Diễn đàn hỗ trợ Firefox

I'm on a Mac using Mac OS Big Sur, 11.7.10.

Videos will not play on Firefox, whether on Youtube, in social media, on websites, or whatever. Sometimes the video will play with no audio, sometimes I just getting a rolling wheel.

I have other functionality issues that may be related.

I don't want to close and restart all the time. I am considering changing to a new default browser over the issue.

If I switch to Chrome or Safari, the videos play fine. Which seems like my answer.

Recover data from previous version of fire fox and help with the new version

I can be reached at [edited phone# and emails from public community support forum] or [edited] or [edited] I have used both emails in the past. In general I have not had a very good experience with this new version!! Can someone please help me!

Thanks James Webb

Hello. i noticed that my shortcuts are missing. i went to settings to check if it's enabled (check mark) and it is in fact enabled. tried to reset my computer and the shortcuts are still not there. on the main firefox page there is actually no shortcut icons on there...at all. all of the options in settings work with the exception (of course) the shortcuts. i would like to know why this is happening...thx

I tried logging into my account on a website. I decided to click on the passkey option to log in. Firefox had ask to access my passkeys and I mistakenly declined. But the pop-up doesn't happen again. It goes straight to "authentication failed" without trying to ask me again to access the passkeys. I don't see any setting for this in the settings page.

How do I change the permission to let Firefox access my passkeys? Or how do I make Firefox and Windows ask for my permission again?u I'd like to not have to reinstall Firefox if I could.

How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

I have a local file I wish to view in firefox without starting a HTTP server (it's only docs for a crate I'm building) however Firefox is unable to open the file despite the file existing and having correct permissions. The file was in a separate mount (disk) to where Ffox is installed so I copied to to /tmp/ to remove that as a variable but still no joy..

➜ ~ file /tmp/index.html /tmp/index.html: HTML document, Unicode text, UTF-8 text, with very long lines (3556) ➜ ~ ls -la /tmp/index.html -rwxr-xr-x 1 ben ben 4208 Dec 30 14:04 /tmp/index.html

Am I missing some new setting which allows local file browsing using the good old 'file:///' protocol?

Thanks, Ben

For the last few days, Firefox is being removed from my computer overnight and i have to re-intall the browser the next morning. Sometimes it's still there the next day, and sometimes it's gone again the next day. What i causing this and how can i prevent it from being removed? Jenny

when I try to log into my gmail account, it is asking me to verify by log in first to an inactive account that was linked to my gmail account. with Chrome I have no problem log in to my gmail account

Is it possible to click individual segments of an URL in the address bar to navigate there directly (without manually selecting and deleting the tail)? It's a convenient way to reach upper layers of a website.

For example Vivaldi implements it via Ctrl+<Mouseover/click> (see attached screen capture)

Is there an option or addon to enable this? Thanks in advance

(In reference to [post] where it said "This thread was archived. Please ask a new question if you need help.")

O, woe, I feel like Jacob Marley wailing in torment, ha! My correctly-set selection of "Always ask you where to save files" still does not function in 146.0 on Windows 10 after I have gone through every permutation of settings, updates, restarts, etc., I can think of. Why does it always every time only automatically download to the download "Save files to" location (which one MUST set with no option to not set a download location). I have even selected "Ask whether to open or save files" on the "What should Firefox do with other files?" section. I want to be asked each time where to download just like Firefox used to allow and still falsely promises. Am I doing something wrong, or is it a vast Left Wing conspiracy with which Firefox is colluding to oppress people who want choice over their lives like me? :-)

I was sent an email so I could reset my password, and Firefox said I was using windows 10, when in fact I'm using windows 11, unfortunately. Is this a bug? What gives?

I read article at: [https://support.mozilla.org/en-US/kb/.../firefox-backup?as=u&utm_source=inproduct#w_create-a-firefox-backup-file]

But in my up-to-date (or updated) FireFox, the restore backup by file option is appearing BUT enable backup or backup to file option is NOT appearing (screenshot attached).

I abhor the use of AI in the one browser I use because I thought it was far safer than any other browser. I have switched to Firefox because I knew it hadn't tracked my data, nor did it shove useless and unwanted features onto me without the ability to tell it no. But apparently, that has changed.

The blatant disregard for any opinion other than the CEO's in terms of including the implementation of AI tells me that Mozilla has little care for what their users want. Many people are speaking out against AI, many people here on these forums especially, and I am adding my own voice to the choir.

If the use of AI features continue to be added, I will consider simply switching browsers to one where I can at the very least patch out the AI entirely. I will be taking me, and my funding, with me, and I will not be looking back. I would hope these rising voices will be heard, and taken into consideration, before Firefox all but goes up in blazes and never reignites again.

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.
