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.

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

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.

We have a W10 workgroup using an unmanaged switch to hook 5 PC's together through hardwire ethernet. The switch is also the access point to the internet "modem".

I would like to cause the PCs to use wifi to access the modem ONLY for internet and Thunderbird, with the workgroup remaining on the wired system.

With both "networks" enabled in W10 the PCs are automatically defaulting to whichever method was enabled 1st. I have no idea how or if I can "split" the flow and cause FF and Tbird ONLY to use wifi.

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.

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

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

Hi, how can I zoom in and out on websites without changing any display or layout? For example, on some sites, zooming changes the layout of the text so that it all fits on the screen. Or zooming on some sites doesn't affect the size of the images, only the text. How can I zoom in so as to see the page in its original layout but with a wider view, thus preserving the scales of all the elements (as if I were zooming in on a picture) ? (in the screen below, zooming change the relative scale of the elements) Thank you for your help.

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

Something happened with your new update, and now my computer is not working. i cannot get my emails to come even though i choose the email button. The wheel just keeps turning and turning, and will not ever get to the emails. The same thing happens when i try other favorites buttons on the top of the page. i do not know the correct words to describe what i am trying to say because i am not tech savvy at all. i am a senior citizen who needs my computer to work again. What has happened? i do not understand any of the directions given to me when you have answered me today. i do not understand the details! i am very frustrated right now, and have spent a lot of my day trying to get my computer working the way it did yesterday. What has happened?

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

I have a Lenovo Win 11 notebook that now requires me to sign in each time I open Outlook or YouTube when I use the Firefox Browser. Edge and Chrome do not require a sign each time I use Outlook and/or YouTube. A setting in Firefox certainly seems to be the cause. I reinstalled Firefox, still same broblem.

A week or two ago I had no issues with Outlook and YouTube. It happens now every time I Open Outlook and YouTube.

I now use EDGE and have stopped using Firefox which has been my preferred browser for years.

Best regards,

Hi,

Just the other day I started getting these popups from "anti virus service" that keeps popping up on my screen. I do not nor never did have McAfee on my system. I did a deep search, and there is no program on my computer, nor in my startups, nor in my popups allowed relating to this. It is only a problem with Firefox. Any solutions?

Thank you, John
