Firefox 技術支援討論區

I am running WikiSpecies on Ubuntu Firefox 64-bit v. 98.0.2.

I used to be able to display a collection of unused files with the used ones but showing a red color indicating that the file was unused (because noone had entered anything other than the file name).

Now, however, ALL files in a directory (e. g., see https://species.wikimedia.org/wiki/Craspedophorus) are shown with the same color, whether they include additional implementation details or not.

Would it be possible for you to restore the "unused" color of empty files? It is bothersome for me to open EVERY file, empty or not, in a directory just to find that most or all of them never have been implemented. Adding a special color -- or other distinctive display -- to unimplemented files would save me a great deal of time.

I am attaching a picture of a typical unimplemented file.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

When downloading files, FF opens a window to file manager. The window enables user to choose the download directory. But the window extends past the right side of the monitor, thus the "save" button is not displayed. Thus, files cannot be saved.

Hi,

I have a problem, which only seems to apply to Firefox. I am a developer for a site which uses LetsEncrypt certificate. When I access it via Firefox (and only Firefox), I get the error message as mentioned in the subject.

I tried to understand why this occurs. A quick Google just leads me to an issue with the Microsoft domain, and what I can understand was a Firefox bug.

Trying to figure out if it is a problem with Firefox, or a problem with the certificate. Any thoughts?

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

I just discovered this PPA thanks to OMG Ubuntu. But is this PPA official?

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hello

I do not understand how firefox sync is supposed to work. I have a desktop and a laptop. The desktop is FF 85 on Linux Mint (I cannot get a later version due to some querk) The laptop is 99 on Windows 10 Both are signed in to sync but my bookmarks were scrambled so I signed out the laptop and cleared the profile, cleaned up the bookmarks in the desktop and to be safe I tried just syncing the tabs, not the bookmarks, by opening the fresh firefox on the laptop and signing in again. In the sidebar under my account icon I clicked "Synchronise now" and the open tabs from my desktop appeared in a list underneath, jumbled up. (I have 2 separate windows open on the desktop with different tabs in each, but this separation was not followed either, there didn’t seem to be any provision for syncing tabs in two separate windows)

But the row of tabs didn’t open, all I can do is open them one by one from the list on the right, this is a slow process as every time I click on a tab in the list the new page opens in the same single tab, not a new one, but the sidebar closes again.

Is this what’s supposed to happen? I was expecting the synced row of tabs to open automatically.

This feature would have been useful as my OS on the desktop, (Linux Mint) tends to crash and to have the on the laptop would be a good backup.

Incidentally the other way I try to back up the lost tabs is to select them all and bookmark them to a new folder which I call “backup” but it seems this doesn’t necessarily duplicate them, which I would prefer, so any of the open tabs that were previously bookmarked risk being removed from the original bookmarked folder, without my noticing, and I am therefore reluctant to delete the backup folder without checking that it doesn’t contain the only bookmark of a page.

When I came back to syncing the bookmarks, how do I avoid them getting scrambled again?

I started using Linux Mint a few months ago, and since then have had issues with opening Firefox on startup. The attached image shows roughly what Firefox does the first time I try to open it after starting my computer. I usually have to close and re-open it 5-10 times before it will launch properly. At this point, I usually manually recover my previous session. Does anybody know of a potential fix to this problem? I have tried updating Firefox and have also tried uninstalling and reinstalling.

I am developing an extension. I am running the extension locally and I have noticed that it doesn't load on this page (https://support.mozilla.org). Is there some limitation to running extensions here? The same extension works fine in google chrome for this page. It is very important for me that the extension runs everywhere since it's an accessibility extension.

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

Firefox cannot access my local filesystem. When I open a PDF in the browser and click the Save button, nothing happens. When I click a "Browse..." button to browse the filesystem and upload a file to a website, nothing happens.

This issue does not happen in Google Chrome. This issue persists in Troubleshooting Mode.

Please help! I'd be glad to provide more details as requested.

Hi,

I've upgraded to Firefox 99 (on Linux) and a website that works fine in Firefox 88 and Chromium 101 has stopped working for me - I can't get the log in form to show up.

This is in a standard window (as opposed to private) with all add ons disabled, Enhanced Tracking Protection switched off for the site and protection settings set to 'Custom' with everything switched off (and same with protection settings set to 'Standard').

The website is:

https://www.riverford.co.uk/

and then click on person icon in the top right corner.

I'm having similar problems with other websites, eg

https://www.ebi.ac.uk/interpro/

in a private window (but weirdly works fine in a standard window) - click on 'Example protein sequence' to fill in a sample sequence and then press 'Search'. In a standard window this works but in a private window the 'Search' button doesn't work. (If the search button does work for you, please delete the job afterwards by clicking on the rubbish bin/trashcan icon so as not waste their resources.)

I lost my arrows on my scrollbar again after an update early last month. I tried adding lines to the gtk.css config files with no success unlike I've been successful doing in the past. It appears they are gone forever unless I can find another way to get them back. I noticed that the scrollbar arrows are gone on only Firefox and Thunderbird. As mentioned, this has happened in the past after some updates but in the past I was able to edit the gtk.css files in both gtk-2.0 and gtk-3.0 to get them back. Is there anything else I can try. I'm using the latest version of Ubuntu (Pop OS to be specific) and the arrows to the scrollbars disappeared around April 2nd for both Firefox and Thunderbird. I didn't notice any other applications where the arrows to the scrollbars disappeared. Is there something else I can try and a way to prevent this from happening in the future. This seems to be a common problem that happens every time there is an update.

Hi team, Can you explain me how exactly firefox sync works? asking because I thought by syncing it will save all the bookmarks with my account and I can use the same account to bring back all the bookmarks on another device.

I created an account on linux dual booted with windows and synced all the things I saved on firefox. Recently I switched to pop os and logged in using the same account. Expecting to see all the bookmarks on here too. But unfortunately it didn't worked. And all my bookmarks are gone. Is there any way I can recover those data?

Kind regards

Hello I have problem on my fedora workstation. When i click right button on the lowest bookmark on my list, the menu is hiding outside the screen and i can't see options.

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.

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.
