Firefox-Hilfeforum

Whenever I have Firefox open on Windows 11, my windows key doesn't work. I can assure that its Firefox because whenever I close it, the windows key starts working again. This is really annoying because I normally use the keyboard and having to move my mouse to the bottom just to open the menu gets annoying quick.

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?

Please see the attached screenshot. I get this popup EVERY TIME I open FireFox. I've tried a number of different suggested "fixes" from Google Searches with no success.

I want this popup GONE.

When you added a bookmark to a site in Firefox there used to be an option that when you hovered over the bookmark a dropdown would appear showing recent changes or additions to the site (see attached). It doesn't seem to be there any more - is there any means of restoring it? Thank you.

hello everyone; i have a strange issue with my yubikey and firefox on redhat linux 8. (i can't upgrade to red hat 9 and it's technically oracle linux)

its works fine for the first x hours (where x is usually between 1 and 3 hours) and then firefox will invariably stop recognizing the yubikey touch. yubikey works with any other application in that journalctl shows that systemd is aware of it's existence when i plug/unplug it and i get a string in my terminal and text editors whenever i touch they key both before and after it stops working with firefox.

i've tried these things but the behavior is still the same: - regenerating my ~/.mozilla configuration directory - toggling all *webauth* keys in about:config - switching from yum to flatpak firefox installation - switching from gnome to kde to xfce - switching from Wayland to X11

there are no error messages; journalctl doesn't show any either; and chrome doesn't seem to have this problem, but i don't trust chrome and, interestingly, chrome exhibits the same behavior when using xfce.

the only thing that works reliability is rebooting each time it happens and, as you can imagine, that's 100% intrusive and i lose all momentum in my productivity.

here's details on my system:

Firefox version: 115.10.0esr (64-bit)

OS: Red Hat Enterprise Linux release 8.9 (Ootpa) Oracle Linux Server release 8.9 5.15.0-205.149.5.1.el8uek.x86_64

X Windows info: gnome-session-wayland-session.x86_64 3.28.1-21.0.1.el8 @AppStream libwayland-client.x86_64 1.21.0-1.el8 @AppStream libwayland-cursor.x86_64 1.21.0-1.el8 @AppStream libwayland-egl.x86_64 1.21.0-1.el8 @AppStream libwayland-server.x86_64 1.21.0-1.el8 @AppStream qt5-qtwayland.x86_64 5.15.3-1.el8 @AppStream xorg-x11-server-Xwayland.x86_64 21.1.3-12.el8 @AppStream

I have support licensing from both Oracle and Yubikey and i've asked them for help and they both point the finger at each other so i'm stuck with this; any help would be appreciated!

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

• Restart Firefox
• Started Firefox in Safe Mode
• Restart computer
• Create a new profile in Firefox
• Check my mouse's firmware
• Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

I am having the same issues as the person in this thread, but unlike their situation, firefox has not fixed itself out of nowhere. https://support.mozilla.org/en-US/questions/1104044

Everything in the firefox browser looks like it was stretched it out in MSPaint, while my actual OS interface and every other app/software UI looks fine. I have tried simply restarting my computer, as well as every solution in the linked thread, as well as refreshing firefox, and uninstalling/reinstalling, which only served to mess up my shortcuts on the home page. To be clear:

• Hardware acceleration is turned OFF, as suggested in any thread I've found where a resolution issue is addressed.
• setting layout.css.devPixelsPerPx to 1.25 specifically makes it almost legible. Almost. It's still incredibly grainy. Any higher even a small portion of a webpage takes up a ridiculous portion of my screen, rendering it just as unusable.
• In messing around in config, I found that setting gfx.color_management.rendering_intent to 5 helped, in so far as it sharpened things up a little, but it did not FIX the issue. Any value above 5 seems to have zero effect or change.
• Absolutely EVERYTHING else except firefox looks absolutely fine. It is ONLY firefox that is having this issue of all the applications/interfaces on my computer.
• Everything in firefox is affected- images, text, the tabs and address bar, bookmarks bar, absolutely everything.

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

I'm running Firefox 102.4.0 ESR (32 bit) on a Win-7 (32 bit) PC.

It works fine. I visit a LOT of websites, it works fine.

Until just now. I'm trying to bring up namecheap.com (a domain registrar) and I'm getting this message:

Secure Connection Failed An error occurred during a connection to www.namecheap.com. security library failure. Error code: SEC_ERROR_LIBRARY_FAILURE

I'm not given any option to alter any FF settings or to otherwise create an exception to "trust" this site to be able to access it.

I've read where changing security.pki.crlite_mode (currently 3) to something else (like 0) and I've tried that, and unless I have to close and restart FF for that to take effect (which I have not done) then that setting doesn't fix the issue.

What exactly is going on here? Why is only THAT SITE giving me problems?

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.
