When playing YouTube videos in fullscreen mode, the video appears to skip as would be expected with frame drops. However, with stats for nerds open on the videos, no frame drops are reported and buffer health is fine (40+ seconds).

I'm on an up to date version of FireFox, I've tried with hardware acceleration both enabled and disabled, I've tried opening task manager to see if system usage looked weird (it doesn't, although it's not like I can have TM running while the video is playing in fullscreen so hard to tell) and am at a complete loss. All drivers for CPU and GPU are verifiably up to date (did full system check three days ago) and the only conclusion I've been able to come to is that it must be either a problem with FireFox or a problem with YouTube. I've seen no recent reports on any of the forums that I can find pointing to either as the culprit. So if anyone has any further ideas or solutions, I'd love to here them.

When browsing on IMDb (see image attached) when I click on the "See All" button just above "Soundtrack" at the bottom of the image nothing happens. This should expand the list above it, in the case an actor's credits. I have NoScript 13.5.2 installed but all scripts are allowed here. I get this on all the IMDb pages.

Is there anyplace that shows how to use what the new release says on the 146.0. I got the message below when viewing new options in 146.0, but going to settings, sync just wants me to sign in and do a cloud backup.

Doesn't sound like what is in message below that I got after updating to 146.0. From what I found looking around, you are suppose to go to setting, sync, click on backup and choose location. There is no option backup, just an option to sign on. Below is message I got when checking what is in update 146.0:

Windows 10 users can now automatically protect their passwords, bookmarks, and more by turning on backup in Firefox. Your browsing data is saved daily on your device and can be encrypted with a password When you set up a fresh install of Firefox on any operating system for a new device or your current one, you can restore from this backup and pick up right where you left off. This feature is currently available on Windows devices and will be coming to other operating systems soon.

Hello,

I work for a company that integrates with Netsuite via SSO. Users should not be required to reenter their credentials to access the integrated app via a NetSuite subtab. However, this has been an ongoing issue. I thought it had something to do with cookies, but I cannot figure out what is causing this. Here's what happens: A user logs in to Netsuite, looks up a posted document, and clicks on the subtab of the integrated application. They are then prompted to enter their credentials. This prompt keeps repeating whenever the user refreshes a page or opens a tab. It seems like the browser is not retaining or saving the user's credentials. This does not happen to Chrome or Edge users. Is there anything you can do?

Your assistance is greatly appreciated.

Regards, Mac

Recently upgraded to version 146.0 on Linux (Mint, Cinnamon)

YouTube will work fine when I first start the browser. Eventually videos will stop displaying and sidebar links will not be active.

From a separate forum article I cleared all site data and restarted Firefox. That fixes the problem for about 4 or 5 videos, then you need to rinse/repeat.

The latest incident seems to have been triggered when I tried to watch a video embedded in an X (Twitter) post. That failed. And the YT failed as a whole. X was open in a separate tab container at the time.

While I have both Privacy Badger and uBlock Origin installed, both are deactivated for YouTube.

See the attached images. The video is just not displaying, though the screen is reserving space for the player.

Both/all videos I have tested do work in Chromium.

Since Version 145.0.2, November 26, 2025, 1. firefox won't print anything anymore. No matter the way that I select something to print (print to PDF, print to printer), firefox won't print anything anymore. The print options screen does pop-up when "print" is selected , but when "print" is selected on the print screen pop-up nothing happens. This includes the "print to PDF" function as no "save to" file folder pop-up opens to select where you want to save the pdf file to. After an update prior to the "Version 145.0.2, November 26, 2025" firefox no longer allows you to move your tabs from their original positions to the left or right along the tab bar in the browser. I use to be able to click on & select one or more tabs and move those tabs anywhere to the left or right of their original position to anyplace along the tabs bar. NOW at present, the only way to move any tab's position is by "right clicking" on the tab, select from the drop down "move tab" and selecting 1 of the 3 options ("Move to start", "move to end", & "move to new window"). You can also add tabs to groups through the "right clicking" process. Unfortunately you can't simply move tabs in any other ways without using those "right click menu options. This is VERY frustrating because I constantly move tabs (or strings of tabs) to better group them without having to add them to specific "groups". And speaking of groups, you can no longer rearrange the tabs in "groups" either.

These are both some of the most basic and general functions for firefox that no longer work in firefox 64 bit on windows 10 OS (my primary PC, but the same holds true on Windows 11). You should also note that recent updates also occured on both Windows 10 & Windows 11. I am still currently able to print from and move tabs in the Edge browser which I have had to start using more & more since these functions stopped working in the firefox browser. I've always preferred using firefox even though it is a huge resource hog, but if firefox doesn't fix these problems soon. I will have to resort to using the Edge browser over using the firefox browser. That reminds me of a 3rd problem with your "unload tab" function, 3. The "unload tab" function ONLY works if you click on and open the single tab first. The "unload tab" function ONLY WORKS for a SINGLE TAB at a time. When/if you select multiple tabs and select the "unload tab" function in the "right click" drop-down, ONLY the first tab selected and that you are currently on, using, and viewing will "unload" while NONE OF the remaining selected tabs will "unload". You need to make a way to "unload" ALL TABS that you are NOT currently viewing/using as "unloading" tabs one at a time is painfully tedious. The "unload tab" function would be a great idea to reduce firefox from being the huge memory hogger that it is, but only if you make using the "unload tab" function's use less tedious. Perhaps Mozilla should consider making the "unload tab" function less necessary, by either making the "unload tab" function automatic and not NEED to run every opened tab until said tabs are actually in use & actively being used OR BY making firefox less of the enormous resource hog that it has become.

As the title says , im really hoping for a small change that will happen from Firefox team or an addon , since i started using vertical tabs it was the best thing ever happen. however im really just hoping to have the option to increase the icon size of the tabs, i usually just have the icons showing without the name of the tab thing, but my only need is just to have the ability to increase the size of the icon tabs thats it

To whm it may concern, Having the same problem as others with homepage shortcuts and Its absolutely absurd - I want FAVORITES shortcuts on my home screen, not shortcuts for every flamin page I visit (mind you, your new shortcuts creation option is designed so poorly, if I sign into something like an email account, it saves shortcuts for the initial page, the login page and the landing page! - Seriously Mozilla??) The box you once checked to save favorite site shortcuts now says "sites you save OR VISIT". Thats just utterly ridiculous, especially when I have set cookies and history to be deleted on browser exit.

PLEASE FIX THIS - Not user friendly in the least Thank You

I've been using Firefox since forever but over the last couple of months, the auto translate subtitles (to English) hasn't been working when watching Youtube videos. There's a thread on the Youtube support site with nearly 40,000 posts of people with the same issue and tonight I was trying to watch a video where the hosts talk in Italian, so I use auto translate to English subtitles but no subtitles appear. It will show Italian language subtitles.

I've gone back through this Youtube channel's history trying videos I've previously watched from months/years ago when auto translate used to work but even they're not working now.

I decided to try the video in Edge browser and to my surprise the auto translate to English worked there. They also work in Chrome.

So what could be causing this issue on Firefox, which started about August time?

This is quite bizarre as I assumed all the processing/translation was done by Google/Youtube so in what way can Firefox be part of this issue?

To be clear, subtitles in the (foreign) language the people are speaking, works. Subtitles translated from that language to English (or other languages) has stopped working. Subtitles translated from that language to English IS working on Edge and Chrome browser.

I sent message below to Bluesky support and have tried all their suggestions (all relating to Firefox), but to no avail.

MacBook Pro OS 10.14.6. Yesterday (9Dec2025) I could open Bluesky & see my profile but could not add a new post. I then did an ‘age verification’ and received confirming emails. When pressing ‘New Post’ button just went to blank page. Under ‘notifications’ at the top, was a message “''''! r.countGraphemes is not a function''''”. I am accessing using ‘Firefox 115.31.0esr (64-bit)’. I have deleted caches, re-started ‘Firefox’ and re-signed into Bluesky, but problem persists.

Could you please advise how I can overcome this problem. Thank you, best regards.

I had so many instances of firefox and tabs that i decided i must organize them on tabgroups, i read they were secure enough and would be restored along with open tabs on new session. But after restarting all my "close and save" tab groups are missing! are they still saved? how can i recover them?
