Hello,

I am having major issues with Firefox speeds, Mainly upload speeds. On Edge I am getting 400 up & down (no issues at all). However, on Firefox upload speed is 144 Mbps, same on private windows. The only issue is with Firefox. Windows is up to date and Firefox version is 139.0.4 (64-bit)

Attached comparison screenshots for reference.

Below are the steps i performed:

=========================

Firefox Troubleshoot Mode Test: Download: 411.71 Mbps (Full Speed) Upload: 173.03 Mbps (Still Bottlenecked) Extensions Disabled Manually (Normal Firefox): No significant improvement. Hardware Acceleration Toggle (Normal Firefox): No significant improvement.

=========================

New Temporary Firefox Profile Test: Download: ~333 Mbps Upload: ~190 Mbps Problem persists even with a clean profile.

=========================

Temporarily Disable Windows Firewall Test: Resulted in ~349 Mbps Down / ~148 Mbps Up. Firewall re-enabled.

=========================

Could someone let me know how to get this fixed. Creating a new profile should have fixed issued assuming one of the extensions was causing the bottleneck. But even with a new profile its not making any difference.

I wanted to create two profiles to separate my work and personal contacts. For security reasons, I also wanted to set up one account as the secondary email address for the other (I only have these two email addresses). Account A is a Gmail account and Account B is an enterprise domain account. Account B had the Gmail account as the 'secondary email'. However, when I try to access the Account A profile, I receive a red square message saying 'Primary account email required for sign-in' after entering the password. Perhaps I did something wrong, but... How can I access my Account A profile? Account B no longer has a secondary email address to prevent further problems.

Hello Mozilla Community, Every time I want to log in to Samsung.com and eu.community.samsung.com/t5/deutsch/ct-p/de, I have to re-enter my email address. The password is suggested. I'm not asked if I want to save my login credentials, but I'm asked for it on all other websites. I prefer Firefox to EDGE (it's suggested in EDGE). It's like this on Windows 10 and on my other computer with Windows 11 (both 64-bit and both up to date). What do I have to do so that Firefox also suggests the email address on these sites (asking whether it should be saved)? And I use a translation program from German to English. Again, thank you in advance for your reply.

After my laptop BSOD, I had to re-install windows 11 while backing up all the previous settings and apps. I used "Free Download Manager(FDM)" as my default downloader of movies from websites that generated Magnet links. On clicking the magnet link the FDM is not opening by default, no action is seen. I've tried many options including the Support Centre of FDM from where I was advised to visit my browser support. I have used Firefox for 14 years, let me know where I'm wrong.

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

Hi, as the title says, they stopped displaying after I installed the latest update for firefox for my computer (macbook air with the apple M1 chip). I have checked that in the settings I have "Show an image preview when you hover on a tab" enabled and that in my config I have both browser.tabs.hoverPreview.enabled and browser.tabs.hoverPreview.showThumbnails set to true. What could the issue possibly be now?

Again ONLY in FF harbor freight search function breaks when entering a search.

Yes, please don't give me the MS ctrl-alt-del type of response about cookies.... That was done many times before posting this. The website works fine in Brave. MS Edge well, let's not speak of it in public company shall we.

So, now what the heck is happening to FF???? I have contacted HF three times and they referred me to use other browsers other than FF. No, I DO NOT have multiple extensions nor themes. FF is bare bones but for uBlock. Hardware acceleration is off and MS Clear type is on. Anybody wanna fess up, who broke this????
