Firefox Community Forum

While opening any Google Drive folder, or by opening docs/sheets start page, none of the contents show up. In the bottom left corner there is an error: "The server has encountered an error. Please try again later." . No amount of "trying again later" works , but through trial and error (disabling modified settings in another profile) i found the culprit of this error message: in about:config setting called network.http.referer.spoofSource was set to true, setting it to false makes the issue i described above disappear.

While my issue is solved, I still don't understand why on every Firefox profile i create this setting is set to true, and whether changing it is a security concern

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.

I am using Foxit PDF Reader with Firefox. When I receive a PDF in my email, I can't download it. Nothing shows up in my downloads file when I click "download". Why is there nothing in the downloads file? If I do the same thing using using Internet Explorer, the PDF Does show up in my downloads file. Why is this not working with Firefox?

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

After the last Mozilla update (138.0.1) the browser is now slow to load pages. You type in the website address or click on the bookmark and it takes minutes before the website begins to load. If you click on open link in new tab Mozilla freezes and if you wait it out 9 to 10 minutes later Mozilla comes good again and will open the link in new tab. No issues occurring before the 138.0.1 update. How can I roll back to the prior release?

Suddenly [with most recent firefox update?] Gmail is now in dark mode, and some of the emails show very light gray type and are unreadable.

My win 11 is set to light mode, and in about:config, the 'layout.css.prefers-color-scheme.content-override' is set correctly to 1 [lght], and oddly, it won't let me change it.

Gmail opens correctly in light mode in Edge, and also duckduckgo.

Firefox is my primary browser, and if I can't remedy this, i will need to switch  :-(

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.

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

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.

I reinstalled FF on 30 Apr 25 and it performed normally for a few days.

It is now 3 May 25 and we're back to where we started.

I started FF and I'm getting the tour screen on one tab, the privacy notice on another

All the tabs I pinned are just spinning their wheels

And all my extensions are gone.

Hi,

there are massive performance issues while playing videos on Youtube while using Firefox. This does not happen with the same video while using edge. The attached video shows the used memory and CPU of the youtube tab from the firefox process manager. This was taken after playing the video for 30s. Letting it run longer resulted in firefox taking up 20GB of RAM.

I think this happens since I installed 138.0 of firefox.

Could you please take a look.

Thanks.

Best regards

Hello, everyone,

I don't seem able to install Firefox on a Windows tablet (at least I think it's a tablet, it's an Asus Transformer Book, with a tablet screen and a detachable keyboard, anyway). Does anyone have any ideas why, please?

I should warn anyone before they read on that I am in no way techie, so helping me may be frustrating at times as I need advice/instructions etc spelled out really simply, as anything too technical is beyond me, I'm afraid.

So, anyone brave and/or patient enough to read on... I've bought the tablet secondhand, 'wiped' etc. It's an Asus T100HAN Processor: Intel(R) Atom(TM) x5-Z8500 CPU@ 1.44GHz 1.44GHz Installed memory: 2.00GB System type: 64-bit Operating System, 64-based processor Pen and touch: Full Windows Touch Support with 10 Touch Points

It's currently running Windows 10 Home, but I'm hoping to install Linux Mint on it, although it's only since I bought it that it's occurred to me that putting Linux on it might not be as straightforward as I thought, (ie I'm typing this on a laptop that came with Windows but on which I installed Linux Mint. "If Linux runs on this, it must run on anything that can handle Windows," I thought to myself before buying the tablet. But now I've realised that, eg, this laptop doesn't have a touchscreen, not does the screen have to rotate, which is the main reason for buying the tablet.)

That's sort of a digression, but might not be, as it explains why my priority right now is installing Firefox on the machine - so that even if it turns out I can't install Linux on it, at least I'll have Firefox rather than Edge or whatever.

So, in the Edge that came already on the machine, I accessed the official Mozilla page (despite getting several scary warnings from Edge about there being a problem with "this website's" security certificate, oh, and something about "Windows SmartScreen can't be reached at the moment") and downloaded Firefox. I went for the desktop version because that seemed more relevant than the Android or iOS versions. Then I've told it to "Run". The installer thing has come up and the little colour wave thing has happened with the icon in the taskbar (or whatever it's called). And then, after several minutes, I've got a message from Firefox Installer: "Hmm. For some reason, we could not install Firefox. Choose OK to start again." So I've clicked on OK, and the same thing has happened. Several times. And I've downloaded Firefox umpteen times as well, just in case there'd been an issue with that first download, only the same thing has happened, over and over again.

From the "about" thing, it looks like the 30GB or so of storage on the tablet, but about 10GB(!!!) is taken up by "system files to help Windows run properly. Your PC won't work without them."

Can anyone explain, please, what's going on, and what (if anything) I can do to get the wretched thing to allow me to install Firefox? I could just about cope if I can't get Linux, but no Firefox??? No, no no!

Thanks, Alice.

90% of time I cannot connect to a website unless I go into settings, privacy security and clear the data. Sometimes this doesn't work and I have to go to a different browser. I don't have this issue with other browsers. Why is this happening?

Just updated to Firefox for PC version 138.0.1 and lost a whole bunch of bookmarks, many of which I hadn't had time to save yet. Also, I can no longer save a bookmark. Would appreciate any help with this!
