all my tabs from open session disappeared?!?!?

and no way to restore it; the option disappeared and I never erased it or close any of the tabs manually and it was on sync. Where did they all go ? I can see now the history from my laptop mixed with my mobile under the history tab but the session disappeared?!?!

Firefox use to be EXCEPTIONAL and 2 years ago it star5ed to go downward; please convince me to stay loyal and not switch to brave or opera; this is becoming worst every months.

I did everything I found with ChatGpt and nothing works:(## Recovering Lost Tabs in Firefox Android

I understand that all your open tabs in Firefox Android have disappeared, even though they are synced. Don't worry, there are ways to restore them and reopen that session on your mobile device.

• • Here are the steps to recover your lost tabs:**

• • 1. Check Recently Closed Tabs:**

• Open Firefox on your Android device.
• Tap the three dots menu in the top right corner.
• Select "History" from the menu.
• Choose "Recently Closed Tabs" from the History list.
• This will display a list of recently closed tabs. If you see the session you're looking for, tap on it to restore all the tabs.

• • 2. Use the "Restore Previous Session" Feature:**

• If the "Recently Closed Tabs" option doesn't work, try the "Restore Previous Session" feature.
• Open Firefox on your Android device.
• Tap and hold the "Home" button.
• A pop-up menu will appear. Select "Restore Previous Session".
• This will restore the last browsing session you had open, including all the tabs.

• • 3. Check Your Synced Devices:**

• If the above methods don't work, check if your lost tabs are open on another synced device.
• Open Firefox on your computer or another mobile device where you are logged in with the same Firefox account.
• Look for the lost tabs in the "History" or "Recently Closed Tabs" section.
• If you find them, you can open them on your Android device by syncing your browsing history.

• • 4. Contact Firefox Support:**

• If none of the above methods work, you can contact Firefox support for further assistance.
• You can reach them through their website: https://support.mozilla.org/en-US/products/firefox/fix-problems/
• Explain your situation and they will try to help you recover your lost tabs.

• • Additional Tips:**

• To prevent this from happening again, consider enabling the "Open Tabs in Background" setting in Firefox. This will keep your tabs open even if you close the app.
• You can also set Firefox to automatically restore your previous session when you open the app.

• • I hope this helps you recover your lost tabs and reopen your session on your mobile device.**); is there a way im missing ?

Only thing that happened is that I restared my phone earlier?!

I just started getting this error:

Secure Connection Failed An error occurred during a connection to www.newsmax.com.

I cannot find how to make this stop. I will get emails from Newsmax about articles and if there is something I want to read I click on the link in the email. I never had a problem with Firefox not opening the link. This just started and I can not get the link to open. I have Newsmax set up as a home setting. However, after I got the Secure Connection Failed error, I could not open the Newsmax web page even if I typed in www.newsmax.com. I am about to uninstall Firefox and use another browser. Can you please tell me how to fix this?

When trying to use one particular website on Firefox, I get a message that I am blocked because of an ad blocker but I have not turned on any ad blocker in Firefox. How do I find out if an ad blocker is enabled on my Firefox and, if so, how do I turn it off? I have ensured that the ad blocker option in settings is unchecked and even added this web site to permissions but to no avail. Can someone help? Here is the message I get but none of the steps in this message I am told to take show up on my screen:

Adblock Plus Instructions

   Click the AdBlock Plus icon in the extension bar.
   Beneath “Block ads on”, click the large blue toggle next to “This website”.
   Click refresh.

Were these instructions helpful?

Hello. Since re-installing ZoneAlarm Security Suite (due to a ZA problem) last evening, after I turned on my pc today I am getting a new tab opens up on every FireFox browser window seeking permissions for "Harmony Web Protection Privacy Policy". (There are four new tabs for that which have opened since I commenced typing this!).

Is this a ZA problem or a Firefox problem? Also, please, how do I get rid of these damned new tabs? TIA.

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

Conditions

System: Linux Fedora fc20.x86_64, CPU i520M, 3.66 GiB RAM on DELL E5410

Libraries have been updated from rpm packages of Fedora distribution fc21.x86_64 to satisfy the requirements for Firefox 128 and now following versions of relevant libraries and packages are installed:

X.Org 1.14.4, libstdc++ 4.8.3, glibc 2.18, libglib 2.42.1, GTK+ 3.14.5

NetworkManager-0.9.9.0, dbus-1.6.30, GNOME 3.10.0, PulseAudio 5.0

Updating to newer version of Fedora is not possible option for me now.

Firefox 128.0.3 tarball has been unpacked to /usr/local/lib64/firefox128

Executable bash script, /usr/local/bin/firefox128 has been used to launch Firefox 128, it contains two lines

export LD_LIBRARY_PATH=/usr/local/lib64/firefox128:$LD_LIBRARY_PATH /usr/local/lib64/firefox128/firefox $1

Existing file $HOME/.mozilla has been temporarily renamed to avoid hardly possible conflicts while testing the new version of Firefox. (Later I have found that this is not necessary because new installs

of Firefox do not conflict with the previous).

Problem

Execution of the bash script, firefox128 from gnome-terminal command line started Firefox 128 but without GUI. Only the small white interval at left upper corner of the desktop appeared and it could be extended by using mouse to empty (white) window created by Gnome and titled, Firefox.

Observations

After Firefox 128.0.3 started the output of the command, ps -flu username revealed,

      /usr/local/lib64/firefox128/firefox
      /usr/local/lib64/firefox128/firefox-bin \
           -contentproc -parentBuildID 20240725162350 \
           -prefsLen 21615 -prefMapSize 245327 \
           -appDir /usr/local/lib64/firefox128/browser \
                   {d54171b1-8a79-44b3-a271-db4e09db2365} 3715 true socket

Two parameters preceding `true socket` vary from launch to launch.

Executions of, firefox128 --help

              firefox128 --full-version

display the expected output

In the way of successive approximations to highest Firefox version that starts with GUI in my system I have found this is Firefox 95.0.2

The binaries firefox in Firefox versions from 96.0 to 99.0.1 do not launch firefox-bin and the application hangs requiring explicit kill

Firefox versions 100.0.2, 101.0, 106.0, 106.0.5, 117.0, 117.0.1, 123.0.1, 128.0 I have tested like Firefox 128.0.3 behave in the same way as Firefox 128.0.3 with the same effects.

Output of the command, ps -flu username obtained when Firefox 95.0.2 is running with GUI in my system differs specifically from outputs of this command for Firefox versions above 100 Last argument for firefox-bin in those Firefox versions i.e. 100.0.2 and newer is `socket` whereas in Firefox 95.0.2 the last argument is `tab` as in the case,

       /usr/local/lib64/firefox95/firefox-bin \
                    -contentproc -childID 2 -isForBrowser \
                    -prefsLen 4814 -prefMapSize 241644 -jsInitLen 278884 \
                    -parentBuildID 20211218203254 \
                    -appDir /usr/local/lib64/firefox95/browser 9563 true tab

       /usr/local/lib64/firefox95/firefox-bin \
                    -contentproc -childID 6 -isForBrowser \
                    -prefsLen 5627 -prefMapSize 241644 -jsInitLen 278884 \
                    -parentBuildID 20211218203254 \
                    -appDir /usr/local/lib64/firefox95/browser 9563 true tab

       /usr/local/lib64/firefox95/firefox-bin \
                    -contentproc -childID 7 -isForBrowser -prefsLen 5627 \
                    -prefMapSize 241644 -jsInitLen 278884 \
                    -parentBuildID 20211218203254 \
                    -appDir /usr/local/lib64/firefox95/browser 9563 true tab

During executing both the bash scripts firefox128 and firefox95, launching the respective Firefox versions, Firefox writes messages to stdout (gnome-display) but the outputs do not differ qualitatively.

For firefox128 the only intriguing mesasage is the last one that appears while closing Firefox 128, [GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

These messages not differing qualitatively for Firefox 95.0.2 and Firefox 128 can be summarized as follws (firefox:5370): Gtk-CRITICAL **: gtk_widget_get_style_context: assertion 'GTK_IS_WIDGET (widget)' failed gtk_style_context_get_state: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed gtk_style_context_get_property: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed gtk_style_context_get_background_color: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed gtk_style_context_get_color: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed

(firefox:5370): GLib-GObject-CRITICAL **: \ g_value_unset: assertion 'G_IS_VALUE (value)' failed

(firefox:2901): GLib-GObject-CRITICAL **: \ g_object_ref: assertion 'object->ref_count > 0' failed and g_object_unref: assertion 'object->ref_count > 0' failed

[GFX1-]: glxtest: libEGL missing methods

For Firefox 128 they are preceded by warnings like, [Parent 4185, Main Thread] WARNING: \ g_value_unset: assertion 'G_IS_VALUE (value)' failed: \ 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:187

Moreover during starting Firefox in versions 96.0 - 117.0.1 there is the message,

                    os_mmap failed.: Cannot allocate memory 

This message is absent either in Firefox 95.0.2 and Firefox 128.0, 128.0.3

Motivation

The effect just described looks very strange but may be common to older versions of Linux distributions still being used by number of people with various motivations.

Various institutions, particularly banks, require "newest" versions of a browser and I am afraid that Firefox 95.0.2 working in my system will be very soon considered outdated that will result in lack of electronic access to bank account.

Therefore solving the problem just presented appears to be important.

Thank you in advance

I've attached images of the problem I'm experiencing. Its like pixels are breaking/turning negative colors and it effects anything visible. I don't really understand what's causing this issue. It doesn't effect any other program on my computer/outside the firefox window, so I assume its a firefox issue. I've uninstalled/reinstalled the program with the refresh to hopefully fix the issue but it didn't work.

I've got a question/suggestion about Picture in Picture feature. Why "Close" button works the same as "Back to Tab"?

Scenario: Close the Picture in Picture video by clicking on the [X] button or Cmd+W shortcut.

Actual result: Picture in Picture closes and Firefox window opens, on the tab containing the video. This is very strange behaviour. If I close the video, I don't want to watch it now. Essentially "Close" button works exactly like "Back to Tab" button - so what's the point? If I wanted to switch to the tab - I would click on "Back to tab".

Expected result: I expect Picture in Picture video to close and nothing else to happen. Don't open the window/tab containing the video.

Thanks

For the last 2 weeks I started having problems with Firefox working consistently. Sometimes only tabs crash, sometimes Firefox crashes. It is not tied to any actions, a tab can crash even if you don't perform any actions in the browser. I have tried clean install on Fedora and Vanilla OS, native and Flatpak packages. The result is always the same - tabs or Firefox crashes every few minutes.

I don't want my search queries to be saved in the firefox search bar. I usually open a new tab with Ctrl+T, hit Ctrl+K to go to the search bar and hit enter without any keywords. This opens the search engine page (in my case google.com)

Now hitting enter with an empty search bar does nothing. Started happening with the new version 128.

Is there a shortcut alternative to opening the search engine in a new tab?

PROBLEM: After a restart of Windows 10 and re-starting Firefox, a Firefox window with a YouTube web page in a tab will start playing unbidden. When multiple Firefox windows with multiple tabs each are in use multiple YouTube videos will start playing. (Only one of possibly multiple YouTube tabs per FireFox window, I believe.) The cacaphony is annoying. Tracking down the offending tabs is difficult. (There is no "Show tabs playing media" feature in Firefox.)

QUESTIONS: (1) How do I prevent Firefox from playing media (YouTube and others) unbidden when Firefox re-starts and re-loads its tabs? (2) How do I quickly find which Firefox windows have a tab that is playing media? (3) How do I quickly find which Firefox tabs are playing media? (4) How can YouTube videos be prevented from automatically starting when a Firefox web page with that video is re-loaded?

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

Hello - I've noticed lately that when I type a search, sometimes Firefox does nothing. It doesn't pull any results, it acts like I've done nothing, but I can see the search terms I typed in the address bar, separated by + symbols. It simply doesn't go anywhere and doesn't perform the search. I do a lot of searching when I'm working and this happens approximately 1 out of every 15-20 searches. I've attached an image where I opened a new tab, typed my search term and it remains on the homepage. You can see the search terms in the address bar.

When I play any video on https://www.bilibili.com/ this chinese website After finish the video,The Firefox get white screen and crash And this happen every single time, There is nothing I can do The crash log is here: bp-c489f92a-e918-43ba-ab0b-589210240812

Hello support. Since your last update, the "Allow cookie" popup is no longer displayed in the Firefox incognito tab on our site which leads to all functions being blocked. We have tried to identify the problem, but on different computers with the same (current) version of Firefox, we have the result that sometimes the popup is displayed and sometimes not. Why does Firefox block our “Allow cookies” popup in the private window?

Hello, I have Firefox 128 installed on Window10 Pro v. 22H2 fully up to date. I have LastPass: Free Password Manager extension in my Firefox.

Up until 2 days ago I had an icon on my toolbar for the LastPass extension that I could click after opening Firefox to login to LP. It has worked fine for years. It was that way when I shut down my computer that night. The next morning when I opened FF, that icon was gone. LP still shows in my Add-ons manager as Enabled. To the best of my knowledge, nothing on my comp updated in that time period.

I tried clicking the 'Extensions' button in the FF toolbar, but all it did was to open the "Recommendations" tab of my Add-ons manager. Previously, clicking the 'Extensions' button in my toolbar would show a menu of extensions including LP. I would get an option to show an LP icon in my toolbar. That worked as recently as a few weeks ago when I wiped my hard drive and did a fresh install of Windows.

I tried removing and reinstalling the exension. It made no change. Next I fully removed Firefox with the Remove Programs option in the Windows control panel, then removed all traces of FF in my Windows user profile. Then rebooted. Then DL'ed Firefox fresh from the FF site and re-installed it. Twice. No icon shows up, and the 'Extensions' button continues to do nothing but send me to the 'Recommendations' tab of the add-ons manager.

I had a few other extensions installed as well as LP at the time this problem arose. But when I re-installed Firefox, I only installed LP and tried to get its icon showing before installing any other extensions, just to be sure there was no conflict.

Can you offer any suggestions to help?

Thank you.
