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.

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

is there any way i can roll back the most recent firefox update? i updated firefox on june 12th and ever since than, i can not use firefox or open any tabs due to it continuously crashing over and over with no recovery. it is so bad that i had to go to microsoft edge just to report this problem, because i can not get firefox to open anything beyong my homepage without crashing the tabs. please email me at gnralee01@yahoo.com this is infuriating and i have to now use microsoft edge for my browsing because i can not use firefox until you fix this. i have uninstalled and reinstalled firefox 3 seperate times and i still get the same results. firefox worked great prior to the june 12th update.

Every other browser works fine. This one stopped dead on Win10 and Android9. It wont stream even in safe and my Android has no add ons

Hello!

I manage our browser configuration for our enterprise. We use group policy to restrict browser addons until they clear our internal security review.

I'm looking for a way to allow specific addons using group policy, while generally blocking everything else.

I've found the setting to enforce the installation of addons, but we'd like to avoid forcing every addon to install on every system as there would be overlap between things like password managers and such.

Is there a way to accomplish this?

For the last few months Firefox has released a stable version and a matching ESR version for OS's that are no longer supported. Firefox stable version had a major monthly release and a minor update as needed. For the next release scheduled in July I see a stable version of 128.0 with two matching ESR versions. I'm trying to understand the difference between the two ESR versions. The two versions advertised as ESRs are 128.0 + 115.13.

Thanks.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

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.

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?

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).

A while back the behavior of the ctrl+shift+t shortcut changed from reopening tab in the current window to reopening tab in the current window or reopening last closed window which for me and a lot of other people too made it worse. There's been a thread https://support.mozilla.org/en-US/questions/1421356 but it's been archived without a real solution. Is there now a way like a about:config toggle to bring back the old functionality? I really miss the old behavior.

When I open my emails, I get an automatic default to email REPLY. I cannot open my emails for reading and attachments. Also, I no longer get the time of the email listed. How do I restore my settings?

Hi there,

I'd like to know if there is a way to remove firefox relay from the context menu, as per screenshot. I really like the relay icon on the email fields, but I don't want it to show on the context menu and I found no such option on the relay extension. Is there a solution to this?

Thank you

Hello

I am using firefox 126.0.1 (64-bit) version of firefox on a linux system (kernel 6.6). Firefox is closing the main window abruptly (or crashing).

Wanted to get information on the crash, but when I navigated to the about:crashes page, it return a page with title "invalid URL" and the page says "Hmm. That address doesn’t look right."

Is there a way to get to the crash data/information?

Kind Regards Riza

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

My Windows 10 Pro laptop computer crashed a couple of days ago and no longer works. I am considering replacing it with a new Macbook Air. My files are backed up with Carbonite. Will I be able to get my saved passwords back by restoring my Firefox profile to the proper folder on the Mac? (I already know that Carbonite's backup program will not do a "file restore" between Mac and Windows; I will likely be paying Carbonite an extra $100 so they can put my files on an external drive and ship i to me.) | (I have a lot of the passwords saved in Safari on my iPhone and old iPad mini 2, but there are some I did not want to save on the mobile devices. They are also not on the much older Windows laptop I am currently using. Therefore, I cannot access certain sites right now unless I am willing to change the passwords.)

Thank you.
