According to this support page (https://support.mozilla.org/en-US/kb/sync-custom-preferences#), setting ``services.sync.prefs.dangerously_allow_arbitrary`` to True will sync all my preferences.

I have set it to true on the two devices I want to sync (2 desktops, Windows and Ubuntu). However, the preferences are not synced. For example, ``browser.compactmode.show`` keeps its default value "False" on my Ubuntu installation, despite it having the modified value "True" on my Windows installation.

I have tried pressing "Sync now", and restarting the browsers - to no avail.

Could anyone tell me what am I doing wrong?

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

As of this morning, Sat 8-5-23, Outlook mail loads, I see a list of new mail in my inbox, but I'm unable to read any mail, or see any of my drafts. It loads, and works on Bing, and amazingly works ok in Firefox Private Browsing. Win 11 FF 116.0.1

On Firefox 116.0.1, I am unable to make a post on LinkedIn. I have cleared the cache and cookies. I tried a different browser and I can make a post! So I have concluded that it is a Firefox issue. Hope this is addressed soon.

I woke up this morning and realized my youtube wasn't working right. It was loading endlessly and wouldn't play right away when I clicked a video. I thought at first it was a computer issue so I restarted it; but that didn't change anything. Then I thought it was an internet thing, so I switched to my mobile hotspot; but still nothing changed.

I've restarted my computer 3 times, restarted firefox 9 times and done just about everything I could find online. I turned off the recommended hardware settings, went into troubleshoot mode (although I'm not tech savvy so I didn't really understand what to look for), made sure firefox was up to date, cleared my cache and cookies, made sure all my add-ons were up to date; and still nothing.

And it's the same for Twitch. It just loads endlessly and doesn't play anything. It doesn't give me an error or a bug notification; just shows the gracy spinning circle and nothing else.

The only way anything loads is if I turn the quality down to the lowest one possible and have it paused for a minute to let it load on its own.

It works fine in Microsoft Edge; but just not in firefox.

I was using my computer and Firefox all day to watch videos, browse twitter and Tumblr and whatnot until around 15:30 my time, when suddenly Twitter stopped loading my timeline. I thought it was an issue with Twitter or my computer. I restarted my PC twice so far and rebooted my modem (completely unplugged, left it alone for a min and plugged it in again).

I still cant load my twitter timeline, not even in private with all extensions turned off. It does load Tumblr, but like 80% of the pictures/gifs, even profile pictures do not load. When I search for something on Duck Duck Go it sometimes works but most times it just stays blank. Youtube videos either do not load at all, or stop loading/load endlessly at some point. I am still able to navigate the Youtube website tho.

I really do not want to use Chrome, but the latest update is just unusable. Am I the only one?

(I forgot the word for modem, dont judge me.)

Hello friends There is a serious problem syncing my Firefox data. After I uninstalled the old firefox and installed the new firefox on the new windows, I logged into my firefox account but none of my old data was transferred. Plugins, bookmarks, passwords, and other previous information usually need to be synced. Please help me to fix the problem and sync my account information in the new firefox.

Note: I have been using this account for several years.

I just upgraded my Ubuntu 18.04 to 20.04 and found that Firefox (which was working perfectly before), does not work properly. Graphics (eg. profile pics on various websites) are not displayed, buttons of websites are often missing, some websites are displayed in a weird "zoomed out" way.

With Google Chrome, I don't have these issues so it does not seem to be a Linux thing...

I already tried reinstalling Firefox, but to no avail...

Help is appreciated as I would not want to migrate away from Firefox which has worked well for me for years...

Regards!

Hi, with reference to the above subject, the Tumblr, outlook and other sites do not display photos/ text, operate properly etc. All these applications work fine on other devices, Apple ios. The firefox has been restarted several times and also pc as well. No new installation or any other major change has been done. Thanks

This is a many years old account/install with Netscape/Firefox, now 116.0.1, 64-bit Windows.

When offered a box for email step 1 login -- this site, for example -- FF auto fill offers my correct address first, but then there are two offered below that in the auto fill offers that are not mine.

How can I access where those are stored and remove those erroneous or mal email addresses?

Searching here infers the Profile; yes, my first guess, but my Profile is 725 MB ... so any hints available?

This last Firefox update had totally screwed up everyone's browser. Especially maps. Half of my maps, especially on Find A Grave no longer work. I dont know what you guys did, but you need to fix it fast!

Intermittently (maybe 1/20 times?), when I try to do a Google search from the URL bar I'll get a tab that doesn't load for about 30 seconds. If I search for the exact same thing in another tab it will load instantly, and if I select the url and press enter it will also load instantly. I am seeing this issue both when entering a search and when selecting text and clicking "Search Google for X".

I found a recommendation on a similar issue to set security.tls.enable_0rtt_data = false in about:config but I have seen no change with that setting.

media like .gif files and .mp4 files are used very frequently in the Discord servers I'm in and for some reason whenever those specific file types are used won't load/function. I noticed that while the DRM icon was present in the discord tab, that those two file types worked just fine; but I have no clue how to set it to always turn on for specific sites.

Having a problem with an mp3 content on all sites. In console I can see error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: Error no decoder found for audio/mpeg

The same error shows when starting firefox from terminal: [Child 1234, MediaDecoderStateMachine #1] WARNING: Decoder=11dddc400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error no decoder found for audio/mpeg: file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166

It seems like not a system problem, because I can open and listen an mp3 files in quicktime. And chrome browser also not having any problems playing an mp3 content.

Firefox installed with dmg downloaded from site, but also tried install with brew - same result. The problem occurs in incognito mode too.

I am frequently needing to clear the Cached web content, when doing development work on a website. I always need to remember to remove the check mark from the Cookies box. However, I sometimes forget and loose dozens of log-in cookies and need to reset them, which is a big pain.

I was unable to find anything in the Firefox Advance Configuration settings. In Chromium and Chrome browsers, only the Cached images and files box is set with a check mark. If I cannot change the default for Cookies, this is reason enough for me to switch browsers, despite using Firefox for many years.

Hi, I found this post https://support.mozilla.org/en-US/questions/1270782 and I tried but there is no option privacy.file_unique_origin

and it still doesn't work (screenshot)

Hi Firefox...I am unable to sign in to this website in the traditional way. When I attempt entry I get the following message. "Hmm. We’re having trouble finding that site.

We can’t connect to the server at secure.adultfriendfinder.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)".

This is the ONLY site, that I have where I encounter this issue. Technical people say that it is not on their end.

I can go to my neighbors computer and immediately gain access.

I have turned off NORD VPN...no success I have turned off Pi Hole...no success I have change search engines...no success...I use DDG on all sites...using Google or Yahoo search engines did not effect the outcome. I have refreshed FF...no success I have deleted and re-installed DDG ad on...no success I have included a screen shot of what I get when denied access.

The only way to gain entrance is to go to the "FORGOT PASSWORD" tab and put in a new password.

The irony of that is, even if I change the PW, and allowed entrance when I log out and want to re-enter I have to change the PW again

Please help me some resolve to this issue...thanks doug

I went to about:config and set my privacy.globalprivacycontrol values to all True. Yet, when I go https://globalprivacycontrol.org/, the website states that the GPC signal is not detected. Is any other action required? I am using Firefox v16.0.2 on a Mac computer running Ventura 13.5.

Running Windows 11 on a Dell XPS 8930. Internet download speed is 100Mb/sec. With every update of Firefox it seems to take longer and longer to launch Firefox and load open windows and tabs. Several minutes of the back and forth ball on each tab. I can launch Chrome and its windows and tabs load almost immediately. What can I do to improve Firefox performance, short of abandoning it?
