Diễn đàn hỗ trợ Firefox

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....

Since the last update (136.0.4 (64bit)) firefox only partially shows an embedded google spreadsheet. It was fine in the previous version. Tried turning off enhanced tracking protection, but that didn't do anything.

Firefox just keeps getting slower and less responsive. I've cleared the history etc and run my Avast cleanup premium which helped a little, but the other browsers just put it to shame. I hate to switch because I love the user interface, but............ its just frustrating. Windows 11 latest updates.

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

On May 1st, when I launched Firefox(afternoon some time on US East coast) it ran an update to 138.0.1. When it was done, it did not launch. So I clicked the icon on my desktop and it came up, but then closed out after about 15 seconds. When I reopened it, it asked to continue in troubleshooting mode or refresh. I tried both. No luck. I restarted and even uninstall and reinstalled the latest version as well as tried installing 137.

I have tried with virus/malware protection/firewall off. I have restarted. My page file is default. I tried renaming the firefox.exe to something else. I tried creating an new firefox profile(firefox.exe -p) but that crashes too.

I installed the latest version of Firefox Nightly and it stays open just fine. But when I launch the regular firefox, they both close.

I also installed the Firefox app from the Windows store and it behaves the same as the one from the mozilla website.

Good day

Firefox was working fine till yesterday. No changes of any kind were made.

Firefox will no longer play any audio.

Audio plays just fine from every other browser and Windows test.

I have attempted and followed many variations of suggestions and still no sound. Been through permissions.

Any one have a silver bullet to get audio back?

Thanks

cannot open allmusic.com website anymore on firefox. this website opens fine on other browsers. Only Firefox is the problem. Any suggestions?

My Firefox Browser keeps crashing at random times. I was using Chrome previously and it was worse than the Firefox performance. I just installed 128 GB of brand new DDR5 RAM which I tested in windows with no error. I have no malware on my computer currently. I ran all of the usual checks that you suggested with regard to extensions and cache. Here is the most recent report ID that was generated by Firefox:

bp-7c5d5dcf-2fc9-40a3-9659-ff55f0250424

Firefox (current version:137.0.2 64-bit) does not allow drag from outlook on the web and drop on windows 11 file explorer. It shows a forbidden sign when i am dropping on file explorer.

How this problem can be solved?

Sat. 04/19/2025 @9:10 am CDT - Hi. About 2 months ago on any Settings page, FF began to show "your browser is being managed by your organization." The problem is - it's a STANDALONE box, not connected to any network beyond my ISP. I do own websites but I'm not perpetually logged into the host company, so their switch to Microsoft Entra wouldn't have an effect, I would think.

What settings do I change to make FF know that I'm not on a network? Thanks in advance.

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

I have a Dropbox Paper document that I use for my bookmarks. It lists the name of the site (with link attached) and hints as to my username/password for any given site I use.

For years, it has worked just fine, but trying to solve a different problem, something happened (in my settings?) that renders those hyperlinks non-working. When I click on, say Facebook, it formerly took me right to FB. NOW it gives me a weird yellow box in the upper right corner that says "about:blank" in the upper left of the box, and 3 white boxes at the lower right of the yellow box "Allow" "Deny" "Close." If I click on "Allow," I get a blank page. My navigation doesn't seem to recognize the links I've placed in the Doc.

A friend on FB posted a link to a YouTube video and when I clicked on that, I got the yellow box with the proper URL and a white box option to continue. I've tried to recreate that particular box, but, apparently, once it's accepted, it's OK from there on out.

I have tried deleting the link from the Paper Doc and reinstating it, and I still get the yellow box.

What have I done and how the heck do I get rid of that yellow box?

Yesterday my audio on Firefox worked, today it doesn't. I tried all the regular trouble shooting solutions. - My system volume is not 0 - My tabs aren't muted - My headphones are turned on and working fine (audio works everywhere but Firefox) - I uninstalled and reinstalled my Firefox - I uninstalled and reinstalled my headphone audio drivers - Audio also does not work in a private browser, so I know the issue it's related to extensions, cookies, etc. - I had Windows 11 do a quick diagnostic, so the issue isn't Windows 11 related

Usually when this issue occurs, it's as simple as switching from "default" to a specific speaker in volume mixer, but Firefox is not appearing in volume mixer like it did in the past, as shown in the screenshot below.

I don't know what else to do at this point. In previous documentation here, the solution for some people was to wait and it eventually fixed itself, but I'd rather not have audio for weeks to months on end, so has anyone found another solution by chance?

Having issues with my Bluetooth AirPods and sound in Firefox. The problem being there is no sound when the device is connected and watching a YouTube video for instance. Things went wonky after the recent update to 133.0.3. At first there was no sound period. Then somehow, not even sure how, I saw that Firefox was muted in Windows (11 Pro) settings. That's a mystery unto itself since I'd never previously gone to that area. Now that I have volume through external speakers working, audio through AirPods doesn't. Everything works fine using Edge and audio from music. I know the device is connected and when that is, it's the default for where sound comes from. Used the test thing and yup there is audio. Is there something I'm missing? There must be but I can't figure out what it is. Hopefully someone reading this can point me in the right direction of resolving this issue. Thank you in advance.

Hey all, I'm hoping someone can help me. I have found no answers online to date.

I cannot print from the Firefox browser. When I click the print button, my printer spits out a blank page.

I can print from any other browser, Word, Excel, PDF files, anything except for Firefox. This may not be as much of an issue if Firefox wasn't my primary browser, so when I start doing work on it and find I need to print something at the end, it's a problem.

My printer software is up-to-date, I tried resetting the printing preference to default (assuming I did this correctly), and I even uninstalled and re-installed Firefox (which was a disaster). None of this helped.

Is there one of you who may be able to provide me with the help I need?

I appreciate your effort greatly.

I am trying to install firefox on my new work laptop. The OS is Windows 11 Pro. It came with an ARM CPU. Specifically: Snapdragon(R) X Elite - X1E80100 - Qualcomm(R) Oryon(TM) CPU. Everytime I try and install Firefox, which is probably over 10 tries by now, it fails with generic errors. I have tried cleaning everything Firefox related off the PC before subsequent attempts and still get the same errors. I am including a screenshot of what I see shortly after starting the install process.
