I had about 15 pinned tabs - unloaded - that I was saving for a research project. I shut my PC down and when powered up for the next session - all the pinned tabs were gone. I never thought to record the tabs via screen shot or something.

Is this normal - what are the limits of pinned tabs ? Do they expire in a day ? When the PC powers down ? When Firefox updates ?

Exactly what are the limits or boundaries for pinned tabs ?

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

Hello Folks, I just importeda a new certificate. Then I wanted to save all my certificates for backup. Selecting "Backup all...", I neter a secure password and click ok just to get the following error message: Failed to create the PKCS #12 backup file for unknown reasons the only button is "OK"

How can I start finding out what is going on and is there any means to save my certificates?

A few weeks ago, I started to get repeated messages from Firefox asking me to make Firefox my default browser. Firefox has been my default browser for years, and I have never made anything else my default browser. Anyway, I followed the prompts and re-selected Firefox as my default browser. A little while would go by (sometimes as little as a minute) and I would again get the prompts to select Firefox as my default browser. This append 20 or 30 times. And, every time it happened, all of my saved passwords disappeared, but would reappear when I re-selected Firefox. In the last week, this situation has gotten a lot worse. Now, the saved passwords don't come back. And, the prompt you usually get when entering passwords to a new site offering to save the password doesn't appear any more. So, the only way I can rebuild my saved passwords is to enter them manually, which I am not going to do because it would take a couple of hours and then I'm pretty sure they would all disappear again. Also, I like to go to my homepage when I open a new tab. Can't do that anymore. When I open a new tab, I get a new private browsing window. I have checked all my settings a dozen times, and they are correct. I have combed your support sites and there is nothing there to help me. I don't want to dump Firefox, but I cannot continue with it behaving as it does now. Is there anyone anywhere in your organization who can help me? Thank you.

1. 1. Steps to reproduce

Open several tabs, in settings, check «ouvrir les fenêtres et onglets précédents», quit firefox.

1. 1. 1. Expected behavior

On startup, Firefox should reopen with the same tabs before shutdown.

1. 1. 1. Actual behavior

Firefox opens with one empty tab. Forcing me to got to «history -> recently closed windows -> restore» everytime I quit Firefox or shutdown the mac.

Fresh migration from Win 11 to Mac. tabs, passwords, bookmarks, plugins migrated from win to mac. Attachments:

What is wrong with firefox! It doesn't work right with benzworld.org a mercedes forum. Page becomes unresponsive, or when clicking a link for a thread it takes incorrect page. Other browsers don't have this problem. Saving a bookmark, it doesn't save. Uninstall, reinstall, same thing.

Firefox autofilling my freaking CC number though those settings are disabled. I want to know what Firefox file my CC number is stored in.

Give me the filename -- I'll do the rest...

It is with deep regret to inform you of my discontinuation of the use of Firefox.

My issues began at the beginning of February this year and have continued and compounded to the point that I cannot continue its use. The issues are constantly logging me out of my account, disabling ALL my bookmarks and the loss of well over a hundred passwords. I have followed every help article and community forums help links and to no avail I'm still dealing with all the same issues. I've have to restore my links every time I'm logged out of Mozilla. Their are no passwords to restore except for the Mozilla account I just had to log back into.

Again, I do regret discontinuing its use. I have used this browser for well over a decade and I am not one for changing anything at this point in my life. I'm 67 and having to switch is indescribably painful. I actually think your integration of AI functions are the problem. Everything was just fine before that was introduced.

If you have any comments, please feel free to email me at my former account email address.

Farewell old friend.....

I already have Firefox on my laptop and via Mozilla I was asked again to install Firefox. Furthermore I always got the question that I should use it as standard browser. I have no idea what else should I do in that case. If I would install again Firefox, I will lose all the paid apps which run already on the current version. So I am really very confused about the characteristics of this Firefox installation and the strange requests by Mozilla to install Firefox.

I would be delighted if you could me support with checks to find out about the nature of the current Firefox installation or a simple de- and reinstallation instruction of Firefox (and keeping the paid apps like Ad Blocker...).

Thank you in advance for your feedback

Since about mid january, the language of documents at my homebank, is switched from the original danish langguage, to english. With Google Chrome browser, it is still danish. See attached scree print. Left originl danish, right - strange - english. As far as I have found out, there was a SW update of Firefox late January, that could have introduced this fault. I have had contact to Homebank supporter, of course. Their first question was: Switch to danish langue. But is is, as it has been foir several years. Please help me! Also I have some other minor problems, as many homepages do not test changes with Firefox. I do not want to list it here! So I ask you to make less special SW for Firefox, otherwise you will lose many users. It is NOT OK as it is.

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?

I use Brave, Firefox, Firefox Developer Edition and Thunderbird. Brave: 600mb Firefox Dev: 600mb Thunderbird: 200mb Firefox: 800mb Why is Firefox using too much memory? Especially as I am running Firefox Dev as a direct comparison. I don't have any plugins on Firefox. Firefox Dev has uBlock Origin alone. Brave has a few plugins.

Duck duck search via Firefox has become painfully slow, although if Google search is used the speed is OK. I have cleared caches, cookies etc without any improvement. Firefox 148.0.2, Windows10. Is this a recognised current problem?
