Firefox 技術支援討論區

I have the Firefox in both my PC and laptop. Both my PC and laptop have dual boot Windows 10 and Ubuntu 20.04 with the latest updates. Firefox is in version 87 also fully updated in both OS in both machines. When I try to download anything whatever the size of the file is I see the little that shows downloading has started and then it vanishes and shows that the download has failed. I've already tried cleaning the cache, the history and the downloads history but nothing worked in any of my systems. Can anyone please help?

When I try to upload something to youtube music it keeps on showing up as an error despite being the right file extension. To test this I uploaded the same files on Chrome and they worked perfectly.

Problem was fixed upon fresh start /or resetting cookies and cache but both are annoying each time as I have to relog into everything each time this error happens.

Respected Teams,

Whenever I opened just 5 or new tab in Mozilla Firefox, then My PC starting stuck issue, However MY PC has 16 GB DDR4 RAM, 120 SSD, Core i9-7th Gen,

further in CORE i7-7th Gen Laptop, we faced no issue at all if I opened more the 10 Tabs at a time, No Fans speed increase no stuck or hang issue, why this is happening only with My desktop PC?

Thanks in Advanced!

Hello, I use 2 monitors if one of them has a live stream from Facebook then there are such flashes on the primary monitor while browsing. But only if Firefox is open on the primary monitor. Here is a video of the flickering: https://www.youtube.com/watch?v=AOsjhbInuQQ I had a system reinstall due to an SSD replacement, but the error persists. This error has occurred since the Windows 10 Pro 20H2 update. I have an RTX2070 card with the latest gpu driver.

Thanks for the help!

Firefox 87.0 / MacOS, in safe mode, with and without enhanced protection. Mostly after clearing cache. Server is Apache, running WordPress.

Other browsers (Chrome, Opera, IE) have no problems.

Using HTTPS.

Page itself (HTML) loads correctly. The referenced (linked) files do not load, even though they are on the same server.

When I look at the Network Analysis tab, I see that the CSS and JSS files have no return codes, and show 0 Bytes transferred. It does not show the data coming from the cache. A detailed look at the request looks normal, the answer is not available. When I resend the request I get an answer, no problem.

No messages in the console.

It seems to have something to do with the server, when I deactivate certain WP plugins, the problem disappears. Perhaps the problem is worse when the server is slow... cannot prove this.

I am looking for what I can do on the Apache side to fix the problem.

Thanks in advance, Ron

I have a specific problem...Firefox will not load a particular web site which it previously did for years. I have refreshed and reinstalled with no solution.

Here is my story (nightmare)... When I try to launch my credit union, Navy Federal, the following appears on my screen.

Access Denied You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/nfcu.fcc" on this server. Reference #18.859ec817.1618087497.20456bf6

I can launch other web sites with Firefox AND i can launch Navy Federal with other browsers. On subsequent attempts to launch Navy FCU, I always get the same Access Denied message, however, the Reference # changes. THANK YOU!!

I keep getting a message that a web page is slowing my browser down. And it is terribly slow. How can I get rid of this frustrating issue? I think I even know the web page that it is.

My tabs are frequently crashing and some strange behaviors occur with firefox after these crashes (adblock failing to work until browser restart, browser going blank for a split second). My browser also occasionally crashes, and even more infrequently my entire computer will crash which usually happens after series of tabs crashing in a row. It may be a ram issue but I have no problems with any other programs on my computer so I doubt that.

Some sites are not loading like instagram and for some sites browser doesnt even try it directy shows connection problem and only loadds the page after reloading the site many times

web pages don't display but address is shown at tabs, can't see options but other menu options seem to be okay. I uninstalled and erased all related data (I could find) multiple times and reinstalled multiple times but problem remains. I tried refresh, safe mode, etc. At installation I get error VCRUNTIME140_1.dll not found, a susequent installation finishes without errors. I am sending this from another system because I can't use the problem unit for this post. The problem system is similar to this one. I am puzzled and seek help.

Somewhat recently, when editing text in any text field in Firefox (87.0 64 bit), I noticed the arrow keys don't repeat when held down. Other keys do just fine, but the arrow keys, when held down, move one position, there's a very slight delay, and it moves one more position and then stops; no auto-repeating. I've restarted Firefox without addons and that didn't help. I've also toggled the Auto-scrolling and smooth scrolling options too.

This makes editing long text fields a real pain. I don't see this problem in any PC-based apps and arrows keys do repeat OK in Chrome and Edge. It appears to be a Firefox issue.

Any ideas? Many thanks!!!!!

All the family use my PC with their own user accounts. Frequently Firefox goes slow and whenever I check 'About Firefox' I see 'Firefox is being updated by another instance'. This means that I have to log off all other users and then let my Firefox run an update check which, of course, normally just comes back with 'up to date'.

The problems are normally evidenced by Firefox just being very slow and/or only showing parts of the page and those parts changing as and when the page is scrolled.

This is a real problem with Firefox and makes it very unpopular with my family due to its unreliability.

Could not Firefox be set to only do an update check when it can actually complete the check and/or update.

Any advice appreciated.,

thanks,

Rob

I am using a HP Envyx360. When I'm in tab mode the keyboard pops up and than closes suddenly. This only happens for Firefox when I try to type on the address bar or type in any website. It doesn't happen in any other application. If I'm out of tab mode it works fine.

Recently, a kind volunteer helped me resolve a technical problem I was having with eBay. I have only one start up on my computer now, which is my VPN I have disabled all my Add-ons. I exited out of Firefox, restarted my computer and went directly to ebay and had no trouble signing in or using the site. Yay! I thought it was all fixed. I still wanted to use some very important (to me) add-ons like Ghosterly, and a couple others, which I have had for approximately a year with no problem on ebay. I enable 3 of my favorite addons. I went back to ebay. And, now I can't sign in. They say the password doesn't match. I know that it is correct because I have it written down. When I tried many times, they kept making be "bot verify" When I tried to reset my password, they said I had to chat with someone. I am unable to chat because they say I might have disabled java script. I don't know where to look to see it I have done that. Having a "Senior Moment" here............

....also starting to get frustrated........... grrrrrrr..... I wanted to try to turn on one addon at a time, to see which might be the troublemaker, but never got the chance.

Any thoughts??

I have entered the website i wish to use and logged in all goes well until i try to open my webcam and go live. i have a webcam its always worked but its now saying to me Chat server authentication failed please contact us. Im confused it always worked
