Форум поддержки Firefox

Hi all,

I've been having this issue for a few days now, I've tried to uninstall, re-scan, reboot my pc and reinstall Firefox but they still PERSIST!! Every time I open firefox for the first time after turning on my pc, Avast pops up with the malware warnings. I've used Avast, Malwarebytes and AdwCleaner but nothing seems to be working. I've disabled and uninstalled the ad-ons as well.

I'm not sure how else to remove the malwares because it seems to be running from "C:\Program Files\Mozilla Firefox\firefox.exe".

Please help.

When I try to print from Firefox 88 on my Mac Laptop running OSX 10.12.6 the new print preview window takes a very long time to load the preview before I can print. I could not find a work around.

I tried switching to the Classic print system via (print.tab_modal.enabled - False) Now I don't have the preview to deal with so I can print immediately like I used to. However, if I try to open a PDF in Preview from the Print Dialog window, it takes a very long time to load the preview which it did not do in earlier versions of Firefox.

I am surmising that one of the Firefox updates added the print preview function which doesn't work quite right on my Mac.

Any ideas would be appreciated. Andy

Hi,

I have decided to ditch Google as much as possible, and come back to Firefox. I always had a tinge of guilt for going over to Google, but that's another story.

The page load times for Chrome are averaging about 1 second. for Firefox they are between 10 and 40 seconds.

OOB does Firefox need any setting changes to make it load pages faster ? I've compared page loads on pages I havent visited before, so no browser cache settings should affect loading times.

Here is some data to back this up.

System : OS Windows 10 Pro - Version 10.0.19043 Build 19043 All latest updates as of 20 April 2021

HW AMD Ryzen 9 3900x CPU X570 Aorus Motherboard 64GB DDR4 3200MHz 3090 Nvidia RTX GPU All PCIe Gen 4 NVMe SSDs

Firefox : 88.0 (64-bit) - About Box says "Up to Date" Chrome : Version 89.0.4389.114 (Official Build) (64-bit) - latest on stable channel

3 x Arbitrary URLs to load a. https://calgary.ctvnews.ca/alberta-doctors-find-2nd-case-of-blood-clot-linked-to-astrazeneca-vaccine-in-canada-1.5391531 b. https://www.bbc.com/ c. https://www.usa.gov/

Clear Cache before going to web site Choose web sites I had not visited before on this computer

Load times for Chrome in MILLI seconds a 1178(ms) b 1321(ms) c 914(ms)

Same pages loaded in Firefox in SECONDS a 40.65 seconds b 10.38 seconds c 8.33 seconds

Ping and Internet Connection settings Ping 2ms Download 854.16 Mbps Upload 821.35 Mbps

Both browsers have no plugins loaded (except the page time load plugin).

Even if the plugin is telling me the wrong times, I can tell that the times are roughly correct by watching the page load, ie Chrome takes about a second to load most pages, Firefox is taking about 10-40 seconds.

I presume I must have some kind of setting that's wrong somewhere, but this is OOB, so are other people experiencing this kind of latency ?

Thanks

doers mozilla produce a version of firefox that doesnt crash every 5 or 6 minutes if so i would love to install it as your latest offering has destroyed all my bookmarks passwords and just about everything else not just on the 32 bit pc but also on the 64 bit

Following other support threads, I managed to turn off the incredibly annoying yellow bar warning of "a script slowing down the browser". But Firefox then defaulted to displaying those messages as they occur in separate error message dialog boxes.

Again, following other threads, I have managed to make a decent amount of them not display by increasing the time Firefox waits before popping up the error message. I have also determined (from looking at the script name that displays in the error box) that the remaining scripts originate at whatever site I am browsing at the time, so at least my very few add-ons are not to blame.  :)

I probably can live with those remaining few, except that if a script fails and I happen to be in another tab when that happens, Firefox annoyingly switches focus to that tab. It becomes even more of a nuisance if I was typing in the tab Firefox switched away from.

Is there a setting in about:config that will prevent Firefox from displaying an error message unless and until the user has selected that tab his/herself for focus? (Or if not, could the developers code that into a future release?)

Good morning everyone, for at least 6 months now I'm having a lot of problems viewing some sites with Firefox. I have not been able to find common points between these sites, I only noticed that many are made in Wordpress.

Anyway when I load these sites Firefox takes 3 to 5 minutes to display them. Sometimes the screen is white, other times the wheel turns. Any other browser, of course, plays the same sites immediately.

To complicate things I have to add that the same sites sometimes start loading normally again, and then stop loading. But not all of them. I mean that one starts working again, another one continues not to work and vice versa.

I've done dozens of tests without being able to solve the problem in any way. I list them:

1. Deactivated all the extensions, even uninstalled, loaded Firefox in safe mode and nothing to do. 2. Uninstalled Firefox completely (cleaning %appdata%, windows registry and program folders) and reinstalled clean, no go. 3. Installed various versions of Firefox Developer, 32 bit, ESR, normal, even portable, always without extensions and with standard configuration and nothing to do. 4. Unplugged the network cable and connected in thetering / wifi with the 4G of the cell phone and nothing to do. 5. Tried a neighbor's wifi and nothing to do. 6. Wiped the pc, registry, uninstalled any software that wasn't absolutely necessary and nothing to do. 7. Started Windows in safe mode and nothing to do. 8. Uninstalled Eset Antivirus (I have a friend who has the same antivirus anyway and he can see any site perfectly with Firefox), deactivated Windows Defender as well and nothing to do. 9. I've followed the advice of dozens of articles modifying about:config in various ways (always making a backup first) and nothing to do. 10. Checked the pc with 4 different antivirus, antirootkit, antimalware and it was perfectly clean.

At this point I don't know what to do except give up using Firefox after a decade, because the problem seems to increase, in the sense that the sites that I can't load are more and more.

If someone can help me to avoid it I am very grateful...

Since the update 78.10.0 yesterday I can't play Netflix or open facebook or messenger. Facebook only shows the first post and I cannot click on anything. Messenger is a blank page Netflix shows error NSES UHX which Netflix support says does not exist in their system

In Mac OS, when the locale is right-to-left, the window control buttons should appear in the top-right side of the window. In case of tabbed window it should show before tabs. That is not the case here in Mozilla products. They show to the left in a malformed way. Only the close button is clickable, the Minimize button is barely visible and the Zoom button is totally hidden off-canvas. (Please see attached screenshot).

Today on my Netflix I received a "widevineCDM plugin has crashed" message. I went to the plugins and everything is updated even my FireFox. I have uninstalled and re-installed this app, but nothing has helped. Not sure what else to do. Any suggestions would be helpful. Thank you in advance.

I typed www.netflix.com in the address line and Netflix tried to come up. But I got a huge black page with an error message.

 Error Code F7702-1003 

At the top of the page in a thin yellow box it says

 The WidevineCdm plug-in has crashed. 

It suggested that I reload the page and the plug-in would reset itself. I did but it didn't.

How do I fix this problem?

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!!!!!

Suddenly as of the last update to FireFox 88.0, the embedded screen capture function disappeared. I use it a LOT... I will have to go back to previous version of FireFox.

So for a few weeks now I've had this problem come up multiple times. I notice that the browser is slowly getting more and more unresponsive while switching tabs and eventually it stops completely. I get a loading symbol in the middle of the tab, even on previously loaded ones. I can't switch tabs anymore, but I can open a new tab once per Firefox. I can open as many windows as I want, they all just show a white page and the search bar is unclickable.

I don't get any error message from my computer nor Firefox. Restarting the computer (because I don't want to lose my tabs) solves the issue and it becomes perfectly responsive again, but it takes ~2 minutes to shut down, when it usually takes at most 20 seconds, because Firefox is not closing properly.

I also didn't add any new add-ons before the issue started appearing.

Now I wouldn't mind a restart here and there if I wasn't working as much as I do in the browser. So if anyone has an idea where to look for a solution I'd very much appreciate it.

Hello If I open Firefox on my Smartphone it shows me blank site,see added screenshot. I did uninstall it already and new installation but still the same.This happen since this morning.

Sorry my english i am german

Why is every new Firefox update nothing but a buggy piece of crap? Newest Firefox crashes every 3 attempts to do something, basically unusable. Thanks for the quality programming.

Raspberry Pi 4B Raspberry Pi OS -- Fully updated OS. Firefox 78.9.0esr (32-bit) -- Latest and greatest for Raspberry Pi OS.

Some videos I am getting no sound. I try the effected videos in Chromium for Raspberry Pi OS and it works fine. I read about a possible fix and tried disabling hardware acceleration with no effect. I also blew out all the cookies,. history and stored site data. Each attempt closing and reopening Firefox. Same thing on the same videos, no sound in Firefox but fine in Chromium.

Any tips or pointers?

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.
