Firefox 技術支援討論區

I'm using 121.0 for Manjaro

Today, I had a problem trying to re-load a website I had saved just the other day. I have a bunch of such websites for a technical project I am working on.

I tried loading the other saved web-sites. All had been saved as a complete file and by this browser. I have no other browser installed.

The problem was that the saved web-page kept re-loading. No forum-discussion could be found so the trouble-shooting option was entered into.

I opened Firefox in safe-mode (via the command-line call). Running a suggestion; clearing cache didn't resolve the problem (in safe-mode the saved web-page still kept re-loading with a rapid cycle)

The next "suggestion" I tried was refresh Firefox. Firefox advised that none of my saved data and settings would be lost. Well, my entire profile is gone!!! Thankfully synchronizing worked such that I could recover passwords, history etc. What are NOT recovered are the settings for websites, probably other infos too.

I have two login-accounts on my system and I have a shared, common profile for both. This was using a public folder with access rights only for those two users.

I have been using that profile architecture for months. This is now gone!! Those folders do not exist anymore. In its place are entirely new folders, their formats completely unfamiliar to me. I am recalling my latest backup but will it be of any use???

Many thanks, indeed.

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

Over the past few weeks I've been unable to watch live videos on Firefox on Ubuntu 22.04. I thought it was just an issue with Twitch but I realized the problem also persists on live videos on Youtube and did some troubleshooting which didn't solve the issue. The only solution I was able to find for Ubuntu said to install ffmpeg, which I already had, but I made sure it was upgraded, refreshed Firefox, and still have the issue. Currently I'm on Firefox 121.0 but I've had this issue since before I updated it. I dual boot Ubuntu and Windows and am not having this issue when I boot Windows on the same computer and Firefox profile.

Since about one year I am unable to use Japanese input only in Firefox. When I try to switch with fcitx and control+space, nothing happens. However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.). Furthermore, I uninstalled fcitx and everything associated with it and reinstalled it according to this thread: https://support.mozilla.org/en-US/questions/1367181 (just with mocz for Japanese). This also didn't change anything. Any help is appreciated! My system: Operating System: Linux Mint 20.3 Kernel: Linux 5.15.0-91-generic Architecture: x86-64 fcitx version: 4.2.9.7 Mozilla Firefox 121.0

Dear friends at mozilla.org,

Thank you for your excellent browser, which I've used almost from its first versions.

I'd like to compile its source code, which I've downloaded from your website, into a working browser. I've spent several days, and get only as far as not-terribly-helpful error messages, that indicate strongly that I'm using versions of tools and libraries that the source code doesn't like.

I'm using

 linux kernel 6.1.0-13-686-pae (from Debian)
 gcc 13.2.0-9
 perl 5.36.0
 python 3.11.7

It's sufficiently important for me to compile firefox that I'd install a fresh linux system for this purpose. Could you possibly recommend to me what linux distribution I could install, and versions of compilation tools, header files, libraries, etc. that are known to work for compiling firefox? I'd be glad to report back to you my results, to help others who'd like to compile firefox.

In case you're wondering, I'm perfectly competent in installing software, including compiling anything. I'm an M.I.T. graduate, and have been a professional computer programmer for most of the half-century of my working life.

Thank you kindly for any response that you have time to send to me.

Very truly yours,

Lyman Opie [email address]

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

When I click the address bar, Firefox lists favorite sites. How do I disable this list until after I've typed?

I don't want the list because I don't want to be distracted by these sites.

While they are safe-for-work, I'd rather "fun" sites didn't come up when I'm working with other people.

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

When I open a new tab in FF, a row of 8 boxes appears below the search bar where I can add shortcuts. I currently only use 5 of them, meaning there are 3 empty boxes left over. I don't want to have them show history, or recommended websites, or anything of the sort that might distract me; the shortcuts should only be those I actually intend to use, of which there are only 5. To my knowledge, the only easy way to add/remove shortcuts is to adjust the number of visible rows, but this only allows modifications based on multiples of the original 8. Like in Chrome, can I actually remove any excess shortcut boxes I don't want to use? I feel this is a very basic customization I'm sure Firefox should be able to accommodate.

I've included a screenshot of my FF new tab, where the three empty shortcut boxes I'm referring to can be seen. Thank you in advance for any assistance!

I fill out a specific online form on a regular basis. When I used Chrome several months ago it always remembered my form data. But no matter what setting I set I cannot get this to work on Firefox.

Under Privacy & Security I've set History to Use custom settings for history: Remember browsing and download history enabled Remember search and form history enabled Clear history when Firefox closes disabled

I have also checked antivirus, antispyware, firewall, and privacy programs are not interfering. I do have a VPN but only use this when using online banking.

Hi, it has occurred to me that I lose the browsing history of tabs that were open for a long time. By browsing history i mean the sites that show up in "Go back one page" arrow. The issue is that after a website has been open for some time (this seems to be in range of days, perhaps weeks) the browsing history of that tab is forgotten and the Go back one page arrow goes blank. I would like to be able to keep this history for eternity, is there any way to enable that?

To be clear, I use the feature to save tabs of my previous sessions and also the Simple Tab Groups extension.

Thanks in advance, Alex

After using gnome-tweaks to change my system fonts, Firefox has unexpectedly gone silent and no longer shows text in areas like the search bar, tabs, settings, bookmarks, and menus. Rendering websites works just fine, but Firefox itself won't show any text.

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Is there a way to use the default xfce windows instead of firefox`s own? I mean I have my own setting in the xfce window manager that are not applyed to firefox. fo example: I unchecked Raise windows when clicking inside application window, that is not applyed to firefox, I also have a context menu when right clicking on other windows title bars that I can customize, In firefox I have something total else.

I have constantly crashing tabs with FF 121.0.1 32-bit on Debian (happening since at least 120, and probably 114 or perhaps 115 ESR), and about:crashes has no listing of any tab crash reports; this hasn't been an issue until the most recent version. I'd like to report them so that they could hopefully be fixed, but reporting doesn't seem to be happening? Thanks.

cannot download firefox browser because I have an expired chrome browser that I'm supposed to delete first -

However - have tried a dozen or so ways to do just that - or so it appears and still cannot download the

firefox browser and after much frustrated key pounding find evidence chrome is not really deleted - help losing

my mind - I'm 77 years old and not computer literate but not senile either - i hope

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

The Debian Firefox packages available are only 115.6. Thought it would be nice to have the latest. Grabbed all the dependencies according to the Mozilla web site.

Installed Firefox 121.0 as root and placed folder into /opt, as instructed. Went through all the settings and imported my bookmarks.

Now there is a 121.0.1 upgrade available but my browser won't automagically install the upgrade. Says click here to download. So I do. I get the entire tar.bz2 bundle, which creates a full directory structure, as if I was starting over.

Can I just move a few files from that into the existing /opt/firefox directory to get the upgrade? If so, which ones?

Or, can I move few files from the existing directory into the new version, and replace the whole lot? If so, which ones?

Thanks in advance.
