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.

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

So I downloaded a font, It was a helvetica one, and now it shows up on specific websites. I deleted it, restarted my computer, (which also got stuck on the restarting screen) and it still shows up. I probably wouldn't mind, but the font doesn't really look so good, so I need help!

In the image, the font is supposed to be roboto, but it definitely isn't that!

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.

I clicked on an add (will never do that again) that advertised making money by reviewing movies and TV shows that you watch. Wheen the website opened, it really wasn't that, so I closed it. Then every time I would open a new website, a tab with that site would open automatically.

I went to Settings, Privacy and Security, Website Privacy Preferences, Cookies and Site Data and cleared data. I also clicked on Manage Data and removed the website from that list.

It didn't work. Any ideas on how to get rid of this really annoying invasion of my computer and privacy?

Thank you! oh

My ISP is VirginMedia and I use their Webmail system for all of my email requirements.

I have FireFox set to download new versions when issued and upgrade when my machine is rebooted.

I rebooted yesterday and the new version FireFox (v138.0.1 (64bit)) was installed.

When I checked my mail later on I got the message:

   Error: Failed to load messages.  Retry.

And that has remained the same for more than 24 hours; none of my folders are accessible and I have been unable to send mail; I have 44 messaqes in my Inbox and 2 in my Spam folder.

I contacted Virgin's Tech Support earlier this evening and they were unable to find any faults at their end, and they suggested trying another browser (which I was loathe to do since FireFox has been my choice for more years than I care to remember ~~ but I bit the bullet and installed Opera - and found that I was able to access my webmail and all of its' folders at Virgin.

Please tell me that there'a fix on the way, I don't want to switch from FFox and nor do I want to run two browsers at the same time.

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.

At first, I though this was just an update issue. Perhaps a settings issue. Every time I open a new tab or even enter a query and press enter, I'm sent to my settings to "turn on location." I go back to Firefox and there is a Pop Up telling me to "Grant Firefox location permission in system settings." 1. No, I will NOT share location globally via system settings. 2. Windows OS is up to date 3. Firefox is up to date 4. I run Norton AV 5. System seems to be operating normally, other than that.

Device name IdeaPad Processor AMD Ryzen 5 7520U with Radeon Graphics 2.80 GHz Installed RAM 8.00 GB (5.74 GB usable) Device ID Product ID 00356-07422-06058-AAOEM System type 64-bit operating system, x64-based processor Pen and touch Touch support with 10 touch points

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!

please, can you help, BECAUSE THIS ALWAYS HAPPENED ON FIREFOX FOR ME, EVEN A YEAR AGO IT ANNOYED ME SO MUCH I HAD TO SWAP TO CHROME THAT LAGGED BADLY FOR ME, i genuinely have 5-6 gmail and i don't want to log in them every day or week, please, help me

Hallo Firefox-Support,

System: Windows 10 x64 Ich habe Firefox komplett neu installiert. Es ist kein Benutzerkonto synchronisiert, das Profil ist komplett leer. Vor der Neuinstallation habe ich alle drei Mozilla-Ordner in AppData (Roaming, Local, LocalLow) gelöscht und den PC neu gestartet.

Leider besteht folgendes Problem weiterhin:

Wenn ich auf https://www.google.de/maps/ gehe und ganz unten rechts auf „Feedback zu Produkt(en) geben“ klicke, und anschließend auf „Straße hinzufügen oder korrigieren“, dann lädt es unendlich – es passiert nichts.

Ich hatte gehofft, dass das Problem nach der Neuinstallation behoben ist, aber es besteht weiterhin. In anderen Browsern (z. B. Chrome oder Edge) funktioniert es sofort und ich kann direkt Straßen auswählen.

Ich bin ratlos und hoffe auf Ihre Unterstützung.

Anbei der Konsolen-Text aus den Firefox-Entwicklerwerkzeugen, nachdem ich den Fehler erneut ausgelöst habe. Benötigen Sie noch weitere Informationen oder Logs von mir, um das Problem besser untersuchen zu können?

Freundliche Grüße Fabienne

Hello Firefox Support,

System: Windows 10 x64 I have completely reinstalled Firefox. No user account is synced, the profile is completely fresh. Before reinstalling, I deleted all three Mozilla folders from AppData (Roaming, Local, LocalLow) and restarted my PC.

Unfortunately, the issue still persists:

When I go to https://www.google.de/maps/ and click “Send feedback” at the bottom right, then select “Add or fix a road”, it loads endlessly — nothing happens.

I had hoped reinstalling Firefox would fix it, but the issue remains. In other browsers (e.g., Chrome or Edge), it works instantly, and I can select roads without any problem.

I’m out of ideas and would really appreciate your support.

Attached is the console text from the Firefox Developer Tools, captured right after reproducing the issue. Do you need any additional logs or details from me to investigate this further?

Kind regards, Fabienne

middle mouse button isnt working since update.

i had it so that a middle click on it would open a new tab to the right of the other tabs.

i have looked and checked browser.tabs.opentabfor.middleclick and its TRUE.

any suggestions. it is just since update i'm sure of that.

Hello, for some reason after the update I can no longer load the game Elvenar, when I type in the name and then click on any link i'm getting https://en-play.elvenar.com/?lps_flow=after_glps_shim

and the page won't load and I have a black screen as per the screenshot

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

I have been developing an Angular website that's served on port 4200 on localhost. Up until now it only accepted http connections, but I've now upgraded it to https. Firefox has about 50 credentials remembered for this site and it's always worked fine, but if I go to the https URL, it totally refuses either to show the existing password OR pop up the dialog box to add it for the new URL, so I have to type the password every time. I've disabled all extensions as suggested and it still doesn't work, although for the http URL it still does. I've not added any code on the site to discourage saving credentials. What do you suggest?

Firefox consuming too much Memory, ranging from 1800 MB up to 2000 MB, causing my other programs (most notably Corel WordPerfect) to constantly crash. How do we resolve this?
