Firefox Support Forum

hey, i couldn't find any option for it, so i'm asking here. i switched from chrome to firefox but i noticed that once you reach a certain amount of tabs, you need to start scrolling through your tabs. how do i make it so, that all tabs are visible at once and theres no need for scrolling ? thank you

Hello everyone,

this here is a really odd problem and not one of the usual "firefox slow, internet bad" → "read the faq" problems as far as I can tell.

The problem: When using Firefox (110.0 64-bit Windows 10) I noticed already a while ago that downloads are slow, apparently frozen from time to time, websites took longer to load and looking at speed tests, I got really bad results. Furthermore, Firefox seems to slow down my internet speeds of the whole system, as I can observe in other applications which want to download or upload data. As long as Firefox is running (even if I am just in the default tab and doing nothing in Firefox) it slows the internet speed of the whole system down.

So I tried a plethora of things to fix this and I can rule out the following possible causes with high confidence:

• History, Cache, Add-Ons and so on: performed a clean re-install of Firefox, cleared all cache and history data, removed add-ons, reset to default, etc..
• ISP problem: performed repeated speedtests from other devices within the network, everything is fine within my local and wide area network, ISP does not report any problems
• Firewall & AV: turning on / off, even uninstalling, no effect observed
• Driver problem: driver updated, driver removed, used default Windows Driver, used Troubleshooter etc., nothing helped.
• OS issue: Nope. I even performed a clean new installation of Windows today, the problem remains. Furthermore: I ran the speedtests using Microsoft Edge and there are no issues (as long as Firefox is not running.)
• HW / System issue: Nopes again. I have used a live Ubuntu-image to cross-check whether the HW might be an issue, but running speedtests using Ubuntu and Firefox worked well.

I did not observe similar effects on other machines using Firefox under Windows in my network. So it seems to be a very specific problem within Firefox under Windows 10 on my machine.

By the way the machine: HP Pavilion Gaming - 15-dk0200ng CPU: Intel Core i5-9300H RAM: 16 GB DDR4-2666 SDRAM WiFi: Realtek RTL8822BE 802.11ac (via PCIe) (I also have an Ethernet chipset on this system, but since I have tested everything using only WiFi I'll omit the info here.)

So is this a bug of Firefox? Or am I missing something?

Attached are some screenshots of the disappointing test results using Firefox. (I have similar problems on other sites like speedtest.net or the speedtest of Google). As reference: I've got 500 Mbit/s downstream and 50 Mbit/s upstream. Usually these speeds are achieved from other devices (or other browsers on my system), or are at least within the top 80%. But what I get with Firefox is significantly worse. It's also strange that the speed goes up first, which is fine, but then falls down completely after reaching some point. A few seconds after that it goes up again, but much much slower.

Thanks in advance for any help!

Have to keep scrolling bookmarks folders from the top instead of being able to pick up where I left off LIKE IT USED TO BE.

Also, instead of being able to right click and open bookmarks in new tabs to try and speed things up, it immediately switches to the new tab, which means having to scroll from the top of the folder AGAIN anyway. And yes, I'm well aware of the "switch to it immediately" option in the settings menu, and that box is UNCHECKED in my settings.

I'm not the only one complaining about this time waster, yet no replies from support on any of the threads.

Why am I locked out. I play every day and today I can't get through and Google said it might be a Cookies issue. Need help please. Not very savy re. Cookies. I am a Senior.

When using Google Chrome, I can click on a telephone link and it brings up a dialog box asking if I want to make a call using my mobile phone.

Is this possibly with Firefox?

What is the fix for solving the issue of having to scroll back down through the same bookmarks in a folder, instead of the folder holding its place from where you were working? This is ridiculous.

Not sure what topic this falls under but...Sometime in the last couple weeks, Firefox doesn't want to connect to Facebook or You Tube. Just these 2 sites. All the other bookmarks and quick links on my home page work fine. If I clear my data and cookies and re-start FF it sometimes connects, sometimes doesn't, and sometimes opens FB in what looks like a safe mode screen (https?). Vexing me as to what the issue is. Updated FF, Windows, re-installed FF, refreshed it, and finally came here looking for a way to restore the default settings for FF. Since FB and YT are Alphabet companies, have they done something that's messing with FF?

Is it possible to put the titlebar minimise/maximise/close buttons onto the same toolbar as the address bar? I've used userChrome.css to hide the tabs toolbar (since I use Tree Style Tab), but I'd prefer not to have a titlebar either. Ideally my window setup would look like what's in the attached image, but with the titlebar buttons to the right of the menu button. So far I can't figure out how to do so (or whether it's even possible with a post-Quantum Firefox).

This issue occurred in firefox browser (110v), i can't open picture into another tab without a warning, reddit video player won't play, my home menu not appeared properly, bookmark also.

Whenever I try to fullscreen a Youtube video, it just displays a black screen. It is not temporary, and the picture never loads in. I have tried the full-screen-api solution. Didn't work. I tried deleting my cache and cookies. Didn't work. I tried disabling hardware acceleration. Didn't work. I restarted my machine twice, and that didn't work And I am on the most recent version of Firefox.

I am not fluent in English, there may be errors in translation.

When changing from theater mode to full screen, a black screen is displayed and the screen does not appear.

I searched Firefox for Merryfield Veternary services in Hamden Ct. The site gave a wrong telephone number and incorrect E-mail address and Hours of operation. Tried to get Merryfield to correct this error but they said it was on yelp and they could not correct it. My concern was that my pet almost died because I was calling the number listed which was not correct leaving messages on that number and not getting any return call. Then found out the errors presented in the web search to find their location. This should be corrected I almost lost my

I have 2 Windows devices, Surface Pro 8 & a Lenovo Legend, both almost identical Windows 11 build and same FF version(V110.0).

Only about 2 weeks ago, I started noticing these odd things on the Surface Pro 8 : - When first launch, FF window will open, and shuts down immediately. Second launch OK. - Few days ago, pw sync started to fail completely with the message "No synced Logins Found" when I go to the password screen.

I checked into my FF account and it tells me the both devices are signed-in.

Tried clicking on Sync in Levono as well as the Surface - no effect.

My Sync settings sync all syncable items.

Any user with Surface Pro 8 (running the latest Win 11 Update) has this problem? My Lenovo machine running FF normally.

Thank you.

Storage drive on my laptop got corrupted recently, So I got a new storage drive and installed windows on it. So I don't have any offline backup for my bookmarks. Is there any possibility that Firefox created any automatic cloud backup through which I can restore my bookmarks?

If not, how to setup automatic cloud backups for future.

Thank you
