Firefox 技術支援討論區

I'm currently using KDE Plasma on Archlinux and Firefox windows are very laggy when maximized. I have a 4K screen and running Firefox at full 4K causes scrolling to be very choppy and makes YouTube almost unresponsive. If I make the window smaller (about a quarter of the screen or the size of typical 1080p), it speeds up and works normally. I've tried the nightly build, Icecat, and Waterfox and none of them have made any difference.

I use a AMD Radeon R9 Fury X GPU and have the latest version of xf86-video-amdgpu installed and have hardware acceleration enabled in Firefox settings.

EDIT: I've now tried Firefox in Cinnamon Desktop as well as KDE Plasma and they are both equally laggy.

When I search for something on the internet using Firefox, Bing most times comes up as the search engine and I'm trying to get rid of Bing as a search engine. I have changed the 'Search' preferences in Firefox but Bing still shows up?

The warning message is appearing more frequently and seriously affects my use of the computer. Clicking on 'Stop it or Wait' removes the message but it comes back sometimes in only a few seonds.

Hello. I'm very upset about your latest updates. I understand that you care about security and increase the requirements for sites. But not in all cases it is convenient for users! Why autocomplete of login and password for sites without SSL doesn't work??? Because of this, I have serious difficulties at work and at home, because I do not remember logins and passwords and I have to constantly go into settings, look for saved logins and passwords there and enter them manually !!!

At work, various web services are used within our company, not all of them work on SSL. Logins and passwords I had previously been saved to them, but yesterday the autocomplete of the login and password stopped working. Previously, it worked, although it issued a warning that the site is unsafe, and now does not work at all.

You should add to about: config the ability to constantly use autocomplete logins and passwords without restrictions, even for http sites, even for https.

Color Laser Printer; Canon LBP7660C, UFR II driver.

Windows 10 version 1607, build 14393.1066 (& the 5 or 6 prior to that)

Firefox v53.0 (& about the dozen before that).

ONLY Firefox, ALL other Windows 10 applications print correctly.

Have attempted all of the work arounds and suggestions, removing, reinstalling, totally purging all of Firefox, etc.

1) Ignores which tray to draw paper or envelopes from; always only wants the manual feed tray

2) Incorrectly scales printed objects & pages. For example, a return label from Amazon is printed about 1/4 the actual size. A web page is between 1/3 to 1/5 its actual size. An airline boarding pass (United, American, & Delta) is about 1//4 the correct size.

3) Ignores all graphics scale setting in the printer driver setup

4) Ignores settings for color/black & white/grayscale

5) Ignores settings for printing on one or two sides, always only prints on one side

And several more printing related issues.

Also incorrectly scales anything printed to Adobe Acrobat X, when opened & printed through Firefox, when opened from Acrobat directly, prints correctly.

ONLY Firefox. No other application has any of these issues.

Any help appreciated.

Thanks

My bookmarks used to be dated in the UK/en style (day/month/year), but now they are in the US style (month/day/year). It is very confusing for me and I can't find any way to revert them to the UK style. I think this happened from the time of the last update, but am not certain. I use a Mac, Firefox version 52.0.2 (64-bit) and the language chosen is English (en). I cannot believe there isn't a way of changing this setting so would be grateful for any help. Many thanks

Firefox seems to have been updated and the very useful facility on New Tab of 'tiles' of useful web sites has been replaced by New Tab by Yahoo with only a few round button for a few websites. How can I get back New Tab with the web site tiles?

The message is sent form Windows 10 from Goggle. Subject is New sign-in from Firefox on Windows. The message is the Your Goggle Account bellbill1101@gmail.com was just used to sign in from Firefox on Windows. What does this mean? I received this message when I signed into my Asus tablet.

Thank you Bill Bell

I have Firefox installed on four devices (two desktops, one laptop, one Android phone). By the way, the two desktops and phone are synced together and have all the current information.

My main desktop computer has all of the bookmarks, passwords, etc that I want to sync to the other devices. I forgot my Firefox Sync password so from my laptop I reset it and synced. All of the bookmarks, etc, on the laptop synced to FIrefox on the secondary desktop , which is incorrect. I needed the laptop to sync with the data from the other devices.

As it stands now my laptop and secondary desktop have the incorrect sync data, using a new password. My main desktop and my phone have the correct data to sync, but using the previous password.

What do I need to do so that bookmarks, etc, on my main desktop is 'master' and pushes out it's bookmarks/passwords, etc out to the other devices? The three computers are using Firefox 52.02.2 (32-bit) on Windows 7 Professional. I don't know how to identify the version of Firefox on my Android device.

Thank you in advance for your assistance!

I am running Firefox 52.0.2 under Windows 10 Pro. The PC has two user accounts, and Norton Security, Trusteer Rapport (and others!)

Up until a few days ago, everything was fine. A classic case of nothing had changed and then ….

I had a problem with the Rapport icon "going missing" on the standard user account, and checked the admin account where Firefox didn't launch.

After looking at the wealth of info/FAQ on this website (and trying lots of the options) I am in the position where after reinstalling Firefox (and deleting the profiles etc) it now stalls with “connecting” showing when first launched immediately after installation. If you then go to trouble shooting and Refresh Firefox it then works fine, and any other instances of Firefox launched with the first instance still open also work fine.

However, once these instances are all closed, when you next launch Firefox, it’s back to stalling with the timer going ad infinitum and showing “Connecting”. The close doesn’t work and you have to use the Menu Exit to close Firefox.

I have at various stages, and in multiple instances, uninstalled and reinstalled Firefox, having removed the two accounts profiles, and tried many combinations of restarting in Safe Mode with add-ons disabled (stalls) and Refresh ….. the latter being the only time it works.

Looking at the settings after Refresh, there are no active Extensions - just Logitech SetPoint and Norton Security Toolbar, both of which are disabled. The plug-ins I guess are required by Firefox being Shockwave Flash, Widevine Content Decryption and OpenH264 Video Codec. Appearance is the default theme. Opening the Profile Folder from the Troubleshooting page, shows no Extensions folder.

It’s very frustrating and even worse, although I am a massive fan of Firefox, I’ve had to install Chrome to continue working!

I’m really confused as to what changes between closing the “Refreshed” Firefox, which has set up a new profile, and then ten seconds later starting Firefox and it doesn’t work.

Any help would be much appreciated, as I am far from an expert on this!!! ..... and I want to uninstall Chrome at the earliest opportunity. Many thanks.

In updated Firefox there is no chain-link icon for creating a tiny url for the current site being viewed. How does one create a tiny url now?

edited email from public and search/spam bots as nobody here does support by email.

Hello, I am a new user of Firefox, I switched from Chrome. I am having problems loading certain pages that work on other browsers. Almost all the web pages I go to work fine, however Youtube and Amazon are the two biggest ones that have been giving me problems. When I type in the address, (I have also tried going in through a search engine) I get a page full of what I can only describe as "Wingdings." I have posted a picture to show. Needless to say it is very frustrating. I disabled my security, confirmed its allowed on the firewall, removed and re-installed Java. Kind of at my wits end and hope someone can help.

Using Windows 10, Adobe Flash 25 NPAPI v 25.0.0.148, Firefox 52.0.2 & 52.1.0, (Do I need both?), Mozilla Maintenance Service 25.1.0.6316, Shockwave Flash 25.0 r0 plugin, Silverlight 5.1.50906.0 plugin.

I am unable to save my user name and password for Ebay's website. No problems saving for other sites.

https://community.cartalk.com reports 'Powered by Discourse, best viewed with JavaScript enabled' and doesn't work properly. So I use Opera for that. I know about npapi plugins being obsoleted. Why isn't Firefox's web API picking up?

I have a iMac and on version 10.12.4. Have used Firefox for years and when it said need to update notice that it was not just Firefox but Firefox ESR version 52.0.2. I can tell you I have no reason to use the ESR version plus not smart enough to put it on my computer. How do I get back to the basic Firefox?

I tried all possible emails associated with my old acct. Said they wound send email to them . Nothing. Does the thief that stole my laptop have to sign out first? This is nuts. In the meantime I did create a new acct but sign out before trying the email verification page (send info to those addresses).
