Firefox 技術支援討論區

I've some search engines which was configured a lot of years ago (or maybe was imported from another browser many years ago). They are working in address bar (e.g. I can enter there "cve something", press Enter and get redirected to https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=something), but not listed neither in about:preferences#search nor in my profile's search.json.mozlz4 (I've unpacked and checked it - it contents does match about:preferences#search). I've tried to grep for "cvekey.cgi" in my profile folder but get no results (I suppose these "hidden" search engines are stored in some sqlite file).

I'd like to have these hidden search engines listed in about:preferences#search. I can even manually re-add them, but how can I find complete list of all configured search engines?

I know i can slow click on the icon to get to a second window, but there must be a kb for that. the help muddles the meaning of tabs and windows. I want to switch to the next window with a different tab bar where i put pocket so i can save to it

Okay, PopOS 21.04, Firefox 92.0 x64, my packages are up to date, my graphics card (Nvidia 1080) drivers are up to date (nvidia-driver-470 (proprietary)), kernal 5.13.0-7614-generic.

I run a variety of addons, but the only ones that should even be touching YouTube in any way would be Noscript, Ublock Origin, YouTube HD, HTTPS Everywhere. In the past with my current configuration none of these have given me any issues with playback.

I don't have any idea why, this is a problem I experienced a long time ago and now newly the other day for seemingly no good reason, videos on YouTube but also the web in general will not play until I open Firefox, close the browser, open it again, and then try and do whatever it was I'm trying to do. While not a fatal issue, this is one that is extremely annoying and I really don't feel like putting up with it.

Anyone have any advice or information?

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

Hello. For the past few days, I am unable to access the content of some websites. For example, Reddit seem to load but the page remains blank. This happens on other websites, where I am unable to login although the page displays correctly (an error message appears on one of them: "Please check the consistency of your URL").

This is quite annoying, especially because I cannot find anything related on the web. I use Firefox on POP OS 22.04.

Thanks. Cheers.

Zorin16-Linux version 99.0 Ubuntu Canonical 1.0, -found in Help/About. Firefox recognition of version below says 91.0. Also have Linux Mint 19.3 (Tricia). Computer 15YO Dell Dimension 900.

I've had no problems with Linux Firefox for many years. I do not use any other Non-Linux OSes. Linux Mint updates Firefox regularly and so do I in that OS. I'm currently in a free version of Zorin which doesn't seem to push out updates, so my Zorin Firefox may be sadly out of date.

At any rate, today in Zorin, when I went to several of the bigger online sales platforms, they refused to accept my Firefox and suggested Chrome, Opera, and Safari; Target suggested Firefox.

Went to Mozilla to try and upgrade, but it didn't offer the Linux browser automatically when it read my computer. I was only offered the Windows browser. This may be because the computer is an old Dell Windows machine that I converted to Linux or it may not. I've never had this happen before.

Yesterday in Linux Mint, in which Firefox is upgraded at least weekly, the same thing happened once with a big online retailer. They said my browser was outdated and unsafe.

What's going on? I'm wondering if Linux OSes are simply not being accepted when the big retailers are doing software upgrades, or is something going on with Firefox?

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

When I click the three dots in the address bar to open the page actions, I am not able to see any options it shows an empty box. It started happening recently. My version is 84.0.

Thanks in advance for helping out.

Ps. I have attached the screenshot of what exactly is happening.

Hi,

Am I the only one plagued with an issue about the option "View" > "Toolbars" > "Bookmarks Toolbar" > "Only Show on new Tab" ?

It finally used to work until version 88

(prior to that I had to use custom css tricks)

With 89, it does not work anymore

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

An automatic update of Firefox which resulted in a "quit/create new profile" choice has removed all my bookmarks

Of the four profiles stored in "about:profile" three are identical (ie. have only the default bookmarks stored) and one, generates a "quit/create new profile" message.

The "bookmarksbackup" folder (in /home/user/.Mozilla/Firefox/zs1jki8t.default) is empty.

The "import/backup" option (in Manage Bookmarks) offers nothing to choose. There is no 'list of dated automatic backups.'

Firefox did not create an "Old Firefox Data" folder on the desktop.

Browser privacy "strict". "Never remember history" was selected.

Running Firefox in Manjaro (Linux)

Help.

Hello,

Since recently the bookmark dialog has changed its behaviour, and to worse from my perspective. If I don't do anything for about three seconds, the dialog closes and the bookmark is saved to a place where I most likely don't want it to be saved. Is there a way to get rid of the three second time limit? Thanks!

It's not necessary to read further to answer my question. Bellow I'm going to give some criticism and express frustration about this new feature (or is it a bug?). The criticism is not directed towards the nice people here who give support to users who have problems.

I understand that developers get new ideas and want to put them into practice, but if you change an often used behaviour like this, I don't think it's user friendly to just change the behaviour without asking the user if he want's that behaviour. Personally I don't see how the automatically disappearing dialog helps me (it's very easy to click Esc if I change my mind about bookmarking a page), but I keep experiencing how it makes my browsing experience worse, as I often pause for a moment for example to think what name I'm going to give for the bookmark, or where am I going to place it.

In practice this change has wasted at least an hour of my time (to find an explanation and (in vain) a solution to fix the behaviour), made me annoyed, and based on the comments here and other places, made quite a few other people annoyed too.

Please, when you change the behaviour of Firefox in the future, before changing the behaviour for an individual user, ask him first if he even wants the change. For example show him a dialog where he is told that "we have this new feature where your familiar dialog keeps disappearing every three seconds for no reason so that you get the pleasure of invoking it again...and again...and again. If you want to have that feature, check the box on the left".

This problem occurred Oct 24, 2020 Australian Eastern Daylight Savings Time (3 weeks after daylight savings time came into effect here). The operating system time is correct. I have cleared the cache several times, rebooted and shut down overnight.

A forum site is displaying the correct times. A site displaying weather information uses the correct time; I loaded it just after 3am and the first time it displayed was 6am as expected.

1. A TV guide normally highlights in red programs currently showing; at present it shows programs showing one hour previously. In Google-Chrome no programs are highlighted. I have removed the cookies and that has made no difference. 2. Facebook.com times are one hour late, both the time of posts in the newsfeed and times of notifications.

Hi,

searching for bookmarks (with sidebar) is no problem. There are several cases where I look, if something or similar had been bookmarked already. With this I want to avoid doubling/tripling/'moreling' bookmarks. But if I find something already bookmarked, I do not know in my about 1000 bookmarks where the bookmark is located. I tried to show properties of the found bookmark but it does not tell where it is placed. So I would have to look manually about 100 folders to find where the bookmark is located.

The most easy solution I think, would be indicating the place of the bookmark when showing settings of bookmark. On hovering over the found bookmark in a third line of popup could be told the location of this bookmark and would be visually more pleasant I think.

Else I have to put the bookmark doubled in a more visible location and delete the bookmark found by search. This workaround works but is not intuitive and bothersome (and costs much more time).

As this solution would be easy to implement, I hope, this can be implemented 'soon'. I think, this would help many others, too. (At least I heard from several others in my environment, that they miss such a thing.)

Not forgetting, thanks for the great browser, Niels

When you click on the address bar a drop down menu appears which allows you to immediately select a site that you visit frequently. How do I remove an item from this menu?

I know that a extension, ones that add functionality can be installed from a local file on my PC but i need to know how to extract the extension and store it on my home PC ? I know there are scripts available but i don`t remember where.

Cannot get rented/paid Youtube or Netflix video to run. Message "! Sorry, there was an error licensing this video" pops up onYoutube screen every time when hitting play button. "Free" Youtube videos work just fine, paid content gets this message. Have firefox-9.5.0.2.ta.bz2, use Linux updated software. Followed all previous suggested Support, cannot seem to find fixes that included DRM, Safemode switch, etc. Thanks for previous help, still stuck... anymore ideas appreciated. Also, difference between running "normal and beta", please explain, and how to know "differences?"

I have deleted my bookmarks with the Bookmark manager, but where are they now? I cannot find them in /trash and all of the *bookmark* files on my laptop are miniscule (like 127 bytes.) The json files are no better, when I imported previous bookmark files they were empty.
