Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Issue Summary: When using a maximized Firefox window with the Windows taskbar set to automatically hide, the taskbar sometimes fails to appear when moving the mouse cursor to the bottom of the screen.

Steps to Reproduce:

  • Set the Windows taskbar to automatically hide.
  • Maximize the Firefox window.
  • Use Firefox normally and intermittently move the mouse cursor to the bottom of the screen.

Expected Behavior: The Windows taskbar should appear when the mouse cursor is moved to the bottom of the screen.

Actual Behavior: The taskbar does not appear consistently when the mouse cursor is moved to the bottom of the screen. This issue is specific to Firefox and occurs frequently, though not every time. The taskbar functions normally with other applications.

System Information:

  • Windows Version: Windows 10 Pro 22H2 x64
  • Firefox Version: Firefox 127.0 (but happens at least since 126.0)

Additional Notes:

  • The issue has been occurring for several weeks.
  • No specific pattern has been identified regarding when the taskbar fails to appear.
  • This issue significantly impacts the user experience as it disrupts workflow and navigation.

Steps Taken to Resolve:

  • Checked for and installed the latest Firefox updates.
  • Restarted Firefox and the computer.
  • Verified that the taskbar behaves normally with other applications.

Request: Please investigate and address this issue in a future update. Any guidance or interim solutions would be greatly appreciated.

Thank you for your attention to this matter.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

Having Firefox open reduces all download speeds, upload unaffected

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

  • Rebooted
  • ipconfig /release /renew /flushdns
  • Removed and reinstalled the network adapter
  • Enabled, disabled windows auto tuning and tested (slower disabled)
  • Updated Windows
  • Refreshed Firefox
  • Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

this site sucks by the way keeps eating what i type

Firefox version 127.0 Ubuntu 22.04.4

bookmarks toolbar under address bar broken setting set correctly for it to be there and there is a blank space for it to be there but none of my bookmarks that are in that folder show up changing the settings make the blank bar disappear and come back see screenshot.

Firefox home page is missing even though it is set to display just get blank screen on both new tabs and at start up of browser even though it is set to show Firefox start screen.

now every time i start Firefox it demands my master password for my passwords? just hitting cancel makes it go away though.

right click copy only works like 1/4 the time allot of the time the even though the text is highlighted copy is greyed out but using control+c usually works. that one has been happening a wile though.

Hello! Hope you reader are doing well. Sometimes, I'll even dare say most of the time, when I browse YouTube on Firefox and enter a video - it loads fine (currently 😢) but the thing that says what the browser is doing right now - I don't really know how it's called, sorry - keeps showing, and the only way for me to remove it when it's stuck is to refresh the page. It is a small yet annoying problem, and been persistent through Firefox's updates. Thanks for reading and helping to make Firefox the best!

I know it seems like a minor thing, but I run my browser in the left hand of my screen with other apps to the right, so that gaps pushes all my pinned tabs and browsing tabs over to the right losing valuable space. It's not there on my Windows machines where I run a similar layout.

Anything that I can do about it in about:config?

Hi

I just clicked on my Firefox to open it and was met with a new update tab, and all my tabs had disappeared, which I have had happen to me in the past and ended up losing everything after closing Firefox and reopening it again.

So with that in mind I went to History and everything was greyed out, and so had no option but to close my browser, thinking that maybe that it had opened that one to tell me about the update and if I reopened it all my tabs would be there. Is there anyway I can retrieve all my tabs?.

Thanks

Firefox 127 - close tab button missing for background tabs when more than 10 tabs opened

In previous versions I was able to open around 15-20 tabs before X button disappeared from them and I was no longer able to close them without activating them first.

Now this happens much earlier - only 10 tabs is enough on my 1080p 100% scaling desktop and 9 tabs on my 1080p 125% notebook.

X button is present if you have 10 tabs or less, but disappears with 11 tabs, when there is still plenty of space on tabs to click on X!

I compared it to brave and in brave you can still have 22 tabs opened before X button disappears!

Anyone has any method to force presence of x button? This is really annoying as I often have much tabs open and close only 2-3 of them. Now I have to open each one again to be able to close it.

Customize Links on Firefox New Tab Page

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

Even though I have browser.privateWindowSeparation.enabled set on "false", private windows appear separate regardless and it is bothering me. I restarted my browser, logged out and then back in, toggled the setting on and off again, but the damn thing stays in this uncomfortable spot that would be awkward to explain as opposed to simply having it blend in with the other windows innocuously. How do I fix this?

The icon for private browsing has recently re-appeared on my taskbar despite having browser.privateWindowSeparation.enabled set to false in about:config.

I've had this setting configured ever since the update which completely changed the appearance/behavior or private browsing and it has worked correctly up until today (14/06/24).

Is there a new setting that I have to adjust in order to "merge" the windows together as I'm not a fan of having the private browsing icon on my taskbar.
