Firefox 技術支援討論區

Hello - I've been looking around the Firefox site, and the Internet in general, and so far haven't found out the answer to my question: how do I get Firefox 104 to work on my Linux Mint 18.2 Cinnamon Sonya 32 bit? Specifically what I haven't been able to determine is whether or not I first need to upgrade my Linux, which I suspect. And if so, what's the minimum level of the OS that is required? I may be overlooking the simple answers, but so far I cannot find them. And so far the Firefox website upgrade feature does nothing that I can detect. Thank you for any assistance - Doug.

even when disabled my background colour keeps reverting to black in firefox I have disbled dark option in themes but it still reverts. I have set text to black and background to white.

Tried to use doxy for a video call. Said I needed to refresh to load most updated browser. Once I did that, it says doxy has no access to webcam. I cannot figure out how to change that.

Thanks

Hey there,

How can I change the css of pages created by an addon?

(Example-URL: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html)

I know how to change normal pages css via different tools like Stylus etc. (or via userContent.css). But this does not work for pages created by addons.

Can you please help me?

Webpages saved as PDFs using FF are very large files compared to the same webpage saved as a PDF using Safari. FF will create a 2-3 page pdf that is over 3 MB of data, while Safari saves the same pdf as 325KB. I never noticed this to be the case in the distant past but as my available storage space started shrinking rapidly on my MacBook I realized this might be the culprit.

I don't know when these large pdfs files started with FF but as I reviewed some similar files from several years ago, the same type of 2-3 page pdf in FF was in the KB, not MB of data. Can anyone help me understand why this is happening? Is there a setting that should be changed so these pdfs are not so bloated in size?

I am still using FF 88.0.1 having not made the leap to the newer versions of FF because of all the bad reviews. That said, I have not seen any info which indicates that FF scaled down pdf file sizes in the newer versions of FF.

In FF's Preferences pane PDFs are set to open in FF. Would it help reduce the file sizes if I changed that so they open in Mac's default application which I assume is Preview? I don't know if that's what the default preference was years ago when FF pdfs were much smaller files, or if changing that would make no difference at all.

Also, for what it's worth, I previously disabled FF's new-ish Print Preview Interface in about:config because it was consistently overriding the preset positions I set for my headers and footers, resulting in them being cut off the printed pages, however, the bloated pdfs were a problem long before FF introduced the Print Preview Interface feature.

Any suggestions on how to reduce the size of pdfs that FF is creating? I don't have and don't want to get a 3rd party application like Adobe Acrobat to deal with this, when I can simply use Safari as my browser. Thank you.

Hi, none of the videos appear/play on this CNN site that is all about videos. Only still shots appear. The videos play in Chrome. Here is the site: https://www.cnn.com/2021/04/23/world/videos-of-the-week-mobile-april-23/index.html

I've already tried toggling the "Enhanced Protection" switch off and on to no effect. I don't see any option for enabling/disabling permissions for audio/video in the address bar as appear on other sites offering video or audio. Thanks for any remedies.

Hi, lately I have been trying to tackle my secondary HDD being spun up for no reason in the background and one thing that keeps popping up is Firefox.exe accessing a bunch of fonts contained in the Solidworks installation on the HDD (which is a secondary drive, while Firefox is installed on the primary SSD).

I really cannot understand why it happens, since I think nobody is supposed to install Solidworks along with Firefox. Of course I don't want this activity to wake up my drive, but also, is it normal? I have to admit I'm kinda worried.

I'll attach screenshots from Sysinternals Process Monitor

Thanks in advance to anyone that will help :)

Dear, I always have a lot of tabs opened and I guess I had one too many opened yesterday. Already I had to recover my settings after a crash the day before. So I had the crash and restarted the pc yesterday evening. All my tabs were gone, so I shut down the pc and started up again this morning and still no sign of restart or nothing of my tabs, history, all my Linux worksheets were completely empty accept for this page... I went to settings to restart the previous settings but it always does that automatically, and it only started the one I was in this morning (the empty one) I tried for a crash rapport but could not find one. How do I get everything back, please ?! I need to get the tabs back before this previous session! Please help... Where can I find them? What can I do? I can't have lost them all ... I will go nuts .. Please help me! My system is a Linux Mint 21.0 version, I think Thank you so much! Nadine

In the latest version (99.0 for 64-bit Windows), the "Send Page to Device" and "Send Tab to Device" commands in the right-click menus are gone. They were available up to at least 88.0.1. Where did they go?

The attached screen shots are: - Right Click Menu on Page -- 88.0.1 - Right Click Menu on Tab -- 88.0.1 - Right Click Menu on Page -- 99.0 - Right Click Menu on Tab -- 99.0

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

I'm so unhappy now I don't know where to begin.

I was having trouble loading a website (lowes.com), continually getting an "access denied" error message. It occurred to me that I'd read somewhere that if you told Firefox to "forget this site," it might solve the "access denied" problem. I didn't remember how to do this, though, so I searched online and found a site that said that adding the "Remove" button to the Toolbar and clicking it would solve the problem. I dutifully added the "Remove" button, then, before clicking it, I triple-checked that the "Forget the last Five minutes" was selected and not any longer period of time. After all, I didn't want to lose everything!

Well, I did.

I had literally hundreds of tabs that I was working on open — they're all gone. All of my history — years worth — is missing. More things may have been deleted, but, to be honest, I'm afraid to check.

What did I do wrong? Or is the "Remove" button buggy?

And while I believe that everything that's missing now is irretrievably lost, if anyone has a hack to recover anything, I would be so, so grateful if you'd let me know.

Thanks in advance.

P.S. I wrote this post up once, hit "Submit," then, after an interminable period of time, the screen went to a blank page. My original post has never appeared. Is there perhaps something wrong with my Firefox (which has been perfectly fine up until now)?

I have hit what appears to be a "YouTube TV" (vs YouTube) buffering problem. It happens only with Firefox on my PCs. After a few seconds to a minute of playing a TV program or movie, the video/audio stops with a spinning arrow. If I previously had turned on "stats for nerds" to monitor this, I can see when network activity stops and the buffer then eventually gets exhausted.

This does NOT happen when running YouTube TV on my TVs or on my iPhone. Probably more significant, it does NOT happen with YouTube TV under either Microsoft Edge or Google Chrome on these PCs. If I run Firefox in Troubleshoot Mode, i.e., no add-ons, extensions, etc., the problem still exists, so it is not just some rogue add-on, but is related to Firefox itself. The problem appears to be only for "YouTube TV" on Firefox since, for example, videos played from YouTube (vs "YouTube TV") do not have the problem under Firefox.

I tried rebooting my router as well as the PCs. The problem still existed. The PCs are high speed and the internet connection is fiber optic. One of the PCs is connected by Ethernet; the other is wireless. Download/upload speeds are over 900 Mbps on the Ethernet PC. I have not seen slow network indications on anything except this "YouTube TV" with Firefox mixture. Hardware does not seem to be the issue.

Apparently the problem is software. I also tried temporarily disabling my antivirus/firewall software. No change. I'm running Windows 10 version 21H1 and Firefox 88.0.1. I'm new to YouTube TV; although most of my viewing with it has been done on TVs, I don't recall seeing this problem in my PC tests a month or so ago.

The search engines I've added do not appear in the list after clicking the green + sign in the search box and they do not appear in the list in the options either. I used the "add more search engines" found in the bottom of the search engines list to find the missing engines and add them again, but when I find the engine I want to add there is only the "remove" button. So this tells me the missing engines in the list are still there but not accessible. I tried removing the added search engine and then adding it again but this did not make them appear in the search engine list. Everything was working fine until getting the last update before Firefox 89. Is there a way to fix this???

Hi,

I'd like to use keyboard media keys (play/pause, prev, next) to control Spotify web player and Youtube but they don't work. The option is enabled. I'm using Firefox 88.0 on Windows 8.1, so according to this article it should be supported. The keys work on other apps. I've tried in troubleshooting mode as well, no luck. Any ideas?

Fix it so the FireFox browser Version 88.0 for Ubuntu (Linux) works AGAIN at saving website Login data using a Primary password via your 'FireFox Sync' advertisement (documentation).

I downloaded the new version, 89.0.2, not realizing how really horrible it is. Since, trying to return to the old version (88.0.1), I've managed to delete my entire firefox directory, and have to reinstall FF from scratch. I've lost all history and bookmarks for the past 10 years. I can get by that. But, how do I set a photo from my pictures library to my FF homepage? Thanks for any relevant responses.

I used to run Firefox 88.0.1 (64 bit) on a Windows 7 PC. With lots of help from this forum I wrote a userchrome.css file to make several changes to the appearance.

On a new Windows 10 machine I installed the same version of Firefox (since I don't care for the latest one). I added my old profle to the new installation and selected it as the default.

Unfortunately, when I opened the program I was prompted to create a new profile; there didn't seem to be any way around this. So I let it happen and tried simply copying my old chrome folder into it - I thought at least I could make the visual changes even if I couldn't import my bookmarks and so on.

But this didn't work either: when I run the program, none of the expected changes are there.

Presumably I've done something wrong, but what, exactly? I'd be grateful for any thoughts. Ideally, I'd like to use the whole of the old Win7 profile but if that's not possible at least changing the appearance would be pleasant.

Many thanks.

i lost my previous tabs and i couldnt recover them. they were no were to be found in history. i need to restore tabs to a previous time or date to recover them and there is no such option, as i accidently closed the new tab and now its overwritten " previous" tabs.

Preview is opened as default when printing. I prefer to use the system printing. How can I discard Preview? The printing task now takes more than a minute to access the printer. It all started since Preview was introduced as default! Meanwhile Firefox i locked and I can't do anything in Firefox.
