Firefox 技術支援討論區

When I have my computer plugged into an external monitor, I want new browser windows to open on the external monitor, but they always open on the computer's monitor. I have gone through the entire process at https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems (clearing cache etc., trying safe mode, creating a new profile, refreshing Firefox, reinstalling Firefox) and the problem persists. This happens if I manually select "New Tab," "New Window," or "New Private Window" from the File menu with no existing windows open. It also happens if I use the key commands for any of these menu items. It happens if I use the menu bar on the computer's monitor or the menu bar on the external monitor. Opening a window and dragging it from the computer's monitor to the external monitor does not change anything. I've also tried using Divvy (https://mizage.com/divvy/) to move the browser window between windows with a key command, but after moving it this way nothing changes—new windows continue to open on the computer's monitor. How do I set which monitor Firefox will use for displaying new windows and/or get it to remember my preference?

I used to use Firefox but changed to Waterfox Classic a couple of years ago. I have now downloaded Waterfox Current but can't transfer my bookmarks and passwords to the new Waterfox. All the suggestions on the sub-Reddit group do not work because I am not sufficiently computer literate to understand them and/or they are incorrect. Syncing did nothing so I am back on Firefox but syncing here does not bring all the bookmarks from Waterfox Classic to Firefox either. As noted, I am to all intents and purposes computer illiterate plus I am in my mid-seventies with no teenagers around to solve techie problems for me. I really don't want to have to open my bookmarked sites in Firefox and them bookmark them manually, so is there an easy way to get my bookmarks and passwords from Waterfox Classic to Firefox. If so, can someone point me in the direction of an idiot's guide so I can revert to Firefox as my default browser? Thank you

Firefox does not appear in volume mixer in Windows 10. No sound is audible in Firefox. The same Web sites work well and produce audio in other browsers. Everything's OK with PC audio system.

I currently have version 72.0.2 and it is so slow.

I suspected an ISP problem although I have fibre optics but I just have to compare FIreFox with another browser to see that FireFox is the problem.

For instance, on the same site, I can call up a different page in around 5 seconds with FireFox whereas the same change of page takes well under 2 seconds with the Avast Browser.

Opening 3 tabs simultaneously in FireFox when I launch it takes YONKS whereas it used to load all 3 pages in a blink.

I already have add ons like "Disable HTML5 Autoplay" installed to speed up things.

What is the solution please?

Windows 10 64 bit, Firefox 7.0.2 After I log into an Etrade account, if I click on any link (such as a stock symbol) within the account, I am returned to the Etrade login page. If I use the back button on the browser I am returned to the page I was on (I was not logged out). I never can get to the stock symbol or other link within Etrade. I have tried changing every add on or extension change (especially security settings), refreshing Firefox, running in safe mode and actually reinstalling Firefox without success. I think I have seen this on other websites also, but this type action does not happen on all websites. This does not happen when using Chrome.

Upon sysytem startup today my browser immediately opened up a browser which then filled up with multiple tabs all labelled Error. IT then kept on opening up new browser pages which likewise filled up with multiple tabs all labelled as Error. Eventually a crash dialogue popped up and having sent that I tried to close the browsers only for them to continue popping up. Eventually I was forced to restart the system. Happily upon restart the problem did not recur. My anti-virus (Bullguard) reported no issues.

I was learning HTML and CSS basics on CodeHS. At CSS basics style tag was not working correctly. CodeHS was thinking that there is no style tag, however on Chrome browser it was working correctly.

Okay, so before, when I loaded up 100+ Youtube videos, they stayed when switching tabs - no autoplay. Suddenly they decide to autoplay when switching tabs - note, I've not done anything to my settings or plugins. Fair enough, maybe you changed something (which you often do, without informing). So I check the options. It was on "Block audio", which obviously didn't work, so I tried "Block Audio and Video" - which WORKS, but now both the video is paused (which I want) AND the audio is set to mute (which I DON'T want) - so... what does it take to have Youtube wait for a click to start playing a video loaded in a background tab, but KEEP AUDIO ACTIVE, so I don't also have to unmute the damn video?

I've got Firefox 72.0.2 on two systems, one old (10,000+ history items) and one new (200 history items). Both are logged in with the same Firefox account. I've enabled history sync on both and clicked "Sync Now".

The new Firefox install is not getting, at any usable rate, the history from the old Firefox install.

What I've already tried:

1. Log out of my Firefox account on both systems and log in again on both systems. 2. Restart both systems. 3. Disconnect & reconnect from their network connections (obviously, both are browsing the internet just fine) 4. Repeatedly click "Sync Now" in Firefox Options.

System Details:

1. Both are Firefox 72.0.2 and Windows 10 x64 1909 (build 18363) 2. Both are connected to high-speed internet (100 Mbps download / 10 Mbps upload) 3. Both have zero extensions enabled except Bitwarden (password manager).

What is wrong with Firefox Sync here and why is it not syncing any data?

I read the recommended articles for this problem on the Firefox website and deleted the files: Delete the following files: extensions.sqlite , extensions.sqlite-journal , extensions.ini , extensions.json and Restarted Firefox. That didn't work. I also turned everything in Bitdefender off and tried to install the update, but that didn't work either. The Notice says: Firefox update Important Firefox update available. Click "Install" to continue. Program firefox.exe Verified Publisher: Flash Player Necessary measures: Now click on “Continue to Installation ” and then on “Add” to complete the process. See attached screeshot When I click on Install a window comes up that says: "Allow newsoftware-update.com to install an add-on?" When I click on "Continue to Installation" the window that says "The add-on could not be downloaded because of a connection failure" appears. See attached screenshot. So far I have not been able to get past that. Please help. Thanks

In the Search panel of the Preferences page I have changed my preferred search engine to DuckDuckGo. It will stay as this until I quit and reopen Firefox, when it reverts back to Google. I've tried this a few times but it always goes back. I've looked for a cookie that might be being deleted, but there are none on my machine (that I can see).

I'm running Firefox 72.0.2 on a Mac with Catalina 10.15.2 and also have Firefox apps on an iPhone and iPad.

Can anyone shed any light? Thanks in advance

In Firefox on my Mac, I frequently click on the Page Actions ("three little dots") at the end of the URL bar, and then from the options that pop up, click on "Share" that takes me to the Mac Share Sheet options (Air Drop, Messages, Mail, etc.)

In Mac System Preferences for the keyboard, you can create keyboard shortcuts for any application, and I'd like to create one for this action in Firefox. I just need to know the menu pathway. For example, in Safari, it is "File->Share->[Air Drop, Messages, Mail, etc.]"

I cannot find/figure out the menu pathway in Firefox for the Mac Share Sheet. Can anyone help??

I've added screenshots of: 1) Accessing the Share Sheet in Firefox via the "three little dots" in the URL bar 2) The Mac System Preferences Keyboard Shortcuts creation window showing the menu pathway title I'm needing to figure out 3) The Share Sheet menu pathway in Safari for comparison/reference

TIA!

The "Ask to save logins and passwords for websites" setting is cleared every time I restart FF. This needs to be the first item to change when I start FF. Any ideas about how to make this 'sticky'?

Incognito, opened a newspaper page, then my medical site to see abt apt, then walmart took over my entire page not a little ad, the entire page. This happened twice. I cleared my cache, but I was and always am incognito. Why is this happening. I feel like restarting my computer from factory at this point I do not want anything taking over my page.

When i browse to a web page with a username and password, firefox displays a drop-down list with saved usernames, this list includes saved usernames and passwords from a number of other sites. these sites are all for the same domain, but not the same site.

How do i limit the list to only include saved passwords from the current host.

for example, if I am on site http://www.example.com, the saved passwords lists entries for http://admin.example.com , http://portal.example.com , ...

For the last several days McAfee has blocked the following IP address 52.216.241.14 as being suspicious. When I Google searched this IP address FF lit up with a red warning message. What's up with this address? Also, is there a better forum to get more information about this address? Thanks

I've read many support posts. I cannot find a solution that works. This does not happen on Chrome nor Safari. I have turned off all findable Arial duplicates in Extensis, etc. I just have no idea where this occurs and I want/need Firefox for my default browser while I run development sites with grid and use Firefoxes Inspector tool.

Firefox does not display banners in youtube videos or flash games and instead shows yellow fields with a red font. Everything works in MS Edge. Flash Player is correctly installed.
