Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

How can I move a tab to an open window? I know there is a function in the pull down menu to open the tab in a new window, but I would like to move the tab to a window that is already open. Google and Brave Chrome have a seamless, easy way on the pull down menu. I use it all the time, but I want to keep Firefox as my default browser. Thanks!

On a brand new powerful PC just signed in and there's no Add ons showing on this device.

I have two other devices where i have no issues, but this one...

What can i do?

Hello everyone,

I usually use youtube so the tab with youtube keeps crashing very often, but i think it happens it all webpages.

Here is the report bp-609d9162-75a0-4a6c-b65a-544480250628 https://crash-stats.mozilla.org/report/index/609d9162-75a0-4a6c-b65a-544480250628 with troubleshoot mode.

I m currently using the 140.0.2 (64-bit) of firefox on EndeavouOS.

(Ironically enough the firefox froze while writing this)

What should I do to stop the tabs from crashing?

Thanks

Alternative search engines no longer appear when typing the stasrt of a search. Am able to set alternative search engine in settings but need to go back to settings if I want to use another one. This happened after a recent update - perhaps as much as a week ago.

Hi everyone,

I'm using the Firefox browser (version 128.11.0esr (64-bit)) on MacOS (version 15.5 (24F74)) and experiencing a possible display bug in the ChatGPT website’s project window (as the attached Image-1.jpg shows).

When a self-defined ChatGPT project contains multiple chats, which means the right part of the website page needs to be scroll-able to show all its chats, it seems that it cannot be scrolled using Firefox, and no scrollbar appears. Yet I noticed that the chat list on the left can be scrolled normally.

Besides, I had another try using Chrome, and it work fine there (as shown in attached Image-Chrome.jpg.)

It's quite annoying since I have to switch to Chrome—not my default Firefox—to completely explore all my chats every time. Could someone please verify this and fix it if it is not just on my end?

I have a 120Hz display with dynamic refresh rate enabled in the Windows settings (48Hz-120Hz). With dynamic refresh rate enabled Firefox locks browsing at 60Hz. With dynamic refresh rate disabled Firefox shows all websites at 120Hz. Due to battery efficiency reasons I would like to use dynamic refresh rate but still use Firefox with 120Hz across all websites. Is there a hidden setting which I have missed? Thanks!

I'm writing an extendion wich needs to download a file:

```js

   let url = URL.createObjectURL(new Blob([content + '\n']));

   try {
       const id = await browser.downloads.download(
           {
               filename: "some_name",
               saveAs: false,
               conflictAction: "overwrite",
               url: url
           }
       );

       await browser.downloads.erase({id: id});
   } finally {
       URL.revokeObjectURL(url);
   }

```

If the file does not exist yet, it works great. If the file exists but is exactly the same, it still works. But if there is a need to override the file with different content, the file gets deleted and it is not being replaced.

According to inotifywait, the new file IS created, but immediately deleted.

Do I understand something wrong? What am I supposed to do?
