Firefox Community Forum

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.

I have had this problem in the past, but now its back again. At first I just reset my password every time, then I set up the password to be auto-filled. I have had no sign-in failures for months. At one point i did figure out how to check my sign in history to see the failed attempts, and there were none. That was a long time ago, and I have since forgotten how to check this. The problem does seem to be with firefox as it does not happen with chrome.

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 ?

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!

While this may sound silly, it does happen that I add bookmarks, but I might rush and forget to update/change the bookmark folder/path where to save it when I am in a hurry (and the page might end up saved, but not in a location I want, say, a news article that should be saved in "News" might end up in a "Development" bookmark path or vice-versa, depending on which path I last used to bookmark a page), or even forget where I saved it (if I did it some time ago for a "read/use/check/update later" type of thing and it is a generic article - and yes, I even have a "TODO" bookmark "directory").

While the Bookmarks windows dos have a search option (thank god!), it doesn't also show where I saved said bookmark (so that I can move, delete or do whatever to it). So please, in the Bookmarks window also add a column with the path where it is saved (obviously hidden by default), along with the URL, name, visit count, etc. I am sure code-wise, the effort is negligible, but it can help so much.

Hoping this comes true (*fingers crossed*), thanks in advance!

Ich habe eine Systemwarnung halten und habe versehentlich angeklickt. Defender hat einen Trojaner entdeckt. Dieser wurde entfernt. Jetzt wollte ich Firefox restaurieren. Wie ist das möglich. Was ist zu tun ?

What seems like ages ago Firefox stopped displaying bookmarks I addition it would not add new bookmarks nor restore the existing ones. I've gone through all of the corrective procedures listed on and off but nothing works. As a final attempt I deleted the program and reinstalled it. No change. It seems to me that perhaps a missing file from another program or system is missing. Maybe!

I have been using an alternate system for some time. When installed it had no problem finding all of the Firefox bookmarks and placed them on the menu bar as "Firefox Bookmarks". I have no issues with using them but all new ones are stored in the current browser. Thus the new ones do not go into the folders previously set up. I've avoided moving them manually to the new system due to the volume but I am ready to bite the bullet.

I prefer Firefox but it's just not working.

Can anyone save Firefox for me.

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.

I really appreciate Firefox's built in translator; it is extremely helpful. However there is one thing that bugs me, when translating a page that has multiple language options. For example, when translating a page from German to English, the word "Deutsch" (often listed in the website's built in language settings) is translated not to "German", but to "English". While technically correct in that the page is now displaying English thanks to the Firefox translation, it would probably be better to show "German" so that it is easier to switch the website language and not have a duplicate "English" option in the website's dropdown menu. I have noticed this on multiple websites, specifically with German, but it might be with other languages as well. Hopefully this explanation of the issue makes sense, and see my attached screenshot which shows this issue. Please let me know if there is somewhere else I should submit this too.

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...

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

After a usual, recent automatic Firefox update my passwords and other data (bookmarks, history etc) are missing. The update took place around March 4 and on March 10 I used Smart Switch by Samsung to transfer and sinc my phone data on my pc. After this operation I noticed the missing data and all attempts for the various methods to restore data were unsuccessful. Please advice on how to restore passwords etc..
