Firefox 技術支援討論區

I run a local web server from my desktop PC. As the person running it, I access it only from my desktop PC, and only my account has a password. (All other accounts must be created by me, and have very limited access.) When I log in, Firefox whinges that it's not running on https, which is not my fault, as I didn't write this server. I cannot change servers. How can I prevent Firefox whinging about my lack of a secure (despite being local only) connection?

I am desperatly trying to play a youtube video, the on hover preview plays, but the video wont. I turned hardware acceleration of and tested in safe mode. I am using Firefox version 115.0.3 from the AUR. pls help

The settings page just shows a number, but no units as on my laptop's default font settings page. I think that they are pixels, but I'm not sure. I want to set my font sizes in points, so that the text will appear the same size on my laptop's screen as on my much larger external monitor.

Earlier today (well, it's yesterday now) Firefox was updated to 116 and since then it won't download any images or other files from anywhere. I've set a default download directory and when I click "Save image as...", that image should appear in the preset directory but it doesn't. I have two extensions for downloading images and they work just fine, only the default function of firefox doesn't work. Here's a short video showing the problem:

I tried downgrading Firefox to 115.0.3 but that didn't fix the problem and I'm out of ideas how to fix it. I'm 100% sure it's a firefox problem bc I tried saving images with Opera and Chromium and there was not a single problem with that task in either of these browsers.

I use userChrome.css and userContent.css to (1) turn unvisited links bright red, and (2) turn visited links bright purple, and (3) add underlines to all links.

This works well on light backgrounds, makes links easy to see and easy to distinguish from other text, but makes them harder to see on pages with dark backgrounds.

Is there a way to vary the link color to improve contrast? I can't use the default colors because most sites use blue links which are hard to distinguish from black text.

My Wife and I are both 75 years old and have huge problems coping with modern computer technology. We have 3 computers with Ubuntu and Firefox. We find that we are able to successfully connect with most of our accounts. With some accounts like Royal Bank, Nextdoor, Koodo, TD Bank, Canadian Government we get in but only get a blank page and cannot go further. Accounts have told us the problem is Firefox and that we need to change to either Chrome or Edge. We have been with Ubuntu and Firefox since 2006, love both and do not want to change.

Hi, I've been struggling with this for months and can't find an easy solution or a good explanation. I'm running Ubuntu 22.04 pretty basic, I don't have many custom repositories enabled or anything, just a few additional packages like slack, Teams or Chrome. Ubuntu switched Firefox to snaps as well, and I can't get internet access with it. The error message is:

--- May 12 12:16:20 nuc kernel: [12948.381392] audit: type=1400 audit(1683886580.562:131): apparmor="DENIED" operation="open" profile="snap.firefox.firefox" name="/etc/fstab" pid=7731 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 May 12 12:15:43 nuc rtkit-daemon[1030]: message repeated 3 times: [ Supervising 10 threads of 4 processes of 1 users.] May 12 12:16:20 nuc dbus-daemon[790]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.175' (uid=1000 pid=7731 comm="/snap/firefox/2645/usr/lib/firefox/firefox " label="snap.firefox.firefox (enforce)") ---

Simply stopping (and aa-teardown) doesn't work at all, Firefox doesn't even start without apparmor running. I'm not an expert with apparmor, but I wanted to set in complain mode instead enforce, but I'm struggling with that, too. I didn't touch the /etc/hosts file, the error message is a little different on another Ubuntu 22.04 computer I use, there it complains about permission denied for the resolve.conf. So I'm asking the community, how do you deal with this? Searching the web gives me all kinds of ideas, but none of them work. Could anyone help me out here?

Thanks!

Hello,

Am using Mozilla Firefox installed via flatpak on openSUSE. Certain pdfs display correctly but other pdfs displayed with Firefox (either locally or online) are displayed badly: spaces are replaced with a lower half block character, fonts not sharp. I installed Firefox from the openSUSE repos (not from flathub) and opened the same pdf and it displayed correctly. I downloaded the pdf and opened it using Okular and no problems. I also opened the “troublesome” pdfs on Firefox in Windows and it displays correctly. I conclude that the flatpak version of Firefox is causing some pdfs to display incorrectly but I don’t know why.

I installed flatseal to tweak the flatpak Firefox’s settings but nothing seemed to fix the pdf display issue. Please see screenshot below of how Firefox (from openSUSE repos, on the left hand side) and Firefox (from flathub, on the right hand side) display the same pdf from the internet. The online pdf in the screenshot and used as an example of the issue can be found at:

https://www.jrf.org.uk/sites/default/files/jrf/files-research/international_cities_rotterdam.pdf

Not sure why some pdfs display correctly in Firefox from flathub and others display incorrectly. I’d prefer to use flatpak’s sandboxed Firefox if possible. Is there anyone else with the same problem or someone who who found a solution to this issue?

Thanks

I just spent 15 minutes browsing and downloading a lot of images. When I was done I looked at my downloads folder and saw only half of them there. I checked the download history in firefox, and couldn't see some files. They were not queued or in progress. They weren't in the download list at all.

I reproduced this. I downloaded an image again. Right click, save as, click save. Then that image doesn't appear in the download history.

I tried some variations. Hitting enter instead of clicking save. Opening the image in a new tab and using ctrl-s.

Still, no image in the download history or on disk.

I quit firefox and re-openned. Still the file didn't appear on disk or in the download history.

Then I kept trying, and I got a second issue, which I think is related.

Often when I save an image, instead of one window popping up asking me where to save it, I get a second window popping up ontop of that, then a third, then a fourth. All ontop of each other. All asking the same thing. They take the focus, so it's not possible to interact with the main firefox window to continue browsing.

Sometimes if I hit enter literally 50 times then it will save the same image repeatedly, and eventually I can go back to browsing.

Sometimes there's more than 50 popup windows (my hunch is more than 100). My only solution then is to quit firefox forcefully. Which is annoying if I have state in other tabs that I don't want to lose.

This has happened many times over many weeks. It only happens on some file saves. I can't figure out why it happens on some, not others. (Right click > save, and also ctrl-s, they both do the same thing.)

This form won't let me attach a screen recording. Only screenshots. That's annoying because you can't really see the behavior from the screenshot. But I'll try. See the dark black border outside the download dialogue? That's normally a very faint transparent shadow. But because there's so many duplicate windows all exactly ontop of each other, those multiple transparent shadows have become opaque.

What you can't see from a static screenshot is that I could see each window appear ontop of the other. If I try to select the filename text and edit it, very quickly another window appears ontop with the default filename again. I can see the Firefox icon in the Gnome bar on the left shaking every time a new window pops up.

(Hmm, it looks like I can't *upload* screenshots either. I click browse, select a file, and then it doesn't get uploaded.)

I'm on Ubuntu 22.10 with Wayland.

I don't know if this issue is a bug in Firefox, or in Gnome. I've only seen this behavior with Firefox in Gnome. Not Firefox on another DE/OS. And not any other application in Gnome. This behavior has been intermittent since I bought this laptop and installed Ubuntu about a month ago.

Computer: Linux Opensuse Firefox up to date

Hello,

after porting my SSD Arch installation from my old Laptop to a desktop PC, i have a really long startup time (about 30s-45s) for the first time after booting my PC. This problem doesn't occur with any other programs. The subsequent openings of firefox happen instant.

Have tried using "refresh" functionality to clean up firefox so my about:config is as clean as it gets, didn't help. Have tried starting it with "firefox --no-remote", didn't help. Have tried starting it with "firefox --safe-mode", didn't help. Have tried starting it with a completely fresh profile, didn't help. Tried purging it from the system and reinstalling it, didn't help. Same problem when I start it normally via dmenu/rofi.

I don't get any stdout log on any of these methods of starting.

I also don't know where to look for helpful log files.

Any help or hints on where to trace this fault are much appreciated.

Have a nice day :)

When browning some site will cause a Firefox to freeze, all UI stops working, if I try and reload the page nothing will load and if I try and close and reopen Firefox I get a zombie process that last for about a minute. Obviously this is with no ad dons or hardware acceleration and nothing is listed at about:crashes. The only useful tip I have comes from the command prompt. First when the freeze is first triggered I get the errors ``` MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen ``` and when I try and open it after a freeze and there is still a zombie Processes ``` [Parent 111218, IPC I/O Parent] WARNING: process 111455 exited on signal 15: file /build/firefox-RH6krf/firefox-115.0+build2/ipc/chromium/src/base/process_util_posix.cc:264

``` and finally when it kills the zombie processes ``` RunWatchdog: Mainthread nested event loops during hang:

--- CanvasManagerParent::Shutdown

ExceptionHandler::GenerateDump cloned child 111871 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... ``` the included images are what pops up when trying to open Firefox when it still has a zombie processes and when it kills the process

Firefox on my Alcatel phone misses chunks of text out from every webpage, Google search etc.

I tried opera mini, that works fine.

Anybody else had this?

I'm developing a PWA website that relies heavily on the sqlite.org wasm libraries and origin private file system (OPFS). On firefox-dev 116.0b8 my website at app.kumaflash.com stopped being able to read the database it had been successfully using for months prior to that. I've also asked on the sqlite.org forum here: https://sqlite.org/forum/forumpost/3bb8b83c45 but haven't found any solutions yet.

You can see a thrown together video of the app working normally here: youtube.com/@kumaflash

and the error I receive is: OPFS syncer: xRead() async error: GetSyncHandleError: Error getting sync handle for xRead(). 6 attempts failed. kumaflash.db : NotFoundError: Entry not found

If I manually open the OPFS in the console I can see that the file is there with this helper function in my app: var p = await _app.xdcards._lsOriginPrivateFSDir("/"); //that's an L for list ListOriginPri...

Additionally I can't debug because the firefox debugger crashes whenever I try to inspect my app. The debugger crashes on firefox-dev and release versions on every computer I've tried (with this app only). The chromium debugger works but the error doesn't happen there.

Any ideas on what I should try?

I want the version (which i assume is the ESR one) OFF my computer. I have downloaded a "regular version" (116.0.3) and have followed all instructions I have found on this site. It gets to a point and says it can't find the file. There is no README or Install file in the download so I am stuck. Please help me because I want the ESR version GONE!!! Thanks for any help! R

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

i tried changing any and all settings, clearing cache, using troubleshooting mode etc to no avail.

i use fedora 38 beta (it was also a problem on 37 stable) with ffmpeg installed.

i use biwarden, sponsorblock, ublock origin, stylus, google container, youtube shorts block and some custom css.

i am running a system with an i3 10105f, an rx 6600 and 16gb of ram.

firefox is installed with the version off of the firefox website.

reinstalling it worked briefly, but it broke again after a little bit of time.

i am sorry if i did not provide adequate information.
