Firefox 技術支援討論區

I have fixed (it's slow as **** on PC but works from my phone still), my printer which stopped working briefly, however I am unable to print pages in Firefox as even the preview window fails to load, changing browser doesn't work. I will try restarting Firefox but doubt it will work (restarting never has in the past).

Greetings,

Today, I went to access my Bookmarks, & found them "Empty", other wise "Missing"!

I found the "How to recover missing Bookmarks" topics, & that did bring back,what I consider to be My "Permanent Books", bu the section called "Other Bookmarks" will not come back, no matter how many times I go through the "Restore Bookmarks".

I Absolutely need that section to be restored, for I had many files in that section that I updated daily, that I planned to move to the "Bookmarks Section".

How can I get get this section restored?

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

Hello,

I am unable to play certain video on Firefox version 86 on my Macbook Pro 13-inch, 2017, running Big Sur 11.3 Beta (20E5196f), which I just updated my system to today. These sites are working in Safari I tried installing the previous Firefox version, version 85, these sites worked on this version! This problem only occurs on Netflix, Prime and Disney Plus. Other video sites like Youtube and Crave TV are working. This same problem occurred a few days ago, before I updated my computer, but I was able to resolve it by clearing cookies and cache in firefox, this no longer works.

On Netflix, preview videos that appear when hovering over a selection do play, but when trying to play an actual title I get error code f7121-1331 On Prime I get a message saying We're experiencing a problem playing this video. For assistance, please go to www.primevideo.com/help. On Disney Plus I get error code 83

I have tried on the advice of other posts to clear cache and cookies, disable all add-ons, checking if certain media options are enabled in About:config, restarting my computer and firefox, and resetting Firefox twice. None of these have worked for me.

The only thing that worked was installing and using the previous Firefox version 85.

Yesterday I was using Firefox normally (browsing, Discord, etc.). Today when I opened it, it wouldn't load any page. If I type something in the adress bar it will auto-complete or show suggestions based on google, but when I hit enter, nothing happens. It doesn't even try to load anything. I also can't go into options. When I click on the options button, nothing happens. I am not running in any compatibility modes. I have tried reinstalling Firefox, didn't help. I am not using any add-ons. I have done several virus searches. Other browsers work fine. I'm running out of ideas now, that's why I'm doing this post.

Since upgrading to a newer version of FF, I find that I am unable to save to PDF like I've been doing so for years. The MacOS User Guide says to choose File > Print then Click the PDF pop up menu and choose Save as PDF.

Well, this open is no longer showing up in FF version 86.0. Can someone tell me how to get it back? Thanks.

After firefox updated to 85.0 and added a new printer interface it will not print. everything else still prints fine and even when going back to the system dialog box it still will not print. It acts like it is going to print but nothing prints. I can save it to PDF and print okay but not to my printer directly.

Is it possible to view a list of all the things that were printed within the Firefox browser? I'm not interested in browsing history-- I'm specifically after an entire list of things that were printed using a printer within Firefox. I tried looking for threads asking the same question, but it seems like everything is focused around the normal browsing history. The system is MacOS Big Sur Version 11.2.1.

Unfortunately, allowing Firefox to update means we are now stuck with the new print dialogue, which is now as un-customizeable as all other browsers. The worst element of this from my point of view as a teacher who frequently prints from the internet is the newly imposed loss of the capacity to customize headers and footers. The two-pages-per-sheet option is obviously a good thing, but in order to number the pages, one is required to splay the URL across the entire top of the page. This is yet worse if you attempt to use the two-page-per-sheet format; you will now have the URL displayed TWICE across the top of the entire page. It's ugly and unnecessary, as is the date and time that I prepped the material. The title is at the top of any article; now it also have to be on every sheet multiple times, alongside the URL, the date and time, and only one possible numbering format. What is sad is that it appears not to be understood that the desired form for much printing from the internet is something approximating the appearance of a book or journal page; whether it is two on one page, or single pages per sheet. If anyone knows how to preserve BOTH the customizable headers and footers AND select one OR two pages per sheet, we'd be very well-helped.

I save many items and documents as PDF files using the Microsoft Print to PDF option, rather than physically printing on my printer. This worked fine for quite some time. This option no longer works when I am using Firefox, but it still works if I use Chrome.

I would rather not have to switch to Chrome whenever I want to print something to a PDF file.

How can I resolve this?

For some reason I have not been able to print from Firefox on Ubuntu.

It goes to the print queue but remains there - the Progress shows "Stopped"

I can print from word or any other program.

Firefox and Ubuntu are up to date.

I have tried resetting the printer settings and also reset the browser but no luck.

With Firefox 86.0.

In the preference page (about:preferences) we can specify default fonts, but the choices of fonts are not used when printing a web page if the page does not specify a font. (In my environment, although the default font is set to sans-serif, the serif font is used for printed pages.) Can we specify default fonts for printing? If not, I strongly think that Firefox should use the same font as the one for display (as long as the font is available for printing).

After the last update strange problem occours: when I print a web page in a normal A4 format, the printer prints a very little page, as a stamp, like an A8 format. I already tried to reset the printer settings in Firefox, but the same problem persists. What could be this strange inconvenience?

I was a Chrome user and recently shifted to Firefox. Everything is fine but I found out that when I want to merge 2 windows, I have to resize the upper window till the tabs of bottom one appear, so that I can drag and merge them into one. It's quite annoying sometimes especially when using a laptop with the touching pad. In Chrome, when I drag the upper window downward, the bottom one will show up then they can be merged just by a simple drag. Is there any extension or method to do this in Firefox?

OK. I use Buckeye Express as ISP. I have a Buckeye email address. There is a Buckeye URL address that allows me to see my email online. To sign out of my web buckeye account i go to a menu that has a Sign Out link. The address of the link is javascript:funSignout(). I can search the code on the webpage and find the link.

However when I click the link in the email program, the Sign out Window does not open in FireFox.

The sign out window has two buttons and a message: Do You Really Want to Sign Out? YES or NO. you have to click YES to sign out of my email address. I can get out of my email address by closing the FireFox Browser. Then I can go to the URL address and sign in to my email address again. If I do not close FireFox When I go back to Buckeye Mail, I am already signed in.

So the javascript window does not open in FireFox 86.0. If I use EDGE or CHROME, the window opens. I can click YES and sign out. I have enabled popup windows but the popup is generated by javascript on the website. But the window doesn't open. This is a relatively new problem. Firefox 86 (64 bit). Help
