Firefox Support Forum

Hello, as of this morning, none of the bookmarks I save on my android phone are syncing across to my PC. When I open my PC, I can see that sync is still working (as all open tabs on my phone are showing as open on the Tabs Pickup screen). I can see that several pages I bookmarked yesterday have saved without issue, so this is something that's happened today. I have my PC set to clear history whenever I close the browser, but I've manually cleared all history and cache. I've also manually synced. I've gone into settings and checked that Bookmarks are still selected as one of the things to Sync.

I have gone to about: sync-log and this is what I see:

Can anyone help? I've been using Firefox for years on my PC, but have only recently started using the Firefox app on my phone and I love the sync feature. Many thanks.

公司電腦被重新安裝 所以必須重新登入 firefox 但之前當作 帳號 的MAIL 已經停用被移除了 所以 收不到 確認信 接下來 我將如何處理呢? cclsfh@wym.com.tw 已經停用了 現使用的MAIL 是 : cclsfh@f-mi.com.tw (因公司名稱變更)

I have a feeling I know the answer, but wanted to confirm. Due to unforeseen circumstances, I had to reset my PC. Upon doing that and downloading Firefox all of my data is gone. Bookmarks, saved logins, etc. all gone. I thought once I logged into my Firefox account everything would be there. I've logged into my account on other computers in the past and all my stuff was there but not this time. Now it's saying all of my stuff (profiles, etc) was created today. Is my stuff really gone forever? I thought the whole point of the Firefox account was so I could just login and have everything sync.

Firefox won't reload tab when NoScripts running. This didn't happen until I went to version 11.4.18 of NoScripts and Version 111.0 of Firefox (both at same time). All 8 tabs load when I initially start FF 111.0. All tabs reload with no problems when I initially start or restart FF with Noscripts active. It is only after FF been running for an hour or so that tabs stop reloading. I do have another addon running called tab reloader. Addon tab reloader and the FF reload icon both stop working after FF runs for awhile. You will see the web page name in bottom left corner of screen and an hour class on tab. Stop NoScripts, the hour class goes away and all tabs reload, both with the FF tab reload icon and the tab reloader addon.

I thought it might be the tab reloader addon, so I set 8 tabs to reload every 10 seconds for awhile, just a couple minutes. NoScripts was running. This didn't cause a problem, everything was reloading. So I set tab reloader back to reload 8 tabs every hour, No scripts still active.

Come back in a little over an hour and the FF tab reload isn't working as described earlier. Stop NoScripts and tabs finish reloading.

Now is this a Noscript 11.4.18 or FF 111.0 issue, I did both at same time. Prior to that I was on FF 110.0.1. Currently running Windows 10 64 bit, haven't done the March update as nothing much there. All was fine until FF and NoScript update. All is fine until FF runs for awhile. For now I just turned NoScripts off.

I am attempting to disable the Recent Bookmarks section from the bookmarks menu in Firefox Windows version 111. The main solution that's been suggested in the past is to use about:config and change browser.bookmarks.showRecentlyBookmarked to false.

This setting appears to be ignored in my version as changing it has no affect.

Any other steps?

Hello support team.

My Firefox does not ope any wensite. It shows just error code: PR_CONNECT_RESET_ERROR. I found a few solutions in Internet, but it doesn't help. I tried to reset Firefox, install new version, create new profile and etc. It does not help. Please help me to solve my problem

All new tabs give me a cursor in the ADDRESS BAR. This is unacceptable. There is a nice search window in the middle of the page, but the cursor never goes there. It appears in the ADDRESS BAR. I did the about:config handoff crap and it was crap. Is there a FIX? If so, what is it? If not, I'm using edge.

I use Firefox to access Facebook live, from which I live stream. Starting in the last few weeks (I don't know when exactly, sorry), I now get this error message (in the stream Event log) when I stream:

Too low key frame rate (currently 0.13 key frames/second; recommended minimum 0.25 )

And I get a separate warning from Facebook that the key frame rate is too low, and will result in poor video quality.

If I stream from Chrome, I don't get the error (but Chrome has other problems), so I think it must be related to Firefox. Is there anything I can do about it? Thanks.

in firefox windows: I don't know the technical terms for this, so don't assume I'm using "reload" correctly - or anything else. every time i switch back and forth between tabs, the tab i return to suddenly goes blank and reloads. It can take 1-15 seconds every time I switch tabs, but sometimes I can switch back and the tab is the same as I left it without blinking out and into existence. On certain sites, this makes whatever I was reading get lost in the feed, but it's always distracting and frustrating. I work fast between lots and lots of tabs and this eats a lot of time and makes me lose focus, and adds massive friction to my workflow. How do i make it keep tabs loaded and looking as they did when i switched out of them, instead of pretending I just typed in the url and loading that from scratch every time? I'm not the best with technical terms if anybody knows this can you explain it like I'm five please? Pictured: a tab I switched out of a little while ago but needed to copy something off - it went blank and slowly re-loaded when I switched back over to it

for some time now im having problems with your site, works ok then slows down click on a link and nothing i then go into safari and i have no problem if you can not rectify my problem i will start using Safari instead, had this problem now for sometime

Is there a simple method to turn off the annoying popup notifications about upgrading Firefox? I don't want to upgrade, FF seems to be working fine. Sometimes updates bring new problems.

I'm not a programmer, so I'm hoping there is a simple fix to stop update notices. I think it was a bad idea to have them appear in front of other websites. They often popup when I'm watching something on Netflix.

Hello,

Everytime when I open the FF I see the white space on the screen, please check the screenshot.

After I press F11 two times I see borwser normal again.

Thank you, Danijel

When I try to google some absolute file path (e.g. /etc/fstab) in the address bar, instead of googling, it just opens the file from my local filesystem (as file:///etc/fstab)

I know that I can use search keywords or quote file paths, but even so, I think that users hardly ever use browsers to open local files by absolute url. So this UX totally disappoints me because I need to keep this in my mind every time I want to google file or I lose my mental concentration and then I need to change the focus from solving my issue here and now to fixing this misbehavior

Can I somehow fix this behavior with about:config?

This release changes the function of the 'wheel' on a mouse.

Instead of scrolling up & down a page, it now 'zooms' in and out.

Is this deliberate? Or, is it a bug?

Microsoft USB Basic Optical Mouse v2.0

I recorded USB webcam pictures with MJPG_streamer and converted them to mp4 using

  ffmeg -r 20 -pattern_type glob -i "*.jpg" -c:v libx264 test.mp4

Firefox complains "video can't be played because the file is corrupt" Google Chrome and VLC have no problems playing the file.

What options for ffmpeg do I need to create the mp4 files so that firefox can play them?

Hi, I have been using firefox for a long time and have been quite happy with it, but not so long ago (I suspect that it started happening after the update from 14.3.) I have begun experiencing a really annoying bug/feature and have not been able to fix it myself.

The Bug: When watching any video on any site with fullscreen on, after going to desktop and back (with the three finger down gesture on the touchpad and then three fingers back up) to check the time, the video playing suddenly minimizes (goes out of fullscreen mode) and the whole site goes into fullscreen mode, just as if I have pressed f11 which i didn't a aslo dont want, i know that it seems as a minor issue but it is extremely frustrating as I have been using this for a long time now, and i cant just check time like this anymore.

What have I tried: I have tried doing this in incognito, disabling all addons, messing with settings, trying troubleshooting mode, logging out, and doing the same thing in chrome which doesn't do it.

If anyone has any advice, i would be very grateful, thanks.

Hi I have recently posted an issue of mine so I have decided to ask about this as well.

The Problem: On my schools website there are records of my schools lectures. When I try to load them on the page they just load infinitely and don't play, I can even try to open them up in a new tab and the same happens. Sometimes i get lucky and they play without an issue for a while and then stop and infinitely load again, the funny thing is it happend on the exact spot twice. It isn!t an issue of my wifi or the school's server as the videos load on chrome just fine.

What have I tried: I have tried doing this in incognito, disabling all addons, messing with settings, trying troubleshooting mode, logging out, clearing out cache and cookies.

I would be very grateful if anyone has any suggestions,

Thanks.
