I'm not sure when it happened, but somewhere along the line, Firefox stopped showing on-hover tooltips on unfocused windows. Clicking into the Firefox window again can disrupt what I'm doing in another window, however. For example trying to hover on the Firefox window with my mouse cursor, and type the text of the tooltip into a different window, while leaving the tooltip visible. Wrecks that idea!

I guess I assumed it'd be a temporary issue, that'd get resolved in a later update, without having to say anything about it, and I was wrong about that.

Any idea what's up, and how to get the tooltips to work as I would like them to?

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 have the following settings in Settings/Preferences>General:

Files and Applications

Downloads Save all files in the following folder: Downloads Ticked Ask every time where to save a file

Applications Portable Document Format (PDF): Open in Firefox How should Firefox deal with other files? Ticked Ask whether to open or save files

On specific websites when I click on a pdf link, Firefox opens and automatically saves the file to Downloads folder without asking whether to save and where to save despite the above settings. As far as I remember, on other websites when clicking a pdf link Firefox only opens the corresponding file and doesn't save.

I found this with a internet search https://connect.mozilla.org/t5/discussions/stop-saving-pdfs-to-downloads-when-viewing-in-firefox/td-p/10225.

How can it be disabled that Firefox automatically saves PDFs?

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

Hello,

I tried opening an .md file with Firefox. It seems that this was a bad idea. Now, my browser keeps opening new tabs indefinitely. I tried rebooting my computer (I am using Ubuntu), I tried removing the handlers.json files from the .modzilla folder in my home directory, but it has no effect: whenever I try to open Firefox this infinite loop goes on right were I left it closing the browser. Please help so I can use it again! Best.

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Lately, Firefox unchecks the 'use autoscrolling' and 'play DRM-controlled content' options sometimes (but not every time) when it starts. Other settings don't seem to be affected. It does seem to unset both at once, never one or the other at a time.

I have begun using Firefox routinely on two computers, both signed into the same sync profile. My best guess is that maybe one profile is overwriting the other? Both of these options are set on the second system, but maybe there's something going wrong with the sync?

Thanks, Patrick

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

I get the message under Settings: "Your browser is being managed by your organization". Clicking on that message shows that the policy DisableAppUpdate is true. Methods for remeding this situation do not work. Please advise on how to change the policy to allow update please

I have a locked file that shows up as Invalid Symlinks error. I am not sure but I think it may be Profile.ini Here is what I am getting that tells me its a Non-Existent Destination file. My question is why is it Invalid symlink and what can I do to fix it? Here is what I get: Lock In symlink folder /home/butch/.mozilla/firefox/6q1a4nt2.default-release 127.0.1.1:+2708 type of error Non-existent Destination File 2022-03-08 21:15:25

When I deleted it wouldn't open so I had to completely reinstall it. My Email address is: [removed email from public]

Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.

What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:

gfx.webrender.all = true general.smoothScroll.mouseWheel.durationMaxMS = 400 general.smoothScroll.mouseWheel.durationMinMS = 200 mousewheel.min_line_scroll_amount = 40 mousewheel.system_scroll_override.enabled = false

To post on this support forum I just created a Firefox account. The system then emailed me a verification code to check my address. While nearly the entire email was in English, the time seemed to be rendered in Greek. This seems a bit odd to me. My browser is set to English, with no other languages present. My IP address is in the Netherlands. See the contents of the email below.

Cheers, Maarten

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

I had a number of tabs open today (~40). Because Firefox started to malfunction, I had to restart Firefox. It happened to me before and I knew that I can restore my previous session so I safely closed the tabs.

When I restarted it, I opened a tab and then I tried to open the Application Menu, but accidentally closed the window. Now, when I've re-opened Firefox and attempted to restore the previous session only that last tab appeared.

Is it possible to recover the pre-previous session? I use Ubuntu 18.04. Where is this information located? and how can I retrieve it?

Got sick and tired of having to enter payment card info every time, so I decided to RTFM and follow instructions. I worked my way thru all the instructions on found on the forum pages, and was entering the information via about:config, and got to the popup where I was asked to confirm, and clicked the button, then clicked it harder, but nothing happened.

My guess is that my Firefox and/or my Leap15.3 installation has left some file permission read-only and Firefox is unable to save this bit of data, but I really don't want to run Firefox as root. I can say more, but I see there are more boxes to fill.

So, I included a screenshot of what I hope will be the useful part of my config file.

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.
