Firefox Community Forum

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

Since the update to 142, on pretty much every site it keeps jumping back to the top of the page. Happens on a lot of sites. For some reason, if I select some text at the top of the page it seems to stop this. A lot of people may not have discovered this. Mozilla just needs to fix it. I am using Ubuntu 24.04. Been using Firefox for many years. Never seen this before.

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.

What settings should I use to get the chat window to work on FireFox. The website is https://system76.com. I login and try to use the chat feature and it does not work. The chat feature does work on Chrome. I tired allowing notifications in Firefox settings, but that did not work. Are their any other setting should try?

I checked the box Allow Firefox to automatically apply exceptions required to avoid major website breakage and it worked, but I don't understand how this selection affects overall security.

Can someone help please: - I've been trying to buy some tickets for an event in France. When I access the following from Firefox (140.6.0esr (64-bit)) on Debian GNU/Linux 13 (trixie)) the ticketing purchase options don't show. When I access it from Chrome on Android or Edge on Windows it does show. https://www.circuitdesremparts.com/prochaine-edition/billetterie/ It seems I've now missed any Tribune tickets.

Thanks, Tim

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

I have an Investors.com account and a feature they offer is a stock sector data table that shows recent performance and other information. When I try to open these tables they close immediately, but if I use my tablet with a different browser they will remain open. I believe this is a simple setting that I need to adjust, but I don't know enough to figure it out.

Firefox in Ubuntu Linux is broken for about 30% of the web; only CHROME works. This problem just keeps getting worse. Please fix; it doesn't matter whether FF is more secure, if it doesn't work - what's the point?

Hi, I've been a use of FF since it was Netscape (yes I'm old). And its always been my favorite above all. However, with the recent update (ver 136, either installed from a .tar downloaded or an app via apt install) it starts fine but no matter what URL I try to access the busy indicator spins but nothing ever happens. I've tried disabling all my extensions to no avail. I'm also searched for others experiencing this issue. All my other browsers seem to work well on all the same sites.

I'm kind of at a loss so if anyone has any suggestions/ideas please share?

Thanks BobMCT

Hello, American website and the German website German website fail to load the last 20%. This causes important top row graphics like logins and accounts not showing. Firefox private window loads the AliExpress website 100%.

I wiped History cache from Firefox, however same issue. Other websites load normally. I can't log in to AliExpress to report the issue there.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

When I use on line banking and I want to look at a check, I can not get Firefox to render a check image. Also I downloaded tickets to an event and FF would not render the Q-code on the tickets. I what to know what settings to change in order to do online banking. BTW it works in Chromium Browser, but I do not use it and have little knowledge about Chromium, I just have it on my laptop for troubleshooting.

Here are the dpkg/apt logs for update:

2025-03-19 12:33:16 configure firefox:amd64 136.0.2~build1 <none> 2025-03-19 12:33:16 status unpacked firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status half-configured firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status installed firefox:amd64 136.0.2~build1

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.
