All of a sudden, when I hover over a tab, a small window of the web site that tab is in, appears. Never happened before.

I did go into Performance Options - Visual Effects and unchecked "enable peek," but it didn't work.

How do I stop these windows from appearing?

Windows 10.

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

Hi All,

Is there a way to replace the navigation icons on the context menu with their text-only counterparts?

I've tried the following code segments which provide less-than-optimal results.

This one which worked in FF 88, now removes the icons, but leaves 4 blank buttons in a row with no text...

#context-back image,
#context-forward image,
#context-reload image,
#context-stop image,
#context-bookmarkpage image {display: none !important;}}

This one completely removes the options, but I would like to keep them, and replace them with their text counterparts

#context-navigation,
#context-sep-navigation {
   display:none !important;
}

Please see attached images for the before and after of what I'm trying to achieve.

Might be nice to have the blank icon column to the left of these 4 items so they all line up with the items below, but I can live without that if it's not possible.

Any help is appreciated!

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

For about the past week I've been having trouble with Gmail and Google Search in my Firefox browser. Typically, I open a Firefox window with multiple tabs and leave the window open all day. I always have Gmail and Google Calendar open in tabs. What happens is that the Gmail tab will at some point give me a message that it cannot connect and has timed out and is trying to reload, but it never reloads, it just stalls. Then I try to open a Google search bookmark to search and the tab remains blank. This happens multiple times throughout the day. Meanwhile I can open Gmail or any Google page in Chrome, which I don't like using.

Sometimes I can close out the Gmail tab that won't load and try to open Gmail in a new tab, but that stalls out too. The only way I can open Gmail again is to close out the Firefox window completely and then relaunch it, then it can open Gmail or Google... until it breaks again.

This never used to happen. I'm using the latest versions of Windows 10 and Firefox on my desktop PC. Nothing else has changed.

Please help me fix this, it's very annoying.

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something [edited] do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.
