Firefox Community Forum

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

Please read below my emails to Ghostery support that describes the issue and the Ghostery response.

The issue is using DuckDuckGo in Firefox with the Ghostery add-on enabled, and changing DuckDuckGo AI settings.

Please let me know if there is a resolution available.

Thanks, Malc [edited] @gmail.com __________________________________________________________________________________________

An FYI -

Ghostery Tracker & Ad Blocker - Privacy AdBlock 10.4.32 has an issue in Firefox with DuckDuckGo search engine Settings changes to AI Features, Chat to off, Assist to Never, then saved and shown working with a page refresh.

When Firefox is then shutdown and restarted the intended DuckDuckGo browser changes are not applied. Assist will still show a result in a search.

Proven by disabling Ghostery, again changing DuckDuckGo AI features and saving, shutting down Firefox and restarting, then searching with DuckDuckGo with no Assist displayed in result.

I can answer any questions you may have.

Regards, Long time happy Ghostery user Malc [edited] @gmail.com

Hi there,

Thanks for reaching out to Ghostery and bringing this to our attention!

We were able to reproduce the issue on our end, though with slightly different conditions. It appears that DuckDuckGo’s settings are stored locally in the browser. If Firefox is set to clear cookies and site data (either manually or automatically), this would reset DuckDuckGo’s preferences each time — even with Ghostery disabled.

Could you please check if the option “Delete cookies and site data when Firefox is closed” is turned off in your Firefox settings and try again? In our tests, DuckDuckGo’s settings were preserved when this option was disabled. It would greatly help to narrow this down.

Here for any further questions! Best, Ghostery Support

Hi Ghostery Support 2,

Thank you for replying.

Yes, the option “Delete cookies and site data when Firefox is closed” is turned on. When turned off and the Ghostery extension enabled, the changes to DuckDuckGo were saved and implemented correctly when Firefox was restarted.

I did find this.

In Firefox settings Cookies and Site Data, Manage Exceptions, I added "https://duckduckgo.com" and set Status to Allow. I also turned on “Delete cookies and site data when Firefox is closed”.

With the Ghostery extension enabled, the saved settings to DuckDuckGo were still active when Firefox was restarted.

But I do not think it wise to give DuckDuckGo an exception to use cookies and site data with no restriction.

Please keep me informed.

Regards, Malc [edited] @gmail.com

Hi there, Thanks for getting back to us!

Unfortunately, there’s not much Ghostery can do in this case. If DuckDuckGo saves its settings internally, there may be no way to keep duckduckgo.com out of exceptions while preserving those settings elsewhere.

You might want to look into third-party tools that support this kind of setup, or consider reaching out to Mozilla’s support team with this request.

Here for any further questions! Best, Ghostery Support Support Ghostery

Does the Relay extension only work on Firefox or can it be added to other browsers? It seems like a useful tool, but I don't want to be locked into a single browser.

Hello, everytime I try and upload a video on YouTube with firefox, the video gets stuck at 0% processing,

This never happened in my 4 years of youtube and recently (a few weeks ago) this starting happening. I use firefox to stricly upload videos, and use chrome to browse with my other account casually.

Now Im forced to upload using chrome but I want to still use Firefox to upload videos. anybody know why this is happening? I've cleared cache serveral times and it still won't work. I have no adblockers etc.

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

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?

Windows 11, v23H2

After the last update, I have a problem opening some links just with a left click. Most open fine, but on some sites, I can open the site fine, but all other links have to be opened in a new tab. Sometimes, I can't even get that menu to come up, so I have to save the link URL and open it in a new tab manually.

I have my browser set to open all tabs in a new window, so that's not the problem.

It's very annoying, especially when I'm trying to get something done quickly.

How do I fix this? TIA

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

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

I just got a new pc, and added Firefox, and also imported all of my bookmarks. But I don't see any way to add tiles to the new tab page. There are no Tiles there, even after 3 days. I really like having the links I visit most listed in tiles on the new tab page. Why don't I have any and how can I add them? I don't see anything the settings, and the help answers don't help because there are no tiles to right click on.

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

- Translated via Google Translate.

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

When I hold control on my Mac and click on a Tab the box that opens has no option to rename or to group the tabs together....I am running Firefox 138. Clearly I am missing something. It offers a function that would save me a lot of time, I hope you can help

Can you allow someone to get on my computer to help me? Or do you have a phone number I can call safely to have someone go through things with me, if I need help? It stated when I put it on that is is "poor" in terms of what you did. Maybe I am doing something wrong??

Gmail will not open with Firefox as of Wednesday 5/18/2025. I do not have any adblock extensions running.

Gmail opens fine in Chrome.

Any suggestions?

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, after installing a new hard drive (the old one died and I couldn't recover the data), I reinstalled everything on my PC, except that a friend recommended installing Arium (Windows 10.8 LTS). It works fine, except that now I have no way of connecting my Mozilla account to Firefox to recover my passwords and other saved tabs.

I've searched a lot, tried several installations, and even installed a previous version of Firefox, but nothing works...

Do you know why? Is it because of Arium?

Thanks
