

Does anyone know how to fix this? I'm having no other errors on other pages.

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

Hello, My website www.bodymindwholeness.com will not loan on Mozilla browser for over 6 months now. My website loads just fine on all other browsers, just not Mozilla? I have tried to adjust every setting I can imagine with no luck. Why wont Mozilla allow my website to load and what can I do to fix the issue? Thank you Michael Hofrath

Hi Firefox team

I am Yuki belong to Electronic company IT department. We have a project to implement salesforce for customer facing and target to go live by end of this July. we are facing one issue related with firefox and salesforce.

<issue detail> Our salesforce have customized serach founctions. this search function doesn't work only in firefox browser(Edge, Chorme is ok). we can send input data from salesforce to search, however search result doesn't appear.

<current situation> we were investigating this issue with salesforce. we found this article : https://developer.salesforce.com/docs/platform/lwc/guide/security-lwsec-async.html >When LWS is enabled, JavaScript async functions that are used from a static resource work in Chromium-based browsers, but don't work in Firefox currently. The issue is a bug in Firefox.

<requet to firefox team> Would you solve above bug?

if yes, I would like to know the timeline
if no, I would like to know the reason why you don't solve.

I want to print a Firefox PDF document. It is a credit card statement downloaded off the issuer's website. The PDF file Properties dialog shows Page Size 6.92 x 14 in (Portrait). The thumbnail preview of the document shows the pages in the 6.92 x 14" format. I want to print this document to 8.5 x 11" paper WITHOUT HAVING THE DOCUMENT SHRUNK TO FIT THE SMALLER PAPER. Shrinking the document results in a printout that I cannot read without a magnifier. This is unacceptable. I don't care if the bottom 3" of each page are cut off (mostly that 3" is blank anyway). All I want is to be able to print out a document I can read. NOTE: I have tried using the print dialog option "Size to [choose % magnification]," instead of "fit to page width." This does not work. The print image stubbornly refuses to magnify, the print preview still shows a legal sized document crammed into letter sized paper, and I'm still stuck with a shrunken document with teeny tiny text that I can't read. NOTE: I have also explored using the "simplified" print setting instead of "original." All that gives me is a text explanation and the original document itself disappears. So no joy there either.

Firefox 127.0.2 (64 bit), Windows 11.

Suggestions?
