Diễn đàn hỗ trợ Firefox

Hello. For a while now I have been using the picture-in-picture feature to play a video in the corner while using other applications. It has been a great help as I have a single monitor.

Unfortunately, I have recently been encountering a severe issue with the feature over the last week. When attempting to use picture-in-picture while my computer is running a videogame (through Steam) my entire system will freeze. The audio still plays as normal, but the image is frozen and the system is unresponsive until I force a shutdown and reboot.

Any help at all in with this issue would be greatly appreciated, thank you.

I recently downloaded Firefox and would like to use it as my primary web browser (M1 14" Macbook Pro). But my Google calendar web site is not showing any colors, making it hard to use. On my other browsers (Brave, Safari, Edge) it works fine . See screen shots below from Firefox, Safari, Brave. I have tried re-booting Firefox, the computer, reverting the Firefox theme back to basics etc., and searching on line for a solution, but I can't find anything. So far all other websites are working OK, except for 1 other that has partially the same problem. If it can't be fixed I'll stop using Firefox, which I otherwise like.

Thanks for any help.

Maybe after update, or i dont know why, but now. when youtube (or any other videoplayer) in fullscreen - taskbar menu is visible (Is on topscreen). In google chrome problem is not repeats. I'm using StartAllBack app for classic start menu, but till that day all was fine. I checked on two devices with firefox - the same problem (StartAllBack or windows version wasnt cahnged). Windows 11 24H2

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Mac OS Sequoia 15.5 Firefox 138.04

I have notice for some time the Firefox start have updates almost daily it is not too bad whats that bug me is the matter the updates only start show up the information the availability after you log in any account or web site , never in your Firefox Home. you can stay 1 hour with Firefox open with home screen and no alert of updated show 10 second after you login in on email account or enter in any web site the pop up the availability updated what start became annoying .

Thank you .

Most other forums don't impose this type of limited categorization. What is the best way to proceed here when you topic here doesn't have an obvious fit? This is not uncommon. Should I be concerned that my question won't get to the right eyes/assistance needed?

Some venues offer the ability to add tags. Why not give us the ability to add "tags" if you believe some sort of pre-designation is necessary? Does that qualify for my choosing this topic?

How about "other"?

To the right of Other Bookmarks Firefox still says "finish Setup" but I've checked everything and run the setup. I can't seem to do anything to correct/clean up this?

Thank you.

Suddenly today (April 30) when I try to go to Yoube home page, I get a blank (see the picture). But if I try in a private window, it works.

I see Youtube has re-designed its home page - maybe that's part of ther problem.

Is there a setting I can change?

Here is something I have never ran into, for some reason suddenly today, I am only able to load about half the websites I try to load. A blank page loads that says "Hmm we're having trouble finding that site". But the tab says "Server not found". Again it's only some pages that won't load.

It does not matter if I click the bookmark, or type in the address,it's always the same pages every time. I tried 19 sites, (10 bookmarks, and 9 typed), plus typing in some of the bookmarks also.

If I change over to Chrome, or any other browser those pages will load. If I use Firefox Mobile, those pages load. Something has gotten messed up in my PC settings, or something.

I have tried clearing the cache, the history, and the cookies, no luck. I restarted into safe mode, and had the same problem.

It's been forever since I had any problems with FIrefox, and must admit I have forgotten most of the troubleshooting tips, that I used to know. But I did remember those, unfortunately none of those are the problem.

What else can I try? Thanks in advance.

BTW: I am submitting this on my phone because this is one site that won't load. If it did I would, I would click the "Share Data" button.

https://support.mozilla.org/en-US/kb/https-upgrades SSA says Firefox will "upgrade" me, but their provided link doesn't go anywhere helpful. I tried doing several things I found on the help page https://support.mozilla.org/en-US/kb/https-upgrades "Firefox connection upgrades - HTTP to HTTPS ", but I still get this "Forbidden Access".

I have tried to contact SSA (left an e-message) and will keep trying, but my God, they were impossible to get by phone even before Trump and Musk cut everything, so I'm not going to even try that. Can you help me?

Logs out of email (gmail) after restarting the browser. I reinstalled windows and downloaded a browser, connected my account, and now when I go to gmail.com and register my mail, everything is fine, it works, but when I exit the browser and go back to gmail.com, there is nothing.

Hello everyone, As possible in previous Firefox releases I like that clicking on a .mdb file (msaccess) Firefox starts automatically Microsoft Access rather than asking where to save the .mdb file.

Thanks and regards Volker Zipp

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

I am not sufficiently computer literate to understand supposed help and support documents within 'Mozilla Support'

It looks like the end of 20 years of using Firefox ... Google Chrome used to submit this request

After updating to version 138.0, the browser put up an announcement page that informed me that I now have access to a great new feature, tab groups. It's actually a great addition to the browser IMO.

But it's absent. I read the announcement page, then the help page it links to. Every description is inapplicable to my browser, there us no drag-over behavior for tabs, there is no "add tab to new group" option when right clicking. I updated to 138.0.1, same thing. There is a topic in Connect.mozilla.org about tab groups as a beta feature, and it's been up in beta since March. But my browser does not have it.

Granted, the help page vaguely says that no all users will see this feature as it's rolled out gradually until May 6th. But why then tell me that I already have it on update? And why is it rolled out gradually if it's already been in beta?
