Even with all media tabs closed, GPU process keeps hogging memory. Tried with extensions disabled, but no effect. The main culprit is this GPU process. screenshot attached.

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

Websites, even https website, will not load after update to latest version. Cannot even load https://www.duckduck.com. Your support website will not load. Have to use a difference browser than Firefox. Yikes!

I have a user that gets this crash report when trying to use certain sites like ebay and fidelity investments. Brand new PC, updated drivers, all fresh software installed. Very basic.

Suddenly, in last period I cannot open forms for verification, KYC precodures, chat windows. I deleted cookies from Mozilla settings but I lost all saved sites autmomastci access and I should install again, but nothing changed in forms for verification, KYC precodures, chat windows, are opened and close after one second,something do not allow to be appeared in screen. I tried icognito mode as customer support of a saved site told me but nothing changed. I scanned my pc with virus software installed but nothing appears as problem. What I must do in order to see again my favourite site forms and chat windows? I use Win 10, and latest Mozill version.

I work with a web platform where images can be optionally served from cloud storage, S3 in our case. This redirects image requests to a URL containing a dynamic signature which changes per request. For example, to load an image, the browser might do:

-> GET https://www.example.com/file.php/image01.jpg <- HTTP/2 303 See Other

 expires: Thu, 03 Apr 2025 11:23:44 GMT
 cache-control: public, max-age=14400
 location: https://[site].amazonaws.com/...filename%3D%22image01.jpg%22&X-Amz-Signature=...123

and the browser follows the redirect to get the image:

-> GET https://[site].amazonaws.com/...filename%3D%22image01.jpg%22&X-Amz-Signature=...123 <- 200 OK

But if I refresh the page the signature is now different:

-> GET https://www.example.com/file.php/image01.jpg <- HTTP/2 303 See Other

 expires: Thu, 03 Apr 2025 11:24:03 GMT
 cache-control: public, max-age=14400
 location: https://[site].amazonaws.com/...filename%3D%22image01.jpg%22&X-Amz-Signature=...abc

The browser doesn't have this URL cached so it again fetches the image:

-> GET https://[site].amazonaws.com/...filename%3D%22image01.jpg%22&X-Amz-Signature=...abc <- 200 OK

In Firefox that is. In Chrome there's the same following of the redirect when the page is first loaded, but when the page is refreshed the redirect has been cached:

-> GET https://www.example.com/file.php/image01.jpg <- HTTP/2 303 See Other (from disk cache)

 location: https://[site].amazonaws.com/...filename%3D%22image01.jpg%22&X-Amz-Signature=...123

Since the redirect is now to the same URL the image is fetched from the browser cache. Obviously subsequent page loads are faster on Chrome, much faster on image-heavy pages (for example, 6 seconds on Chrome, 1+ minutes on Firefox).

Is there anything I can do to improve this?

Tested with Firefox 136.0.2 and Chrome 134.0.6998.35.

This looks a little bit like [https://bugzilla.mozilla.org/show_bug.cgi?id=1889840 #1889840 will never use an entry in the image cache when loading an image top level that has a redirect] but I think that's referring to images with static URLs.

I'm using a few pages that need some time and a open connection to generate it's content (namely: A locally hosted AI). Accessing it from different desktop-systems works fine, but I noticed that Firefox Mobile (or Android) is terminating the connection as soon as my phone locks itself. Everything that the AI generates after is no longer displayed and I need to regenerate it. Is there a way/a setting to keep the connection open? So I can just set my phone to the side while the AI is generating?

Hello, I use the Firefox app for iOS but have the following issue with Greatest hits radio 60's find all that happens is that the page loads up but does not connect to the site. All I get is a circle at the bottom of the screen just going around and around. Any help would be appreciated

I recently installed Thunderbird on a new Windows 11 PC. Everything works except calendar reminders. My Thunderbird profile lives on the D drive so I copied my old profile.ini file which points to my Thunderbird profile on the D drive from the old pc at C:\Users\"ownwer"\AppData\Roaming\Thunderbird to the corresponding folder on the new PC. I have the latest version of Thunderbird, 136.0.1. All the events are Thunderbird created there is no connection to other calendars. I have tried reinstalling Thunderbird. The old PC was using Thunderbird version 115.5.1. When I tried to revert to version 115.12.0 I got an error message about the profile incompatibility between versions that related to version 68 i.e. "Unable to use profile when you launch an older version of Thunderbird". Please help.

I have a website with a lot of custom schema XML content that Firefox tries to interpret as HTML and display as "text only". However, I would like to see the XML markup instead. Up until a few weeks ago, I was able to right click and "View Page Source". However, now when I right click, I get an error message:

Content Encoding Error The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Nothing changed on my server, and the original behaviour (right click > view page source) still works in Chrome.

What do I have to change in my settings to permit Firefox display these XML documents for me like it used to?
