Firefox Support Forum

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

Any method I open a new tab, it always takes up to 7s to load, while completely suspending my browser. This also happens in troubleshoot mode but not in incognito. Directly opening websites in a new tab doesn't trigger that bug. I don't recall when this started to happen, it might be after some new Windows update.

I have included screenshots from Firefox Profiler, both from regular window and incognito one.

Subject says it all, but it seems to occur with any site, anytime I try to open more than three or four tabs (ctrl-clicking links on a forum, for example) my Firefox instance grinds to a halt and starts consuming most of my CPU (Ryzen 5 3600).

I've tried turning off Firefox's various protections. I tried troubleshooting (formerly "safe") mode, and the problem isn't as bad but is still present as far as I can tell. The only extension I can think that would be making it worse is Tree Style Tab, but I don't know enough about interpreting Firefox profiles to verify.

The only reason I consider this odd is because doing the same thing in Chrome doesn't have this issue on this same device. If I open many tabs quickly, Chrome itself is still responsive. Those newly opened tabs may take a while to load and become interactive, but it doesn't affect the rest of the application. I pay my ISP for gigabit DSL, and as far as I can tell that is roughly what I get. In my case, Firefox doesn't behave this way.

MS Edge works just fine.

When trying to set up alert notifications for FEDEX tracking status, the Submit Button remains active, even after filling all required fields and checking all required boxes. See website:

I have set https://www.fedex.com/ as a trusted site (Exceptions), and turned off Browser Guard. Also placed same URL in MalwareBytes allow list.

I was told to click on the video area to solve a problem with text displaying The solution seemed quite simple But I cannot see any video area on Firefox Version 122 I looked at all the View drop-downs including Toolbars, Sidebar, Zoom, Page Style I tried clicking everywhere but nothing worked Can anyone tell me where it is? or how to get it to display?

For some reason, Firefox just stopped working yesterday. The only way I could get it to work again was to uninstall and reinstall (the refresh option did not work). However, now I've lost all my bookmarks, passwords and customization. I don't care about the customization and losing the bookmarks is an annoyance, but I'd REALLY like to get my passwords back. The installation created a folder of Old Firefox data, but when I open the folders that I think might be helpful, like bookmarkbackups, they are empty. Is there anywhere else I can look where these might have been saved? I did not have a Mozilla account so no profile until now which I just set up in order to access the forum. Thanks for any help you can provide.

I have changed Firefox's settings to both Delete cookies and site data when Firefox is closed and to Clear history when Firefox is closes. But after making these changes Firefox is still holding onto my browsing history.

All of a sudden (started today) Firefox will not load ANY websites, except Mozilla/firefox websites. All previous bookmarks, links, and typed in addresses do not load. No changes to virus protection, browser, or any other updates. Other browsers (chrome, opera) work fine.

previous version of firefox , open with option work perfectly. But latest update , it won't work anymore such as potplayer://url... i don't know why but this is working perfectly on other browsers such as chrome...

The most recent update to Firefox introduced duplicate 'Manage Bookmarks' option in the bookmark drop down. Is there a way to remove the bottom one in an option that I'm not finding? The only thing I've found searching is from a few years ago talking about setting up a CSS file, which I've never done before.

When streaming a video and using PiP, after opening another window or program and then pausing said video that is currently being played on the PiP player window, sometimes this causes the actual video itself being played via the PiP player window to freeze. So the video is paused and I want to resume play but when clicking the 'play' button on the PiP player window the video refuses to play.

The only way to clear this bug is to click the 'close' button or the 'back to tab' button on the PiP player window and then refresh the actual web page. After refreshing the web page and repeating the same steps - the PiP player window works just fine with playing and pausing, but it's annoying that I have to do this.

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

Trying to stream shows on Firefox and video does not start / errors out. Philo returns with this error: Philo is having trouble streaming this content.

[Error code: pf-1.5-5bb2f]

Paramount+ Also freezes up and returns error message. As does Amazon Prime.

Adblockers disabled. Youtube is fine.

Tried refreshing Firefox / renistalling but same error. Prefer to use Firefox as default browser but having to go to Google to stream shows.

Debating rolling back a version but it was working fine the other day but could have had an update and didn't notice and now streaming is erroring out.

Suggestions? Thanks.

I have the following settings in Settings/Preferences>General:

Files and Applications

Downloads Save all files in the following folder: Downloads Ticked Ask every time where to save a file

Applications Portable Document Format (PDF): Open in Firefox How should Firefox deal with other files? Ticked Ask whether to open or save files

On specific websites when I click on a pdf link, Firefox opens and automatically saves the file to Downloads folder without asking whether to save and where to save despite the above settings. As far as I remember, on other websites when clicking a pdf link Firefox only opens the corresponding file and doesn't save.

I found this with a internet search https://connect.mozilla.org/t5/discussions/stop-saving-pdfs-to-downloads-when-viewing-in-firefox/td-p/10225.

How can it be disabled that Firefox automatically saves PDFs?

picture-in-picture for videos on the normal instagram feed and posts. It worked last week, it doesn't work now. The little black square doesn't show up on hover anymore, I can't right click at all on videos now.

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.
