Firefox Support Forum

Just refresh my computer, new install of Firefox, but all of my Bookmarks were missing, a collection of 25 years, all gone. Tried to sync with my XP computer, where the originals were, but it too was empty. Found JSONLZ4 files, two of them, one dated today and one dated yesterday. Both empty, is there any way to recover all those bookmarks?

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

(Firefox 94.0; Fedora 34; Gnome)

When I go to some video websites and click the play button, I see the little circular thing in the image are spinning, indicating that the video is loading. But it never stops and it never plays. Also, the pause button does not have any effect; the loading indicator keeps spinning. Example website: "https://proclassictv.com/" (both with "The Rifleman" and "My Favorite Martian" episodes. I've tried this on a few of the videos available there. Same result. I've tried this with add-ons enabled and with add-ons disabled (current session). I've seen this in a few other websites also. I don't know if the problem is my system, Firefox, or the host website.

I am able to view youtube videos with no problems.

How do I get the videos to play?

Thank-you.

Hello! Something in my Firefox installation seems to be making several Google network (google.com / forcesafesearch.google.com / www.youtube-nocookie.com / m.youtube.com, and a couple of others) calls shortly after launch. I have a DNS sinkhole, so that is how I can see.

I have a few reputable extensions (or should be, from EFF, Firefox itself, or Ublock Origin), but it also happens in safe mode. I went through a good chunk of this: https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections and still the calls occur

I am on Windows 10, with FF v93.

Thanks very much!

It took years to perfect my userchrome to make FF look exactly how I want. Once 91+ came out it wasn't even a question of fixing the floating tabs and condensing the height and menu spacing (though I tried all of it) but my own codes stopped working properly - I had code to set the background colour of menus/bookmark menus and when I upgrade they were the right colour but with thick white borders around them. This was more important to me than the floating tabs and I immediately downgraded to 90 where I've stayed. Can anyone help me figure out how to get MY codes to work with 91+ and/or to work together with the other fixes out there (tabs, condensed menus etc)??

Below is how my userchrome looks and attached is how my current set up looks. ANY advice is appreciated. THANK YOU.

This problem has been happening for a long time now. When I'm playing a playlist in YouTube, and YouTube automatically select the next song in the playlist, the song stops and I get the message "Playback Paused because your account is being used in another location". This problem ONLY happens in Firefox and with this playlist scenario. If I select the song manually in the playlist, the song will play just fine. I've used other browsers Chrome and Microsoft Edge and DO NOT have the problem in there so I know my account isn't being used in another location. I've tried using multiple PC's/Laptops and both Windows 7 and 10 and the problem always only happens when using Firefox. I checked the About section in Firefox and it's showing Firefox is Up To Date.

The List of Cookie exceptions under Security Setting, the ones I want to retain, keeps getting deleted. I select ALLOW for each one. What is causing the list to get deleted?

I didn't change any text settings of purpose, and I'm seeing this across a few different sites. What should I do?

Thank you!

I use the bookmark bar very heavily and my workflow was to just "drag" the tab with the mouse to folder in the bookmark bar, which would unfold and I drop the tab/bookmark in the desired sub-folder.

This worked really well for me, and was fast.

Recently, this stopped working. I can still drop a bookmark in one of the main folders in the bookmark bar. But not in any sub-folder, since the main folder closes as soon as I move the mouse inside it. It is also not possible anymore to move the already-saved bookmarks around via drag&drop.

System: Linux (Manjaro Gnome 41.1) Firefox for Arch Linux 94.0.2 (64bit)

I followed something in reddit. Now I have all my accounts signed out. This issue has been going because neither for my Temporary Add-on was working nor the buttons I tested. Is there anything to do to prevent this error in the future? I am starting to hate this browser as updates kept on-going and just slowly killing my browser ( especially losing pinned tabs for my important big projects in school )

Howdy, fellow Firefox aficionados.

I'm running FF on a Windows 10 Home 64-bit desktop. Some time ago, I suddenly could no longer open Firefox because it couldn't find my Profile. So, I attempted to create a new one, but it would not allow me to do so.

"Changes Not Saved"

   "An unexpected Error has prevented your changes from being saved."

[See uploaded Image]

More than likely, either I, or one of my system maintenance programs wiped some data or folder. I have deleted Firefox and reinstalled it with the latest version, but this dilemma persists.

Thanks for reading my post and if you reply, a big Thanks!

A very serious bug in all Firefox browsers (it's been around for several years!). If you open multiple tabs (many tabs) in your browser, virtually all settings will not work, e.g. you won't open Options, Menus, various tasks, extensions, won't save your bookmarks, and many other problems. Although the browser opens a page and the Tab works! But everything else is NOT WORKING, even in Safe Mode or Troubleshooting Mode! I've reported this many times: No developer help! Windows 7 x64 Firefof Latest x64 version 20 GB RAM 4xCore CPU

After creating a new Windows User account and switching back to original account, I lost ALL of my Quick Access Bookmarks! Then I did a Bookmark Restore using the most recent saved Bookmark file and I lost around 64,050 bookmarks!!! Now, the latest saved Bookmark file lists 5 items. This is a ridiculous and a very serious issue!!!

What is going on? I spend a lot of time getting important Bookmarks for research, and etc. How can I get all of my Bookmarks back? Apparently, I cannot get them all back. See attached file.

Hello together.

I'm experiencing the same problem as discussed in this cases that is not solved yet: https://support.mozilla.org/en-US/questions/1312836 https://support.mozilla.org/en-US/questions/1333547 https://support.mozilla.org/en-US/questions/1321038

Symptoms: After FF starting it loads pages fast enough. After several minutes of using pages start be loading very slow. Loading slowness increases until it becomes blocked continuously. Reload button has no effect. I tried everything from here: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - No effect.

Work around done: When windows is loading in Safe Mode the problem disappeared. If I disable Windows Defender Firewall the the problem disappear and appear after firewall enabling again in several minutes (same as after FF restarting) When I go to <current network settings> and switch Network Profile from Public to Private or from Private to Public the problem disappear but goes back just in several minutes (same as after FF restarting). Windows 10 Restorehealth has no effect, and reports that everything is OK with system files (DISM.exe /Online /Cleanup-image /Restorehealth ) The most strange thing Windows 10 In-place Upgrade has no effect.

I found out the core of problem is that Windows Firewall is blocking FF internal interprocess communication on local TCP ports. Yes, you would say it is not possible and firewall doesn't affect local port communication but in my case it is a fact. I used the ProcessMonitor from Windows Sysinternals, and Windows Defender Firewall with Advanced Security log. Screenshots shows this fact. On first two lines from Firewall log you see a Local Port Communication blocking, on ports 1401 and 1400. Next Screenshot from ProcessMonitor shows (see blue colored lines) that it was exactly FF communication, where I was trying to reload a page several times.

Any ideas what to do with it? It seems like Microsoft’s way fighting a concurrent web browsers, but I hope it isn’t.

Now I use FF version 94 but the problem starts from 88. I was trying FF downgrading to version 75 with no effect.

Hi all

I would like some help if possible please. When I start Windows 10 on my laptop and I open Firefox I open two separate windows (personal and professional) and then I open a pre detirmined set of tabs in each window to start my day.

Is there a way I can press open Firefox and I can have 2 windows open with all my pre set tabs?

Is this possible? If not, how close can I come to this?

Thanks,

I can no longer view Instagram in my browser. For a week or so I've had trouble with Instagram. I can log in but all I get is the grey Instagram camera logo in the middle of my browser window. The app on my phone works fine. If I continue to try logging in on my computer to see if it works yet Instagram locks my account until I enter a password they send my email. My eyes aren't great and I need to view Instagram on my computer monitor. Please help. How do I fix this?

I've been having an interesting problem with Firefox for the past couple of months regarding only Soundcloud, where after the first visit to the website it won't load, giving a generic "Sorry! Something went wrong" screen. Firefox will continue to not load the site correctly until I clear the cookies and the cache, which works but only for one visit, and as soon as I close the tab and open soundcloud again or refresh the tab the problem comes back. I have disabled all of my extensions as well as enhanced tracking protection when testing. A firefox refresh also did not solve the problem. The only way I can get the site to behave normally is when using private browsing.

The console is filled with errors regarding javascript files (source URI is not allowed in this document).

Thanks

Firefox 91

See screenshot.

I've been a Firefox user since the days of 2.0. I know what DuckDuckGo is, what search is, what it does and how to use it. I've set this search engine up myself! I don't need a tutorial.

How can I disable this misfeature?

Thanks, Alex

Hi!

When you open network tab on Firefox devtools there is request blocking option. The hint below text box says "Add URL patterns here to block matching requests" but there is no documentation how to write patterns. I tried to google it like 10 different ways and did not find any documentation.
