Firefox-Hilfeforum

Ever since upgrading to Windows 10, I've been having performance issues with Firefox. I've tried the beta, alpha, and stable versions to no avail. All give me grief. It's to the point I can't rely on Firefox like I can with the others.

It's only certain sites that give me performance issues; for example http://shop.lenovo.com/us/en/laptops/?menu-id=laptops After the images load, it hangs for like 5-10 seconds before it's completely good. Where as other browsers do not hang at all.

Here's what I've tried...

• Firefox in Safe mode
• Refresh Firefox
• Firefox Alpha
• Firefox Beta
• Firefox stable build without add-ons
• Trying the same site on Chrome, Edge, Internet Explorer, and Opera. All work fine except Firefox

Used performance monitor and noticed that my system is barely thinking when running Firefox and loading problem sites. So it makes me think it's software.

My system

Intel I7 5820K 16 GB DDR4 2400 MHz (4 x 4 GB) 512 SSD (Firefox installed on 7200 3 TB HDD) *I tried installing on SSD and HDD) Nvidia GTX 970 Windows 10 Pro Upgrade Comcast 180 Mbps down - 27 Mbps up speed Connection shared through R7000 router with custom firmware BitDefender AV

I enjoy using Firefox more than any other browser and would like to continue to use it. My standard browsing has one tab open at a time and problems occur, but when I work I use approximately 10-15 tabs at one time and I still have the problem on some sites, work related or not, and it's quite frustrating. I know Firefox is free so there's no real complaint here, just offering assistance to help better the product with some rant included :)

i had older version of FF for many years but latelly when i edit a private page he screen page jumps up and down horizontally and no action can be entered until the screen stabalises, i ahve latest 2016v of FF in an attempt to solve this problem, the problem persisits. we saw on your forum a rmedy for similar issue going into options and unchecking a certain box, i don't have this function with new version my wife does in her old version so was able to solve same issue by unchecking this function, what can i do please, i have had to revert to using IE

Firefox uses Celsius instead Fahrenheit on Accuweather forecast site. (Chrome does not). This only started a couple of weeks ago. How do I get it to switch back to Fahrenheit? I click on the *C but nothing happens. http://www.accuweather.com/en/us/cranford-nj/07016/daily-weather-forecast/334530

Have this issue two weeks already. (It is broken i think since version 43) Completely reinstalled Firefox with Full cleanup. (Deleted profiles) . Tried enable/disable hardware acceleration - Not working. Tried enable/disable Allow pages to choose their own fonts, instead of my selections above - Not working. Tried enable/disable all addons - Not working.

As the title says. Also there's no window control buttons, like close minimize and expand buttons, help! I can drag the window around as well, but just not resize it. See screenshot

I work with mozilla firefox. Since the last update of flash player I get a black screen and no sound when I want to look to a video. She enclosed picture.

In the add-ons I have flash player checked on "active always".

Please help.

This worked last year. I have VB8, VB 2015. VB 2015 works. I can compile programs and it works properly. All of a sudden, I can't compile with VB 8. I end up in Firefox. I even made Internet Explorer the default browser, just in case MS did something sneaky. But Firefox jumps up there with no website visible. I don't want to uninstall Firefox. Can somebody point in the correct direction?

Today when I opened Firefox it claimed I needed an update. When I pressed update it downloaded a file for me to run. This is as wrong as wrong can be. I stopped everything and went back in and discovered it is a hijack attempt. What would you like from me to investigate this incident?

Thanks, Fred

I am using Firefox synced on three different machines. On just this one, I cannot see any icons on most websites. All I see is the little box with 4 figures in it. I have checked and unchecked and rechecked the box that lets a site download it's own fonts. I have cleared the History of everything. I have tried starting Firefox in safe mode. No luck. Still can't see the icons. Any ideas? (I can't upgrade Windows as it's a university laptop)

Both IE and Chrome display all WU graphics w/o a problem. Latest Version 43.0.4 does not display 10 day forecast or the weather map. She has a Sony Vaio & win7 home premium. Adobe Flash is up to date. (My Dell win7 pro has no difficulties running the same updated programs).

So far I've totally failed to resolve this. Any help would be really appreciated! Thx

I'm using Firefox 43.0.4 and I tend to have quite a few tabs open, but recently I noticed the play/pause, settings, share etc elements to the Youtube playback window were missing. I tried a Firefox Refresh to clear out any cache issues and it didn't resolve the problem. Today while working in Google Drive I found the same problem, the little icons that should appear as UI buttons in the overlay of the image are missing. Please see attached image where the mouseover text is indicating a download option for the photo on the screen but no icon is present there. The only addon I have enabled is AdBlock Plus and this issue persists if I disable this addon. Plugins listed below.

Neither my computer tech nor I can locate a vertical scroll bar to view more than the first 5 email appearing on the screen of my web mail. He tried Google Chrome as an alternate and that works, but I really would like to use Firefox as my browser instead. Help! Frustrated

Hello folks, How can I turn on asking request about closure of any Tabs? I've changed ti "true" in the about:config (see attached). But it doesn't work (( Ver of FF is 43.0.4 Please, I need your help! Thank you!

Anything google related is not loading properly. The theme and several of the buttons do not show up in my gmail inbox. Google voice will not work either. Google drive tells me that I am working offline (when I am streaming music and using other sites). I would get in touch with google, but they seem to dodge direct help.

Newest version of Firefox crashes within seconds of opening a new window, using Windows 7 64bit. Crash ID: bp-2a127933-bb08-4107-835f-93aca2160120 Tried running in safe mode and get the exact same error, I have also submitted crash reports to Mozilla.

Dear Firefox Support,

I have just bought a new Lenovo Laptop with Windows 10. Everything is working perfectly (knocks on wood) but one thing has been bothering me. When I am using Firefox, I sometimes get a weird effect on my toolbar, or the whole top part of the screen. Sometimes even on the webpage, like it's not loading properly. I made a picture and added it in this message. I have tried setting the .exe as running as administrator and other settings and am quite good with computers (can bench test and build my own computer) but can't seem to solve this. All graphics drivers are of course up te date.

I also get a weird thing when opening my bookmarks, also made a picture of that and added it with this message.

Also, to add, I added the new tasbar skin so it would maybe help with the problem, it did not, so the cause is not the skin.

Maybe you know a quick solution to this problem?

Thank you very much in advance for the help.

Edit: I can't seem to upload the pictures through the website so I uploaded the to a website:
